Q. Is it okay to use Crest Whitestrips on the back of my teeth?

A. No, it is not recommended. The strips provided for your upper and lower teeth are designed to fit the front teeth only. Using the strips on the back teeth may result in the strips coming loose and eventually falling off during the wear period.

Q. What can I do if the whitestrips keep coming off? 

A. Look into 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 Crest 3D White Whitestrips Advanced Vivid or Professional Effects which have Advanced Seal technology—specially designed to strongly adhere to your teeth.
