My teeth have always been more of a yellowish shade than white so when I got a $7.00 off coupon for Crest Whitestrips and they were also on sale at Kmart, I bought a box. (I think they ended up costing around $26.00.) It's a 2-week system where you apply the "tooth whitening gel containing peroxide" strips for 30 minutes twice/day and your teeth should be noticeably whiter in two weeks. I keep checking mirrors and I'm not sure they've gotten "noticeably whiter"-- just paler yellow, IMO :imbar and I'm nearly at the end of the treatment.
Anyone else ever tried these or had your teeth professionally whitened? I always use a whitening toothpaste (Colgate or Arm & Hammer) but never noticed much difference. Any suggestions for brightening my less than pearly whites that won't cost an arm and a leg?
