Is it okay to use Crest 3D White Whitestrips on my back teeth?
No, it is not recommended. The strips provided for your upper and lower teeth are designed to fit the front teeth only. Using Crest 3D White Whitestrips on the back teeth may result in the strips coming loose and eventually falling off during the wear period.
Can I switch strips (wear upper strip on bottom teeth and vice versa)?
No, We do not recommend switching strips. Although the strips would still work if switched, each upper strip is designed specifically to cover the area of your upper teeth while each lower strip is designed specifically to cover the area of your lower teeth. These shapes were designed to keep the strips in place while covering those teeth that show when you smile. Wearing a lower strip on your upper teeth will result in you covering less area on your upper smile teeth.
Can I cut the Whitestrips into smaller pieces to fit them into different spots in my mouth?
No. If cut into smaller pieces, the strips could dislodge from the teeth and have the potential to become aspirated or swallowed.
