Health ConditionsToothaches, also known as dental pain or tooth pain, is pain in the teeth or their supporting structures, caused by dental diseases or pain referred to the teeth by non-dental diseases. When severe, it may impact sleep, eating, and other daily activities.
Toothache occurs when the innermost layer of the tooth (dental pulp) becomes inflamed. The pulp is made up of sensitive nerves and blood vessels. It is caused by inflammation of the dental pulp — the nerves and blood vessels inside our teeth. When the pulp becomes inflamed, this is called 'pulpitis'.
Dental caries is a major public health problem globally and is the most widespread noncommunicable disease (NCD). Dental caries is the most common noncommunicable disease globally, affecting 2.5 billion people worldwide. It is estimated that 2 billion people suffer from caries in their permanent teeth, and 510 million children have caries in their deciduous teeth.
Toothache can be felt in many ways. It can come and go or be constant. Eating or drinking can make the pain worse, particularly if the food or drink is hot or cold. The pain can also be mild or severe. It might feel sharp and start suddenly. It can be worse at night, particularly when you're lying down.
Symptoms may include persistent toothache ranging from dull throbbing to sharp pain, especially when chewing or applying pressure, and increased sensitivity or discomfort when consuming hot, cold, or sweet foods and drinks.
Periodontal pain is frequently localized to a particular tooth, is made much worse by biting on the tooth, is sudden in onset, and is associated with bleeding and pain when brushing.
The tooth pulp is the jelly-like, innermost layer of each tooth. It contains nerves and blood vessels. It is what keeps the tooth alive. Cavities, cracks, and other traumas can expose tooth pulp. Exposed pulp makes the tooth vulnerable to infection. Left untreated, this infection can spread to other areas of the mouth and body.
While research into inflammation initially focused on acute responses, the focus has shifted to chronic inflammation, particularly in relation to systemic diseases. Innate immunity offers immediate defense against pathogens through general mechanisms, serving as the body's first line of defense. Adaptive immunity allows the body to recognize specific pathogens and develop a tailored response through antibody production and the activation of specific immune cells. These cells interact closely with tissue-specific cells — odontoblasts and fibroblasts — to mount a targeted immune response.
Once bacteria invade the pulp, the body reacts with inflammation — leading to swelling, pain, and, if untreated, pulp death.
Evidence of systemic involvement — such as a fever higher than 38.5 °C, cervical lymphadenopathy, or malaise — indicates antibiotic therapy, as do rapidly spreading infections, cellulitis, or severe pericoronitis. Left untreated, an exposed tooth pulp can lead to life-threatening conditions, including oral sepsis, brain abscess, meningitis, purulent sinusitis, orbital cellulitis, and cavernous sinus thrombosis.
Most toothaches are a result of a cavity. Sugar and starch in foods are the substances that cause damage to teeth. The bacteria in the mouth feed on sugar and starch and produce an acid that can eat through the teeth, leading to tooth decay. Different types of bacteria are involved in this process that can lead to an infection in the inside of the tooth.
Global shifts toward Westernized eating habits — characterized by high intakes of sugars, refined carbohydrates, saturated fats, and ultra-processed foods — have contributed to rising rates of dental caries, gingivitis, and periodontitis.
Periodontal disease is a chronic inflammatory condition influenced by both local and systemic factors. Nutritional exposures have been implicated in modulating inflammatory responses relevant to periodontal tissue breakdown, positioning diet as a potential modifier of disease susceptibility and progression.
The most significant effect of nutrition on teeth is the local action of diet in the mouth on the development of dental caries and enamel erosion. Dental erosion is increasing and is associated with dietary acids. Extrinsic factors include demineralizing acidic foods — such as citrus fruits and acidic beverages — and some medicines such as effervescent vitamin C preparations. Intrinsic causes of erosion include recurrent vomiting as a result of psychological disorders such as anorexia and bulimia. One important additional factor in dental erosion is low salivary flow, which results in inadequate rinsing and buffering of demineralizing acids on tooth surfaces.
