Tooth - abnormal shape

An abnormally shaped tooth is any tooth that has an irregular shape.

Alternative Names

Hutchinson incisors; Abnormal tooth shape; Peg teeth; Mulberry teeth; Conical teeth

Considerations

The appearance of normal teeth varies, especially the molars. Abnormally shaped teeth can result from many different conditions. Specific diseases can affect tooth shape, tooth color, time of appearance, or absence of teeth.

When to Contact a Medical Professional

Talk to a dentist or health care provider if the shape of your child's teeth appears to be abnormal.

What to Expect at Your Office Visit

The dentist will examine the mouth and teeth. You will be asked questions about your child's medical history and symptoms, such as:

  • Does the child have any medical conditions that may cause abnormal tooth shape?
  • At what age did the teeth appear?
  • In what order did the teeth appear?
  • Are there other tooth problems (color, spacing)?
  • What other symptoms are also present?

Fillings, dental restorations, crowns, or bridges may be needed to correct the abnormal shape and improve the appearance of the teeth.

Dental x-rays and other diagnostic tests may be done.
