Healthy baby teeth help children eat, speak and smile, and they guide the adult teeth into place. Good habits started early last for life.

Baby: the first tooth

  • The first tooth usually appears at around six months, but it can be earlier or later.
  • Start brushing as soon as it appears, with a soft small brush.
  • Many dental bodies advise a first dental visit when the first tooth appears or by the first birthday.
  • Do not put a baby to bed with a bottle of milk or sugary drink.

Toddlers and pre-schoolers

  • Use fluoride toothpaste: a smear (the size of a grain of rice) for children under three, and a pea-sized amount from three to six. Ask your dentist what is right where you live.
  • Brush twice a day, morning and before bed. Help your child, and spit rather than rinse.
  • Keep sweet drinks for rare treats. Water and milk are the best everyday drinks.

Early school years

  • Children usually need help with brushing until around seven or eight.
  • First adult molars come through around age six, behind the baby teeth. Many parents do not notice them. Ask the dentist about protective sealants.
  • Baby teeth start to loosen from around six. Let them come out naturally.

Ages 9 to 12

  • Most baby teeth are replaced by about age 12.
  • If teeth look crowded or crooked, ask your dentist whether an orthodontic check is a good idea.
  • Use a mouthguard for contact sports.

Helping a nervous child

Choose a calm, child-friendly dentist, speak positively, and avoid words like "hurt". Find a paediatric dentist or any verified dentist.
