What Is Tooth Eruption?

Tooth eruption simply means the process of teeth moving into the mouth. Every child follows their own timeline, but most kids go through the same general pattern.

There are two sets of teeth:

• Primary teeth (baby teeth): 20 total

• Permanent teeth (adult teeth): 32 total

Understanding when these teeth come in helps parents support good oral care from the start.

Stage 1: Infant Teeth (6–12 Months)

The first baby teeth usually appear around 6 months—sometimes earlier, sometimes later.
The very first to arrive are typically:

• Lower central incisors (bottom front teeth)

• Followed by upper central incisors

Common signs of teething:

• Drooling

• Chewing on hands or toys

• Irritability

• Mild gum swelling

What parents can do:
Use teething rings, gently massage the gums, and schedule your child’s first dental visit by age one.

---

Stage 2: Toddler Teeth (1–3 Years)

During this stage, your child’s smile fills in quickly. The next teeth to erupt are:

• Lateral incisors (next to the front teeth)

• First molars

• Canines (the pointed teeth)

• Second molars

By age 3, most children have a complete set of 20 baby teeth.

What parents can do:
Brush twice daily with a small smear of fluoride toothpaste, and begin teaching brushing habits.

---

Stage 3: Rest Stage (3–6 Years)

Between ages 3 and 6, the mouth stays mostly the same.
No new teeth erupt, but the jaw grows to make room for permanent teeth.

What parents can do:
Keep up with regular dental checkups every six months. Early monitoring helps us catch issues like crowding or bite problems.

Stage 4: Mixed Dentition (6–12 Years)

This is when baby teeth fall out and adult teeth begin coming in. It’s a big milestone!

Teeth that usually appear first:

• First permanent molars (“6-year molars”)

• Lower and upper central incisors

Over the next several years, children will also get:

• Lateral incisors

• Canines

• Premolars (which replace baby molars)

• Second molars (around age 12)

Kids typically lose their last baby tooth by age 12 or 13.

What parents can do:
Focus on fluoride, brushing, flossing, and monitoring sugar intake. This is a high-cavity stage, so preventive care is essential.

---

Stage 5: Teen Teeth (12–21 Years)

By the teen years, most permanent teeth are in place.

The final teeth to erupt:

• Third molars (wisdom teeth): Ages 17–21, if they erupt at all

Some teens never develop wisdom teeth, while others need them removed due to lack of space.

What parents can do:
Follow your dentist’s guidance about wisdom teeth evaluations and orthodontic treatment if needed.

What If Teeth Come In Late or Early?

Every child’s schedule is different.
Early or late eruption is usually normal unless accompanied by:

• Severe crowding

• Missing teeth

• Delayed baby tooth loss

• Pain or swelling

• Difficulty chewing

If you’re ever unsure, the team at Inspire Kids Dental is happy to assess your child’s tooth development with a gentle exam and X-rays if needed.