The presence of xerostomia with a low or altered salivary flow may place patients at a higher risk of dental caries, gingivitis, erosion and ulceration of mucosal tissues, oral candidiasis, dysgeusia, and dysphagia. Other possible causes of dry mouth include uncontrolled diabetes, chronic graft-versus-host disease, Sjögren's syndrome, vasculitis, dehydration, malnutrition, psychogenic conditions, and immunodeficiencies.
In a cross-sectional study, elderly people with diabetes had significantly higher odds of having self-reported xerostomia (OR: 3.59; 95% CI: 1.48–8.68; p < 0.001).
Nutrition affects the teeth during development and malnutrition may exacerbate periodontal and oral infectious diseases. Vitamin A deficiency leads to impaired epithelial tissue development, tooth formation, and enamel hypoplasia. Vitamin D and calcium deficiency cause hypo-mineralization, delayed eruption, the absence of lamina dura, and abnormal alveolar bone patterns.
Delayed tooth eruption and salivary gland dysfunction may be linked to protein deficiencies.
Dietary free sugars are the most important risk factor for dental caries. Dental caries affects up to 80% of the world's population with almost a quarter of US adults having untreated caries. Dental caries is costly to health care and negatively affects well-being.
The WHO recommends limiting the intake of free sugars to less than 10% of total energy intake — and ideally to less than 5% — to minimize the risk of dental caries throughout the life course. Frequent sugar consumption and fermentable carbohydrates promote acidogenic shifts in the oral biofilm, driving demineralization and caries development, while nutrient-poor, pro-inflammatory diets amplify gingival and periodontal inflammation.
Frequent consumption of simple carbohydrates, primarily in the form of dietary sugars, is significantly associated with increased dental caries risk. The risk of caries increases with more frequent and higher free sugar intake and consumption of food with a tendency to be retained in the oral tissues for longer. Free sugar intake between meals is also associated with higher caries rates.
Dental erosion is increasing and is associated with dietary acids, a major source of which is soft drinks. There is growing evidence of a considerable increase in consumption of potentially erosive drinks. There have been significant associations shown between soft drink consumption and dental erosion.
A study found that the timing of fruit intake was crucial in tooth wear progression, with a significantly increased odds ratio (3.64) for fruit intake between meals when compared to fruit intake with meals. Of all supplements, chewable vitamin C (ascorbic acid) tablets increased the risk of dental erosion at an odds ratio of 1.16.
Studies have shown that populations that consume diets rich in antioxidants such as vitamins A, C, and E, fruits, vegetables, and omega-3 fatty acids demonstrate lower risks of developing periodontal disease. Diet is a key determinant of oral and periodontal health, influencing inflammation, oxidative stress, salivary composition, and the oral microbiome.
Findings from animal and human studies suggest that adherence to a diet high in calcium, phosphorus, fat-soluble vitamins A and D, and antioxidant vitamin C, as well as low in phytates, may contribute to arrest and reversal of dental caries. Furthermore, findings from observational and experimental studies suggest that fat-soluble vitamins A, D, and K2 may interact to protect against dental caries progression, even within a diet that regularly contains sugar.
Among contributing factors, vitamin D deficiency has been increasingly recognized as a major risk factor for the development of dental caries. Research has shown that children who experience vitamin D deficiency, particularly during the development of both primary and permanent teeth, have a higher likelihood of developing dental caries compared to their peers with sufficient vitamin D levels. This association is thought to be linked to the role of vitamin D in calcium metabolism and its influence on the formation of tooth enamel.
This relationship is attributed to vitamin D's influence on enamel formation, its role in enhancing antimicrobial peptide production, and its contribution to salivary gland function, which collectively help reduce bacterial load and acid production in the oral cavity.
The analysis of selected articles shows that vitamin D deficiency can lead to various oral health disorders during growth and adulthood. It can be linked to tooth mineralization defects and increasing the risk of dental caries. Severe vitamin D deficiency also increases the prevalence of periodontitis and gingival inflammation.
Vitamin D is essential for calcium homeostasis, bone remodeling, and immune function. It modulates both innate and adaptive immune responses, enhancing antimicrobial peptide production and reducing inflammatory cytokine expression.
