Dental Health in Children with Diabetes

Published on: 08/10/2018

What is diabetes?

According to the NIH, diabetes is a disease in which blood glucose, or blood sugar, levels are too high due to a problem with insulin.

How does diabetes affect the oral health of children?

Children with diabetes can be more prone to soft tissue abnormalities.

Oral manifestations of diabetes

  • Periodontal disease (gums and bone around the teeth are affected)
  • Gingivitis
  • Reduced saliva
  • Taste dysfunction
  • Susceptible to fungal and bacterial infections

Dental Management and Prevention

Prevention is essential in managing the dental health of the child with diabetes. Scheduling the child for early professional dental examinations is recommended.

Tips for Proper Dental Hygiene

  • Avoid treatment during or at insulin peaks in order to reduce risk of hypoglycemia.
  • The child must eat normally and take medications as directed prior to appointment.
  • Apply topical fluoride and visit the dentist every 6 months.
  • Parents should begin brushing when the first baby tooth erupts and should assist their child in brushing until the child reaches 8 years of age.
  • Use fluoridated toothpaste; for children under 3 years old use a smear amount of fluoridated toothpaste and for children above 4 years old use a pea size amount.
  • Parents should monitor dietary practices (i.e. avoid prolonged use of bottle, reduce amounts of sugar consumed, reduce frequency of sugar consumed).

Preparing a child with Diabetes for a Dental Appointment

Discuss the medications currently being taken with the child's dentist. A thorough medical history and assessment of diabetes control should be completed by the dental provider. Morning appointments are advisable. Remember that the most important dental emergency to avoid in patients with diabetes is hypoglycemia.
