Why Is It Necessary To Perform Underbite Surgery?
Posted on 1/1/2026 by Thomas Plunkett DMD |
 Have you ever looked in the mirror and noticed that your lower teeth stick out further than your upper teeth? This is often called an underbite, and while it might seem like just a cosmetic issue, it can actually cause a number of problems. Let's explore why fixing an underbite, sometimes with something called underbite surgery, might be necessary for your overall health and well-being.
What is an Underbite?
An underbite, also known as a Class III malocclusion, happens when your lower jaw grows forward more than your upper jaw. This causes your lower teeth to sit in front of your upper teeth when you close your mouth. Sometimes it's mild, and sometimes it's quite noticeable. The severity of the underbite often dictates the potential problems it can cause.
The Problems Underbites Can Cause
Beyond just appearances, underbites can lead to a range of oral and general health concerns.
| • |
Difficulty Chewing: When your teeth don't line up correctly, it can be hard to properly chew your food. This can lead to digestive issues, because you aren't breaking down food as efficiently as you should. |
| • |
Speech Problems: A significant underbite can affect your ability to pronounce certain sounds clearly. This can impact your confidence and communication. |
| • |
Jaw Pain and Headaches: The misalignment caused by an underbite puts extra stress on your jaw joints (TMJ). This can lead to jaw pain, clicking or popping in the jaw, and even chronic headaches. |
| • |
Tooth Wear and Damage: An improper bite can cause your teeth to wear down unevenly. This is because certain teeth are taking on more force than they should. This uneven wear can lead to cracks, chips, and even tooth loss over time. |
| • |
Breathing Issues: In some cases, a severe underbite can contribute to sleep apnea, a condition where you stop breathing for short periods during sleep. This is because the jaw position can affect the airway. |
| • |
Low Self-Esteem: While not a physical problem, the appearance of an underbite can definitely affect your self-esteem and confidence. This is a valid concern that shouldn't be dismissed. |
When is Underbite Surgery Needed?
Not all underbites require surgery. Mild cases can sometimes be corrected with braces or clear aligners. However, when the underbite is severe and related to the jaw bone structure itself, underbite surgery, also known as orthognathic surgery, might be the best option.
Orthognathic surgery involves repositioning the jawbones to create a more balanced and functional bite. This surgery is typically performed by an oral and maxillofacial surgeon, often in conjunction with orthodontic treatment. The surgeon will carefully plan the procedure using advanced imaging techniques to ensure the best possible outcome.
What to Expect
If underbite surgery is recommended, your dentist or orthodontist will work closely with an oral surgeon to develop a treatment plan that's right for you. The process usually involves braces before and after the surgery to align your teeth properly. The surgery itself is performed in a hospital setting, and you'll need some time to recover afterward. While recovery can take several weeks, the long-term benefits of improved function, comfort, and appearance are often well worth it.
Is It Right for You?
Ultimately, the decision to pursue underbite surgery is a personal one. If you're concerned about your underbite and the potential problems it could cause, talk to your dentist. They can evaluate your situation, discuss your options, and help you make an informed decision about the best course of treatment for your individual needs. |
