Can Clear Aligners Correct a Deep Bite? Yes—With the Right Treatment Plan
A deep bite—also known as a deep overbite—occurs when the upper front teeth excessively overlap the lower front teeth when the mouth is closed. This condition is not only a cosmetic concern but can also cause wear on the teeth, jaw discomfort, and bite problems over time. Yes, clear aligners like Invisalign can be effective in correcting a deep bite, especially when the issue is caused by dental misalignment rather than skeletal structure. As with any orthodontic condition, success depends on the severity of the case and consistent aligner use.
What Is a Deep Bite?
A deep bite is a type of malocclusion where the top front teeth cover a significant portion of the lower front teeth—sometimes even touching the gums behind the lower teeth. This overlap can lead to:
Premature tooth wear
Gum irritation
Difficulty chewing or speaking
Temporomandibular joint (TMJ) issues
A collapsed smile or sunken facial appearance
Addressing a deep bite is important not only for aesthetics but also for long-term dental health and bite function.
How Aligners Work to Fix a Deep Bite
Clear aligners are designed to apply controlled, gentle pressure to gradually reposition teeth. In deep bite cases, aligners help:
Move upper front teeth upward (intrusion)
Move lower front teeth downward (extrusion)
Adjust the angulation of the teeth
Improve the vertical relationship between upper and lower arches
This process is planned digitally, allowing for a precise step-by-step correction tailored to your anatomy.
Are Attachments or Additional Tools Required?
In most deep bite treatments, attachments—small, tooth-colored bumps bonded to the teeth—are used to improve grip and control. They help aligners move teeth vertically, which is especially important in bite correction. Your dentist may also incorporate:
Bite ramps to temporarily adjust the bite during treatment
Elastics for more complex cases
Refinements (additional sets of aligners) to fine-tune the result
These tools support tooth intrusion and extrusion—two movements critical to deep bite correction.
How Long Does It Take to Fix a Deep Bite?
Treatment time depends on the depth of the bite, the condition of your teeth, and your consistency in wearing the aligners.
Mild deep bite: 6 to 9 months
Moderate deep bite: 9 to 15 months
Severe deep bite: 15+ months (may require multiple phases)
Aligners must be worn 20 to 22 hours per day for predictable and lasting results.
Why It’s Important to Treat a Deep Bite
Ignoring a deep bite can lead to:
Fractured or worn front teeth
Jaw fatigue and headaches
Aesthetic concerns (shorter-looking lower face)
Worsening of bite misalignment over time
Correcting a deep bite improves your function, comfort, and confidence.
