Have you ever noticed your lower teeth sitting in front of your upper teeth when you bite down? That’s called an underbite—and while it might seem like just a cosmetic quirk, it can actually affect your dental health, jaw health, speech, chewing, and confidence over time.
Many people in Zionsville and the surrounding Indianapolis area don’t realize they have an underbite—or that it can be corrected with modern orthodontic treatment, often without surgery. Whether you’ve been told your child has an underbite or you’ve noticed one in your own smile, this article will walk you through everything you need to know: what causes an underbite, why it matters, and the most effective ways to treat it, including options like clear aligners.
If you’re looking for answers, you’re in the right place—because understanding your bite is the first step toward improving it.
What is an Underbite?
An underbite is a type of malocclusion (misaligned bite) where the lower front teeth are too far forward compared with the upper front teeth. In other words, the bottom teeth or bottom jaw sits in front of the top teeth or top jaw. While some underbite cases are mild, more complex or severe underbites can impact your bite, jaw function, facial aesthetics, and long-term oral health.

What Causes an Underbite?
There are several possible causes for an underbite, including:
- Genetics – Underbite can be inherited. If your parents or grandparents have one, you may also.
- Tooth Misalignment – Sometimes teeth erupt in a way that causes the lower ones to sit in front of the uppers. This can be due to eruption, crowding, missing teeth, or other dental issues.
- Insufficient Upper Jaw Growth – An upper jaw (maxilla) that does not grow forward enough can lead to an underbite.
- Excessive Lower jaw Growth – A lower jaw (mandible) that grows more than the upper jaw (maxilla) can result in an underbite.
Regardless of the cause, underbites should be evaluated by an orthodontist to determine whether treatment is needed.
Why Is an Underbite a Problem?
Even a mild underbite can affect your bite function. More serious underbites can lead to:
- Difficulty biting and chewing
- Jaw Joint (TMJ) pain: Over time, an untreated underbite can strain the jaw joints.
- Tooth wear or chipping
- Speech challenges
- Changes to your facial profile

How is an Underbite Treated?
The good news is that underbite correction is very possible, and there are now modern treatment options. Age and severity of the underbite both play roles in how underbites can be addressed. Common solutions include:
In Children and Teens:
- Retainer – In mild underbites that are caused by teeth that meet but cause shifting of the jaw, sometimes treatment may be as simple as a retainer with a bite ramp to help guide erupting teeth in young children.
- Orthopedic Appliances – Growth guiding appliances (such as expanders and reverse-pull headgear) can guide jaw growth while children are still actively growing.
- Braces or Clear Aligners – These can shift and reposition the teeth.
- Elastics (Rubber Bands) – Often used with braces or aligners to improve bite alignment.
In Adults:
- Braces or Clear Aligners – These can help by repositioning the teeth.
- Elastics (Rubber Bands) – Often used with braces or aligners to improve bite alignment.
- Bite Correcting Appliances – Can be used to shift the bite. Often used in conjunction with braces or aligners.
- Tooth Removal – If jaws are fully formed, teeth can often still be shifted into alignment. Tooth extraction may be required to provide space to correct the positioning of the teeth and bite.
- Jaw Surgery (Orthognathic Surgery) – For severe skeletal (jaw related) underbites in adults, surgery may be necessary to reposition the jaw.
Every case is different, so a consultation with an orthodontist is essential to find the best path forward.
FAQs About Underbite
Q: Can you fix an underbite without surgery?
A: Yes — especially in children and teens, or in mild to moderate adult cases. Braces, clear aligners, and orthopedic appliances can often correct the issue without surgery. However, severe jaw misalignments in adults may require a surgical approach.
Q: What age is best to treat an underbite?
A: Typically, underbite treatment begins between ages 7–10 while the jaw is still growing. This also helps prevent toothwear, as this is the age children have permanent teeth erupted. Treatment can be successful at any age, especially with modern orthodontic techniques, and when planned by a Board Certified Orthodontist.
Q: How long does it take to fix an underbite?
A: Treatment time varies depending on severity and methods used for correction. Orthodontic correction may take 6 to 12 months in young children, and may take up to 24 months in teens and adults, on average. Cases requiring surgery often involve a longer timeline.
Q: Can adults get underbite treatment?
Absolutely! Treatment of an underbite can be successful at ANY age when planned by a Board Certified Orthodontist. Even if options may be more limited when it comes to jaw growth, braces and clear aligners can be great options for moving teeth and improving your overall bite. In mature adults with more complex underbites, treatment may require tooth removal or a bite correcting device.
