What are mouth sores?
Mouth sores are small cuts or ulcers in the mouth. The sores may be bright red in color or have small white patches. Mouth sores may be painful.

What can I do?
- Check your entire mouth daily (lips, gums, tongue, roof of mouth and inside of cheeks) using good lighting and a mirror. If you wear dentures, remove them and look under the plates.
- Brush your teeth after eating or at bedtime:
- Gently brush the teeth with a soft nylon bristle toothbrush. If this is painful, use foam toothettes or wrap gauze around a PopsicleÂ® stick. Gently swab the teeth and gums.
