About this tool
Teething Timeline Tracker
Expected eruption dates for all 20 baby teeth from a date of birth, using the standard primary tooth eruption chart.
Teething Timeline Tracker converts a child's date of birth into calendar dates for each of the 20 primary teeth, using the eruption windows on the standard primary tooth chart published by the American Dental Association. It orders the ten tooth pairs the way they normally arrive — lower central incisors first at 6-10 months, upper second molars last at 25-33 months — and marks each pair as upcoming, due now or past its usual window. Parents can tick teeth off as they appear and see when the first dental check-up is due.

Common use cases
- Work out roughly when a 7-month-old's first tooth is likely to break through, and which pair comes next.
- Check whether a 20-month-old who still has no molars is inside or outside the usual 13-19 month window.
- Keep a dated record of which teeth have arrived to take to the first dental appointment.
- Explain to a worried grandparent that upper canines routinely arrive between 16 and 22 months.
Frequently asked questions
When do babies get their first tooth?
The lower central incisors usually come through between 6 and 10 months, making them the first teeth for most babies. A first tooth anywhere from 4 to 12 months is still within normal variation.
In what order do baby teeth come in?
The usual order is lower central incisors (6-10 months), upper central incisors (8-12), upper lateral incisors (9-13), lower lateral incisors (10-16), first molars (13-19), canines (16-23), then second molars (23-33 months). All 20 primary teeth are typically in place by about age three.
When should a child first see a dentist?
The American Dental Association and the American Academy of Pediatric Dentistry advise a first dental visit when the first tooth appears and no later than the first birthday. This tool calculates that date from the date of birth you enter.
Does teething cause fever?
No — research consistently finds teething may cause mild gum irritation, drooling and a slightly raised temperature at most, but not a true fever above 38 °C, diarrhoea or vomiting. Those symptoms need a doctor's assessment rather than being put down to teething.
