A mouth ulcer is a small lesion which can develop on lips, tongue, gums, cheeks or on the roof of the mouth.

This is incredibly common, with almost everyone getting it at least once in life.

CAUSES

It is either caused by trauma to the mouth, or by a viral infection. However, this is non-contagious.

As ulcers often occur as a result of infection from plaque bacteria on the teeth, poor oral hygiene can also play a contributory role.

TREATMENT

Ulcers will disappear faster if they are not irritated or interfered with.

It, therefore, may be a good idea to avoid chewing on the side of the mouth where you have an ulcer.

You can use over-the-counter painkillers to reduce the discomfort caused by the ulcer. Anti-inflammatories fight infection as well as reduce pain.

Inflammation can also be reduced by rinsing the ulcer with warm salty water. Saltwater solution will also gently disinfect your mouth ulcer.

But if the ulcer is too painful and is unusually big, you should definitely see a doctor.

CANCER RISK

Mouth ulcers are usually benign, and are not a symptom of cancer.

However, those that do not go away can be a rare symptom of oral cancer.
