What mouth problems should I look out for?

- Swelling or infection

What should I know about mouth cancer?

Mouth cancer can develop on the tongue, tonsils, lips or other parts of the mouth.
Smoking or using tobacco can increase your risk.
Drinking a lot of alcohol can also increase your risk.
Using tobacco and drinking alcohol together increases the risk further.
Get medical or dental advice if you notice:
- An ulcer that does not go away within 2 to 3 weeks.
- A white or red patch in your mouth.
- An unusual lump or swelling in your mouth or throat.
How can smoking and alcohol affect my mouth?
- Smoking can cause bad breath, stained teeth, gum disease, a dry mouth and changes in taste.
- Alcoholic drinks can contain a lot of sugar and acid.
- Acid can wear away enamel, the hard outer layer of your teeth.
How can substance use affect my mouth?
- You may want more sugary food.
- Your mouth may become dry, which can increase the risk of dental problems.
- Clenching or grinding your teeth can cause cracked teeth, jaw pain and headaches.
- It may become harder to keep up regular toothbrushing.
- If you have been prescribed methadone and are not sure whether it is sugar-free, ask your health professional about a sugar-free option.
How can I look after my mouth?

- Brush your teeth twice a day for 2 minutes with fluoride toothpaste.
- Brush once during the day and again last thing at night.
- After brushing, spit out the toothpaste but do not rinse with water.
- Cut down on sugary food and drinks, including alcohol.
- See a dentist regularly, even if you have only a few teeth or no natural teeth.
