How does invisalign work?

  1. 01

    Orthodontic assessment

    Suitability, complexity and likely duration are discussed openly.

  2. 02

    Digital plan

    A scan is used to plan tooth movement stage by stage.

  3. 03

    Aligner wear

    Aligners are changed on a set schedule with periodic reviews.

  4. 04

    Refinement

    Additional aligners are often used to finish detail movements.

  5. 05

    Retention

    Fixed and/or removable retainers hold the result.

What are the benefits?

  • Removable for eating and cleaning
  • Discreet compared with fixed appliances
  • Corrects position without removing tooth tissue
  • Often reduces how much restorative work is needed afterwards

What are the limitations?

  • Depends heavily on wear compliance
  • Complex skeletal or severe cases may need fixed appliances or specialist referral
  • Does not change tooth colour

What are the risks of invisalign?

  • Relapse without retainer wear
  • Temporary discomfort or speech changes
  • Root resorption and gum recession are recognised orthodontic risks
  • Decalcification if hygiene is poor

What are the alternatives to invisalign?

How long does invisalign last?

Corrected positions are stable for as long as retainers are worn as instructed. Retention is lifelong.

How is invisalign maintained?

  • Retainer wear as prescribed
  • Retainer checks and replacement when worn

Common questions

Invisalign: common questions

All frequently asked questions

Is Invisalign suitable for adults?

Yes. Invisalign is widely used by adults, provided the teeth and gums are healthy and the aligners are worn for the prescribed number of hours each day. Suitability is confirmed at an orthodontic assessment.

Can crooked teeth be treated without veneers?

Often, yes. Correcting tooth position with clear aligners or fixed appliances frequently removes the need for veneers, or reduces the treatment to whitening and small amounts of bonding.

How long does a smile makeover take?

A makeover limited to whitening and bonding can take a few weeks. Where alignment is included first, the overall plan usually runs from several months to around a year, followed by retention and review.
