How to Keep Your Child's Teeth Healthy

When Should a Child Start Brushing Their Teeth?

0 to 3 Years

Before your baby's teeth erupt, use a soft, clean piece of gauze to clean your baby's gums after feeding.

When the first tooth erupts, around 6 months, begin gently brushing twice a day with a very soft-bristled child-size toothbrush. Use a very small amount of children's fluoride toothpaste (the size of a grain of rice). Make sure they spit out the toothpaste.

What Age Should a Child Go to the Dentist?

As soon as a child's first tooth appears (usually 4 to 6 months of age), you should schedule a visit to your dentist.

ADA guidelines suggest that the first dental visit should happen within 6 months of the first tooth eruption, and before their first birthday. If you child has had no teeth come in by 10 months, schedule a dental visit.

How to Prevent Cavities in Children

A baby is born with 20 primary (baby) teeth in their jaw. They usually begin coming through the gums 4 to 6 months of age. By age 3, most children will have a full set of 20 primary teeth. Tooth decay is the most common childhood dental problem, which leads to cavities, but it is preventable.

Sugary drinks are the most common cause of pediatric tooth decay and cavities.

Here are some tips to avoid cavities in children:

  • Limit sugar intake. Avoid sweetened water, soft drinks, and fruit juice. Water is the best drink for babies and toddlers.
  • Don't put your baby to sleep with a bottle. When a baby falls asleep with a bottle, some milk stays in their mouth and on their teeth. When the baby has finished feeding, remove the bottle or breast, and wipe their mouth with a damp cloth before bed.
  • Use clean pacifiers. Do not dip them in honey or sugar.
  • Try not to share saliva. Cavity causing bacteria can be passed from parent to child. Avoid putting spoons and pacifiers in your mouth before your child.
  • Clean the child's gums and teeth regularly. Use a soft damp cloth to wipe your child's gums before their first tooth erupts. As soon as their first tooth erupts start using a child-sized soft toothbrush and small amount of children's fluoride toothpaste (the size of a grain of rice). Make sure they spit out the toothbrush.
