5 Dental Milestones to Watch for in Your Child’s First 10 Years

Your child’s smile grows and changes almost as quickly as they do. From that first tiny tooth to the arrival of adult molars, your child will reach several important dental milestones in their first decade of life. Knowing what to expect helps parents support healthy development and avoid common dental issues.

At Doctor Sugar Pediatric Dentistry in Paradise Valley, AZ, we love guiding families through each stage with expert care and a lot of smiles. Let’s break down the five major dental milestones to watch for during your child’s first 10 years.

1. First Tooth: Around 6–12 Months

It starts with a drooly grin and maybe a little fussiness—your baby’s first tooth is on the way. The lower front teeth usually arrive first, followed by the upper front teeth.

Why it matters: As soon as the first tooth erupts, it's time to start brushing and to schedule your child's first dental visit. This helps establish healthy habits early and allows your pediatric dentist to check for any developmental concerns.

2. Full Set of Baby Teeth: By Age 3

Most children have a complete set of 20 primary (baby) teeth by age 3. These teeth are important for chewing, speaking, and holding space for permanent teeth.

Why it matters: Baby teeth may be temporary, but they need just as much care as adult teeth. Regular dental visits, good brushing routines, and fluoride treatments are essential to keep these teeth strong and cavity-free.

3. Losing the First Tooth: Around Age 6

Losing a tooth is a big deal for kids—and for parents too! The first baby tooth usually falls out around age 6, making room for the first permanent teeth.

Why it matters: As adult teeth begin to emerge, your pediatric dentist will monitor spacing, bite alignment, and jaw development. This is also a great time to talk about orthodontic evaluations if needed.

4. First Permanent Molars: Ages 6–7

These “six-year molars” come in behind the baby teeth and are often overlooked because they don’t replace any teeth. But they’re key to your child’s dental foundation.

Why it matters: Permanent molars are more prone to cavities, especially in kids who are still mastering their brushing technique. Dental sealants can provide extra protection on these back teeth.

5. Early Orthodontic Checkup: Around Age 7

The American Association of Orthodontists recommends that children have their first orthodontic evaluation by age 7—even if they don’t have any visible issues.

Why it matters: Catching problems early, like crowding or bite issues, can prevent more serious complications later. Your pediatric dentist in Paradise Valley, AZ will let you know if your child is developing as expected or may benefit from early intervention.
