An overbite is one of the most common bite issues, affecting kids, teens, and adults alike. In simple terms, it’s when your upper front teeth overlap your lower front teeth more than they should. A small overlap is normal. A larger one can wear down enamel, strain your jaw, and change how you feel about your smile.
Modern orthodontics offers more ways to correct an overbite than ever, from clear aligners through to jaw surgery in the most severe cases. This guide walks you through the options, how long each tends to take, and how to choose the right care.
The best treatment always depends on the type and severity of your overbite, which is why a professional evaluation matters so much.
Understanding Overbite: Types and Severity
Before you can pick a treatment, it helps to understand what you’re actually dealing with. Not every overlap is the same, and an overbite is a different problem from an underbite, where the lower teeth sit in front of the upper ones.
Overbite versus overjet. An overbite is vertical, meaning your top teeth cover part of your bottom teeth when you close your mouth. An overjet is horizontal, where the top teeth stick out past the bottom teeth. People often confuse the two, and they can call for different approaches.
Severity. Orthodontists generally group overbites into three ranges:
- Normal. About 1 to 3 mm of overlap.
- Moderate. Roughly 4 to 6 mm.
- Severe, sometimes called a deep bite. More than 6 mm, often with the lower teeth biting into the gum tissue behind the upper teeth.
Dental versus skeletal. A dental overbite means the teeth are tipped or positioned incorrectly while the jaws themselves are fine. A skeletal overbite means the upper and lower jaws don’t line up. That distinction matters enormously, because dental cases can usually be corrected with braces or clear aligners, while skeletal cases may need jaw surgery.
Class II malocclusion. This is the clinical term for a bite where the upper jaw and teeth sit noticeably ahead of the lower jaw. It’s the category most overbite cases fall into.
If you’re unsure which type you have, that’s completely normal. A quick exam and digital scans sort it out fast.
Causes and Health Risks of an Untreated Overbite
Most overbites come from a mix of genetics and habits. Knowing the cause helps you understand the options.
Common causes:
- Genetics. Jaw shape and size are inherited, and plenty of overbites simply run in families.
- Childhood habits. Extended thumb sucking, pacifier use past age three, or tongue thrusting can push the upper teeth forward or hold the lower jaw back.
- Missing or crowded teeth. Losing baby teeth too early or having crowded adult teeth can shift the bite.
- Jaw development differences. Uneven growth between the upper and lower jaws creates a skeletal overbite.
What can happen if it goes untreated:
- Uneven tooth wear and chipped enamel
- Jaw pain, headaches, and TMJ issues
- Gum recession from the lower teeth biting into the palate
- Speech difficulties, especially with certain sounds
- Breathing and sleep concerns, including snoring in some cases
- Self-consciousness that affects confidence in social and work settings
An overbite doesn’t just affect how your smile looks. It shapes how your mouth functions for decades to come.
Non-Surgical Overbite Treatment Options
Most overbites can be corrected without surgery. Here’s a look at the main choices we use every day.
Modern Metal Braces
Metal braces are still one of the most reliable ways to correct an overbite. They’re smaller and smoother than what many parents remember, and they work well for moderate to complex cases including deep bites. Braces give the orthodontist full control over each tooth, which is especially useful when the bite needs major repositioning.
Clear Braces
Clear braces work just like metal ones but use tooth-colored brackets that blend in. They’re a popular pick for teens and adults who want the strength of braces with a lower profile look.
Clear Aligners
Clear aligners are a good fit for mild to moderate overbites. You wear a series of custom trays that gradually shift your teeth into place, and they come out for eating and brushing. Digital scans replace the messy impressions people remember. For deeper bites, attachments and small elastics let the aligners do more.
Palate Expanders and Functional Appliances
For growing kids, appliances like palate expanders can guide jaw growth so the bite comes together properly. This is where treating a child early makes the biggest difference, because you can influence how the jaws develop instead of only moving teeth once they’re set.
Tooth Extraction as an Add-On
In some cases, removing one or two teeth creates the space needed to bring the bite into alignment. It isn’t a first choice, but it can be a sensible part of the plan when crowding is severe.
Surgical Treatment for Severe Overbites
When an overbite comes from a true difference in jaw size or position, braces or aligners alone can’t fix it. That’s when orthognathic surgery becomes part of the conversation.
