Tooth formation - delayed or absent

Alternate Names: Delayed or absent tooth formation; Teeth - delayed or absent formation

Considerations: 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.

Specific diseases can have a profound effect on tooth shape, tooth color, time of appearance, or absence of teeth. Delayed or absent tooth formation can result from many different conditions, including (but not limited to) those listed in this document.

Common Causes:

Home Care:

Call If:

  • your child has not developed any teeth by the time the child is 9 months old.

What To Expect: The medical history will be obtained and a physical examination performed.

Medical history questions documenting delayed or absent teeth in detail may include:

  • Have any of the teeth emerged?
    • Which teeth emerged and in what order?
    • Are the existing teeth abnormal in any way?
  • At what age did other family members develop teeth?
  • 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. The physical examination will include a detailed examination of the mouth and gums.

Diagnostic tests are usually not necessary unless a disorder is suspected as the cause of delayed or absent tooth formation. Most often, delayed tooth formation is a normal finding. Occasionally, dental x-rays will be needed.

After seeing your health care provider:
If a diagnosis was made by your health care provider as the cause of delayed or absent tooth formation, you may want to note that diagnosis in your personal medical record.
