Apply a thin and even layer of the whitening gel into your Aligners – from molar to molar. Then insert the Aligners as usual.
If gel leaks out of an Aligner, remove it with a clean cotton swab.
How long does it take for the whitening gel to work?
For best results, leave the whitening gel on for several hours. We recommend leaving it on overnight:
- Opalescence PF 10%: 8–10 hours
- Opalescence PF 16%: 4–6 hours
You may also apply the whitening gel spread out throughout the day. This won’t affect your whitening. The important thing is that you leave the gel on for a total of approx. 8–10 hours (Opalescence PF 10%) or 4–6 hours (Opalescence PF 16%).
The whitening gel provided is sufficient for 2–3 applications per syringe.
How do I use the whitening gel?
If you don't require attachments, you can whiten your teeth at any time during your Aligner treatment. If you have attachments, you should whiten your teeth at the end of your treatment in order to obtain an even result. Results with whitening gel vary from person to person.
