How long does Invisalign take?

Quick answer

How long does Invisalign take?

Mild alignment can finish in a few months; more comprehensive Invisalign at York House Dental Practice in West Byfleet often takes around 12 to 18 months.

Your dentist gives a realistic estimate after a 3D scan, not from a generic advert. Wear time of 20–22 hours a day is what actually decides the calendar.

What you need to know

Tray changes are usually weekly or fortnightly. Missed wear adds weeks. Attachments (small tooth-coloured bumps) and refinements (extra trays at the end) are normal, not a sign that treatment has failed. Read why Invisalign attachments and IPR may be used for more detail.

Limited cases start from £2,995. Typical complete treatment is quoted as a package — currently £3,995 at this practice — with more complex cases up to £4,495, and includes the plan, reviews and, where included, retainers. Ask what happens if you need extra trays.

Teenagers and adults are both assessed individually. If fixed braces would be faster or more predictable, we will say so on the braces page. Book a free scan via Invisalign in West Byfleet.
