Do the crest whitening strips really work?

Question

i was just wondering if i should try the crest whitening strips, has anyone ever used them...are they worth it? do the actually work? if so how long does it take and how often do i wear them? thanks =]

Answer 1

They will help a little bit but the problem with the commercial whiteners is they contain peroxide which is a bleach but it also changes the pH level in your teeth so they can end up quite sensitive to hot and cold.

The best thing to use thats very inexpensive is a $2 box of plain old baking soda!  Brush your teeth with that twice a day (it has a salty taste) and after you brush well with the baking soda, give them a quick going over with your regular toothpaste to get rid of the salt taste.  If you incorporate this into your regular brushing, you will have really nice white teeth.

Answer 2

I have tried using them, but stopped after a few times because of the taste. I used the quick dissolve strips, which don't dissolve quickly at all and they make your mouth foam as if you had rabies. I can't say if they work well or not though since I stopped using them. Good luck though! Hope they work better for you.  

Answer 3

YES!! =]

i got some a few weeks ago. I got the crest premium.. (there;s different types).

You wear them 2 times a day for 30 min and you really do start seeing a difference in just 3 days! i only had to wear mine for 4 and i was satisfied with the whiteness tey were!!
