Children’s Dental Development

Throughout your child’s life, they will undergo dental development. Stages being with initial teething, followed by primary teeth eruption, to a few years of baby teeth falling out, then permanent teeth growing, and finally wisdom teeth coming in. As long as you take care of your children’s teeth and you teach them proper oral hygiene, along with regular dental checkups, the process of their teeth development will go smoothly.

The following lists show when primary teeth erupt and shed in children. The data is based on the Canadian Dental Association.
