Vitamin D and Calcium are vital for maintaining optimal tooth health. Vitamin D facilitates calcium absorption, a key component for strong teeth. Lack of Vitamin D can reduce calcium absorption, contributing to gum disease, tooth decay, and potential tooth loss. Calcium, on the other hand, is essential for the strength and structure of teeth. Insufficient calcium in the body can weaken teeth, making them more prone to decay and breakage, ultimately resulting in tooth loss.
