Dr. King Answers: What Is an Orthodontic Expander?

Q: What is an orthodontic expander?

A: This is a special appliance used to widen a narrow jaw.

Some patients are born with a narrow or constricted upper jaw that results in crossbites and crowded teeth. Crossbites are when the upper teeth bite inside of the lower teeth.


An orthodontic expander, also known as a palatal expander [see image], is used to gradually widen the narrow jaw over the course of about 6 months. This is usually done between the ages of 7-9 years, while the bone is soft and growing.

At King Orthodontics, I custom-make expanders to fit the exact size and shape of a patient's jaw. This results in a more comfortable and efficient process.

Keep smiling, and see you soon for a free consultation.
