What are canker sores? These are painful sores that may appear on the tongue, palate, gums, or the inside of the lips or cheeks. When the top layer of the mucosa is removed, the nerve endings are exposed. Food, drink, air and saliva can then irritate these nerve endings, causing even more pain and slowing the healing process. Therefore, canker sores can affect the ability to concentrate, eat, drink and even speak normally. The good news is that we have a solution.
