Crest 3D Whitestrips, Professional Effects with LED Accelerator Light, Whitestrips 3D White, Teeth Whitening Strip Kit, 1 Light & 20 Treatments (Each with 1 Upper/1 Lower Strip), 40 Strips

It's a great product that works. I left the strips on for 2 hours. And my teeth were so white, I decided not to use the light. I drink 3-4 cups of strong coffee everyday, and they are still really white (after one application over two weeks ago). My gums were a little sensitive after 2 hours, but that only lasted a few hours after usage. Just be aware if you leave on more than 60 minutes. Then brush and rinse really good. I use their "brilliance" tooth paste as well.

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.

Really effective whitening product. My toddler asked if I painted my teeth, I’m assuming because they looked white. I’ve only done 5 treatments. This does make your teeth really sensitive, so I is usually don’t do treatments on back to back days.

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.

It works. It was a recommendation from a friend. Now my hygienist uses it too. People are always commenting on how white my teeth are. I am in the maintenance phase. My only issue is the light. I have had several stop working. I purchased another kit and I use that light instead (more intense, connect thru my cellphone). HONEST REVIEW!!!

Best teeth whitener Ive used. Makes teeth much whiter for a fraction of the cost of dental whiting. Although I haven't done dental whiting before just these do it at home versions.

The product works perfect and it has to be use the way the box advise otherwise it was be feeling uncomfortable. It works.
