Wondering which baby teeth should be in by now, and which ones are coming next? Enter your child’s birth date below. The calculator compares your child’s age with the American Dental Association (ADA) primary tooth eruption chart and shows which teeth usually appear in that window. Every child is different: a few months early or late is common and usually not a concern.

Baby Teeth Eruption Chart (ADA)
Children usually get 20 primary (baby) teeth. The first ones, typically the lower front teeth, often appear around 6 months. The table below lists the ADA’s typical ranges for when each tooth comes in and falls out.
| Tooth | Comes in (erupts) | Falls out (sheds) |
|---|---|---|
| Upper teeth | ||
| Central incisor | 8–12 months | 6–7 years |
| Lateral incisor | 9–13 months | 7–8 years |
| Canine (cuspid) | 16–22 months | 10–12 years |
| First molar | 13–19 months | 9–11 years |
| Second molar | 25–33 months | 10–12 years |
| Lower teeth | ||
| Central incisor | 6–10 months | 6–7 years |
| Lateral incisor | 10–16 months | 7–8 years |
| Canine (cuspid) | 17–23 months | 9–12 years |
| First molar | 14–18 months | 9–11 years |
| Second molar | 23–31 months | 10–12 years |
The Usual Order Baby Teeth Come In
- Lower central incisors (bottom front two): often the first, around 6–10 months.
- Upper central incisors (top front two): around 8–12 months.
- Lateral incisors (next to the front teeth): roughly 9–16 months.
- First molars: roughly 13–19 months.
- Canines (pointed teeth): roughly 16–23 months.
- Second molars (back teeth): roughly 23–33 months.
Notice that the first molars often arrive before the canines. That surprises many parents, but it is the normal pattern.
Common Teething Signs
- Drooling and chewing on hands or toys
- Fussiness or irritability
- Swollen, tender gums
- Changes in sleep
According to the American Academy of Pediatrics, teething should not cause a high fever or diarrhea. If your baby has those symptoms, contact your pediatrician, because something else may be going on.
Safe Ways to Soothe a Teething Baby
- Gently rub the gums with a clean finger.
- Offer a firm, chilled (not frozen) teething ring.
- Wipe away drool often to protect the skin.
What to avoid: The U.S. FDA has warned parents not to use teething necklaces or bracelets (choking and strangulation risk) and not to use benzocaine teething gels for young children. Ask your pediatrician before giving any medicine.
Caring for New Baby Teeth
- Clean your baby’s gums with a soft, damp cloth even before teeth arrive.
- Once the first tooth appears, brush twice a day with a soft infant toothbrush and a smear of fluoride toothpaste about the size of a grain of rice, as the ADA recommends for children under 3.
- Schedule the first dental visit by the first birthday or within six months of the first tooth.
When to Talk to a Dentist
- No teeth by around 18 months
- Teeth coming in far out of the usual order, or very discolored
- A baby tooth knocked out or broken after a fall
- Signs of decay, such as white or brown spots near the gumline
Frequently Asked Questions
When do babies get their first tooth?
Many babies get their first tooth around 6 months, usually a lower front tooth. The ADA range for the lower central incisors is 6–10 months, and some babies start earlier or later.
How many baby teeth do children have?
Children usually have 20 primary teeth: 10 on top and 10 on the bottom.
When do all baby teeth come in?
Most children have all 20 baby teeth by about age 3. The upper second molars are often the last, at around 25–33 months.
Is it normal for teeth to come in late?
A delay of a few months is common. If there are no teeth by around 18 months, ask your pediatric dentist to take a look.
