Overjet
Conditions We Treat with Premium Invisible Aligners
Overjet is a type of bite misalignment where the upper front teeth protrude forward, sitting significantly ahead of the lower front teeth. Unlike an overbite—which refers to vertical overlap—overjet describes the horizontal distance between the upper and lower teeth. When this distance is too large, it creates a forward-projecting appearance of the upper teeth, sometimes referred to as “buck teeth.”
At Pro Aligners, we use advanced clear aligner therapy to treat mild to moderate overjets with precision, comfort and discretion. Our expert-led planning ensures controlled tooth movement that not only improves appearance but also enhances function, bite balance and long-term oral health.
What Causes an Overjet?
Overjet can develop for a variety of genetic, developmental and lifestyle-related reasons.
Genetics
The size and shape of the jaw and teeth are inherited traits. If the upper jaw naturally sits further forward—or the lower jaw sits further back—an overjet is more likely to develop.
Thumb Sucking & Dummy Use
Prolonged thumb sucking, finger sucking or dummy/pacifier use can push the upper teeth forward, increasing the overjet.
Tongue Thrusting
A swallowing pattern where the tongue pushes against the front teeth can gradually move them forward.
Missing or Small Lower Teeth
If lower teeth are missing or undersized, the upper teeth may appear more prominent.
Lower Jaw Underdevelopment
If the lower jaw grows at a slower rate than the upper jaw, this can cause the upper teeth to protrude more significantly.
Natural Ageing & Tooth Movement
Even in adulthood, teeth can shift forward over time, making an existing overjet more pronounced.
Orthodontic Relapse
If retainers are not worn after braces, the teeth may drift forward again, recreating an overjet.
Common Symptoms
An overjet can affect both the appearance of the smile and the function of the bite. Patients often experience:
- Upper front teeth noticeably protruding
- Difficulty biting into foods
- Speech concerns such as slight lisping
- Increased risk of chips or fractures to front teeth
- Lip incompetence (difficulty closing lips fully)
- Shortened chin or recessed lower face appearance
- Gum irritation around front teeth
- Lower teeth biting into the roof of the mouth (severe cases)
- Reduced confidence in smile aesthetics
Even mild overjet can cause future dental problems if not corrected.
Why Treat an Overjet?
Treating an overjet provides significant functional, aesthetic and long-term health benefits.
Functional Benefits
- Improved bite and chewing efficiency
- Reduced risk of trauma to protruding front teeth
- Better alignment of upper and lower arches
- Improved speech clarity
Aesthetic & Health Benefits
- A more balanced facial profile
- Less prominence of the upper teeth
- A more harmonious and symmetrical smile
- Reduced gum strain and enamel wear
- Enhanced long-term bite stability
An untreated overjet can worsen with age, making early intervention particularly valuable.
Can Clear Aligners Fix an Overjet?
Yes. Clear aligners are highly effective for mild to moderate overjets, especially when supervised by aligner-focused orthodontic clinicians. Clear aligners work by moving upper teeth backward, moving lower teeth forward (in certain cases), and correcting the angulation of front teeth.
Severe skeletal overjets may require additional orthodontic or surgical input, and we will guide you accordingly.
How Pro Aligners Treat Overjet
Our approach is precise, predictable and fully digital.
3D Digital Scan & Bite Evaluation
We begin with a high-definition scan to measure the exact horizontal distance between your upper and lower front teeth. This digital model allows us to plan every movement required to reduce the overjet.
Backward Movement of Upper Teeth
Aligners gradually guide the upper front teeth backward into a more natural, functional position.
Forward Movement of Lower Teeth
In some cases, the lower teeth can be gently advanced to meet the upper teeth more evenly.
Attachments for Complex Movements
Tooth-coloured attachments may be used to help control torque, root position and angulation—essential for overjet correction.
Correction of Related Issues
Our treatment addresses all contributing factors such as crowding, spacing, overbite, and rotations for a stable and balanced smile.
Unlimited Refinements
Pro Aligners includes unlimited refinements, ensuring that final tooth position and bite alignment are perfected.
Retainers to Lock In Your New Smile
At the end of treatment, you will receive two free retainers to maintain results and prevent relapse.
Who Is Suitable for Overjet Correction?
Most patients with mild to moderate overjet are excellent candidates for Pro Aligners. You may be suitable if:
- Your upper teeth sit noticeably forward
- Your lower jaw appears recessed
- You have difficulty biting into foods
- You’ve had braces before and the overjet has returned
- You want a discreet alternative to metal braces
- You experience speech changes linked to protruding teeth
How Long Does It Take to Fix an Overjet?
Treatment time depends on the severity of the overjet and any related issues such as crowding. Most cases take:
8 to 18 months
Mild cases may complete sooner.
