Synopsis

Source of validity: Scientific
Rating (out of 5): 4

Vitamin C (ascorbic acid) has strong scientific support for its role in maintaining oral and dental health. It is vital for the synthesis of collagen, a key structural protein in the gums and periodontal ligament. Deficiency in vitamin C leads to scurvy, which is characterized by swollen, bleeding gums, tooth mobility, and eventual tooth loss—demonstrating a direct link between vitamin C and oral tissue integrity. Numerous studies confirm that adequate vitamin C intake helps maintain healthy gum tissue, supports wound healing in the mouth, and may reduce the risk of periodontal disease. A 2019 review in the International Journal of Environmental Research and Public Health highlights the association between low vitamin C status and increased periodontal disease prevalence. While vitamin C does not directly impact tooth enamel or cavity formation, its role in gum health indirectly supports the stability and retention of teeth. Thus, the use of vitamin C to support dental and periodontal health is rooted in clear biochemical pathways and clinical evidence.
