I used the Crest Whitestrips and they did nothing really noticable at all to my teeth. They were a little bit of a pain. I think you have to leave them in for 20 minutes at a time. They also don't cover all of your teeth, they only cover the teeth that are readily visible in the front.
I also used that stuff you brush on out of a bottle - forget the name. This was a little more of a pain as you have to keep the teeth dry after you have painted them for about 30 or 60 seconds. This product also did nothing really noticable to the whiteness of my teeth.
I spoke to my dentist about this and got conflicting advice. The dental assistant told me to use the Crest Whitestrips as they use pretty much the same strength bleech. My Dentist told me that it is best to have them professionally done with the custom tray and bleech and so forth. I am going to have them done professionally so I will let you know how that turns out.
There is also the laser procedure that is fashionable right now. It goes for around $10,000 cdn and there are no gaurantees that it will work for everyone.
I think that the ONLY gaurantee for ultra white teeth are veneers (spelling) but that is extreme!!
