If you’ve recently been told you or your child has an underbite, one of the first questions that probably comes to mind is: Do braces fix an underbite?
The short answer is yes. Braces can successfully correct many underbites. However, the cause of the underbite determines whether they’re the best option.
We often see patients assume that every underbite requires the same treatment, but that’s rarely the case. Some underbites are caused primarily by the position of the teeth, while others involve the way the upper and lower jaws developed.
Understanding that difference is one of the most important steps in creating the right treatment plan.
What Is an Underbite?
An underbite is a type of bite misalignment where your lower teeth sit in front of the upper teeth when you close your mouth.
Depending on how pronounced it is, an underbite can range from barely noticeable to more significant.
Besides affecting how your smile looks, an underbite potentially makes it more difficult to bite and chew comfortably. Over time, it can cause uneven tooth wear, jaw discomfort, or speech challenges for some patients.
Several signs may indicate an underbite, including:
- Lower teeth extending beyond the upper teeth
- Difficulty biting or chewing certain foods
- Speech differences or pronunciation challenges
- Uneven wear on the teeth
- Jaw discomfort or strain
One question patients frequently ask is why underbites happen in the first place. The answer depends on several different factors.
What Causes an Underbite?
Underbites usually develop because of the way the teeth, jaws, or both grow over time.
In many cases, genetics play the biggest role. If one or both parents have an underbite or other bite alignment concerns, their children may be more likely to develop one as well.
Jaw development is another common factor. Sometimes the lower jaw grows more prominently than the upper jaw, creating the appearance of an underbite even when the teeth themselves are healthy.
Certain childhood habits, like thumb sucking, or developmental conditions can contribute in some cases, although these are generally less common than inherited growth patterns.
Dental Underbites vs. Skeletal Underbites
One important factor orthodontists evaluate is whether an underbite is dental or skeletal.
A dental underbite occurs when the teeth themselves are positioned incorrectly while the jaws are generally aligned. These cases are often excellent candidates for orthodontic treatment with braces or clear aligners.
A skeletal underbite involves the position or size of the upper and lower jaws. If the jawbones themselves are misaligned, braces alone may not fully correct the bite.
During your consultation, we’ll carefully evaluate your bite, jaw development, and overall smile before recommending the treatment approach that’s best for you.
Do Braces Fix an Underbite?
For many patients, the answer is yes. Braces are very effective at correcting mild to moderate dental underbites by gradually moving teeth into healthier alignment.
As your teeth shift over time, your bite improves, making it easier to chew comfortably while creating a more balanced smile.
Braces can also work alongside other orthodontic appliances, such as elastics, to improve how the upper and lower teeth fit together throughout treatment.
Braces may be recommended when:
- The underbite is primarily caused by tooth positioning
- Jaw growth is still developing
- Tooth alignment contributes significantly to the bite problem
- The goal is improving bite function and smile alignment
In our experience, many patients are surprised to learn that braces do more than straighten your teeth. They often improve how your teeth work together, which can support both comfort and long-term oral health.
When Do Underbites Need More Than Braces?
If an underbite is caused primarily by jaw structure rather than tooth position, additional treatment may be recommended.
For younger patients who are still growing, orthodontists may use specialized appliances to help guide jaw development before or alongside braces. Early treatment can sometimes reduce the severity of future bite concerns by taking advantage of natural growth.
Adults with significant skeletal underbites may occasionally benefit from a combination of braces and orthognathic (jaw) surgery.
While surgery often sounds intimidating, it’s typically recommended only when it offers the most predictable way to create a healthy, functional bite.
Here’s what we recommend: rather than focusing on whether braces or surgery is “better,” focus on receiving a personalized diagnosis. The right treatment is the one that addresses the underlying cause of your underbite.
What to Expect During Underbite Treatment
Every underbite treatment begins with a comprehensive orthodontic evaluation.
During your consultation, we’ll examine your bite, take digital images and X-rays when needed, and evaluate how your teeth and jaws work together.
This information allows us to create a treatment plan that’s tailored specifically to your smile.
As treatment progresses, regular appointments help us monitor your progress and make adjustments as needed. Depending on your treatment plan, you may also wear elastics or other orthodontic appliances to help correct your bite.
During treatment, your orthodontic team may monitor:
- Bite improvement
- Tooth movement
- Jaw alignment
- Overall treatment progress
- Long-term stability
Our goal is to help you achieve a healthy bite and a smile that functions as beautifully as it looks.
The Best Way to Find the Right Underbite Treatment
So, do braces fix an underbite? In many cases, yes. But not every underbite is the same. The most effective treatment depends on whether the issue involves the teeth, the jaws, or both.
We often tell patients that the best treatment plan starts with understanding why the underbite developed in the first place. Once that question is answered, recommending the right solution becomes much more straightforward.
If you’re concerned about an underbite for yourself or your child, scheduling an orthodontic consultation is the best next step.
At Orthobar, we’ll take the time to evaluate your bite, explain your options clearly, and help you build a treatment plan that’s tailored to your smile, goals, and long-term oral health.
