How Clear Aligners Work
Treatment begins with a clinical assessment and usually a digital scan. Planning software maps each stage of tooth movement, and a full series of custom trays is manufactured before treatment starts.
Aligners are worn 20–22 hours a day, out only for eating, drinking anything but water, and brushing. Compliance is everything — falling short slows treatment and can stop the trays fitting.
Review appointments in Thornhill are typically every 8–10 weeks. Visits are less frequent than with fixed braces — the clinician confirms progress, issues trays, and adjusts the plan if the teeth aren't tracking as designed.
Aligners vs Fixed Braces in Thornhill
The headline advantage over fixed braces is discretion — trays are nearly invisible. Being removable means no dietary restrictions and easier cleaning, but that same removability is the risk: it only works if you wear them.
For complex movements — large rotations, significant overbite correction, extraction cases — fixed braces tend to be more predictable. For mild-to-moderate cases, well-fitted aligners deliver comparable results with more comfort.

Stage 1 — Initial Assessment
The journey in Thornhill 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.

Cases Where Aligners Shine
