Delayed or absent tooth formation; Teeth - delayed or absent formation

If your child has not developed any teeth by the time the child is 9 months old, consult your health care provider.

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.
