Normal vs. Severe Overbite
Class I Overbite
Many patients have a slight overbite that overlaps about a third to a half of the lower bite. Typically, treatment of a class I overbite is not necessary unless you are unhappy with your appearance.
Class II Overbite
Treatment is usually recommended for a moderate to severe overbite, known as a class II overbite or malocclusion, because it places you at higher risk of oral health issues such as gum disease, tooth decay, and temporomandibular joint (TMJ) disorder.
What does a severe overbite look like?
Look at Your Side Profile to Determine If You May Suffer from Malocclusion
A severe overbite is usually easy to identify because the upper teeth very noticeably protrude over the bottom teeth.
What causes malocclusion?
Early Childhood Habits Can Increase Your Risk of an Overbite
Some patients develop an overbite by no fault of their own. However, there are certain habits that may increase your risk, including:
- Prolonged pacifier use
- Tongue thrusting
- Nail biting
These habits exude repetitive force on the teeth and jaw, causing them to shift in ways that can require extensive and costly therapy.
What else causes overbites?
Some Causes Are Beyond Your Control
Some patients have an underdeveloped lower jaw or overdeveloped upper jaw due to genetics, resulting in an overbite.
Abnormal Tooth Eruption
If teeth erupt improperly, or if you have extra or abnormally shaped teeth, they can cause an overbite to develop.

How is an overbite diagnosed?
An Overbite Can Be Diagnosed During a Routine Exam
While your dentist can usually identify an overbite visually, he or she will also perform a physical dental exam of your bite to formally diagnose the condition. During the evaluation, your dentist will usually take digital x-rays. To more closely examine your smile, he or she can also use advanced technology to take 3-D images of your teeth and jaw. Using this information, your dentist can determine the type and severity of your overbite. Treating a severe overbite usually involves braces or other orthodontic treatments.
What should I do if I think I have an overbite?
Schedule an Exam with Your Dentist
If you think you have an overbite or are unhappy with your smile, schedule a consultation with your dentist. Treating your overbite can help prevent excessive wear on your teeth, relieve pain, and help you feel more confident in your smile.