Evidence level: Although these bioactive compounds show promising effects in preclinical and clinical studies, significant knowledge gaps remain regarding optimal dosages, long-term efficacy, combined use, and standardized treatment protocols.
Findings from one population-based study suggest a protective association between dietary calcium intake and periodontitis among women. Inadequate calcium and magnesium levels have been associated with severe periodontal disease.
In a study of 145 healthy subjects aged 65 years and older who completed a 3-year, randomized, placebo-controlled trial, tooth loss was examined at 18 months and 5 years. A comprehensive oral examination at 5 years included assessment of caries, oral hygiene, and periodontal disease. This study found a link between vitamin D and calcium intake to prevent osteoporosis and tooth loss risk.
Antioxidants such as vitamin C help alleviate inflammation in periodontal tissues. Vitamin C, a crucial dietary antioxidant, plays a vital role in maintaining connective tissue integrity and modulating immune responses, making it beneficial for periodontal health.
The appropriate supplementation of vitamin C may lead to lower levels of inflammation owing to its antioxidant properties. If used in conjunction with non-surgical periodontal therapy, it may lead to better treatment outcomes.
Evidence level: Evidence is primarily observational and from small clinical studies. Larger RCTs are needed to confirm supplemental vitamin C as a meaningful therapeutic adjunct in dental pain contexts.
Omega-3 fatty acids reduce the production of pro-inflammatory eicosanoids while promoting the synthesis of pro-resolving lipid mediators, contributing to bone preservation and immune balance. Omega-3 fatty acids are well-known for their anti-inflammatory effects, which help reduce periodontal inflammation.
Evidence level: A meta-analysis pooled analysis revealed a significant overall periodontal pocket depth reduction (MD 1.73 mm, 95% CI [0.75, 2.71]; p = 0.0005), though with substantial heterogeneity (I² = 97%). Findings suggest that omega-3 fatty acids demonstrate clinically meaningful improvements, though other interventions show more variable effects. Evidence remains preliminary for direct application to toothache pain relief specifically.
Clove powder (Syzygium aromaticum) has long been utilized as a natural toothache treatment in traditional Indian medicine. Eugenol, a bioactive substance with analgesic, anti-inflammatory, and antibacterial qualities, is principally responsible for its efficacy. Clove has been used in Ayurvedic and Unani systems, and clove oil was also used in early dental anesthetic preparations in European herbal traditions. Eugenol has been in use in dentistry since the 19th century.
Eugenol is the major constituent (70% to 90%) in the aromatic oil extract from cloves (Syzygium aromaticum), a spice widely used as a flavoring for meats, stews, cakes, and teas. In vitro, eugenol has been shown to have antibacterial, antifungal, antioxidant, and antineoplastic activity. Clove oils including eugenol have been claimed to have gentle local anesthetic and antiseptic activities and previously were commonly used in dentistry.
A 2006 trial of 73 adults found that the use of clove oil was as effective as benzocaine, a topical anesthetic. Both worked significantly better than a placebo.
The mechanism involved in the analgesic activity of eugenol is the activation of calcium and chloride channels in ganglionar cells. The analgesic effect of eugenol is also due to its ability to inhibit prostaglandins and other inflammatory mediators.
Eugenol was consistently effective across oral surgery and endodontic pain, with moderate-certainty evidence.
Evidence level: A 2017 systematic review published in the Journal of Dentistry analyzed available evidence on the use of clove oil for dental pain relief. The review concluded that while clove oil may provide temporary relief from toothache pain, more high-quality research is needed to determine its effectiveness compared to conventional treatments. Overall, eugenol holds the strongest evidence base among phytotherapeutics for dental pain.
Turmeric has been used in Ayurvedic and traditional Asian medicine for centuries as an antiseptic and anti-inflammatory agent applied to wounds, gums, and oral tissues. Turmeric is also used in medicine as an antiseptic, anti-inflammatory, antioxidant, and for wound healing.
