Prophylaxis removes plaque and tartar from the teeth (not the roots – see root planning). This will make the gums and teeth healthier. It is not uncommon for patients to note that teeth appear slightly more sensitive after a dental cleaning. The reason for this is that plaque and tartar coat the tooth surface and shield them from substances in the mouth. It is important for one to brush and floss after every meal to prevent buildup of plaque and tartar.
