Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Vitamin A is primarily recognized for its role in vision, immune function, and maintaining epithelial tissues, including the mucous membranes in the mouth. There is scientific evidence indicating that vitamin A is important for the maintenance and repair of the soft tissues in the oral cavity, such as gums and mucous membranes. Deficiency in vitamin A can lead to keratinization and degeneration of these tissues, which may indirectly affect oral health and the environment surrounding the teeth. However, vitamin A does not play a direct role in the formation or mineralization of hard dental tissues like enamel or dentin, which are more dependent on nutrients such as calcium, phosphorus, and vitamin D. Some studies have shown that adequate vitamin A status supports the health of oral soft tissues and can help prevent conditions like oral leukoplakia and periodontal disease. Nevertheless, the evidence linking vitamin A specifically to the structural health of teeth is limited and not as robust as for other nutrients. Therefore, while vitamin A is scientifically validated for supporting the broader oral cavity, its direct impact on the teeth themselves is less clear, resulting in a moderate evidence rating.
