An overbite is one of the most common bite issues dentists see, and it is also one of the conditions people assume needs metal braces to fix. That assumption is outdated. For most mild and moderate cases, an overbite can be corrected with clear aligners, using the same gradual, staged approach that straightens crowded or gapped teeth, just applied to how your upper and lower teeth meet rather than how straight they sit individually.
This guide walks through what an overbite actually is, what causes it, how clear aligners correct it, when a different treatment is a better fit, and what the full process looks like from assessment through to a finished smile, including realistic timelines and UK pricing.
What is an overbite and what causes it
An overbite describes the amount your upper front teeth overlap your lower front teeth when your jaw is closed. A small degree of overlap is completely normal and is actually part of a healthy bite, since it helps protect your teeth and allows your jaw to function properly when you chew and speak. A problem overbite is one where that overlap goes beyond what is considered typical, to the point where it starts to affect comfort, appearance, or the long term health of your teeth and gums.
There are a few common reasons an overbite develops. Genetics are the biggest factor, since the size and shape of your jaw, along with the position your teeth naturally grow into, are largely inherited from your parents. Childhood habits play a role too. Prolonged thumb sucking, extended use of a dummy past the age most children stop, or long term bottle feeding can all gradually push the upper front teeth forward over time, and the effect tends to be more pronounced the longer the habit continues.
Missing teeth, teeth lost early without replacement, and general tooth drift as you age can also contribute to an overbite developing or getting worse later in life, even in adults who had a normal bite as children.
How to tell if you have an overbite worth treating
Most people can spot an overbite simply by looking at how their teeth sit when they bite down naturally in front of a mirror. If your upper front teeth cover a large portion of your lower front teeth, or your lower teeth are barely visible at all when your jaw is relaxed, that overlap is usually more than the typical healthy amount.
There are a few other signs worth paying attention to as well. Jaw discomfort or a feeling of tightness, clicking or popping in the jaw joint when you open and close your mouth, uneven or excessive wear on certain teeth, and difficulty biting into firmer foods comfortably can all point toward an overbite that is affecting function rather than just appearance.
None of these signs confirm an overbite on their own, and some can have other causes entirely. Together with the visual overlap though, they are a good reason to book an assessment with a dentist rather than try to self diagnose from a mirror or a search engine.
Mild, moderate and severe overbite explained
Dentists tend to group overbites into three broad categories based on how pronounced the overlap is and what is driving it. A mild overbite involves a small amount of extra overlap beyond what is typical, and it often causes no real functional problems beyond a cosmetic concern about how the smile looks.
A moderate overbite is more noticeable and can start to cause genuine issues, including uneven wear on the front teeth, mild jaw discomfort, or a bite that feels slightly off when chewing. A severe overbite, which dentists sometimes refer to as a deep bite, involves significant overlap and can be severe enough that the lower teeth barely make contact with the upper teeth at all during normal biting.
The important distinction within a severe overbite is whether it comes from the position of the teeth or from the underlying shape of the jawbone itself. A severe dental overbite, where the teeth are simply positioned badly but the jaw structure is fine, can often still respond well to clear aligner treatment. A skeletal overbite, where the jawbone itself has grown in a way that creates the overlap, usually needs a different approach entirely.
How clear aligners treat an overbite
Clear aligner treatment for an overbite uses a series of custom made plastic trays, with each one in the sequence slightly different from the last. As you progress through the series, typically wearing each tray for one to two weeks before switching to the next, the trays gradually pull the upper front teeth back and push the lower front teeth forward, closing the gap between them step by step.
For overbite cases in particular, dentists will often add small tooth coloured attachments to specific teeth before treatment begins. These attachments act as grip points for the aligner tray, giving it something to push and pull against with more precision than plain aligner plastic can achieve alone. Without attachments, certain tooth movements involved in overbite correction, particularly ones that involve tipping or rotating a tooth rather than just sliding it, are much harder to control accurately.
Your dentist maps the entire sequence out in advance using a digital scan of your teeth, which means the full treatment plan, from your starting bite through to the corrected position, is planned before you receive your first tray. You can read more about how clear aligners work as a treatment more generally if you want the fuller picture beyond overbite cases specifically.
Clear aligners vs Invisalign for overbite treatment
Invisalign is a specific, well known brand of clear aligner, and it does treat overbites using broadly the same approach described above, including the use of attachments for bite correction cases. The underlying mechanics are shared across most reputable clear aligner systems, since they are all built on the same core principle of staged, gradual tooth movement guided by a digital treatment plan.
Where providers genuinely differ is price and how the service is delivered, rather than the fundamental science behind the treatment. A dentist supervised alternative can offer the same quality of care and the same attachment based approach to overbite correction, without the brand premium that comes attached to a well known name. Our full comparison of clear aligners versus Invisalign breaks this down in more detail if you want to weigh the two options directly.
Clear aligners vs traditional braces for overbite treatment
Traditional braces remain a solid option for overbite cases, and for more complex situations involving several teeth that all need significant movement at once, some dentists still prefer them. Braces apply continuous, constant pressure through brackets and wires rather than the incremental, tray by tray pressure that aligners use, which some practitioners find gives them slightly more control in harder cases.
For mild to moderate overbites though, clear aligners generally achieve a comparable result to braces, with the added benefits of being removable for eating and cleaning, and considerably less visible day to day. Many adults in particular choose aligners specifically to avoid the appearance of metal brackets during a visible, multi month treatment period. You can compare the two approaches more fully on our clear braces page if a traditional option is something you are weighing up alongside aligners.
