Crest Whitestrips are an effective product for whitening teeth and have been for all these years. However, along with the other reviewers, I do not have sensitive teeth but I cannot use these for 30 minutes a day as recommended for days in a row. My teeth get too painful that I can't even sleep. I suggest every 3 days, and you will have white teeth! I love white teeth so I don't mind paying this much for them at Walmart and coupons for $7 off sometimes come with the Sunday paper

Its nice having white teeth but maybe try a less harsh one because it makes your teeth feel like there's a cold breeze blowing on it constantly. I could NOT use it every day for a week. I skipped because my teeth hurt so bad.
I love Crest Whitestrips. The results really do show after the first few strips. However, my teeth were very sensitive after the first few strips that I had to take a few days off from whitening. The sensitivity went away, and I would definetly say the pain was worth it.
These are the 7 day for 2 hours a day strips. Rated 5 in Crests 1-5 of whiteness.
- Very Effective
- Whiten quickly so if you're in a hurry these are the ones.
- Stick very well to teeth
- Good length on strips too to get the side teeth
- I don't think you need to use all 7 strips in a row. I think I'll just use 3 or 4 and then repeat in 6 months times.
- I don't have sensitive teeth, I can bite into ice cream. And there is no way I could use these 7 days in a row. The day after teeth are uncomfortable, perhaps slightly painful. I also prepared using Colgates Sensitive teeth toothpaste. By the 3rd day the feeling has gone.
- They're not cheap.
I used mine on Monday and then again on Sat and still I have the next day feeling. So if you have even slightly sensitive teeth I really don't recommend them.
