heyy i have a question about crest whitestrips i can always get the upper strip to stay on my teeth it. My cousin uses and lower ones seperately so that it will stay on better. The consultant who introduced it to her said to wear the upper ones but the bottom usually slips is there anything i can do to make it stay in place??? thanks! So use the upper ones first till all are it worked for her.

I thought it sounded weird, but months after using it up. Her teeth was white for about six strips are finish, then use the lower ones.
