Crest Whitestrips Renewal

Strengths: Easy to use, quick results

Weaknesses: feel "loose" on the teeth.

Summary: So far, I have been satisfied with this product. I saw results very quickly. They are easy to use, however, you need to adjust them slightly towards the end as they do feel like they are slipping off the teeth. I'd purchase again.

Great whitening, time consuming

Strengths: Unparalleled whitening power for a home whitening product

Weaknesses: Does take a decent time commitment to complete

Summary: The new "age defying" crest renewal white strips are the most powerful ones they currently offer. The whitening performance is very good for a home product and is certainly noticeable. The downside is that it takes a big time commitment for finish the program, with 2 30 minute applications per day required, for 10 days. Compared to some other "5 minute" treatments it's a lot.

Also the Crest whitestrips are not the easiest to use and deal with, often they are hard to separate from the backing. Compared to the new dissolving Listerine strips this is quite a pain.

Whitens well but makes teeth sensitive

Strengths: Whitens pretty well with a full treatment

Weaknesses: Makes teeth feel very sensitive with regular use. Takes 1/2 hour per treatment

Summary: These are the strongest whitening strips that Crest currently makes and they do a good job whitening teeth. But it's almost too much because they made my teeth very sensitive if I used them regularly and I had to take breaks in the treatment. The sensitivity was very annoying overall and made me wonder if it's worth it. Also each treatment takes 1/2 hour which doesn't sound like a lot but it's not easy to fit in that much time with no drinking or eating and remember to put the strip in at the same time. They need to work on reducing the treatment time while still providing the same whitening benefit.
