Thanks to vitamin A, your body can absorb calcium and protein, as well as keep the mucous membranes healthy. This is important because the mucous membrane (the tissue lining the cavities) helps protect your teeth and gums. At the same time, vitamin A is also an important source to prevent dry mouth and improve your oral health.
Foods that are high in vitamin A: Orange and red foods will contain adequate amounts of vitamin A such as carrots, oranges, pumpkins, cantaloupe, tomatoes, apricots, and sweet potatoes. Also, other foods like egg yolks, spinach, collard greens, and kale are high in vitamin A. Since all of these foods contain high levels of beta-carotene, your body will convert them to vitamin A easily.
