You’re wondering if clear aligners can fix an overbite and what the journey looks like in the UK—costs, timeframes, and the exact steps (digital scan → 3D plan → treatment → retainers).

What is an overbite?

An overbite happens when your upper front teeth overlap your lower front teeth more than normal. A slight vertical overlap is normal, but a deep overbite (where the overlap is excessive) can lead to gum trauma, enamel wear, jaw strain, and headaches over time.
Common signs: heavy front-tooth wear, lip strain to close, jaw discomfort, or “shortened” lower teeth.

Overbite vs. overjet (quick clarity)

People often mix these up.

• Overbite = vertical overlap (how “deep” the bite is).

• Overjet = horizontal protrusion (top teeth jutting forward).
  Both can be improved with orthodontics; your 3D plan will show which you have.

Types of overbite you’ll hear about

• Mild overbite: noticeable overlap, usually manageable with aligners alone.

• Deep overbite: excessive overlap; may need elastics or staged movements.

• Skeletal deep bite: less common; some cases require combined approaches or referral.
  Your Smileie orthodontist will confirm which applies after your digital scan and exam.

Can clear aligners fix an overbite?

In many adult cases, yes. Clear aligners use programmed, staged tooth movements to:

1. open the bite by carefully intruding/extruding specific teeth,

2. level the arches, and

3. refine your bite with attachments and elastics (when prescribed).
   Treatment length varies, but many cosmetic-focused cases fit into a 4–6-month plan with Smileie—your exact timeline depends on severity and biology.

The Smileie UK pathway (what to expect)

1. Digital scan & bite photos
   Book a digital scan at a Smileie clinic. We’ll capture your teeth and bite, take any necessary radiographs per your clinician’s judgment.

2. Personalised 3D Treatment Plan
   You’ll preview tooth movements and your projected outcome on a 3D treatment plan before you start.

3. Aligners manufactured & delivered
   Once approved, aligners are precision-made and typically delivered in ~2–3 weeks.

4. Smart monitoring + clinic support
   You’ll track progress with online check-ins, and in-clinic visits are available when needed. Your care stays dentist-led throughout.

5. Finish strong: whitening + retainers
   Professional whitening is included, and you’ll receive two sets of retainers to keep your new bite stable.

Benefits of treating an overbite with clear aligners

• Discreet & comfortable: low-profile trays fit daily life.

• Predictable planning: your 3D plan shows the staged path to correction.

• Hygiene friendly: removable for eating and brushing.

• Lifestyle fit: most desk, gym, and social routines continue uninterrupted.

How long will it take?

Many cosmetic adult overbite cases complete in 4–6 months with weekly or bi-weekly changes (your clinician sets the schedule). Complex bites take longer. Your scan + 3D plan provide the realistic estimate.

Costs in the UK

Pricing depends on complexity and length of care. See Pricing for current packages and instalments. Aligners, remote check-ins, whitening and two sets of retainers are included with Smileie packages.

Who’s a good candidate?

• Mild–moderate deep bite or combined overbite/overjet

• Healthy gums and teeth (or ready to address any issues first)

• Able to wear aligners consistently (20–22 hours/day) and follow check-ins

Getting started (next steps)

1. Book a digital scan to confirm suitability.

2. Approve your 3D plan.

3. Start your aligners and follow the monitoring schedule.

4. Lock in the result with retainers and good daily hygiene.

FAQs

Can aligners really fix a deep overbite?
Often, yes—especially when it’s dental (tooth position) rather than skeletal. Your Smileie orthodontist will tell you if elastics or additional steps are needed.

Will I need X-rays?
Your clinician may include them to plan safely. If you choose to skip radiographs, you’ll still receive a thorough in-clinic check-up before treatment proceeds.

How soon will I see changes?
Many people notice visible changes in 6–8 weeks, with full results guided by your approved 3D plan.

Do I get retainers?
Yes—two sets are included to maintain your new bite.
