Tooth formation - delayed or absent

Delayed or absent tooth formation; Teeth - delayed or absent formation; Oligodontia; Anodontia; Hypodontia; Delayed dental development; Delayed tooth eruption; Late tooth eruption; Delayed dental eruption

 

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 4 and 8 months, but it may be earlier or later.

 

Causes

 

Specific diseases can affect tooth shape, tooth color, when they grow in, 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
  • Hypothyroidism
  • Hypoparathyroidism
  • Incontinentia pigmenti achromians
  • Progeria

 

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?

An infant with delayed or absent tooth formation may have other symptoms and signs that indicate a specific medical condition.

Medical tests are not often needed. Most of the time, delayed tooth formation is normal. Dental x-rays may be done.

Sometimes, children or adults are missing teeth they never developed. Cosmetic or orthodontic dentistry can correct this problem.
