Tooth Eruption Process

Typically children will have 20 primary teeth and 32 permanent teeth. Around 6 months of age, the first primary teeth appear and they usually erupt in the following order:

1. central incisor
2. lateral incisor
3. first molar
4. canine
5. second molar

As a general rule, four teeth erupt for every six months of life, mandibular teeth erupt before maxillary teeth, and teeth erupt sooner in females than males.

Around 5-6 years old, the permanent teeth start to erupt. Permanent teeth in the upper jaw erupt in a different order from permanent teeth on the lower jaw. The upper set of teeth erupt in the following order:

1. first molar
2. central incisor
3. lateral incisor
4. first premolar
5. second premolar
6. canine
7. second molar
8. third molar

The lower set of teeth erupt in the following order:
1. first molar
2. central incisor
3. lateral incisor
4. canine
5. first premolar
6. second premolar
7. second molar
8. third molar

By the time your child turns fourteen years old they should have all their permanent teeth.
