Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Tea Tree Oil (Melaleuca alternifolia) has been investigated for its antimicrobial properties, particularly in oral health contexts. Several in vitro studies have demonstrated that tea tree oil exhibits antibacterial activity against oral pathogens such as Streptococcus mutans and Porphyromonas gingivalis, which are associated with dental caries and periodontal disease, respectively. Small clinical studies have explored its use in mouthwashes or gels, reporting reductions in plaque accumulation, gingival inflammation, and bleeding when compared to placebo. For example, a randomized controlled trial published in the journal Australian Dental Journal (2004) found that a tea tree oil gel reduced gingivitis scores compared to a placebo over four weeks.

However, the sample sizes in these studies are often modest, and the duration is typically short. Tea tree oil is not widely used in mainstream dental practice, partly due to concerns about taste, potential toxicity if swallowed, and risk of allergic reactions. Major dental organizations have not endorsed its routine use, and more robust, long-term clinical trials are needed to confirm its efficacy and safety for oral health. Nonetheless, the body of preliminary scientific evidence does indicate some potential benefits for supporting the health of the teeth and gums, justifying a moderate evidence rating.
