What This Guide Covers
This guide explains how Invisalign treats a deep bite and helps you decide if clear aligners are a good fit for your situation. A deep bite is one of the most common bite problems orthodontists see. [1] It happens when the upper front teeth overlap the lower front teeth by more than about one-third of their height.
You may hear the terms "deep bite" and "deep overbite" used interchangeably. Both describe the same condition. Some degree of overbite is normal. The issue arises when the overlap becomes excessive and starts causing wear on the teeth, gum damage, or jaw discomfort.
This guide is for adults and teens who have been told they have a deep bite, or who notice their lower front teeth are mostly hidden behind their upper front teeth. It covers how Invisalign works for this problem, what treatment involves, typical costs, and the situations where braces might be the better path.
How Invisalign Corrects a Deep Bite
Invisalign corrects a deep bite by gradually intruding (pushing up) the front teeth and, in some cases, extruding (pulling down) the back teeth. These movements reduce how much the upper teeth overlap the lower teeth. The process relies on a series of custom-made clear plastic trays that apply controlled, light forces to shift the teeth into better alignment.
What Is a Deep Bite?
A deep bite is a type of malocclusion (misalignment of the teeth) where the upper front teeth cover too much of the lower front teeth vertically. In a healthy bite, the upper teeth typically overlap the lower teeth by about 1 to 2 millimeters. When the overlap exceeds roughly 4 millimeters, or more than one-third of the lower tooth height, orthodontists classify it as a deep bite. [1]
Deep bites can be dental or skeletal in origin. A dental deep bite means the teeth themselves have erupted too far or are tilted in a way that creates excessive overlap. A skeletal deep bite means the upper jaw, the lower jaw, or both grew in a way that causes the overlap. This distinction matters because it affects which treatments will work.
Common symptoms include the lower front teeth biting into the gum tissue behind the upper front teeth, excessive wear on the front teeth, and sometimes jaw pain or clicking. Some people have no symptoms at all and only learn about their deep bite during a dental exam.
How the Aligners Move Teeth for Deep Bite Correction
Invisalign uses a technology called SmartTrack material, which is a flexible thermoplastic. Each set of aligner trays is designed to move teeth by about 0.25 to 0.3 millimeters before the patient switches to the next set. For deep bite correction, two main types of tooth movement are programmed into the treatment plan.
The first is anterior intrusion. This means the aligners push the upper front teeth (and sometimes the lower front teeth) slightly upward into the jawbone. This reduces the vertical overlap. The second movement involves the back teeth. In some cases, the plan calls for slight extrusion, or downward movement, of the premolars and molars to build up the bite height in the back of the mouth.
Invisalign also uses precision bite ramps. These are small raised areas built into the plastic on the tongue side of the upper aligners, usually behind the front teeth. When you bite down, your lower front teeth press against these ramps. This creates a controlled force that helps intrude the front teeth and open the bite. Bite ramps are one of the features that make Invisalign particularly useful for deep bite cases.
Attachments, Elastics, and Other Tools
Many deep bite cases require small tooth-colored composite bumps called attachments. Your orthodontist bonds these to specific teeth. The attachments give the aligners something to grip, making it possible to achieve movements that a smooth aligner alone cannot produce. For deep bite correction, attachments are often placed on the premolars or canines to help with intrusion or rotation.
Some patients also need elastics (small rubber bands). These hook from the upper aligners to the lower aligners and apply additional force to help correct the bite relationship between the jaws. Elastics are especially common when the deep bite involves both vertical overlap and a horizontal discrepancy, such as the lower jaw sitting too far back.
Mild, Moderate, and Severe Deep Bites
Invisalign works well for mild deep bites, where the overlap is moderate and the cause is dental rather than skeletal. These cases typically respond predictably to aligner therapy. Moderate deep bites can also be treated successfully, but they often require attachments, bite ramps, elastics, and careful treatment planning by an experienced orthodontist.
Severe deep bites present more of a challenge. When the deep bite is skeletal in origin, meaning the jaw bones themselves are positioned in a way that creates the overlap, clear aligners alone may not produce enough force or the right type of force to correct the problem fully. In these cases, traditional braces, sometimes combined with temporary anchorage devices (small screws placed in the jaw to assist tooth movement), may be necessary. Some patients benefit from a combination approach: starting with braces to achieve the most difficult movements, then finishing with Invisalign for fine-tuning. [1]
What to Know Before Starting Treatment
Understanding your specific type of deep bite and your own habits will help you set realistic expectations before treatment begins.
Who Is a Good Candidate?
Good candidates for Invisalign deep bite treatment are typically teens and adults with mild to moderate overbites caused primarily by tooth position rather than jaw structure. You also need to be willing and able to wear the aligners 20 to 22 hours per day. The only times you should remove them are when eating, drinking anything other than water, and brushing your teeth. [2]
Teens can be good candidates, but compliance is a real consideration. Invisalign Teen aligners include small blue dots (compliance indicators) that fade with wear, giving both the patient and the orthodontist a visual check. An orthodontist can assess whether a teenager's maturity level and daily routine support aligner therapy.
Why Compliance Is Critical
Clear aligners only work when they are in your mouth. Each set of trays is designed to be worn for one to two weeks before you switch to the next set. If you consistently wear the aligners less than 20 hours a day, the teeth do not move as planned. This can lead to a poor fit with later trays, treatment delays, and potentially the need for additional trays or a complete re-scan.
