Mouth

FLOOR AND ROOF OF MOUTH Tilt back your head and open your mouth wide to inspect the roof of your mouth. Look to see if there are changes in colour or ulcers. Check for changes in texture with your finger. Lift your tongue up and look underneath at the floor of your mouth. Look for any colour changes that are unusual. Gently press your finger along the floor of your mouth and under your tongue. Feel for any lumps, swellings or ulcers.
