Aligner Treatment Timeline in Northwick Park

Mild-to-moderate crowding or spacing is often suitable for clear aligners, while more complex cases are more commonly recommended fixed braces. Treatment duration for suitable cases ranges from 3 months for mild presentations to 18+ months for comprehensive full-arch treatment. A photo assessment is a practical first step to get an early indication of suitability, likely treatment duration, and case complexity before attending any in-person consultation.

Stage 1 — Initial Assessment

The journey in Northwick Park usually opens with an assessment — a photo-based remote review or an in-person exam. Remotely, you get an early read on suitability and complexity before paying for anything; in person, the clinician takes X-rays, checks bite, jaw and gums, and scans or photographs your teeth. This stage decides whether aligners are appropriate and how complex the case is.

Stage 2 — Digital Treatment Planning

If aligners are recommended, the clinician builds a digital plan in software like ClinCheck. A scan or impression produces a 3D model, and every stage of movement is mapped across the tray series. You usually see a before-and-after simulation up front — the moment to ask questions and understand exactly what's planned.

Stage 3 — Manufacture and Delivery

Approve the plan and manufacture starts — typically 3-6 weeks. Fitting bonds any attachments the plan needs and gets your first trays in, along with clear guidance on wear hours, when to move to the next tray, and how to keep them clean.

Stage 4 — Active Treatment and Reviews

From here it's tray after tray, each worn for its set period, with reviews in Northwick Park roughly every 6-12 weeks to confirm tracking and catch anything not moving to plan. The whole active phase runs anywhere from 3 months to 18-plus depending on complexity.

Stage 5 — Refinements

Refinements are extra trays made after the first series to finish movements it didn't fully achieve. They're common — expect at least one round. A fresh scan drives a revised plan and a short new tray series. They're included in comprehensive fees, so confirm the refinement policy before you start.

Stage 6 — De-bond and Retainers

At the finish, the attachments come off and retainers are fitted immediately — typically a fixed wire and a night-time clear retainer. From here retention never really ends; consistent wear is what stops the teeth drifting back.
