Tooth formation - delayed or absent
Delayed or absent tooth formation; Teeth - delayed or absent formation
When a person's teeth grow in, they may be delayed or not occur at all.
Considerations
The age at which a tooth comes in varies. Most infants get their first tooth between 6 and 9 months, but it may be earlier or later.
Sometimes, children or adults are missing teeth they never developed. Cosmetic or orthodontic dentistry can correct this problem.

When to Contact a Medical Professional
Talk to your health care provider if your child has not developed any teeth by 9 months of age.
What to Expect at Your Office Visit
The provider will perform a physical exam. This will include a detailed look at your child's mouth and gums. You will be asked questions such as:
- In what order did the teeth emerge?
- At what age did other family members develop teeth?
- Are any other family members missing teeth that never "came in"?
- What other symptoms are present?