Reviewed studies demonstrated that curcumin and chlorhexidine had similar efficacy for decreasing plaque and gingival indices. Curcumin and chlorhexidine have comparable anti-plaque and anti-inflammatory properties in gingivitis, with fewer side effects noted for curcumin when compared to chlorhexidine.
Curcumin was tested in several studies with variable outcomes; some trials showed equivalence to mefenamic acid, while others reported limited benefit depending on formulation.
Evidence level: Curcumin showed variable outcomes influenced by formulation and bioavailability, with low-certainty evidence. Current evidence is preliminary, and the poor bioavailability of curcumin in standard formulations is a recognized limitation.
Ginger root has been used in traditional Chinese, Ayurvedic, and Middle Eastern medicine as an analgesic and anti-inflammatory agent, including topical application to painful teeth and gums.
Ginger showed consistent analgesic effects, comparable to ibuprofen, in both postsurgical and periodontal pain management.
Evidence level: Ginger is comparable to ibuprofen for postsurgical and periodontal pain, with moderate-certainty evidence. This is among the more robust findings for herbal agents in dental pain contexts, though study numbers remain limited and larger RCTs are needed.
Propolis, a resinous material collected by bees from plant sources, has been used in folk medicine across Europe, Asia, and the Americas for its antimicrobial and wound-healing properties, including application to painful teeth and infected gums.
Studies demonstrated enhancements in oral hygiene, evidenced by decreased oral hygiene index scores and reduction in the gingival bleeding index. This outcome is ascribed to the antibacterial properties of propolis against oral infections, aiding in the reduction of plaque buildup and inflammation.
Evidence level: Propolis, Punica granatum, and green tea extract demonstrated limited evidence in the systematic review applying GRADE methodology. Evidence is preliminary and largely derived from small trials.
Capsaicin from chili peppers (Capsicum spp.) has been used in folk traditions in Central and South America and in Ayurvedic medicine for topical pain relief, including dental and oral pain.
Phytotherapeutic agents demonstrating analgesic properties in dental applications include capsaicin from chili peppers. Mechanisms of action range from inhibition of prostaglandin synthesis to modulation of inflammatory pathways and direct effects on nociceptors.
Evidence supports the analgesic efficacy of capsaicin in toothache management, though standardization of preparations and larger RCTs are needed to establish optimal dosing regimens and long-term safety profiles.
Evidence level: Preliminary, largely from laboratory and small clinical studies. Long-term safety and optimal dosing are not established.
Green tea has been used in East Asian traditional medicine — particularly in China and Japan — as an oral rinse and systemic anti-inflammatory agent, with historical application to gum and tooth complaints.
Consuming a nutrient-rich diet abundant in antioxidants and anti-inflammatory compounds has been strongly linked to a reduced likelihood of developing periodontitis and a slower progression of the disease. Green tea polyphenols (catechins) are among the antioxidant compounds studied in periodontal contexts. Green tea extract demonstrated limited evidence in the most recent systematic review of phytotherapeutic agents for dental pain management using GRADE methodology.
Evidence level: Weak; further high-quality clinical trials specific to dental pain are lacking.
Cannabis derivatives have been used across various historical traditions for pain relief, and cannabidiol (CBD) — a non-psychoactive component of Cannabis sativa — has been investigated for dental pain in contemporary studies.
CBD demonstrated dose-dependent pain reduction in temporomandibular disorders and emergency toothache, with low-to-moderate certainty of evidence. Cannabis-derived cannabidiol (CBD) demonstrated significant pain reduction in temporomandibular disorders and emergency toothache, with dose-dependent effects.
Evidence level: Low-to-moderate certainty, based on a limited number of RCTs. Research in this area is emerging and regulatory status varies widely by jurisdiction.
Evidence supports the analgesic efficacy of several phytotherapeutic agents in toothache management, particularly eugenol, curcumin, and capsaicin. These offer promising alternatives or adjuncts to conventional analgesics, though standardization of preparations and larger RCTs are needed to establish optimal dosing regimens and long-term safety profiles.
The consumption of free sugars in foods and beverages is the most common risk factor for dental caries. Available data clearly show that people already consume significantly more sugar than they should, increasing the risk for dental caries, overweight, and obesity.
