What Is an Overbite?
An overbite (or excessive overjet) occurs when the upper front teeth excessively overlap the lower front teeth. While a slight overjet is normal, a deep ones—where the upper teeth significantly cover the lower teeth—can lead to a host of dental and medical problems.
There are two main types:
- Skeletal overjet: Caused by bone structure, often requiring more comprehensive treatment.
- Dental overjet: Caused by the positioning of the teeth rather than the jawbone, often treatable with aligners.
Common symptoms include:
- Aesthetic concerns with facial profile
- Difficulty biting or chewing
- Jaw discomfort or clicking
- Worn tooth enamel

How Aligners Work
Clear aligners are custom-made, transparent trays that fit over your teeth. They work by applying gentle pressure over time to shift the teeth into their optimal positions. This includes addressing vertical discrepancies caused by bite issues, such as a prominent overjet.
When designed by orthodontists using advanced 3D scanning and digital modelling, aligners can precisely target problem areas, guiding teeth movement to correct not only alignment but also the overall bite.

Step-by-Step: How to Fix Overjet with Aligners
1. Initial Consultation and Diagnosis
Your journey begins with an evaluation by an orthodontist. They will:
- Examine your bite and jaw alignment
- Take digital scans or X-rays
- Confirm whether the condition is a dental or skeletal overjet
- Assess if aligners are the best solution
Mild to moderate teeth overlap are typically ideal cases for aligner therapy.
2. Customized Treatment Plan
If aligners are suitable, your clinic will create a 3D model of your mouth to simulate each phase of the treatment. You’ll be able to see how your bite will transform over time.
The treatment plan often includes:
- A timeline of aligner changes (usually every 1–2 weeks)
- Projected tooth movements
- Attachments or elastics (if needed for complex bite correction)
3. Wearing the Aligners Consistently
You’ll receive a set of aligners to wear for about 20–22 hours a day. Consistency is key. These trays must be worn almost full-time to ensure proper progression.
You’ll typically change trays every one to two weeks, with each new set bringing your teeth closer to their correct position.
4. Using Attachments or Elastics (Optional)
Some bite problems require additional support:
- Attachments: Small, tooth-colored buttons bonded to your teeth to give aligners better grip.
- Elastics: Rubber bands that help reposition the jaw to fix vertical misalignments, such as a deep bite.

5. Monitoring Progress
Your orthodontist will check your progress every 6–8 weeks. They may:
- Adjust your plan based on how your teeth respond
- Provide refinements or additional trays
- Add or remove attachments
6. Final Adjustments and Retention
Once the bite issue is resolved, your dentist may issue refinement aligners to perfect the results. After the final set, a retainer is used to prevent relapse.
Benefits of Using Aligners
Discreet Appearance
Unlike braces, aligners are nearly invisible. This makes them a favourite for adults and teens who prefer a subtle solution.
Removable Convenience
You can take aligners out for eating, drinking (non-water), brushing, and flossing. This results in better hygiene and fewer dietary restrictions.
Shorter Dental Visits
Aligner treatments require fewer office visits compared to braces, saving time for busy schedules.
Precise and Predictable
Thanks to digital treatment planning, the aligners guide your teeth with high precision, especially effective for dental bite issues.
Comfortable and Smooth
Aligners are custom-designed to fit snugly and are made of soft, medical-grade plastic, minimizing mouth irritation.