Poor compliance is the single most common reason Invisalign treatments take longer than expected. If you know that remembering to put the aligners back in after meals will be a challenge, discuss this honestly with your orthodontist. They may recommend braces instead, since braces are fixed to the teeth and do not depend on patient compliance for daily wear.
Age Considerations and Timing
Invisalign is typically used for deep bite correction in patients whose jaws have finished growing, or who are close to finishing growth. For most girls, jaw growth is largely complete by age 16 to 17. For most boys, it continues until about 18 to 20. [1] Treating a deep bite before jaw growth is complete can be effective in some cases, but the orthodontist needs to account for remaining growth in the treatment plan.
Adults of any age can have deep bite treatment with Invisalign, assuming the teeth and gums are healthy. If you have gum disease (periodontitis) or significant bone loss, those conditions need to be treated and stabilized first. Moving teeth through weakened bone can cause further damage.
What to Expect During Treatment
Treatment follows a predictable series of steps, from initial consultation through retention after the aligners are done.
Initial Consultation and Treatment Planning
Your first visit will include a clinical exam, digital X-rays, photographs, and usually a 3D scan of your teeth. The orthodontist uses this information to diagnose the type and severity of your deep bite. They will measure the overbite in millimeters and assess whether the cause is dental, skeletal, or a combination of both. [1]
If Invisalign is appropriate, the orthodontist submits the scan data to Align Technology (the company that makes Invisalign). A digital treatment plan, called a ClinCheck, is created. This is a 3D simulation that shows how your teeth will move from start to finish. Your orthodontist reviews and adjusts this plan before your custom aligners are manufactured.
Active Treatment Phase
Once your aligners arrive, you will have an appointment to receive your first set and have any necessary attachments bonded to your teeth. The orthodontist will check the fit and teach you how to insert and remove the trays. Most patients switch to a new set of aligners every one to two weeks.
You will visit the orthodontist roughly every six to eight weeks for progress checks. During these visits, the orthodontist confirms that the teeth are tracking correctly with the aligners. If a tooth is not moving as planned, they may add or reposition attachments, prescribe elastics, or order refinement trays.
Typical treatment time for a deep bite with Invisalign ranges from 12 to 24 months. Mild cases may finish closer to the 12-month mark. Moderate cases with additional crowding or spacing often take 18 to 24 months. Some patients need one or more rounds of refinement trays after the initial set. Refinement trays address small remaining discrepancies and are a normal part of treatment.
Retention After Treatment
When active treatment ends, you will need to wear a retainer. Without retention, teeth tend to shift back toward their original positions. This is called relapse, and it is particularly common with deep bite corrections. The front teeth have a natural tendency to re-intrude if they are not held in place.
Your orthodontist will typically prescribe a removable retainer (often a clear tray similar to an Invisalign aligner) or a fixed retainer (a thin wire bonded behind the front teeth). Many orthodontists recommend wearing a removable retainer full-time for the first several months, then transitioning to nighttime wear only. Following retainer instructions is just as important as wearing your aligners was during treatment. [1]
Cost of Invisalign for Deep Bite
Invisalign for deep bite correction typically costs between $3,000 and $7,000, though costs vary by location, provider, and case complexity. Several factors influence the final price.
The severity of the deep bite plays a significant role. A mild case that requires fewer trays and fewer office visits will generally cost less than a moderate or complex case that needs attachments, elastics, and refinement rounds. Geographic location also matters. Orthodontic fees tend to be higher in major metropolitan areas compared to smaller cities and rural regions.
Many dental insurance plans that include orthodontic benefits will cover a portion of Invisalign treatment, often between $1,000 and $2,000, depending on the plan. Coverage terms vary widely. Some plans cover Invisalign at the same rate as braces. Others may cover a smaller percentage or exclude clear aligners altogether. Contact your insurance provider before starting treatment to understand your specific benefit. [2]
Most orthodontic offices offer payment plans that spread the cost over the length of treatment. Some practices also accept health savings accounts (HSAs) or flexible spending accounts (FSAs), which allow you to pay with pre-tax dollars. Ask about all available payment options during your consultation.
When to See an Orthodontist
An orthodontist should evaluate any deep bite that causes symptoms or concerns about tooth wear, gum damage, or jaw discomfort.
General dentists can identify a deep bite and may even offer aligner treatment for mild cases. However, an orthodontist has two to three years of additional training beyond dental school focused specifically on diagnosing and treating bite problems. [1] For a deep bite, this specialized training matters. An orthodontist can distinguish between dental and skeletal causes, plan intrusion movements precisely, and recognize when aligners alone will not be enough.
You should see an orthodontist if your lower front teeth bite into the roof of your mouth or into the gum tissue behind your upper teeth. You should also seek evaluation if you notice excessive wear on your front teeth, if you experience jaw pain or clicking, or if a general dentist has mentioned a deep bite during a routine exam. Early evaluation does not commit you to treatment. It gives you the information to make a good decision.
If your child has a deep bite, the American Association of Orthodontists recommends an initial orthodontic evaluation by age 7. [1] This does not mean treatment starts at that age. It allows the orthodontist to monitor growth and intervene at the right time if needed.
