i know there are probably alot of posts on teeth whitening i wanted to share this though. i have been using crest white strips for about 4-5 dayz twice aday and i have always had yellow teeth according to my sister and the other day she complemented me on how white my teeth were getting so anyone who is thinking about trying it should :) but i have now been having sensitivity and i was wondering if i use one in the morning and then one at night if that would help because i have been using one right after the other. :confused:

I hate whitestrips. I had to stop using them after 5 days, and my sensitivity lasted 6+ months. I saw a dentist twice regarding it. Even the wind would hurt them. Crst refunded my money but didnt care I spent over $250 bucks trying to alleviate the pain caused by their products. I never ever had a sensitivity problem before -like I could bite ice cream or popsicles w/o pain. Those stupid strips made my teeth sensitive to all that even 2yrs later. Call Crest and tell them. I even made a report to the FDA about the whitestrips.

The whitestrips have worked for me also, I really like them! I use one in the morning and one before I go to bed, but I still have sensitivity-- I think it's inevitable regardless of when you use them.

I know a lot of folks who have been whitening their teeth with Gly-Oxide (it was originally used in hospitals to clean the mouths of bedridden patients) in mouthguards. They get the 99 cent mouthguards (the kind you boil for 15 seconds & then put in your mouth to mold to your teeth) & then swab a bit of Gly-Oxide on their teeth & insert the mouthguard for 10-20 minutes. Gly-Oxide contains 10% carbonic peroxide, which is the same ingredient as the whiteners - plus it's a lot cheaper. And none of the people I know who have tried it have had problems with sensitivity - and several were concerned since they had sensitive teeth anyway.

I used Crest White Strips and my teeth have always been very sensitive. You don't have to use two a day. You can just use one a day and try using Sensodyne Toothpaste along with it. That's what I did. Also, I've been hearing about using Debrox Ear Drops with a mouthguard.

Obviously you've already tried them so this won't help..but it may help someone else. A friend of mine was getting the Zoom whitening done and the hygeniest was supposed to give him a sensitivity type toothpaste to use before the procedure as well as after. She forgot...and his teeth were lightened many shades so they were very sensitive.... but my point is that a flouride or sensitive toothpaste may help if used a few days before any whitening?!?! Using the strips back to back was probably too harsh. I've never used them so I don't know what the directions say, but I would think only once or twice a day would be the max?!?! I had mine done with custom mouth guards and solution and was only supposed to use it once a day. Also you want to stay away from anything with citrus or enamal eating properties. Your teeth are more sensitive during the process and little pores (that's the best way I know to describe it) are open so citrus will enter and eat the enamel and make your teeth hurt. Cola's the same thing. Anything acidic.

Whitening actually destroys your enamel. That's why your teeth become sensitive. It also destroys crowns.

Whitening does not destroy crowns. It doesn't even affect crowns.

My professor explained that it did in fact ruin them. Teeth whitener is some pretty harsh stuff.

Really, not to argue, but people don't put bleach on crowns, because they can't be bleached like regular teeth.
