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