Quick Answer: Some bite problems come from the position of the teeth, while others come from the size or position of the jaws. Surgical orthodontics may be considered when moving the teeth alone cannot create a bite that works properly.
Why the Source of the Bite Problem Matters
Two people can have similar-looking overbites, underbites, or open bites but need different treatment.
One person may have teeth that are tilted or positioned incorrectly. Braces or clear aligners may be able to correct the bite.
Another person may have an upper or lower jaw that sits too far forward, too far back, or unevenly. Moving the teeth may improve the appearance of the bite without correcting the underlying jaw position.
What Is a Dental Bite Problem?
A dental bite problem mainly involves the position of the teeth.
The teeth may be crowded, spaced, rotated, or tilted too far forward or backward. The jawbones may be positioned normally, but the teeth do not meet as they should.
These problems can often be treated with braces or clear aligners. The orthodontist moves the teeth into better positions while considering the bite, available space, gums, and long-term stability.
What Is a Skeletal Bite Problem?
A skeletal bite problem involves the size, shape, or position of the jawbones.
The upper jaw may sit too far forward. The lower jaw may sit too far back. One side may have developed differently from the other, causing the bite or facial balance to appear uneven.
Braces can move teeth within the jaws, but they cannot fully reposition a jaw once growth is complete. Surgical orthodontics may be considered when the jaw position is the main cause of the problem.
What Might You Notice Day to Day?
A jaw-related bite problem may affect more than the way the teeth look.
You may have trouble biting into food, feel that the teeth meet on only one side, notice uneven tooth wear, or struggle to close your lips comfortably. Some people also notice that the chin or jaw appears shifted when viewed from the front.
These signs do not prove that surgery is needed. They simply show why a complete orthodontic evaluation may be helpful.
Can a Bite Problem Come From Both the Teeth and Jaws?
Yes. Many complex bite problems involve both.
For example, a lower jaw may sit too far forward while the upper teeth tilt outward and the lower teeth tilt inward. This tooth movement may partly hide the jaw imbalance.
This is sometimes called dental compensation. Moving the teeth may improve the bite, but it does not always correct the underlying jaw position. The orthodontist must decide whether a non-surgical approach can create a bite that works well and is likely to remain stable.
How Does an Orthodontist Find the Cause?
An orthodontist looks at more than whether the teeth appear crooked.
The evaluation may include photographs, X-rays, digital scans, bite records, jaw position, facial balance, and growth. The orthodontist also checks where the teeth meet and whether the jaw shifts when the mouth closes.
These records help show whether the problem is mainly dental, mainly skeletal, or a combination of both.
Does a Severe Overbite or Underbite Always Require Surgery?
No. A severe-looking bite does not automatically mean corrective jaw surgery is necessary.
Some problems can be treated by moving the teeth, creating space, or using other orthodontic methods. In some younger patients, treatment may help guide growth or reduce the severity of certain developing bite problems.
Surgery is generally considered when the jaw position causes a significant problem that tooth movement alone cannot correct. The recommendation should be based on a full evaluation, not appearance alone.
What Happens If the Problem Comes From the Jaws?
The orthodontist will explain whether braces or aligners can create a bite that works well without surgery.
When surgery may be appropriate, an oral and maxillofacial surgeon also evaluates the jaw position. The orthodontist plans the tooth movement, while the surgeon determines whether a jaw procedure may be needed.
An evaluation does not commit you to surgery. Its purpose is to explain the cause of the problem, the available treatment paths, and the limits of each option.
Get a Clear Answer About Your Bite
It is difficult to tell whether a bite problem comes from the teeth or the jaws by looking in a mirror.
Miler Orthodontics can evaluate how your teeth and jaws fit together, explain what is causing the problem, and discuss which treatment options may be appropriate. If surgical orthodontics may be considered, the team can help coordinate the next step with an oral and maxillofacial surgeon.
