Diabetes and oral health

There is a two-way relationship between diabetes and oral health. Maintaining good oral health is an important part of managing diabetes. Keeping blood sugars within target levels is important for a healthy mouth. Having diabetes does not mean you will have worse oral health. It depends on how well you manage your blood sugar levels.

Oral health issues linked with diabetes

  • High blood sugar can lead to:
    • Gum disease. (please note untreated gum disease can also lead to high blood sugar levels)
    • Slow healing after extractions or oral surgery
    • Oral infections including fungal infections such as thrush
    • Dry mouth and taste impairment. Some diabetes medications can cause dry mouth too.
  • People with diabetes are at greater risk of oral cancer and may not respond well to oral cancer treatments.

Tell your oral health professional

  • if you have diabetes
  • if you have trouble keeping your blood sugar levels under control
  • if you notice changes in your mouth, such as sores or patches of red or white skin
  • if there have been any changes to your medical history
  • the names of all medications you are taking, including prescription and over-the-counter drugs
  • if you smoke. People who smoke have poorer blood circulation in the gums. This increases the risk of gum disease.

How you can improve your oral health

  • See your GP or diabetes team if you are having trouble controlling your blood sugar levels
  • Seek help to QUIT smoking - people with diabetes who smoke have a greater chance of severe gum disease than people with diabetes who don't smoke
  • Follow your healthy eating plan. Take prescribed medications as instructed by your doctor
  • Check the insides of your mouth regularly for:
    • Signs of gum disease, such as swollen red gums that bleed easily when touched or brushed
    • Sores, ulcers or unusual looking white or red patches. You should see your oral health professional straight away if any of these do not go away after 2 weeks
  • Brush your teeth twice a day with fluoride toothpaste and a soft toothbrush. Clean between teeth every day using dental floss and/or interdental brushes.
  • Keep a good denture care routine
  • Visit your oral health professional regularly, for people taking insulin, consider morning appointments. Blood sugars levels may be easier to control in the morning.
