From Baby Teeth to Permanent Grins: A Parent's Guide to Understanding Teeth Development

As parents, watching your child’s various milestones is exciting. One significant event in a child’s life is their dental development, which starts with that first cute, tiny tooth poking through their gums. You may wonder: When can I expect my baby’s first tooth? When do baby teeth fall out? When do kids get their permanent teeth?

This blog post will answer those questions and more! 

Eruption of Primary Teeth

According to the American Dental Association, a baby’s first tooth usually erupts between the ages of 6 and 12 months of age. By age three, a child should have a full set of twenty primary teeth. Keep in mind that this will vary from child to child. 

Upper TeethWhen tooth emergesWhen tooth falls out
Central incisor8 to 12 months6 to 7 years
Lateral incisor9 to 13 months7 to 8 years
Canine (cuspid)16 to 22 months10 to 12 years
First molar13 to 19 months9 to 11 years
Second molar25 to 33 months10 to 12 years
Lower Teeth  
Second molar23 to 31 months10 to 12 years
First molar14 to 18 months9 to 11 years
Canine (cuspid)17 to 23 months9 to 12 years
Lateral incisor10 to 16 months7 to 8 years
Central incisor6 to 10 months6 to 7 years

Caring for Primary Teeth

As soon as the first tooth appears, it’s essential to start taking care of your child’s oral hygiene. Start by gently wiping the tooth with a damp, clean washcloth. As more teeth emerge, introduce an infant toothbrush and a minimal amount of fluoride-containing toothpaste. The CDC recommends a rice grain-sized amount for children under three. Supervise your child’s brushing until they can do it properly themselves, typically around the age of six.

Loss of Primary Teeth

Losing baby teeth marks a new stage of growing up. Generally, children start losing primary teeth around age six, though this can vary. The first to fall out are often the lower central incisors, just like when they first erupted. This process typically continues until they are about 12 years old, making space for the permanent teeth to take their place.

Eruption of Permanent (Adult) Teeth

As your child loses their baby teeth, permanent teeth begin to erupt. This process starts around six years old, and unlike primary teeth eruption, this happens gradually throughout the mouth. By around age 21, all 32 adult teeth, including wisdom teeth, should be in place. Keep in mind, however, that not everyone develops wisdom teeth, and some may need to have theirs removed due to impaction or other issues.

Upper TeethWhen tooth emerges
Central incisor7 to 8 years
Lateral incisor8 to 9 years
Canine (cuspid)11 to 12 years
First premolar (first bicuspid)10 to 11 years
Second premolar (second bicuspid)10 to 12 years
First molar6 to 7 years
Second molar12 to 13 years
Third molar (wisdom teeth)17 to 21 years
Lower TeethWhen tooth emerges
Third molar (wisdom tooth)17 to 21 years
Second molar11 to 13 years
First molar6 to 7 years
Second premolar (second bicuspid)11 to 12 years
First premolar (first bicuspid)10 to 12 years
Canine (cuspid)9 to 10 years
Lateral incisor7 to 8 years
Central incisor6 to 7 years

Caring for Permanent Teeth

Caring for your child’s adult teeth is crucial, as these are meant to last a lifetime. Encourage proper brushing techniques and the use of dental floss to maintain good oral hygiene. Regular dental checkups, at least twice a year, are highly recommended. Make sure your child eats a balanced diet, and limit sugary snacks and drinks to ensure their teeth stay strong and healthy.

Watching your child’s teeth grow from baby to adult is a fascinating journey. By understanding this process you can help set the stage for a lifetime of healthy teeth and a beautiful, permanent grin.
