When to seek medical advice

Many of the common symptoms can be caused by less serious conditions, such as an infection.

However, it's strongly recommended that you see a GP or dentist if any of the symptoms have lasted longer than 3 weeks. It's particularly important to seek medical advice if you drink or smoke regularly.

Dental check-ups

Mouth cancer often does not cause any noticeable symptoms during its initial stage.

This is why it's important to have regular dental check-ups, particularly if you smoke, drink heavily, chew tobacco or chew betel nut (a type of nut commonly consumed in Asia). Your dentist may be able to detect mouth cancer during your examination.

You should have a dental check-up at least once every year. More frequent check-ups may be recommended if you have a history of tooth decay or gum disease.
