What Are Mouth Lesions?
By Brian Joseph MillerMedically Reviewed by Sanjai Sinha, MD
Sores on your mouth, lips, tongue and inner cheek are often caused by viral infections or minor injury.
Mouth lesions and sores rarely require immediate emergency medical attention, but they can be painful and embarrassing, especially if the sores are visible. A person with a mouth or tongue lesion has lumps, bumps, little ulcers, or cuts or sores inside or outside the mouth and lips.
The first thing to do if you have a painful mouth is to identify the source because there are many different kinds of mouth sores. Open your mouth and take a look inside, preferably in bright light with a magnifying mirror.
