HEALTH INFORMATION

Have you ever had a canker sore? If so, you know that these small mouth sores can cause major pain. You can get a canker sore on the inside of your lip or cheek, or on your tongue or the roof of your mouth. Usually canker sores form one at a time inside your mouth, but you can get more than one in a little cluster.
Canker sores are round and usually about the size of a kernel of corn (1/4 inch, or 6 millimeters), but they can be as big as a quarter (1 inch, or 25 millimeters). If you look in the mirror at your canker sore, it will be white or yellow with a red border.
What Do Canker Sores Feel Like?
Canker sores hurt, especially if you eat something hard, crunchy, salty, or acidic (like orange juice). They usually go away on their own and they are not contagious. So no one can catch a canker sore by kissing you or sharing your drink.
