These are a coffee/tea drinker's dream come true. The last time I used Crest Whitestrips, I had to stop because of teeth sensitivity. This time, I noticed a little bit of sensitivity on the first day, but it was fine once I gradually introduced it (i.e. I used it every other day for 3 days, then started using it everyday). With each use, your teeth will be visibly whiter. Tip: in order to keep these in place and stop yourself from swallowing the gel, try lying down after you put them on.

I received the 3D Whitestrips free to try and review. I have tried quite a few white strips in the past and found compared to others they performed quite well. With any whitening products I typically prepare for a bit of tooth sensitivity and usually leave a day or two between treatments. With the Noticeably White strips I didnt notice any increase in sensitivity which was a pleasant surprise. After only 4 treatments (spaced over 1 week) I noticed a significant improvement in the coffee staining. I did find that the longer lower strip didnt want to stay in place at the ends but compared to the older style white strips they stay in place on the front of the teeth quite well with only the odd adjustment needed. The treatment time is only a half hour so popping these on while I got ready for work was super convenient. Overall I would recommend! [This review was collected as part of a promotion.]
