Can Braces Fix an Overbite, Underbite, or Crossbite?
Yes — braces correct the large majority of overbites, underbites and crossbites, often on their own and sometimes with a supporting appliance like an expander, elastics or temporary anchorage devices. Most bite correction takes roughly 12 to 24 months as part of comprehensive treatment.
The important distinction is whether the problem is dental or skeletal. When teeth are simply positioned wrong, braces solve it. When the jaws themselves are mismatched in size or position, treatment either guides growth (in children) or, in significant adult cases, combines braces with jaw surgery.
Here is what each bite problem is, what correcting it typically involves, and how to tell which category you are in.
What Is an Overbite, and How Do Braces Fix It?
An overbite is vertical overlap: the upper front teeth cover too much of the lower front teeth. A small amount of overlap is normal and healthy. A deep overbite can wear down the lower teeth, irritate the palate and, over years, contribute to jaw discomfort.
Dental overbite
If the overlap comes from tooth position, braces handle it directly — intruding the front teeth, leveling the bite and sometimes using elastics to bring the arches into a better relationship. Most cases resolve within 12 to 24 months.
Skeletal overbite
If the lower jaw is set back relative to the upper jaw, the correction depends on age. In a growing child, functional appliances or headgear can encourage the lower jaw forward while growth is still available. In an adult whose growth is finished, braces can camouflage a mild to moderate discrepancy; a severe one may need orthognathic surgery.
Can Braces Fix an Underbite?
Often, yes — and timing matters more here than with any other bite problem. An underbite means the lower teeth sit in front of the upper teeth when you bite down. It can be dental (tipped teeth) or skeletal (a lower jaw that has outgrown the upper jaw, or an underdeveloped upper jaw).
In children
This is why the American Association of Orthodontists recommends an orthodontic screening around age seven. In a young child, a palatal expander and a facemask can encourage the upper jaw forward and correct a developing underbite while the sutures are still responsive — results that are simply not available later. That is the core of Phase 1 early treatment.
In adults
Mild underbites can be camouflaged with braces and elastics. A significant skeletal underbite in an adult usually requires braces plus jaw surgery, with the full process running about 18 to 36 months including pre-surgical alignment and post-surgical finishing. It is a bigger commitment, and it produces changes braces alone cannot.
Can Braces Fix a Crossbite?
Yes. A crossbite means one or more upper teeth sit inside the lower teeth instead of outside them. It can affect the front teeth (anterior) or the back teeth (posterior), on one side or both.
- Mild dental crossbites often correct in 12 to 18 months with braces alone
- Posterior crossbites caused by a narrow upper jaw usually need an expander first, then braces
- Expansion works best in children and adolescents while the palatal suture is still adaptable
- Adults with a narrow jaw may need surgically assisted expansion or a different approach
- Untreated crossbites can cause uneven wear, gum recession and a shifted jaw position over time
Children with a crossbite sometimes shift the jaw to one side to bite comfortably. Left alone, that functional shift can become structural, which is one of the strongest arguments for an early screening.
How Long Does Bite Correction Take?
| Bite problem | Typical approach | Typical timeline |
|---|---|---|
| Mild dental overbite | Braces, sometimes with elastics | 12 – 18 months |
| Deep or skeletal overbite | Braces + functional appliance or elastics; surgery in severe adult cases | 18 – 24+ months |
| Underbite in a growing child | Expander + facemask, then braces | Phase 1 about 9 – 18 months, plus later treatment |
| Significant adult underbite | Braces + orthognathic surgery | 18 – 36 months total |
| Anterior crossbite | Braces, sometimes with an appliance | 12 – 18 months |
| Posterior crossbite | Expander, then braces | 12 – 24 months |
Timelines assume consistent wear of elastics or appliances. Missed appointments and inconsistent elastic wear are the two most common reasons a case runs long.
Can Invisalign Correct Bite Problems Too?
Clear aligners have improved substantially at bite correction and can handle many mild to moderate overbites, some crossbites and select underbites, usually with attachments and elastics. What aligners do less predictably is large vertical movement and significant skeletal correction.
In our practice we choose the tool that fits the case rather than the other way around. If Invisalign will get you there, we will say so; if braces will do it faster or more predictably, we will say that too. Our comparison of Invisalign and braces walks through the trade-offs.
What Does a Bite Evaluation Involve?
Diagnosing a bite takes records, not a glance. At your first visit we take digital photos and X-rays and complete a thorough exam, then review what the images show with you. The X-rays are what reveal whether the jaws are mismatched skeletally, where the roots sit, and whether any permanent teeth are impacted or missing — none of which is visible from the outside.
The digital scan replaces the old putty impressions entirely. Our iTero scanner builds a precise 3D model of your bite in a few minutes with no goop and no gagging, which matters if you have a strong gag reflex or a nervous child in the chair. That model becomes the basis for the treatment simulation we walk you through.
From there you get options, a timeline and a fee, including any insurance benefit you have. If treatment should wait — and for many younger children it should — we say so and monitor instead.
What Happens If a Bite Problem Goes Untreated?
Bite problems are not purely cosmetic. Over years, an uncorrected bite can lead to uneven enamel wear, chipped or fractured teeth, gum recession on teeth taking excess force, difficulty chewing, speech effects in children, and jaw joint discomfort. Underbites and crossbites can also affect facial development in a growing child.
None of that is a reason to panic — it is a reason to get an evaluation and know where you stand. Some bites are monitored rather than treated, which is exactly what our Growth Guidance program does for younger patients: periodic checkups at no charge while we watch tooth eruption and jaw growth.
Frequently Asked Questions
Can braces fix an overbite without surgery?
Most of the time, yes. Overbites caused by tooth position respond to braces alone, and mild to moderate skeletal overbites can often be camouflaged with braces and elastics. Surgery is generally reserved for severe skeletal discrepancies in patients whose growth is complete.
What age is best to fix an underbite?
Around ages 7 to 10 is ideal for a skeletal underbite, because an expander and facemask can influence upper jaw growth while the sutures are still responsive. Waiting until the teen years or adulthood narrows the options and makes surgery more likely for significant cases.
Can adults fix a crossbite with braces?
Yes for dental crossbites and many mild skeletal ones. A narrow upper jaw in an adult may need surgically assisted expansion, since the palatal suture has fused. An exam with records is the only way to tell which situation applies.
How do I know if my bite problem is dental or skeletal?
You cannot tell reliably by looking. It takes an orthodontic exam with X-rays and digital records to see the relationship between the jaws and the position of the roots. That assessment is part of your free consult here.
Will my bite relapse after braces?
It can if retainers are not worn. Corrected bites, especially deep bites and crossbites, have a tendency to drift back. Consistent retainer wear on the schedule we give you is what keeps the correction stable.
Do elastics really matter for bite correction?
Enormously. Elastics apply the forces that move one arch relative to the other, and they only work when they are in the mouth. Inconsistent elastic wear is one of the most common reasons bite correction takes longer than planned.
Will Correcting Your Bite Change How You Look?
Sometimes, and usually for the better. Correcting a deep overbite can open up the lower third of the face slightly. Expanding a narrow upper jaw broadens the smile so fewer dark corners show at the edges. Underbite correction in a growing child supports more balanced facial development, and surgical correction in an adult changes the jaw profile noticeably by design.
Most bite correction, though, is about function first: even wear across your teeth, comfortable chewing, and forces distributed the way the joints and gums are built to handle. The cosmetic improvement tends to come along for the ride. During your consult we can show you a simulation of the projected result so you know what you are working toward.
