Invisalign

A brand of clear removable aligners used to gradually straighten teeth through a series of custom-made plastic trays.

What is Invisalign and how does it work?

Invisalign is a system of clear, removable plastic aligners used to straighten teeth. A digital scan of your teeth is taken, from which a series of custom-made trays are manufactured by Align Technology.

You wear each tray for approximately one to two weeks before progressing to the next. Each tray applies gentle, graduated pressure to move teeth incrementally toward the planned position. Treatment typically takes six to twenty-four months depending on case complexity.

The trays are removed for eating, drinking and cleaning, which simplifies oral hygiene during treatment. Periodic check-up appointments allow your dentist to confirm progress and issue the next series of aligners.

Ways to pay for Invisalign

Many UK dental clinics let you spread the cost of treatment through a monthly payment plan arranged with a finance provider. Terms, eligibility and any interest depend on the provider and your circumstances — always read the agreement and ask your clinic for a written, itemised quote before you commit.

What affects the cost of Invisalign?

The main factors are the complexity of tooth movement required (minor corrections vs significant realignment), the Invisalign product tier (Lite for simpler cases, Comprehensive for complex ones), the number of refinement rounds included, and your clinic's location and overheads.
