​​​​​​How can diabetes affect my teeth and gums?

Diabetes can cause problems such as:

  • gum disease
  • dry mouth which can lead to tooth decay
  • infections that make it harder to manage diabetes.

Teeth and gum problems you might see:

  • red, swollen or bleeding gums
  • loose teeth
  • bad breath
  • sensitive teeth
  • change in taste
  • white patches in your mouth.

What can I do to prevent teeth and gum problems?

  • Brush your teeth 2 times a day with fluoride toothpaste.
  • Clean between your teeth with dental floss or an interdental brush.
  • Clean your dentures daily and take them out at night and leave dry.
  • See a dentist at least once a year.
  • Keep your blood sugar levels under control.
  • After a hypoglycemic episode, avoid brushing your teeth immediately, instead, rinse your mouth with water.

What are my healthy choices?

  • Choose water as your everyday drink.
  • Eat regular meals, spreading them evenly throughout the day.
  • Each day, aim to eat 2 serves of fruit, and add vegetables to 2 meals.
  • Limit foods and drinks high in energy – sugary drinks, lollies, chocolate, muffins, cakes, chips.
  • If you choose to drink alcohol, limit intake to no more than 2 standard drinks per day.
  • Do not smoke - if you do, try and quit.  Call Quitline 137 848 for support.
  • Adults should be physically active most days, preferably every day.

Everyone’s needs are different so please see your doctor, diabetes educator or dietitian for advice and ask about any Medicare benefits for this.