Dietary patterns that minimize prolonged exposure of teeth to acid — by reducing the frequency of acidic beverage consumption and consuming acidic foods at mealtimes rather than between meals — are consistently recommended across the literature. A study found that timing of fruit intake was crucial in tooth wear progression, with a significantly increased odds ratio for fruit intake between meals. Older adults can be advised about the proper dietary fruit intake habits to avoid tooth wear progression.
Higher consumption of fruits, vegetables, omega-3 fatty acids, and vitamins A, C, and E has been linked to improved population health in terms of periodontal tissue. Adequate intake of essential minerals and vitamins is required for maintaining periodontal health. Vitamins K, D, and A are crucial in maintaining oral epithelial integrity, facilitating bone development, and supporting overall tissue maintenance.
One important factor in dental erosion is low salivary flow, which results in inadequate rinsing and buffering of demineralizing acids on tooth surfaces. Adequate hydration supports salivary flow, which serves as a physiological buffer against the acids produced by cariogenic bacteria.
The literature shows that diet and nutrition are related to oral diseases, including dental caries, periodontal diseases, tooth wear, and even oral cancer. Insufficient nutritional intake and poor dietary habits increase the risk of oral diseases.
Protecting oral health into old age is important because poor oral health in later life negatively affects quality of life and is associated with malnutrition and hospitalization.
Thymol from ajwain is an established dental antiseptic and analgesic. A 2025 clinical RCT (n=52 children) demonstrated ajwain oil's superior pain-reducing effect vs. lidocaine spray for dental injection pain. Multiple in vitro studies confirm activity against oral bacteria. This constitutes direct human clinical evidence.
Eugenol—the principal constituent of allspice oil (up to ~90%)—has an established scientific basis for dental analgesia. It is FDA-recognized for temporary toothache relief and widely used in dentistry. Allspice itself shares this bioactive but has less concentrated eugenol than cloves and lacks its own clinical trials.
Propolis is a bee-derived resin with flavonoids that inhibit COX and LOX enzymes, reducing pulpal inflammation. A 2024 PMC narrative review of 104 studies (53 human clinical trials) confirmed propolis's antimicrobial activity against oral pathogens, anti-inflammatory effects, and utility in endodontic procedures. A 2025 PMC systematic review of 21 dental pain studies ranked propolis among the strongest phytotherapeutic analgesics for dental applications.
Capsaicin acts on TRPV1 receptors, initially activating then desensitizing nociceptive neurons, leading to pain relief.

A 2025 PMC systematic review ranked capsaicin among the top phytotherapeutic analgesics for dental pain alongside eugenol and curcumin. FDA recognizes capsaicin as a counter-irritant in OTC topical analgesic products.
Capsicum (chili pepper plant) is the source of capsaicin and capsaicinoids, which act on TRPV1 receptors to desensitize dental nociceptors. A 2025 PMC systematic review of 21 dental pain studies confirmed capsaicin from chili peppers (capsicum) as one of the top analgesic phytotherapeutic agents for dental pain. It has been used since ancient times as a traditional remedy for toothache across Mesoamerican cultures.
Carvacrol is a phenolic monoterpene found in thyme, oregano, and other plants with established antibacterial and anti-inflammatory activity against oral pathogens. In vitro studies confirm its inhibition of Streptococcus mutans and periodontal bacteria. It contributes to the dental analgesic efficacy of carvacrol-rich essential oils used in toothache formulations and has been incorporated into patent-protected oral health compositions.
Clove (Syzygium aromaticum) contains eugenol (70–90% of its oil), a clinically recognized local anesthetic and antiseptic used in dentistry since the 19th century. A 2006 Journal of Dentistry study found clove gel equivalent to benzocaine for pre-injection topical anesthesia. A PMC 2025 systematic review of 21 clinical studies ranked eugenol among the strongest phytotherapeutic analgesics for dental pain. Eugenol inhibits voltage-gated sodium channels and prostaglandin synthesis, providing temporary pain relief and reducing pulpal inflammation.
