Tooth formation - delayed or absentDelayed or absent tooth formation; Teeth - delayed or absent formation
The timing of the first appearance of teeth varies. Most infants get their first tooth between 6 and 9 months, although earlier or later eruption may be normal.
In some cases, children or adults are missing teeth they never developed. In such cases cosmetic or orthodontic dentistry can correct the absence of those teeth.
Specific diseases can have a profound effect on tooth shape, tooth color, time of appearance, or tooth absence. Delayed or absent tooth formation can result from many different conditions, including:
- Apert syndrome
- Cleidocranial dysostosis
- Down syndrome
- Ectodermal dysplasia
- Ellis-van Creveld syndrome
- Incontinentia pigmenti achromians
When to Contact a Medical Professional
If your child has not developed any teeth by the time the child is 9 months old, consult your health care provider.
What to Expect at Your Office Visit
The health care provider will perform a physical examination, including a detailed examination of the mouth and gums, and ask questions such as:
- In what order did the teeth emerge?
- At what age did other family members develop teeth?
- Are there any other family members that have teeth that never "came in"?
- What other symptoms are also present?
An infant with delayed or absent tooth formation may have other symptoms and signs that, when taken together, define a specific syndrome or condition.
Diagnostic tests are usually not necessary unless a disorder is suspected as the cause. Most often, delayed tooth formation is a normal finding. Occasionally, dental x-rays will be needed.
