Can I use two Crest Whitening Strips on my top row teeth?

I have been drinking more and more coffee lately - and the colour of my teeth is beginning to become spoiled. I was wondering if I could use two whitening strips on my top row of my teeth? It would be really awkward for me to have white teeth at the front, but to have sullied teeth in the back. Is it safe to use two at equal time? Can I also do the same for my bottom row? Oh, okay thanks Sarah! Other peoples' experience would be much appreciated.
Best Answer: I have a really broad smile and I used two on my top teeth a few months before my wedding with no problem. Maybe somewhat bit more sensitivity, but nothing unbearable that didn't go away.

Answer:

Will braces hurt more than my spacers?

Hi!! I use to look terribly awkward whenever people see me smiling. I was having vastly bad teeth, I really needed a teeth whitening product. One dentist friend of mine told me about http://www.ivory-white-teeth.apooz.com and http://www.teeth-whiten.apooz.com and got excellet results out of it. High recommended. Best section is that both of these are currently providing ONE MONTH FREE TRIAL to use. So get it now and put it to use. You will see the results within first week of using it. Good Luck.
