Can Invisalign fix overbite? What clear aligners can do
Yes, in many cases. Invisalign can improve mild to moderate overbites caused mainly by tooth position. Here’s what it can do, how long treatment may take and what affects the cost.

Understanding your bite
Do I Have an Overbite? What Is It?
An overbite is the vertical overlap between your upper and lower front teeth when your back teeth come together.
A small overlap is normal. An excessive overlap is usually called an increased overbite or deep bite.
What counts as an overbite that needs attention? Your dentist looks at how much of your lower front teeth is covered, whether your teeth touch your gums and how comfortably your bite works. A measurement alone does not decide whether you need treatment.
- Deep bite
- Your upper front teeth overlap your lower teeth too far vertically.
- Overjet
- Your upper front teeth sit too far forwards, sometimes described as “sticking out”.
- Open bite
- Your front teeth leave a gap when your back teeth are together.
You can have an increased overbite and an increased overjet at the same time. An open bite is a different problem, rather than a more severe stage of overbite.2
What can you notice at home? Close your teeth naturally and look in a mirror. Are most of your lower front teeth hidden? Do any teeth press into your gums? Mention these at your consultation. A photograph or mirror check cannot confirm a diagnosis.
What Problems Can an Overbite Cause?
A small, comfortable overbite may need no treatment. A deeper bite can sometimes cause the following problems.2
-
Tooth wearParticularly where the lower teeth repeatedly contact the backs of the upper teeth.
-
Sore or damaged gumsIncluding the roof of the mouth behind the upper front teeth.
-
Difficulty biting comfortablyDepending on how your upper and lower teeth meet.
-
Concerns about your smileEspecially if your lower front teeth appear hidden.
If your teeth repeatedly catch your gums or you notice new wear, arrange a dental assessment.
Jaw pain or clicking should also be assessed separately. Changing your bite cannot be promised to resolve these symptoms.
At Lodge Causeway Dental Centre in Fishponds, we can assess how your teeth meet and discuss your options. If you are considering Invisalign in Bristol, understanding your bite is the first step.
Treatment possibilities
Can Invisalign Fix Overbite? The Key Factors
Invisalign uses a series of clear, removable aligners to move teeth gradually. Deep-bite correction may involve adjusting the height and angle of the front teeth and the way the back teeth meet.
Invisalign may be a suitable option, but the treatment needs careful planning and monitoring.
What does the research say? A 2025 systematic review of 18 studies found that clear aligners can improve mild to moderate deep bites caused mainly by tooth position. However, the evidence was rated low quality, and the correction achieved often fell short of the digital plan.[1]
- The cause of your overbite
Tooth-position problems are different from a significant mismatch between the jaws.
- The movements required
Crowded teeth, gaps, protruding teeth and other bite problems can add to the work involved.
- Your age and remaining growth
Treatment options differ between growing teenagers and adults.
- Your dental health
Tooth decay and gum disease need to be managed before teeth straightening begins.[2]
- Your daily routine
Invisalign recommends wearing aligners for about 22 hours a day. Regularly leaving them out can affect progress.[3]
What might your plan include? Some plans use small tooth-coloured attachments to help the aligners grip. Others use bite ramps, which are small raised areas within the aligners, or elastics, which are small rubber bands helping the upper and lower teeth work together.[4]
You may also need refinements: an additional scan and extra aligners to adjust movements that have not happened as planned. A digital smile preview shows the intended outcome; it is not a guarantee of the final result.[5]
Invisalign for Mild Overbite: Real Results
If the overlap is only slightly greater than ideal and your jaws fit together well, Invisalign may be a suitable way to improve your bite.
Treatment may also straighten mildly crowded or rotated teeth. However, straighter front teeth and a corrected bite are separate goals: your plan should explain both.
The research supports clear aligners for suitable mild dental deep bites, but there is no single result or treatment time that applies to everyone.[1] Ask your dentist:
- How much should my overbite change?
- Will both upper and lower teeth need treatment?
- Does the plan correct my bite as well as the appearance of my teeth?
- Are extra aligners included if they are needed?
