How do Crest Whitestrips work?

Crest Whitestrips are thin, flexible strips that are coated with a tooth whitening gel containing peroxide and are designed to conform to the shape of your teeth. They work by keeping the whitening gel on your teeth long enough to get at stain build-up below tooth enamel to visibly whiten your teeth. Crest makes 30-minute twice a day strips as well as 5-minute once a day strips for more convenient whitening.


How do I use Whitestrips? 

It is best if you do not brush your teeth immediately before applying strips. Open the pouch and remove the strip. Peel the strips from the backing liner and align with gum line. Press gently for good contact. Fold the rest of strip behind teeth to keep in place. Wear strips for required amount of time, then remove and discard.

Step 1 - Peel 
For best results, do not brush teeth immediately before applying strips. Open foil pouch and remove slip. Peel the strip back from its backing.

Step 2 - Apply
Apply gel side of strip to teeth and align strips with gum line, pressing gently for good contact. Fold the rest of strip behind teeth to keep in place.

Step 3 - Reveal
Wear the strips for the recommended time, remove and discard. If you notice gel on your teeth, brush, rinse, or wipe it away.



How long do the results last for?

The results will last for as long as 18 months to 2 years but this is influenced by the eating and drinking behaviors of the patient as well as other factors such as taking certain medications and smoking. 



Is it okay to use Whitestrips back to back?

Yes. With all the Whitestrips products except Supreme you can use one strip right after the other (back-to-back). Wear strips for the time instructed, then remove; rinse or wipe if needed, then apply a second strip. Remember if you do get any tooth sensitivity cease use and consult your dentist. Once you have used your initial Crest 3D Whitestrips it is recommended that you use Crest 3D Stain Shield the ongoing 5 minute a day treatment.  



What are the side effects of tooth whitening?

All bleaching gel causes some degree of tooth sensitivity. This is sensitivity to cold/hot fluids and even air can cause discomfort. This is normal and an expected side effect. Some of the brands of bleaching gel contain desensitizing agents which claim to alleviate post bleaching sensitivity. If you have very sensitive teeth or gums, use Crest Gentle Routine White strips.


What do I do if the strips keep coming off?


Try using a mirror to properly apply the strips, making sure the strip is in good contact with the teeth. If the strips begin to slip, close your mouth and create suction to tighten the strips up again. Don't touch the strips excessively with your tongue. You can try gently tucking the strip in the spaces between your teeth with your fingernail, then folding it behind your teeth. You can also try new Crest Advanced Seal- specially designed to strongly adhere to your teeth better with a new revolutionary formula.



What happens if I skip an application?

You can skip or miss a couple of applications without affecting your whitening benefit.



Will Whitestrips remove smoking stains?

Yes, however, smoking stains can be difficult to remove and may take a little longer. If you continue to smoke, your teeth may discolor faster.



Can I brush my teeth immediately after using Whitestrips?

Yes, after using Whitestrips, you can brush gently.




Can Whitestrips be used by children?

No Crest Whitestrips product is not intended for use in children under the age of 18.



Can I wear Whitestrips overnight while I sleep?

 No, do not wear Whitestrips overnight or while sleeping.



Can I eat while wearing Whitestrips?

Eating while wearing a strip is not recommended. Doing so will affect whitening results.



Are Whitestrips harmful to teeth or can they damage the enamel?