Curcumin, the active polyphenol in turmeric, inhibits NF-κB and COX-2 pathways, reducing pulpal inflammation. A 2013 PMC review documented traditional use for dental pain and confirmed its anti-inflammatory, antimicrobial, and antiseptic properties for oral applications. A 2025 PMC systematic review ranked curcumin among the top three phytotherapeutic analgesics for dental pain. Clinical studies show curcumin gel as an adjunct for periodontal and pulpal pain management.
Eugenol is the primary bioactive constituent of clove oil and a foundational compound in professional dental analgesia. It inhibits voltage-gated sodium channels and prostaglandin synthesis, providing direct local anesthesia to dental pulp nociceptors. A landmark 2006 RCT demonstrated equivalence to benzocaine 20% for topical pre-injection anesthesia. It remains a standard ingredient in dental cements and root canal medicaments used clinically for toothache and pulpitis.
Garlic releases allicin when crushed, a compound with antibacterial activity against key oral pathogens including Streptococcus mutans and periodontal bacteria. A PubMed-indexed 2011 in vitro study found allicin inhibited all tested oral pathogenic bacteria at concentrations of 300–2400 µg/mL. A small clinical study of 24 participants found garlic paste applied for five days relieved dental pain more effectively than ibuprofen alone. Traditional use for toothache spans multiple centuries across Asian, Middle Eastern, and European folk medicine.
Ginger (Zingiber officinale) contains gingerols and shogaols that inhibit prostaglandin synthesis, producing anti-inflammatory and analgesic effects. A 2025 PMC systematic review of 21 dental pain clinical studies found ginger powder achieved pain control equivalent to conventional NSAIDs post-dental surgery. The review ranked ginger among only two phytotherapeutics (alongside eugenol) with the most consistent evidence for dental analgesia.
Myrrh possesses documented local anesthetic and analgesic properties attributed to furanosesquiterpenes that act on mammalian nerve cells. It has been used as a topical analgesic applied directly to the gums. Laboratory studies confirm local anesthetic activity in nerve cell preparations.
Peppermint contains menthol, which desensitizes nerve endings and provides a cooling analgesic effect on dental pain. A 2013 study confirmed peppermint oil's antibacterial activity against Streptococcus mutans, an oral cariogenic pathogen linked to toothache. Menthol is an active ingredient in several OTC oral care products (e.g., Orajel). Traditional use for toothache relief spans multiple centuries of Western and Asian herbal medicine.
Thymol, an active phenol in thyme oil, is an established dental antiseptic and analgesic used in oral care products for over a century. It inhibits the growth of Streptococcus mutans and other oral pathogens. Thymol is a key ingredient in commercial mouthwashes (e.g., Listerine) and is documented in dental literature as effective against caries-causing bacteria and oral infections contributing to toothache.
Spilanthes (Acmella oleracea/Spilanthes acmella), commonly called the Toothache Plant, has earned its name from long-established traditional and pharmacological use for dental pain relief. Its active compounds spilanthol and acmellonate act as local anesthetics, producing numbing, tingling, and analgesia when the plant flowers are chewed. A 2013 PMC phytochemistry review confirmed its local anesthetic, antinociceptive, and antimicrobial activities in multiple experimental models.
Turmeric (Curcuma longa) contains curcumin, a well-documented COX-2 and NF-κB inhibitor used in Ayurvedic medicine for centuries to relieve dental pain. A 2013 PMC review confirmed massaging aching teeth with roasted ground turmeric as a documented traditional practice supported by anti-inflammatory and antiseptic evidence. A 2025 systematic review ranked turmeric (curcumin) among the top phytotherapeutic analgesics for dental pain in 21 clinical studies.
Zanthoxylum species—particularly Z. armatum—are known as 'toothache trees,' and their use for toothache relief is one of the most consistent and cross-culturally documented applications, with supporting antimicrobial and local anesthetic preclinical data. Z. armatum fruits demonstrated MIC activity against oral pathogens. The numbing (sanshoamide) compounds provide a local anesthetic mechanism.
Baobab seed oil has been traditionally used to treat inflamed gums and diseased teeth across Africa.
