An open bite occurs when the upper and lower teeth do not touch when the mouth is closed. This bite issue may affect the front teeth (anterior open bite) or the back teeth (posterior open bite), and it can interfere with chewing, speech, and smile aesthetics. One of the most asked questions in orthodontics today is whether clear aligners like Invisalign can fix an open bite. The answer depends on the cause, severity, and treatment goals.
This article walks you through how open bites develop, when aligners work best, and what you can expect from aligner treatment.
What Is an Open Bite?
Open bite refers to a lack of contact between opposing teeth. This gap is visible even when the jaw is closed. Common types include:
- Anterior open bite: the front teeth don’t meet
- Posterior open bite: the back teeth don’t make contact
The condition may be due to dental habits or skeletal factors. Habits like tongue thrusting, thumb sucking, or prolonged use of pacifiers during childhood can push the front teeth out of alignment. Skeletal open bites involve jaw development problems and may require more advanced orthodontic or surgical treatment.
Why Correcting an Open Bite Is Important
An untreated open bite isn’t just a cosmetic concern. It can create real health problems such as:
- Trouble biting or chewing food properly
- Difficulty with speech, including lisps
- Jaw discomfort or overuse of other muscles
- Premature tooth wear
- Increased risk of temporomandibular joint (TMJ) issues
Fixing an open bite helps improve oral function and long-term dental health. It also contributes to a more balanced and confident smile.
Can Clear Aligners Fix It?
Clear aligners can absolutely correct many types of open bites. These custom trays are made to fit snugly over the teeth, applying precise pressure to shift them over time. Aligners are particularly effective for dental open bites caused by habits or misaligned tooth positions.
What makes them work:
- Extrusion of front teeth: Aligners can gently move upper and lower front teeth downward until they touch.
- Intrusion of molars: Aligners may also help push back teeth slightly upward, closing the gap in front.
- Jaw rotation: This combination can rotate the lower jaw upward, closing the bite.
- Habit correction: Many aligner cases include plans to address the root causes, such as tongue posture or swallowing habits.
This type of treatment is often combined with the use of attachments or elastic bands that enhance pressure and guidance.
Who Is a Good Candidate?
Not all open bites are alike, and not everyone is suited to clear aligners. Ideal candidates include:
- Individuals with dental open bites, not skeletal ones
- Patients who are consistent and committed to wearing aligners 20–22 hours daily
- Adults and teens without complex jaw discrepancies
- Those willing to follow up regularly and address oral habits if needed
Patients with skeletal open bites—where the jaw bones themselves are misaligned—may require a combination of aligners and surgical or orthodontic treatments for a full correction.
How Long Does Treatment Take?
The average treatment time for correcting an open bite with aligners ranges from 12 to 24 months. The exact duration depends on:
- The size of the open bite
- Whether both the front and back teeth are involved
- The patient’s commitment to wearing aligners as prescribed
- The presence of any oral habits that may interfere with progress
During treatment, patients switch out their aligner trays every 1 to 2 weeks. In more complex cases, refinements or additional aligners may be needed to complete the correction.
What to Expect During the Process
Clear aligner treatment starts with a 3D scan or digital impression of your teeth. Your orthodontist will plan out the movements required to close your bite. Each new aligner shifts your teeth slightly closer to the desired position.
Your provider might also:
- Attach small tooth-colored buttons to your teeth for better grip
- Recommend elastic bands to move the jaws into alignment
- Monitor progress at follow-up visits every 6–8 weeks
Once treatment is complete, retainers are essential to prevent relapse. Patients should wear retainers consistently, especially in the first year, to maintain results.
Advantages of Using Clear Aligners for Open Bite
Clear aligners offer many benefits when treating mild to moderate open bites:
- Discreet appearance: Clear aligners are barely noticeable when worn
- Removable: You can eat, brush, and floss without the restrictions of braces
- Comfortable: No brackets or wires mean less mouth irritation
- Custom plans: Aligners are tailored to your specific bite and needs
In many cases, especially where the bite issue is dental rather than skeletal, aligners provide a predictable and non-invasive solution.
Limitations of Aligner Treatment
While aligners are a great option for many, they are not ideal in all situations. Limitations include:
- Compliance required: Not wearing the trays consistently reduces effectiveness
- Not for severe skeletal issues: Jaw surgery may still be necessary in complex cases
- Slow for complex movement: In certain scenarios, traditional braces may be faster
A thorough consultation with an orthodontist is essential to determine if aligners are appropriate for your case.
One Proven Resource
According to Invisalign, one of the most widely used clear aligner brands, their system is capable of addressing open bites with a high rate of success, especially when caused by dental alignment and not jawbone positioning.
