Open Bite

Conditions We Assess and Treat with Invisible Aligners

An open bite is a type of malocclusion where the upper and lower teeth do not meet when the mouth is closed. Instead of coming together evenly, a visible gap remains between the biting surfaces—most commonly in the front teeth (anterior open bite), but sometimes affecting the back teeth (posterior open bite). This separation can affect speech, chewing, tooth wear and overall smile aesthetics.

At Pro Aligners, we can treat many mild to moderate open bites using advanced clear aligner therapy. With precise digital planning and expert oversight, clear aligners can gently guide the teeth into proper contact, restoring function and creating a balanced, confident smile.

What Causes an Open Bite?

Open bites can occur throughout childhood or develop gradually in adulthood. The most common causes include:

1. Tongue Thrusting

A habit in which the tongue pushes forward when swallowing or speaking. Over time, the constant pressure may contribute to upper and lower teeth not meeting properly.

2. Thumb or Finger Sucking

Prolonged thumb, finger or dummy/pacifier habits can push upper teeth forward, creating space between the arches.

3. Genetics and Jaw Growth

Skeletal differences in jaw shape or growth patterns can lead to an open bite, particularly if the upper jaw grows away from the lower jaw vertically.

4. Incorrect Eruption of Teeth

If teeth erupt abnormally or are blocked, it may result in bite imbalance and gaps between upper and lower teeth.

5. TMJ Issues

Mouth posture changes due to jaw discomfort can cause long-term bite problems.

6. Prolonged Use of Bottles

Extended use during childhood may encourage forward tongue posture or incorrect swallowing patterns.

7. Natural Ageing

As teeth naturally shift over time, open bite patterns can emerge, especially if retainers weren’t worn after previous orthodontic treatment.

Common Symptoms

Open bites may appear visually obvious, or you may only notice them during certain functions like eating or speaking.

  • A visible gap between upper and lower front teeth when biting
  • Difficulty biting into foods such as apples or sandwiches
  • Speech changes, including lisping or whistling
  • Excessive strain on back teeth
  • Uneven or rapid wear on molars
  • Gum irritation
  • Jaw discomfort or fatigue
  • Aesthetic concerns due to incomplete smile closure

Why Treat an Open Bite?

Addressing an open bite goes beyond cosmetic improvement. It may help support improved oral function, long-term dental health and overall quality of life.

Functional Benefits

  • May improve biting and chewing
  • May support clearer speech
  • May reduce jaw strain and TMJ pressure
  • Can help distribute bite forces more evenly

Aesthetic Benefits

  • A smile that closes properly
  • More balanced facial proportions
  • Improved confidence in speaking and laughing

Addressing an open bite early may support better outcomes.

Can Clear Aligners Treat an Open Bite?

Yes—many dental open bites and mild skeletal open bites can be successfully treated using clear aligners. Modern technology allows aligners to:

  • Intrude or extrude specific teeth
  • Correct forward tongue posture
  • Create a more natural alignment
  • Improve the bite relationship

At Pro Aligners, our experienced team digitally plans every tooth movement with precision, supporting predictable and safe open bite correction.

How Pro Aligners Treat an Open Bite

Our open bite treatment combines advanced digital planning, controlled tooth movement and dentist-led monitoring.

1

Complete Digital Bite Assessment

Your treatment begins with a 3D digital scan that captures your bite from every angle. We analyse the size of the open bite, the cause, and which teeth need repositioning.

2

Tailored Aligner Movements

Aligners apply gentle, consistent pressure to guide teeth into correct contact. This may include extruding the front teeth, intruding back teeth, and correcting the angulation of incisors.

3

Attachments for Precision

Small, discreet tooth-coloured attachments may be used to improve grip and support more complex movements, enabling accurate bite closure.

4

Habit Correction (If Needed)

If your open bite is caused by tongue thrusting, we may advise additional exercises or techniques to retrain swallowing patterns alongside aligner treatment.

5

Unlimited Refinements

As open bites can be intricate, Pro Aligners includes unlimited refinements to help fine-tune tooth positions toward improved bite closure.

6

Retainers to Maintain Your Results

Once treatment is complete, two complimentary retainers are provided to help hold the teeth in position and support long-term stability.

Who Is Suitable for Open Bite Treatment?

You may be eligible for clear aligner treatment if you have:

  • A mild or moderate dental open bite
  • Difficulty biting or chewing
  • Speech changes due to front-tooth separation
  • Back teeth taking too much pressure
  • A previous open bite returning after braces
  • Aesthetic concerns when smiling or closing your mouth

How Long Does Open Bite Treatment Take?

Treatment time varies depending on the severity and complexity, but most open bite cases take:

10 to 18 months

Milder cases may complete faster, especially with strong patient compliance.
