Vitamin D Supplementation
Some people have easily damaged teeth because of their inability to absorb and use calcium in their bones and teeth. They may regularly consume calcium-rich foods, but they still fail to get the benefits of calcium intake. One of the common reasons for this is vitamin D deficiency.
The United States NIH Osteoporosis and Related Bone Diseases National Resource Center says that vitamin D is important in immune function. It also facilitates better calcium use in the body, which is crucial for those who tend to be predisposed to dental cavity formation. When the body fails to absorb enough calcium from food, it naturally cannibalizes other body parts with calcium stores, the bones, and teeth in particular.
Those whose teeth easily break or develop cavities should consider having themselves tested for possible vitamin D deficiency. A 25-hydroxy vitamin D blood test is usually undertaken for this.
Vitamin D is naturally produced by getting exposed to sunlight. It may also be obtained by consuming vitamin D-rich food such as egg yolks, liver, saltwater fish, and fortified milk. Adults require an intake of 600 to 800 IU of vitamin D daily.
