Baby teething chart and calendar

Babies usually get 20 primary (baby) teeth, in pairs, in a fairly predictable order. The calculator uses the American Dental Association (ADA) eruption chart:

Order	Tooth	Comes in	Falls out
1	Lower central incisors	6–10 months	6–7 years
2	Upper central incisors	8–12 months	6–7 years
3	Upper lateral incisors	9–13 months	7–8 years
4	Lower lateral incisors	10–16 months	7–8 years
5	Upper first molars	13–19 months	9–11 years
6	Lower first molars	14–18 months	9–11 years
7	Upper canines	16–22 months	10–12 years
8	Lower canines	17–23 months	9–12 years
9	Lower second molars	23–31 months	10–12 years
10	Upper second molars	25–33 months	10–12 years

By around 33 months (close to age 3), most children have all 20 baby teeth.

From your baby's date of birth, the calculator works out the date range for every pair of teeth and compares it with today:

• Probably in already (filled): the window has passed.
• Due now (yellow): today falls within the window.
• Coming later (outline): the window hasn't started.

The tooth map shows the upper and lower teeth with numbers for the usual order, and the table lists each pair with its age range, the calendar dates for your baby and when the tooth typically falls out. The headline tells you how many teeth may be in by now, and which pair is next if none is due.

These are averages. Some babies get their first tooth at 4 months, others not until after their first birthday, and the order can differ. Both are usually normal. If no teeth have appeared by around 18 months, mention it to your pediatrician or dentist.

The section When do permanent teeth come in? lists the adult teeth with their usual age ranges and the matching years for your child:

Tooth	Upper	Lower
First molars (6-year molars)	6–7 years	6–7 years
Central incisors	7–8 years	6–7 years
Lateral incisors	8–9 years	7–8 years
Canines	11–12 years	9–10 years
First premolars	10–11 years	10–12 years
Second premolars	10–12 years	11–12 years
Second molars (12-year molars)	12–13 years	11–13 years
Third molars (wisdom teeth)	17–21 years	17–21 years

The first permanent molars come in behind the baby teeth without replacing any, so parents often miss them. They're important to brush well.

Common signs of teething include drooling, chewing on things, swollen gums and fussiness. A high fever or diarrhea is not a typical sign of teething, so call your pediatrician if your baby has them.

To soothe sore gums, gently rub them with a clean finger or offer a firm, chilled (not frozen) teething ring. The U.S. Food and Drug Administration warns against teething necklaces and bracelets, which are a choking and strangulation risk, and against benzocaine teething gels for children under 2.

Start cleaning teeth as soon as the first one appears, with a soft brush and a smear of fluoride toothpaste the size of a grain of rice. Dental groups recommend a first dental visit by your child's first birthday.
