Before & after · Clear aligners

Worth every tight day: an aligner patient's smile reveal

Key points

  • The video catches a patient's reaction on seeing their finished smile.
  • Each new set of aligners can feel snug for a day or two while the teeth move.
  • That pressure is normal and usually eases quickly.
  • After the reveal, retainers keep the teeth from drifting back.

About this transformation

A feel-good 38-second clip of a patient's reaction at the end of clear aligner treatment with Dr Sarah Sadek.

Results vary, and suitability is checked at a free aligner consultation at Waterloo Dental.

Questions we often hear

How long does each aligner feel tight?

Usually a day or two after you switch to a new set. Changing aligners at night can help, as you sleep through the first few hours.

Can I still go out and socialise with aligners?

Yes. You take them out to eat and drink anything other than water, then clean your teeth before putting them back.

How do I keep my result?

Wear your retainers exactly as advised, especially in the first year after treatment.
