7 Childhood dental milestones that parents need to know

Just because most newborns don’t have teeth yet, it’s never too early for new parents to start a dental regimen for their baby.

“Parents shouldn’t wait until teething starts to think about their baby’s dental health,” says Dr. Jamie Reynolds, an orthodontist, national and international lecturer and author of “World Class Smiles Made in Detroit” (

Reynolds says it is important for parents to give children a proper start if they are to enjoy a lifetime of good dental health. He offers these milestones for parents to keep in mind:

During the pregnancy

A child’s dental care really starts before the child is born, Reynolds says. Baby teeth begin to form before birth, so pregnant women should make sure to eat a balanced, nutritious diet and should get an adequate amount of vitamins and minerals, he says. They should have a complete dental exam and have any cavities or gum disease treated.

After birth, but before teeth arrive

Before the baby’s teeth have even erupted, keep the baby’s mouth clean by wiping down the gums twice a day with gauze or a moist washcloth after the baby’s last feeding.

At about six months, teeth begin to come in

Parents should start brushing their children’s baby’s teeth as soon as they come in, Reynolds says. The American Dental Association (ADA) recommends using fluoride toothpaste the size of a grain of rice on a child-sized toothbrush twice a day.

At age 3, a full set of baby teeth have probably arrived
By age 3, most children have a full set of baby teeth – 20 of them – at which point the ADA recommends upping the amount of toothpaste from the size of a grain of rice to the size of a pea.

Around age 6, most children should be able to brush on their own.

At this point, children can start using an adult-sized amount of fluoride toothpaste when they brush, Reynolds says. Children should have their teeth flossed as soon as two teeth are touching. Children typically can floss on their own starting at about 7 years old.

The first dental visit

The American Academy of Pediatric Dentistry recommends an initial visit to the dentist when the first tooth erupts, or no later than baby’s first birthday. From then on, parents should make twice yearly visits.

When children should see an orthodontist

The American Association of Orthodontists recommends all children see an orthodontist by the age of 7. Even though it may sound early, some issues can be addressed more quickly when caught early, such as issues with the growth of the jaw bone, remaining baby teeth, impacted teeth, the number of teeth growing in, and more, Reynolds says. Fortunately, he says, the majority of children this age will not need treatment.

One of the most important things parents can do is model good oral health behavior so children can see how seriously their parents take care of their oral hygiene,” Reynolds says. “It’s important that children see their parents brush and floss, avoid sugary snacks, and make regular visits to the dentist.”
