Diabetes (diabetes mellitus) does increase the chance of dental problems, including tooth decay, dry mouth, fungal infections (thrush) and gum disease. You can prevent dental problems by keeping your blood glucose well-managed. Check your blood sugar regularly and write down the number. Show your doctor the numbers at your next visit to make sure you are within safe limits. Also, eat a balanced diet. Lose weight if you are overweight. Exercise regularly, at least 30 minutes most days. Stop cigarette smoking, if you smoke. If you take diabetes pills, make sure you are compliant to your medication. If you need guidance in managing your blood sugar, talk to a diabetes educator. If you want additional information on dental problems with diabetes, make an appointment to see your dentist soon.
