I really wanted to try Crest Sensi-Stop Strips because I have really sensitive teeth. I knew I would be able to tell right away if it was working because my teeth are sensitive every day. After using the first strip, there was no relief and I was disappointed but I read in the instructions that it could use another strip the next day if you still have sensitivity. Well, I did not want to wait until the next day so about an hour later, I went ahead and used a second strip. Now, this time I did notice a tiny bit of relief. I was surprised by that but still wished it were stronger. I think the product works but you probably will have to use more than one strip for each tooth. I did not like the fact that these are so short either. I expected them to be the length of the Crest White Strips or other strips like that. These are more like a small patch that covers about two teeth or maybe three small teeth at the most.

I think these strips could definitely be stronger since two gave me a tiny bit of relief but with one, I never noticed any difference. I plan to use a third strip to see if I can make the sensitivity go completely away. I do like the fact that these are supposed to last 30 days. It hasn't been a month yet so I don't know if that is true. I still think these can be good for people who don't have as sensitive teeth as mine. Just wish they made each strip stronger or longer so they covered more teeth. These can be quite expensive for just six little strips (patches) so I feel like I should get more for my money. Especially if I have to use two or three strips just for one tooth. It starts to feel not worth the money. Nonetheless, this product should work decent for people who do not have as much sensitivity or their sensitivity is minor.
