Advantages & Features

  • A whiter smile after just 3 days
  • Professional-level results at a fraction of the cost (vs light & laser systems)
  • Revolutionary Advanced Seal technology for no-slip whitening
  • FlexFit - stretches and moulds to the teeth


Crest 3D Whitestrips LUXE Supreme FlexFit is comprised of thin, flexible strips that are coated with a tooth whitening gel containing peroxide. Designed to conform to the shape of your teeth, they work by keeping the whitening gel on your teeth, with no slipping or gel loss, to provide strong effective teeth whitening.

  • No dental impressions required
  • Strips are ready-made so you can use them right away
  • At home or on the road, strips are portable enough to be used anywhere, at any time during the day


Whitening Strips have the whitening gel already added to them so they deliver a consistent, controlled dose each time. Strips do not have to be loaded before every use, unlike trays, which can cause oral irritation if too much gel is added.

  • Pre-filled strips to control dosage
  • Reduces gel from going over gums


For best results Crest 3D Whitestrips LUXE Supreme FlexFit should be worn for 60 minutes once a day for 7 days.

Step 1: Peel

For best results, do not brush your teeth immediately before applying the strips. Open the foil pouch and remove the slip. Peel the strip from its backing.

Step 2: Apply

Apply the gel side of the strip to your teeth and align the strips with your gum line, pressing gently for good contact. Fold the rest of the strip behind your teeth to keep it in place.

Step 3: Reveal

Wear your whitestrips for the recommended time, then carefully remove them and discard. Rinse your mouth and brush your teeth. Enjoy your new smile.

I usually order the Professional but decided to try these after reading reviews, as they have the flexible fit. They stretch which is the main difference, so cover a few more teeth. They were really easy to use and my teeth are nice and white! I get lots of comments :)
