A baby teeth chart by age, with a teething tracker
When will my baby’s first tooth come through, and in what order do the rest follow? This baby teeth chart lists all 20 milk (primary) teeth with the usual age each one comes in and the usual age it falls out, shown on a mouth diagram you can tap. Each tooth carries its US letter (A–T) and its international FDI number (51–85), so you can match what a dentist writes down.
It is also a simple teething tracker: pick a tooth, tap “Came in today” or type the date, and later record when it falls out. Add your child’s date of birth and the chart shows their age, the age each tooth arrived, and which teeth are in their usual window now. The dates stay in this browser on this device.
This page is general information, not medical or dental advice. Teething timing varies a lot from child to child.
How to use the Baby Teeth Chart & Teething Tracker
- Optionally enter your child’s date of birth.
- Tap a tooth in the diagram (or a row in the table) to see its name, letter, FDI number and usual ages.
- When a tooth breaks through, tap Came in today or enter the date under Came in on.
- Years later, record lost teeth with Fell out today or a date.
- Switch the labels between Letters A–T and FDI 51–85, and download your dates as a CSV.

Baby teeth chart: when each tooth comes in and falls out
These are the standard dental reference ranges, as used in dental textbooks and published by the American Dental Association. The NHS gives the same order in round numbers: front teeth (central incisors) around 6 months, the teeth either side (lateral incisors) around 8 months, first molars around 12 months, canines around 18 months and second molars around 24 months. Most children have all their milk teeth by the age of 2 to 3. Notice that the first molars usually arrive before the canines.
| Tooth | Upper: comes in | Upper: falls out | Lower: comes in | Lower: falls out |
|---|---|---|---|---|
| Central incisor | 8–12 months | 6–7 years | 6–10 months | 6–7 years |
| Lateral incisor | 9–13 months | 7–8 years | 10–16 months | 7–8 years |
| Canine (cuspid) | 16–22 months | 10–12 years | 17–23 months | 9–12 years |
| First molar | 13–19 months | 9–11 years | 14–18 months | 9–11 years |
| Second molar | 25–33 months | 10–12 years | 23–31 months | 10–12 years |
Baby teeth chart letters and numbers
In the US, dentists label milk teeth with letters: A to J run along the upper jaw from the child’s right second molar to the left second molar, and K to T run along the lower jaw from the left second molar back round to the right. Elsewhere the FDI system is common: the first digit is the quarter of the mouth (5 upper right, 6 upper left, 7 lower left, 8 lower right) and the second counts back from the front tooth (1 central incisor to 5 second molar). So the first teeth to appear are usually O and P, or 71 and 81.
Teething signs and what helps
- Signs listed by the NHS include a sore, red gum where the tooth is coming through, a slightly raised temperature below 38 °C, one flushed cheek, a rash on the face, rubbing an ear, more dribbling, gnawing on things, being more fretful and sleeping badly.
- Teething rings give something safe to chew. Some can be cooled in the fridge — never the freezer — and never tie one round your baby’s neck.
- Sugar-free paracetamol (from 2 months) or ibuprofen (from 3 months) can ease symptoms; follow the pack or a pharmacist. Children under 16 should not have aspirin. There is a lack of evidence that teething gels work.
- Brush as soon as teeth come through, with a tiny smear of fluoride toothpaste up to age 3 and a pea-sized amount from 3 to 6, and take your child along to your own dental check-ups.
Baby Teeth Chart & Teething Tracker FAQ
When do babies start teething?
Most start at around 6 months, according to the NHS, but some begin before 4 months and some after 12 months.
What order do baby teeth come in?
Usually the lower central incisors first, then the upper central incisors, the lateral incisors, the first molars, the canines and finally the second molars. The baby teeth chart above shows the age range for each.
When do baby teeth fall out?
Usually from about 6 to 7 years, starting with the central incisors, and the last (canines and second molars) at about 10 to 12 years.
What are the letters on a baby teeth chart?
The US Universal system labels the 20 milk teeth A–T, starting at the upper right second molar and ending at the lower right second molar. Switch to FDI to see the 51–85 numbers instead.
Does teething cause a fever?
The NHS lists a slightly raised temperature below 38 °C as a possible sign. A temperature of 38 °C or more should not be put down to teething — get medical advice.
