Below are some basics parents need to know about primary teeth with regards eruption (coming in) times, exfoliation (shedding) times and about the structure of teeth.
- There are 20 primary teeth
- 8 Molars (chewing teeth)
- 4 Canines (vampire teeth)
- 8 Incisors (front teeth)
- They are named A through T
- The sequence of eruption is more important than the timing. Sometimes this order is different, but this does not necessarily mean that anything is wrong. It may just be a sign that you should check in with your child's dentist. Here is the normal sequence (keep in mind that it does vary from child to child) beginning with the teeth that should erupt first to the teeth that should erupt last:
- Lower central incisors
- Lower lateral incisors
- Upper central incisors
- Upper lateral incisors
- Lower first molars
- Upper first molars
- Lower canines
- Upper canines
- Lower second molars
- Upper second molars
- There are 4 main tissues that make up all teeth
- Enamel - The outermost, hardest, and most caries/cavity resistant tissue in teeth
- Dentin - The tissue directly under the enamel (or cementum when speaking of the roots.) This tissue is not as hard as enamel, it is still however harder than bone.
- Pulp - Consists completely of soft tissue. This is where all the nerves and blood vessels are.
- Cementum - The outermost part of the roots of the tooth. This tissue is responsible for connecting your teeth to the bone supporting them.
