An overbite can affect more than the look of your smile: a deep bite may contribute to tooth wear, discomfort or difficulty biting. How to fix an overbite in adults depends on its cause and severity, but treatment commonly uses braces or clear aligners to move teeth into a better position; severe jaw-related cases may need surgery alongside orthodontic treatment.
If you’re concerned about how your teeth meet, you may wonder how to fix an overbite in adults and whether treatment differs from treatment for children. A mild overbite doesn’t always cause problems, but an uneven bite can affect comfort and dental health.
This guide explains what an overbite is, what may cause it and how it can affect your teeth, jaw and smile. You’ll also learn how adult treatment options work and how they differ from treatment while a child’s jaw is still growing.
Key Takeaways
- Adult overbite correction may involve braces or clear aligners, with the approach shaped by the bite and the tooth movements needed.
- Children’s growing jaws can affect treatment timing; in the UK, under-18s might receive NHS treatment for free if their overbite is severe enough.
- Inherited jaw and tooth patterns, childhood habits and grinding can all contribute to an overbite.
- Notice how your bite affects chewing, tooth wear or jaw comfort to help decide when to discuss an assessment with a dental professional.
Adult treatment compared with children’s treatment
Children’s orthodontic treatment can use jaw growth to guide how the teeth meet. Treatment often starts between ages 10 and 14, whilst the jaw is still growing. For adults, growth has finished, so orthodontic treatment focuses on moving teeth and correcting their overlap. Learning how to fix an overbite in adults starts with considering tooth position, jaw alignment and oral health.
In the UK, under-18s might receive NHS treatment for free if their overbite is severe enough, according to the NHS. That age-based statement does not establish adult eligibility. A dentist can assess the bite, teeth and gums, then discuss whether treatment addresses a clinical concern or is primarily cosmetic.
Look beyond appearance when deciding whether to seek advice. Upper front teeth that cover the lower teeth deeply may make biting uncomfortable, while uneven wear or chipped edges can signal strain. Jaw pain, difficulty chewing, teeth pressing into the palate or trouble cleaning crowded teeth are also reasons to discuss your bite with a dentist.
Children may be referred for orthodontic treatment while their jaws are developing, but adults can still benefit from tooth movement. An assessment considers the degree of overlap, bite function and oral health. A mild overbite without discomfort or damage may need monitoring rather than correction; increasing wear or recurring pain deserves attention.
Can the NHS provide overbite treatment for adults, and what are the eligibility rules? The NHS fact applies to under-18s with a sufficiently severe overbite; it does not set adult eligibility. A dentist can explain how to fix an overbite in adults by assessing clinical need and discussing suitable care. If your bite affects eating or causes tooth damage, arrange a dental assessment to discuss your concerns.

Causes of an overbite
An overbite can develop because of inherited traits, jaw growth, tooth eruption or childhood habits. These influences shape how the upper and lower teeth meet. A person may inherit a jaw or tooth pattern that runs in their family, affecting where the front teeth sit as permanent teeth emerge.
Jaw development matters too. If the upper or lower jaw grows out of alignment, the teeth may overlap more than expected. Tooth eruption also plays a role: the position and spacing of emerging teeth can affect the bite. Several factors may combine, so an overbite does not always have one clear cause.
Habits during childhood can influence developing teeth. Thumb sucking or dummy use beyond early childhood may contribute to an overbite; use past age 3 is one possible factor. Tongue thrusting, where the tongue presses against the teeth, can also affect their position over time. These habits don’t mean every child will develop the same bite.
Teeth grinding is another possible contributor. Repeated pressure can change how teeth meet, while jaw growth and tooth position may also shape the overlap. For instance, someone may inherit a particular jaw pattern and also have a history of grinding. Considering several influences helps build a clearer picture of the bite.
A dentist can assess tooth alignment and may use dental X-rays to examine how the teeth fit together. The assessment can help distinguish a tooth-position concern from a jaw-growth pattern. That difference matters because treatment depends on the cause and severity: moving teeth may address some bites, while severe jaw-related cases may need a different orthodontic plan. Surgery is uncommon for deep overbites and is considered only in severe cases where braces alone cannot correct the bite.
Possible dental and facial effects
A mild overbite can be normal and cause no difficulty. The important questions are how the upper teeth meet the lower teeth and whether the overlap affects dental health or everyday function. Overbite describes vertical overlap; overjet describes how far the upper teeth project forwards. They are different features, though both can affect the appearance of a smile.
A deep bite can put extra pressure on the front teeth. Over time, this may wear down their surfaces or increase the chance of chips and cracks. In some cases, lower teeth press into the gums or palate, causing damage or discomfort. Teeth touching the roof of the mouth when biting, for example, warrant a dental assessment.
