Which vitamin deficiency is linked to enamel loss and increased risk of tooth decay?

Vitamin D plays a crucial role in dental health, particularly in maintaining the integrity of both teeth and bones. It facilitates the absorption of calcium and phosphate, which are essential minerals for the formation of strong enamel. Without adequate levels of vitamin D, the body cannot effectively regulate calcium, leading to a reduced capacity for enamel remineralization. This deficiency can result in compromised enamel strength, making teeth more susceptible to decay and erosion.

In addition to its role in tooth structure, vitamin D is also linked to overall oral health, influencing the immune system's ability to combat oral pathogens. Insufficient vitamin D levels can increase the risk of periodontal disease, further contributing to dental issues.

The other vitamins listed, while important for various bodily functions, do not have the same direct link to enamel health and tooth decay as vitamin D.
