Overbite and Underbite Fixes: Your Options Explained
How overbites and underbites are corrected in teens and adults, from braces and aligners to jaw surgery, with honest cost ranges and what decides which fix you need.
You have noticed that your top teeth sit well in front of your bottom ones, or the other way round. Perhaps a dentist mentioned it in passing, perhaps your jaw aches after meals, or perhaps you simply dislike how your profile looks in photos.
Bite problems are common, and most of them are fixable. The right fix depends on one key question: is the problem in the teeth, or in the jaws themselves? A bite caused by tilted teeth can usually be corrected with braces or aligners. A bite caused by jaws that grew at different rates sometimes needs more.
This guide explains the difference, the treatment options for each, what they cost, and how to tell what you are dealing with.
Overbite, Overjet and Underbite: The Terms
Dentists use a few related words, and knowing them makes a consultation far easier to follow.
- Overbite is how far your upper front teeth overlap your lower front teeth vertically. A small overlap is normal. A deep bite is when the upper teeth cover most or all of the lower teeth, sometimes so far that the lower teeth bite into the gum behind the upper ones.
- Overjet is how far the upper front teeth stick out horizontally in front of the lower ones. This is what most people mean when they say "buck teeth".
- Underbite, sometimes called a Class III bite, is when the lower front teeth sit in front of the upper front teeth when you close.
- Crossbite is when some upper teeth sit inside the lower ones, either at the front or the side.
You can have more than one at once. A crowded mouth with a deep bite is a very common combination.
Why Fixing Your Bite Is About More Than Looks
A bite that does not line up is not only cosmetic. Over years, it can cause:
- Uneven wear, where teeth that hit too hard or at the wrong angle chip, flatten or crack.
- Gum damage, especially with a deep bite where lower teeth press into the palate.
- Jaw discomfort. Some people with bite problems also have aching jaw muscles, though the link is not straightforward and many people with uneven bites have no pain at all.
- Difficulty biting or chewing certain foods, or speech issues with some sounds.
None of this is an emergency. But it is a reason to get an assessment rather than putting it off indefinitely.
Dental or Skeletal: The Question That Decides Everything
A dental bite problem is when the jaws are roughly in proportion but the teeth are tipped forward or back. Moving the teeth fixes it.
A skeletal bite problem is when the upper and lower jaw are different sizes or positions. Teeth can be tilted to compensate, sometimes very successfully, but there is a limit to how far that can go.
Your dentist or orthodontist works this out from an exam, photos, and usually a side-on x-ray of the skull that shows how the jaws relate. That is why a proper consultation, rather than a remote photo assessment, matters for bite problems in particular.
Treatment Options Compared
| Treatment | What it corrects | Typical US cost | Typical time | Notes |
|---|---|---|---|---|
| Comprehensive Invisalign | Many dental overbites and mild underbites | $4,000 to $8,000 | 12 to 24 months | Uses elastics and attachments for bite changes |
| Traditional metal braces | Dental overbites, underbites, crossbites | $3,000 to $7,000 | Usually a year or longer | Most versatile, works for complex movement |
| Ceramic braces | Same as metal braces | $4,000 to $8,000 | Similar to metal | Less visible, slightly more fragile |
| Growth appliances in children | Skeletal problems while the jaw is still growing | Usually part of the orthodontic fee | Months, often before braces | Only works before growth ends |
| Braces plus jaw surgery | Significant skeletal problems in adults | Varies widely, quoted separately | Often two years or more overall | Usually hospital-based, may be partly covered by medical insurance |
These figures are ranges, not quotes. Location, the complexity of the bite, and what is included all move the price. Mail-order aligners are not in the table on purpose: they are designed for mild cosmetic crowding, not bite correction. For your own numbers, the aligners vs braces comparison tool gives ranges and timelines based on how complex your case is.
Fixing an Overbite
With Braces
Braces correct a dental overbite by moving the upper front teeth back, the lower front teeth forward, or both, and by adjusting how deep the overlap is. Elastics, small rubber bands hooked between upper and lower brackets, do much of the work of pulling the bite into line. Wearing them as instructed is the single biggest factor in how fast an overbite corrects.
With Aligners
Clear aligners can also correct many overbites, using attachments on the teeth and elastics hooked onto the trays. They work best for mild to moderate dental overbites. Very deep bites or large overjets can be harder to control with trays alone, so do not be surprised if an orthodontist recommends braces for yours. Our guide to clear aligners vs braces explains where each tends to perform better.
Sometimes, Removing Teeth
When there is not enough room to pull protruding upper teeth back, the plan may include removing two premolars to create space. This is less common than it once was, but still sensible in some cases.
Fixing an Underbite
Underbites are more often skeletal than overbites, which makes the approach depend heavily on age.
