Synopsis

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

Vitamin C (ascorbic acid and its mixed ascorbates) plays an established role in oral health, primarily through its function in collagen synthesis and maintenance of connective tissues, including the gums and periodontal ligament that support teeth. Scientific studies have shown that vitamin C deficiency can lead to scurvy, a condition marked by bleeding gums, tooth mobility, and even tooth loss due to impaired collagen formation and weakened capillaries. Observational studies have also found associations between low vitamin C intake and increased risk of periodontal disease, gingival bleeding, and slower wound healing following dental procedures. Furthermore, supplementation with vitamin C has shown some benefit in improving gum health and reducing inflammation in individuals with low baseline levels or gum disease.

However, while vitamin C is critical for maintaining the health of the supporting structures of teeth (gums, periodontal ligament), its direct effect on the hard tissues of teeth (enamel and dentin) is limited. There is little evidence that vitamin C supplementation prevents dental caries (cavities) or directly strengthens tooth enamel. The main support is via maintaining healthy gums and preventing periodontal disease, both essential for overall dental health.

In summary, there is scientific validation, particularly focused on supporting the gums and connective tissues around the teeth, rather than the mineralized tooth itself. Mixed ascorbates are simply buffered forms of vitamin C and function similarly in this context.
