How to reduce your risk of oral thrush

BMJ Group Medical Reference

There are things you can do to avoid getting oral thrush.

  • If you smoke, the best thing to do is to stop. You can have treatment to help you give up. To find out more, see our information on Smoking.

  • If you use a steroid inhaler to prevent asthma attacks, you can reduce your risk of getting oral thrush by rinsing your mouth out with water and brushing your teeth after using your inhaler. You can also use a device called a spacer to reduce the amount of steroid that stays in your mouth and throat. To find out more, see our information on asthma in adults or asthma in children.

  • If you wear dentures, make sure that they fit you properly. Your gums may shrink and the shape of your mouth may change as you get older, so your dentures stop fitting as well as they once did. You can have regular dental check-ups to make sure your dentures still fit you properly. Candida can grow on the surface of the dentures, so always keep your dentures clean, especially the surface that's in contact with the roof of your mouth. Leave your dentures out at night so that the lining of your mouth has a chance to recover.

  • If you have diabetes, your blood sugar needs to be kept under control to reduce your risk of oral thrush. This means testing your blood sugar levels and taking your diabetes medicine correctly. To find out more, see our article on Diabetes.

  • If you got oral thrush after taking antibiotics, be sure to tell your doctor if you need antibiotics again. Your doctor may be able to prescribe an antibiotic that is less likely to increase your risk of getting oral thrush.

  • If low iron or vitamin levels could be making you prone to mouth thrush, ask your doctor about changing what you eat or taking supplements.

  • Try to eat a balanced diet with plenty of fresh fruit and vegetables, and reduce the amount of refined carbohydrates that you eat, such as biscuits and sweets.