In children, an underbite caught early can sometimes be guided with appliances that encourage the upper jaw to grow forward. This is why dentists suggest an orthodontic check around age seven, when problems with jaw growth are easier to influence.
In teens and adults with a mild dental underbite, braces or aligners can tip the lower teeth back and upper teeth forward to bring them into a normal overlap.
In adults with a significant skeletal underbite, the honest answer is that teeth alone often cannot fix it. The usual approach is orthognathic surgery, an operation that repositions one or both jaws, combined with braces before and after. It is a major undertaking with weeks of recovery, but for the right person it can transform both function and appearance. Because it treats the jaw itself, part of it is sometimes covered by medical rather than dental insurance.
What About Veneers?
Veneers can make teeth look more even from the front, but they cannot change where the jaws meet. Using them to disguise a bite problem can put extra force on the veneers and lead to chips and failures. If your bite is the issue, fix the bite first and consider cosmetic work afterward.
What Treatment Feels Like
Expect pressure and tenderness for a few days when braces are first fitted, when wires are adjusted, and when elastics are introduced. Aligners cause a similar ache for a day or two with each new tray. Soft foods and over-the-counter pain relief usually help. Your bite may feel strange partway through treatment as teeth pass through awkward positions, and that is normal.
After treatment, you will need a retainer, a device that holds your teeth in their new position. Bites that have been corrected can drift back without one, so most people wear a retainer at night for the long term.
Signs Your Bite May Need Attention
You do not need to measure anything yourself, but a few everyday clues suggest it is worth asking about your bite at your next visit:
- Your lower front teeth disappear completely behind your upper ones when you close.
- You can see the lower front teeth in front of the upper ones when you bite together.
- The edges of your front teeth look chipped, flat or worn, especially if you are relatively young.
- You bite your cheek or the roof of your mouth regularly.
- Your jaw clicks, aches or tires after chewing, or you notice you clench or grind.
- Biting into a sandwich with your front teeth is awkward, so you tear food with your side teeth instead.
None of these confirm a problem on their own, and plenty of people with a slightly uneven bite never need treatment. They are simply useful things to mention, because they help the dentist decide whether a closer look is worthwhile. If grinding is part of the picture, our guide to teeth grinding signs and fixes explains how it is managed alongside bite treatment.
Choosing Between Your Options
Once you know what kind of bite problem you have, a few practical questions narrow the choice:
- How severe is it? Mild dental problems leave you with the most choice. Severe skeletal problems narrow it to braces, sometimes with surgery.
- How disciplined will you be? Aligners and elastics only work when worn. If you know you would leave trays in a drawer, fixed braces protect you from yourself.
- How visible can treatment be? Ceramic braces and aligners are less noticeable than metal, though they cost more.
- How long can you commit? Bite correction is rarely quick. Ask for a realistic timeline, not a best case.
- What does the fee include? Elastics, refinements, retainers and emergency visits can add up if they are charged separately.
It is reasonable to get two opinions for a bite problem, particularly if surgery is suggested or if one practice recommends aligners while another recommends braces. Differences in approach are common, and hearing both explanations helps you understand your own case.
Frequently Asked Questions
Can an overbite be fixed without braces? Many dental overbites can be corrected with clear aligners instead of fixed braces. Very deep bites or large overjets are sometimes harder to control with trays, so the right choice depends on the severity. Veneers do not fix the bite itself.
Can adults fix an underbite without surgery? If the underbite comes mainly from tilted teeth, braces or aligners can often correct it. If the lower jaw is significantly larger or further forward than the upper jaw, surgery combined with braces is usually the only way to fully correct it. An orthodontist can tell you which applies after an exam and x-rays.
How long does it take to fix an overbite? Mild cases can sometimes be corrected within a year, while complex cases often take 18 to 24 months. Wearing elastics consistently makes a large difference. Your orthodontist will give you an estimate once they have assessed your bite.
Is a slight overbite normal? Yes. A small vertical overlap of the upper teeth over the lower is the normal, healthy bite. It only becomes a concern when the overlap is deep enough to cause wear, gum damage or discomfort.
Does insurance cover overbite treatment? Some dental plans include orthodontic benefits, often with a lifetime maximum and sometimes only for children. Jaw surgery may fall partly under medical insurance when it corrects a functional problem. Check both plans before treatment starts.
What to Do Next
Book an orthodontic consultation and ask specifically whether your bite problem is dental, skeletal or a mix of the two, because that answer shapes everything else. If you have dental insurance, run your plan through the dental insurance estimator before the appointment so you know what your orthodontic benefit is likely to cover. Then compare the treatment plans you are offered on what they correct, how long they take and what is included in the fee.