When it’s needed. Adults with a skeletal Class II bite, where the lower jaw sits significantly back or the upper jaw sits too far forward, may benefit from surgery. Growing teens sometimes avoid it because their jaws are still developing and can still be guided.
How it works. An oral and maxillofacial surgeon repositions the upper jaw, the lower jaw, or both. Braces or aligners are used before and after so the teeth fit together correctly once the jaws are moved.
Recovery. Most patients take a few weeks away from work or school. Swelling and a soft food diet are typical during early healing, and full results come together over several months.
What it achieves. Better chewing, easier breathing, less jaw strain, and a more balanced facial profile. It’s a bigger commitment, but for the right case the difference is significant.

Overbite Treatment by Age
Age shapes what’s possible and what’s most efficient. We treat patients at every stage of life, and the approach shifts as growth does.
Children. The American Association of Orthodontists recommends a first orthodontic check by age 7. At this stage, treatment can guide jaw growth using expanders or functional appliances, which often reduces the need for more involved care later.
Teens. This is a sweet spot for braces or clear aligners. Growth is still on your side and treatment tends to move efficiently. Teens often lean toward clear aligners or clear braces for the look, though modern metal braces remain a strong option.
Adults. You’re never too old for a better bite. Adults typically use clear aligners, clear braces, or modern metal braces. If the overbite is skeletal, surgery combined with orthodontic treatment may be recommended.
How Long Overbite Treatment Takes
Timelines vary with severity, age, and the approach used, but here is the general shape of it.
- Mild dental overbites. Often correct in around a year, sometimes less with clear aligners.
- Moderate cases. Typically run somewhere between 18 and 24 months.
- Complex and deep bites. Can extend toward three years, depending on how much the bite has to change.
- Surgical cases. Involve orthodontic work before and after the procedure, so the full course usually spans two to three years.
Retainer wear afterward is what keeps the result, and that part is ongoing rather than a phase you finish.
Choosing the Right Orthodontist
Overbite correction is a real commitment, so the provider you pick matters. Here’s a quick checklist to guide your search.
- Specialty training. Look for an orthodontist rather than a general dentist offering aligners. Orthodontists complete years of additional training focused specifically on tooth movement and bite correction.
- Experience with your case type. Ask how often they treat overbites at your severity level, including surgical coordination if that’s likely.
- Modern technology. Digital scans, digital X-rays, and 3D treatment planning make care more accurate and more comfortable.
- Questions worth asking. What type of overbite do I have, dental or skeletal? Which options would work, and which do you recommend? How long is treatment likely to take? What happens if I need refinements at the end?
- Red flags. Extreme pressure to decide the same day, promises that sound too good to be true, or a plan that skips X-rays and a full exam.
A consultation should feel calm, informative, and yours to think over.
Frequently Asked Questions
Can an overbite fix itself without treatment?
No, overbites don’t correct on their own, especially in adults. In children, jaw growth can sometimes help mild cases, but professional guidance is still the safest way to make sure the bite develops properly.
How long does overbite correction take?
Most cases run 12 to 36 months depending on severity, age, and the treatment used. Clear aligners often work faster for mild cases, while braces and surgical cases take longer.
Are clear aligners effective for an overbite?
Yes, clear aligners work well for many mild to moderate overbites. With attachments and elastics they can handle some deeper bites too. Severe skeletal overbites may still need braces or surgery.
What is the fastest way to fix an overbite?
Speed depends on the case. Mild dental overbites may respond quickly to clear aligners, while moderate cases usually need 18 to 24 months. There’s no real shortcut for skeletal correction.
Do retainers prevent an overbite from returning?
Yes. Retainers are what make your results last. Teeth naturally want to shift over time, and consistent retainer wear keeps your new bite stable.
Your Next Step
The right overbite treatment depends on your age, the type of overbite, and your goals. Some smiles need only clear aligners. Others do best with modern metal braces or clear braces. A smaller group benefits from jaw surgery combined with orthodontic treatment. What every case shares is that a professional evaluation is the starting point.
Today’s care is more comfortable, more accurate, and more flexible than it used to be. Parents weighing early treatment for a child and adults finally ready to do something about their bite both have the same clear first move.
