Invisalign is comfortable for most people. You may feel mild pressure for a day or two when moving to a new set of aligners — a sign they're working.
Dr Ali El-Kabengi, the principal dentist, plans and delivers your Invisalign personally from first scan to final retainer — you're never passed between clinicians.
Invisalign is removable and nearly invisible — you can eat, drink and clean normally. For most cosmetic and mild-to-moderate cases it's an excellent discreet option. A complimentary scan is the best way to confirm suitability.
A member of our team will be in touch — usually within a few hours — to answer questions and book your complimentary consultation and iTero scan. From there we build your personalised plan.
