📘 About the Teething
Babies usually get their first tooth — a lower front tooth — between 6 and 10 months, and all 20 milk teeth by about 3 years. Enter your baby's age to see which teeth are likely through, which may be coming now and which come next.
Timing varies a lot between children and often runs in families; a few months early or late is normal.
