Home remedies for mouth ulcer on lip

A small lip ulcer can often be soothed by avoiding irritants, rinsing gently with salt water, and choosing cool, soft foods while it heals.

An ulcer on the inner lip is a break in the mouth lining, often caused by biting, a sharp tooth, friction, hot food, irritation, stress, or an underlying illness.

Rinse with mild salt water, keep brushing with a soft brush, and avoid spicy, acidic, rough, or very hot foods. A pharmacist or dentist can advise on a topical protective or pain-relieving product suited to your health conditions.

Arrange an examination if the sore is unusually large, recurrent, spreading, associated with fever or difficulty swallowing, or does not heal.

Ask whether a sharp tooth, filling, appliance, medication, nutritional problem, or recurrent condition could explain it and which treatment is appropriate.