A limited correction may take less time than a more involved treatment. However, the studies below do not establish a separate, reliable average for mild overbites.
Moderate Overbite Transformations with Invisalign
A moderate deep bite usually needs more coordinated movement across the upper and lower teeth.
A study published online in 2025, involving 37 adults, reported an average overbite reduction of 4.1 mm, with treatment lasting an average of 21.1 months. All patients used bite ramps, and many also used elastics.[4]
Results vary considerably between studies. In a 2024 study, 15 patients who completed treatment achieved an average reduction of about 1.25 mm over 23 months, despite additional aligners. Their final correction was smaller than originally planned.[5]
These were small studies looking back at completed treatment. They demonstrate what has happened in selected patients, rather than predicting your individual result.
| Patients studied | Reported average time |
|---|---|
| 37 adults with dental deep bites of varying severity[4] | 21.1 monthsIndividual treatments ranged from 7 to 34 months. |
| 15 completed adult deep-bite cases involving additional aligners[5] | About 23 months |
| 36 adults treated with clear aligners for anterior open bite[6] | About 19 months |
These are study averages, rather than standard treatment packages. Your dentist should estimate your timescale after assessing your full bite and update it as treatment progresses.
What about a severe overbite? Invisalign may still be an option in selected cases. However, a very deep bite, gum injury or complex tooth movements may make specialist orthodontic assessment appropriate. Fixed braces or a combination of techniques may offer better control for some patients.[7]
Open Bite Treatment: Can Invisalign Fix It?
Yes, clear aligners can close some open bites. An anterior open bite means the front teeth do not meet when the back teeth are together. It can make biting through foods such as sandwiches difficult.
A systematic review published online in 2024, covering 14 studies, found an average improvement of approximately 2.8 mm with clear aligner treatment in adults. Most included studies had a moderate risk of bias, so their findings need to be interpreted in context.[8]
The roughly 19-month average in the table above comes from one separate study of 36 adult Invisalign patients. It should not be treated as the expected time for every open bite.[6]
Your assessment needs to consider the tooth positions, jaw pattern and any habits or tongue function that may affect the bite. A substantial skeletal open bite may require specialist treatment, sometimes including jaw surgery.[9]
Skeletal Problems: When the Jaws Affect Your Bite
A skeletal bite problem involves the size, position or relationship of the jaws, rather than tooth position alone.
In adults, Invisalign moves teeth within the jaws. It cannot reliably correct a substantial mismatch between the jaw bones.
Some patients can achieve a useful improvement through tooth movement alone. Others need fixed braces, additional orthodontic techniques or a combination of orthodontics and jaw surgery. Growing teenagers may have different options, including appliances designed to make use of remaining growth.[7][9][10]
A pronounced jaw discrepancy does not automatically mean surgery is necessary. It means you need an assessment that explains what each option can realistically achieve.

Invisalign in Bristol · Cost guide
How much does Invisalign cost for overbite?
There is no fixed “overbite price”. Your fee depends on the tooth movements needed, the treatment plan and whether one or both rows of teeth need treatment. At Lodge Causeway Dental Centre, a free consultation is the starting point for discussing your options.
LCDC’s published Invisalign fees
- Upper or lower teeth
- £1,250One row of teeth
- Upper and lower teeth
- £2,500Both rows of teeth
Published fee guide, checked November 2026. Suitability, your final fee and package details are confirmed after assessment. View LCDC’s current fees.
The £1,250 single-row fee should not be assumed to cover overbite correction. Improving how the upper and lower teeth meet may require treatment of both rows. Your dentist will explain what your bite needs.
Does a more complex bite always mean a particular package? No. Express, Lite, Moderate and Comprehensive are Invisalign package names; they do not directly match mild, moderate or severe overbites. An open bite or a problem involving the jaws needs its own assessment. The appropriate plan comes before the price.

Checked November 2026. An “arch” means one row of teeth. Oxford’s Invisalign fee table does not specify the number of arches for these packages. Southsea describes complex treatment fees as a guide, with the final fee confirmed in a treatment plan. Planning, records or retainers may be charged separately.
