Frequently asked questions
Find all the answers you need before starting your Crest 3D Whitestrips routine.
Which treatment duration should I choose?
We offer several pack sizes so you can choose the duration that best suits your routine.
5 days to try the treatment, 10 days for a treatment of moderate duration, 15 days for a longer treatment and 20 days for a full treatment.
How do I use Crest 3D Whitestrips?
Peel the strips off their backing and place the gel side directly against your teeth.
Gently adjust the strips so they fit closely around the shape of your teeth.
Leave the strips on for 30 minutes before gently removing them.
How long should I leave the strips on?
Leave the strips on for 30 minutes.
Gently remove the strips once the 30 minutes are up.
When can I expect to see a difference?
Results become visible gradually during treatment and may vary from person to person.
Your starting tooth shade, eating habits and how consistently you use the strips can affect the results.
Can my teeth become sensitive?
As with other whitening treatments, your teeth may sometimes become temporarily sensitive.
Use the strips less often, or stop using them if symptoms are severe or persistent, and ask your dentist for advice.
