Crest 3D Whitestrips Supreme Bright Boost Teeth Whitening Strips, 8 Levels Whiter, 7 Treatments, 14 Count (Pack of 1)

Good quality

The booster application was purchased as a 7 day treatment plan. It is not being used to extend the life of previous treatments, but as short term treatment. My only concerns about the manner in which these strips are marketed is that they indicate increasing brightening levels that correspond to how long the treatment lasts ( 7 days, 14 days, etc.) I've used these and the results were excellent. For those that might not have used them before, they might require an extensive treatment to get good results. But, over time, your teeth will not keep on getting brighter as they will reach a limit.

I didn’t realize that these whitening strips were to be used once a month not every day. Used my first set and saw a nice difference in how they made my teeth look whiter. I mostly had some staining from drinking tea. Looking forward to using the next set. Pleased with this product so far.

I noticed marked improvement in my colour of my teeth as it had less staining. I highly recommend and would by again.

The OG in teeth whitening! Its the only product I use and it has done a great job removing smoke stains from my teeth after smoking for 42 years.

I saw results after 3 applications.

I’m a few days in and everything is great! I love the product!

I haven’t tried these in at least a decade. I thought they surly would have improved the tech in that time. NOPE!These are a true pain to install and wear. The rectangular shape makes them impossible to fit over your rounded tooth line.If you suffer through the 7 treatments, think about it that’s 7 hours of your life, the results you get are barely noticeable.Pay for a real treatment and get real results. And get your life back.
