Canker sores are small, painful ulcers on the inside of the mouth, tongue, lips, or throat.
The main symptom of a canker sore is getting a shallow ulcer on your tongue or on the inside of your lip or cheek. The sore may be large or small, and it will have a red border and a white or yellow center. You might have more than one canker sore at a time.
Canker sores usually begin with a burning or tingling feeling. They may be swollen and painful. Having a canker sore can make it hard to talk or eat.

3. Also, practice good oral health and use a soft toothbrush to avoid irritating your gums and soft tissue. Consult with your doctor to determine if you suffer from any specific vitamin and/or mineral deficiencies.
