A Parent's Guide to Children's Dental Health

Healthy dental habits start early. As a parent, you play the most important role in setting your child up for a lifetime of strong teeth and healthy gums. This guide covers everything you need to know — from your baby's first tooth to your teenager's orthodontic options.

When Should My Child First See a Dentist?

The American Academy of Pediatric Dentistry recommends scheduling your child's first dental visit by their first birthday or within six months of their first tooth appearing, whichever comes first. This early visit is less about treatment and more about building familiarity. We will check for early signs of decay, evaluate jaw development, and give you personalized guidance on caring for your child's teeth at home.

Early visits also help children see the dentist's office as a normal, non-threatening place — which goes a long way toward preventing dental anxiety later in life.

Brushing and Flossing by Age

Infants (0 to 12 Months)

Before teeth appear, gently wipe your baby's gums with a clean, damp washcloth after feedings. Once the first tooth erupts, begin brushing with an infant-sized toothbrush and a rice-grain-sized smear of fluoride toothpaste twice daily.

Toddlers (1 to 3 Years)

Continue brushing twice a day with a small smear of fluoride toothpaste. Children this age lack the coordination to brush effectively on their own, so you will need to do the brushing for them. Start introducing flossing once two teeth touch each other.

Preschool and School Age (3 to 8 Years)

Increase the toothpaste amount to a pea-sized dollop. Let your child practice brushing, but follow up by brushing again yourself to make sure all surfaces are clean. Most children do not develop the fine motor skills for thorough independent brushing until around age seven or eight.

Tweens and Teens (9 and Up)

By this age, children should be brushing and flossing independently, but it helps to check in regularly. This is also the stage when orthodontic evaluation becomes important — the American Association of Orthodontists recommends an initial screening by age seven.

Making Dental Care Fun

Getting kids excited about brushing does not have to be a battle. Here are strategies that work:

• Use a timer or a song: Brush for the full two minutes by playing their favorite song or using a fun brushing app

• Let them choose their toothbrush: Character-themed brushes and fun colors give kids a sense of ownership

• Brush together: When children see parents taking care of their own teeth, they learn that dental hygiene is a normal part of daily life

• Positive reinforcement: Praise consistent brushing with stickers, a chart, or small rewards

The Power of Dental Sealants

Dental sealants are thin, protective coatings applied to the chewing surfaces of back teeth (molars), where most cavities in children develop. The procedure is quick, painless, and highly effective — sealants can reduce the risk of cavities in molars by up to 80%. We typically recommend sealants as soon as your child's permanent molars come in, usually around ages six and twelve.

Diet and Your Child's Teeth

What your child eats and drinks directly impacts their dental health. Limit sugary snacks, sticky candy, and acidic drinks like juice and soda. When your child does have something sweet, it is better to consume it with a meal rather than as a standalone snack, because mealtime saliva production helps neutralize acids.

Great tooth-friendly snacks include cheese, yogurt, fresh vegetables, nuts, and crunchy fruits like apples.

Building a Foundation for Life

The dental habits your child develops now will shape their oral health for decades. Regular checkups, consistent brushing and flossing, smart dietary choices, and preventive treatments like sealants and fluoride all work together to keep young smiles bright and cavity-free.
