Tooth number chart- eruption charts. 

Did you know you start life with 20 baby teeth (primary teeth) typically. At around 6 months primary teeth begin to erupt. As you grow your baby teeth shed and your permanent teeth grow in. By your early twenties you’ll have all 32 permanent teeth.

Dentists use a tooth chart to label and identify your teeth. This tooth eruption chart shows where all the teeth inside your mouth are from the back molars to the front incisors.
