Dental Care by Age: Your Smile Timeline (Infographic)

Parents often ask us when a child should first see a dentist, when braces are worth checking, or whether wisdom teeth always need to come out. The answers depend on age, so we put the key moments on one simple timeline. Save it, share it with family, or use it as a reminder of what to ask at your next check-up.

Babies and toddlers (0 to 3 years)

The first tooth usually appears around six months, though anything from a few months to over a year can be normal. Start cleaning as soon as it appears, with a soft baby brush and a smear of fluoride toothpaste no bigger than a grain of rice. Avoid putting a baby to bed with a bottle of milk or juice, which is one of the main causes of early decay. Our baby teeth chart shows when each tooth usually arrives, and our guide to baby tooth decay explains the early signs.

The first dental visit should be by the first birthday. It’s short and relaxed: we look at the teeth, check for early decay and answer your questions about teething, thumb-sucking and diet. Read your child’s first dental visit for what to expect.

Children (3 to 12 years)

From age three, use a pea-sized amount of fluoride toothpaste and keep helping with brushing until about seven, when most children can manage on their own. The first adult molars arrive around six, behind the baby teeth, and are easy to miss. Fissure sealants seal the deep grooves on these teeth and are a simple way to prevent decay. Around seven is also a good age for a first bite check, so crowding or a cross-bite can be spotted early. See children’s dentistry and the 2-minute brushing timer.

Teenagers (12 to 18 years)

Most adult teeth are through by 12 to 13, which makes it a common time to start braces or clear aligners. Sports mouthguards are worth it for contact sports. Fizzy drinks and energy drinks are a big cause of erosion at this age, so water between meals makes a real difference.

Young adults and wisdom teeth

Wisdom teeth usually come through between 17 and 25. Many cause no trouble, and not all need removal. An X-ray shows whether there is room. Swelling over a half-erupted wisdom tooth, called pericoronitis, is common and should be checked. Read more in wisdom tooth pain and tooth extraction.

Adults

For most adults, a check-up and cleaning every six months keeps decay and gum disease small and easy to treat. Bleeding when you brush is the most common early sign of gum disease and is worth checking, not ignoring. Dental check-ups and cleaning are safe during pregnancy; see dental care during pregnancy. If you grind your teeth at night, a custom night guard protects them.

Later life (60+)

Many medicines cause dry mouth, which raises the risk of decay, especially around the roots of teeth as gums recede. Sipping water, sugar-free gum and a high-fluoride toothpaste, if your dentist recommends it, can help. If you wear dentures, have them checked regularly, because the gums change shape over time and a loose denture can cause sore spots.
