Invisalign® is the world’s most advanced clear aligner system, a subtle, highly effective way to gradually move your teeth into their ideal position without a single metal bracket in sight. Using a series of custom-made, virtually invisible aligners, Invisalign gently guides your teeth to where they should be, on your terms and at your pace. At Park Street Dental Clinic in Thame, we’re proud to be an official Invisalign® provider. Whether you’re dealing with crowding, spacing, overbites, underbites, or just want a straighter, more confident smile, Invisalign can treat a wide range of cases from simple touch-ups to more complex corrections. Unlike fixed braces, Invisalign aligners are completely removable. Eat what you like, clean your teeth as normal, and take them out for those extra special occasions. Most patients love how little their life has to change to get the smile they’ve always wanted.
Getting started is easier than you might think. Once we confirm that Invisalign is right for you, we use our state-of-the-art iTero intraoral scanner to create a precise 3D digital map of your teeth, no messy impressions required. This technology allows you to see a preview of your results before treatment even begins. From your scan, we generate a personalised ClinCheck®, a short 3D animation showing the exact movements your teeth will make and what your final smile will look like. It’s one of the most reassuring parts of the process, and patients love seeing their transformation before it happens. Once your custom aligners are ready, you’ll swap to a slightly different set every 1–2 weeks, with each set gently nudging your teeth closer to their final position. Regular check-ins with our team ensure everything is progressing perfectly. Most straightforward cases complete in 6–12 months, with more complex cases typically finishing within 12–24 months. Throughout treatment, we’re with you every step of the way, from your first scan to your final retainers.
Invisalign Lite is designed for patients with mild crowding, minor spacing issues, or small alignment corrections. Using up to 14 sets of aligners, it delivers noticeable results in a shorter timeframe, often within 6 months. It’s the ideal entry point for patients who want to improve their smile without a lengthy or complex treatment plan. A great choice if you’ve previously had orthodontic treatment but your teeth have shifted over time.
Invisalign Go focuses on the teeth most visible when you smile, your front six to eight teeth on both arches. It’s a streamlined, affordable option for adults who are happy with their back teeth but want to refine the appearance of their front smile. Quick, targeted, and discreet, Invisalign Go is popular with patients who want a confidence-boosting result with minimal disruption to daily life.

Free from the discomfort of metal braces, Invisalign Teen lets young patients eat normally, play sports, and go about their lives, all while confidently working towards a straighter smile.
