22. Falling low on both calcium and vitamin D
In order to prevent bone loss and strengthen your teeth, your body needs both calcium and vitamin D. According to Townsend, calcium is an essential mineral in the formation of jaw bone and teeth. Therefore, a calcium deficiency could lead to gum disease and tooth decay.
Along with calcium, your teeth need vitamin D too. This vitamin helps your body absorb the calcium it needs in order to minimize the risk of developing cavities and other dental issues. On top of that, it also helps lower the bone resorption rate.
Numerous studies have shown that vitamin D can decrease the chances of developing periodontal disease. Consider adding more calcium and vitamin D sources in your diet, such as cheese, tuna, salmon, eggs, milk, broccoli, kale, Collard greens, and nuts.
