Teeth don't get white enough When the light doesn't give adequate results, you're asked to buy a tray for $25 The initial coating is done quickly but the second treatment is applied by a second woman who is more precise and does a better job

Worst experience ever

Didn't notice a difference on my teeth. They look exactly the same as they did before I went in for my appointment. They are not whiter. Not impressed. Location was a little shady, was a house with a dental chair. The two techs that performed the Zoom treatment were not very professional, I doubt they were certified. Unhappy with my purchase.