When clear aligners are not enough for an overbite
Clear aligners are not a universal fix for every overbite, and an honest provider should tell you this upfront rather than promising results that are not realistic for your specific case. If your overbite is classed as severe, or if it is driven primarily by the structure of your jawbone rather than the position of individual teeth, aligners alone are unlikely to fully resolve it.
In these situations, a dentist may recommend traditional braces instead, a combination of orthodontic approaches used together, or in less common cases a referral for a broader assessment that looks specifically at jaw structure and growth rather than tooth position alone. Being told that aligners are not the right fit for your particular overbite is not a failure of the treatment itself. It simply means your case needs a different tool to get the right result, and a dentist who tells you this honestly during your assessment is doing their job properly.
How long overbite treatment with clear aligners takes
Treatment length depends heavily on how severe your overbite is to begin with. Mild cases, where the overlap is relatively small and mainly cosmetic, can sometimes be resolved in around six months of consistent wear. Moderate cases typically take somewhere between nine and eighteen months, with the exact figure depending on how many teeth need to move, how far they need to travel, and how consistently the aligners are worn for the recommended hours each day.
A dentist can give you a realistic estimate specific to your case once they have reviewed a scan or impression of your teeth, which will always be more accurate than a general range that is meant to apply to everyone. Wearing your aligners for less than the recommended time each day is one of the most common reasons treatment ends up taking longer than originally planned, so consistency matters as much as the treatment plan itself.
The Lucent treatment process step by step
Treatment begins with either a digital scan at a partner dental practice or an at home impression kit, depending on which option suits you best. A dentist then reviews your case properly, confirming whether your overbite is a good candidate for clear aligner treatment and giving you a realistic idea of how many aligners your specific plan is likely to involve.
Once your treatment plan is confirmed and approved, your aligners are manufactured in stages and sent to you as you progress through the sequence rather than all delivered at once. You wear each tray for the recommended period, usually one to two weeks, before moving on to the next one in order. Check ins are built into the process at key points along the way, giving a dentist the chance to confirm your bite is tracking the way the original plan predicted and to make adjustments if anything needs correcting.
Cost of overbite treatment with clear aligners in the UK
Clear aligner treatment for an overbite in the UK typically costs less than branded Invisalign treatment for a comparable case, and the gap often comes down to brand premium rather than any real difference in the complexity of treating your specific overbite.
Pricing generally depends on how many aligners your plan requires and whether attachments are needed, both of which scale with how pronounced your overbite is at the start of treatment. A mild case needing fewer trays and no attachments will sit at the lower end of the pricing range, while a moderate case needing a longer sequence and attachment support will cost more. For a full breakdown of pricing tiers across different providers, our guide to Invisalign cost in the UK and our dedicated clear aligners cost UK page both go into this in more detail.
Finance and monthly payment options
Because overbite correction can take longer than a straightforward cosmetic straightening case, spreading the cost over several months often makes the treatment considerably more manageable. Lucent offers flexible monthly payment plans, including zero percent finance options, so you are not required to cover the full cost of treatment upfront before you begin.
You can see how the finance structure works in practice in our full guide to clear aligner finance in the UK, or check current plans and monthly figures directly on the finance page.
Why patients choose Lucent for overbite treatment
Patients choosing Lucent for overbite correction tend to point to the same few reasons when asked. Every treatment plan is reviewed by a dentist before anything begins, which means you get a proper clinical assessment rather than a generic result from an online quiz or a quick photo upload. Pricing sits below what most premium branded aligners charge, while still including the same level of dentist oversight throughout treatment that a branded option would offer.
The finance options also make a real difference for overbite cases specifically, since treatment often runs longer than a simple straightening case and the monthly plans make that extended timeline easier to manage financially. If you are still deciding whether clear aligners are the right fit for your particular overbite, our guide to which clear aligner is right for you is a useful next step, or you can read more about why patients choose Lucent directly.
Booking a consultation
The only reliable way to find out whether clear aligners can correct your specific overbite is to get a proper assessment from a dentist, rather than trying to judge severity from a mirror or general information online. You can book a consultation through our appointment page, where a dentist will review your case, confirm whether aligners are suitable, and talk you through what a realistic plan would look like before anything is finalised.
Frequently asked questions
Can clear aligners fully correct a severe overbite?
Usually not on their own, particularly if the overbite comes from the shape of the jawbone rather than tooth position. Severe or skeletal overbites often need traditional braces or a combination of orthodontic approaches instead.
How exactly do clear aligners fix an overbite?
A series of custom made trays gradually move the upper front teeth back and the lower front teeth forward, often supported by small attachments on specific teeth that help the tray apply pressure more precisely.
Is it normal to have some degree of overbite?
Yes, a small amount of overlap between the upper and lower front teeth is a normal, healthy part of most people’s bite. Treatment is usually only needed when the overlap goes beyond that typical range and starts affecting comfort, wear, or appearance.
How can I tell if my overbite is mild or severe without seeing a dentist?
You can get a rough idea by checking how much your upper teeth cover your lower teeth when you bite down naturally, but a dentist is the only reliable way to confirm severity, since jaw structure is not something you can assess accurately from a mirror.
Are clear aligners more expensive than braces for treating an overbite?
Not necessarily. For mild to moderate cases, clear aligner treatment is often comparable in price to traditional braces, and dentist supervised options like Lucent typically cost noticeably less than premium branded aligners for a similar case.
Does overbite treatment with clear aligners hurt?
Most patients feel mild pressure for the first day or two after starting a new aligner in the sequence, since that is the tray actively doing its job. This usually settles quickly and is generally described as discomfort rather than genuine pain.
