Review: These really do work... - I'm not one to leave reviews unless the product is outstanding or exceptionally bad. I'm not being compensated by anyone for anything. I'm just a guy... I am happy to tell you, these work great. I didn't think to take before pics but to be honest, in the right light, my teeth looked orange. I guess that's what I get for smoking for 45 years & drinking coffee for 40 years. My teeth are sensitive & I've had bad reactions to other products of this type over the years. I started with the gentle kit & used one set every other day. I wasn't happy so the following week I bumped it up to the medium kit & another gentle kit. I alternated the gentle & the medium with a one day break in between. That was about 2.5 weeks & my teeth look great. I've got plenty left over just for brush ups. These are great.
Review: They work. Easy. Gentle. - Got these before a wedding. I’ve had my teeth whitened before and find these good for maintenance. Worked well. Gentle. Didn’t irritate gums. Only negative is the trays are quite small. Had to push them down so they’d fully cover my front teeth - top and bottom. Other than that I’d buy again.

**Q: How does Opal by Opalescence teeth whitening work?**
A: Our teeth whitening works by removing stains and discolorations from the enamel and dentin. The active ingredients in our whitening gels oxidize the discolored molecules deep down in your teeth to remove stains and whiten your smile comfortably.

### ⭐⭐⭐⭐⭐ Fantastic quality, and works!
*by K***A on September 25, 2024*

I’ve tried a lot of “white strip” brands, and these have been hands down the best. I was most impressed that they whiten all surfaces of the teeth, including between the teeth, which white strips can’t. I had zero sensitivity AND better results than I ever have with any other brand. The little trays suction around both sides of the teeth and the gel reaches all of the nooks and crannies. Highly recommended!
