Crest3D Whitestrips, Radiant Express with LED Accelerator Light, Teeth Whitening Strip Kit, 40 Strips (20 Count Pack)

Wish I had taken a before photo because my teeth are noticeably whiter after using these. I did not have any sensitivity using these strips, and followed directions exactly. I tried a professional whitening treatment from the dentist (with the custom fit and $450) but didn’t see much of a change. I started asking around to see what people did who had whiter teeth and they all said crest white strips. No joke, my teeth are much whiter with this product than the one from the dentist. Also the whitening has lasted. Three months later and I still have a much whiter smile. I am a total convert and will use this at least twice a year for maintenance - might do quarterly. Ten out of ten. I tried the 45 minutes without the light and the 1 hour with the light. The version with the light was more effective. I also wondered if the front teeth would look whiter than the back ones given the length of the strips but it’s not an issue. They figured out how long the strips need to be. I did find that if I dried my teeth first with a tissue that the strips stuck better and stayed on better. I also tried this during work hours when working from home but it changed my speech a tiny bit when I took calls (kind of like a lisp) so I now use these either before or after work.

I noticed a difference right away. No wonder it’s always sold out. I highly recommend. It works great. It may leave my teeth feeling a little sensitive after now and then but it doesn’t last.

These are the ultimate they’re very very good. I saw a difference within the first week. I’m getting ready to order more. I find them better than going to having them done professionally a lot more economical easy to use in great results.

They definitely work wonders for whitening. I have used many whitening strips from crest with mild sensitivity to my teeth (as expected). However, these cause extreme sensitivity, I assume due to their whitening strength. Works great but I spread out application between 48-72 hours & use a sensitive reducing toothpaste.

These strips work great! I saw results after just a few uses. The light makes a big difference—my teeth looked brighter way faster than with regular strips. Easy to use too!

These really work! I saw a brighter smile after just a couple uses. The LED light gives it an extra boost, and the strips stay in place well. Super easy to use—love the results!

Works well. I use it weekly. Be careful about the expiration date. I purchased in June 2024and when the light stopped working in October I noticed that the expiration date was also Jun 2024. Amazon sold me a box that was essentially expired when I purchased it. The strips were fine but the light was useless after 4 months. Check the expiration date on delivery!

This is my second time ordering these strips. I have never felt any discomfort with these, as I have with other crest strips. Maybe it’s using the light provided as well? Not sure - but they work without the sensitivity, at least for me. And your teeth will be whiter!!!
