Rating (out of 5): 3

Magnesium plays a scientifically validated role in supporting dental and oral health, although it is not as widely discussed as calcium or vitamin D. Magnesium is essential for the structural development of bones and teeth. Approximately 60% of the body's magnesium is found in bone, including teeth, where it contributes to enamel and dentin formation. Several studies suggest that magnesium deficiency can be associated with increased risk of periodontal disease, tooth decay, and weakened tooth structure. Magnesium is involved in the regulation of calcium and phosphate balance, both of which are crucial for healthy tooth mineralization. Furthermore, magnesium helps maintain the integrity of tooth enamel by influencing crystal formation and preventing demineralization.

Scientific evidence includes epidemiological studies linking low dietary magnesium intake with poor periodontal health. Some research has shown that adequate magnesium levels correlate with lower incidence of tooth loss in older adults. However, most of the evidence is observational, and direct interventional studies examining magnesium supplementation and dental outcomes are limited. While magnesium alone is not a cure-all for dental disease, ensuring sufficient intake is considered a component of comprehensive oral health, particularly because of its synergistic relationship with other minerals.

Overall, the use of magnesium to support dental health is justified by scientific understanding of its physiological roles, though the direct clinical impact of supplementation in populations with adequate intake remains to be fully clarified.