The effects can extend beyond tooth surfaces. A severe overbite may make biting into food or chewing difficult and may contribute to jaw discomfort, strain or headaches. Some people also experience speech difficulties. These symptoms can have different causes, so their presence alone does not show that the bite is responsible; for instance, clinics such as Healthy Living Hickory note that broader tension in the upper cervical spine can also contribute to persistent jaw and head discomfort.
Facial appearance and confidence may matter too. Protruding upper teeth can change how a smile looks, while uneven overlap may make some people self-conscious. Crowded teeth can also be harder to clean, creating a practical concern as well as an appearance concern. Habits such as grinding may add pressure to teeth already experiencing uneven wear.
Look for patterns rather than judging your bite from a photograph. Recurring jaw pain, difficulty chewing, chipped front teeth, uneven wear or lower teeth pressing into the palate are reasons to discuss your bite with a dentist. Report new pain, infection or loose teeth promptly rather than waiting for a routine visit. An assessment can consider tooth wear, bite function and gum health together to clarify whether the overlap needs attention.
If tooth damage or discomfort is affecting your daily life, book a dental assessment to discuss your bite and symptoms.
Dental Scotland
Dental Scotland offers Invisalign for adults considering discreet orthodontic treatment. If your overbite affects your bite, causes tooth wear or affects your confidence, a dental consultation can help determine whether aligners suit your needs. Invisalign may be an option for mild to moderate overbites; more complex bite concerns may need another approach, so treatment should be based on the teeth and jaw involved.
Composite Bonding and Veneers address cosmetic concerns, while Dental Implants replace missing teeth. These treatments have different purposes from overbite correction, but may support broader smile goals. Understanding the distinction helps you focus first on bite function, then discuss any separate aesthetic or restorative priorities.
Contact Dental Scotland to discuss your overbite and possible next steps.
Take the next step with clarity
Choosing treatment is about more than how your smile looks. Your bite, comfort and dental health matter too, so link your concern to a clear goal. You may want to ease discomfort when chewing, protect teeth from further wear or feel more confident about your smile. Naming your priority helps focus the conversation on what you want treatment to change.
Understanding how to fix an overbite in adults starts with identifying whether the concern involves tooth position, bite function or jaw alignment. An assessment brings these factors together and explains which options may suit your needs. Cosmetic treatment may support separate smile goals, but it does not correct a bite problem.
If you’re ready to discuss your concerns and possible next steps, contact Dental Scotland about your overbite. A clear conversation can help you consider a plan that reflects your priorities. You can move forward at a pace that feels right.
Frequently Asked Questions
What is an overbite?
An overbite is the vertical overlap of the upper front teeth over the lower front teeth. It’s different from an overjet, which describes how far the upper teeth project forwards. A mild overlap is normal for many people; an orthodontist may aim for a functional, aesthetic overlap of 2–4 mm. The measurement alone doesn’t show whether your bite causes a problem.
Can you realign jaws without surgery?
Braces or clear aligners can move teeth without surgery, helping improve how the upper and lower teeth meet. They do not change adult jaw growth. If a severe difference in jaw position causes the overbite, braces alone may not correct it; corrective jaw surgery may be considered alongside orthodontic treatment. The key distinction is whether the main issue involves tooth position or jaw alignment.
Does an overbite affect dental health?
It can, particularly if a deep bite repeatedly puts pressure on teeth or soft tissue. Lower teeth may press against the gums or palate, while front teeth can become worn, chipped or cracked. Chewing difficulty and jaw discomfort can also occur. An overbite does not automatically mean dental damage; uneven wear or recurring soreness can indicate why an assessment may be helpful.
What does it look like before and after?
Before treatment, the upper front teeth may noticeably overlap the lower teeth, or the bite may look deep when the mouth closes. After orthodontic treatment, the aim is a more balanced overlap and contact between the arches. For a useful comparison, look at how the teeth meet as well as how the smile looks at rest. Photos show appearance, but not bite function or tooth health.
What types of braces work for an overbite?
Fixed braces may use metal, ceramic or lingual brackets, with wires guiding tooth movement. The bracket position differs, but each type stays attached during treatment. Clear aligners, including Invisalign, are removable alternatives for some overbites. Elastics can also help coordinate the upper and lower arches. The right type depends on bite severity and the movement needed.
What questions should I ask my dentist?
Ask what is causing your overbite, whether it affects bite function, and whether the concern involves tooth position or jaw alignment. Find out which options suit your teeth and gums, what movements the treatment plan aims to make, and whether retainers will be needed afterwards. If you have pain, worn teeth or difficulty chewing, describe when it happens and which teeth feel affected.
