Oral Complications of Chemotherapy and Radiation Therapy in Children

Children who received high-dose chemotherapy or radiation therapy to the head and neck may not have normal dental growth and development. New teeth may appear late or not at all, and tooth size may be smaller than normal. The head and face may not develop fully. The changes are usually the same on both sides of the head and are not always noticeable.

Orthodontic treatment for patients with these dental growth and development side effects is being studied.
