Zoom Whitening didn't work
I had my teeth Zoom whitened a few weeks ago and I can't see any difference in the color of my teeth. My 2 front teeth are crowns and so they weren't effected by the Zoom and they STILL match all of my other teeth. I was thinking the crowns would look really brown once the others were whitened. I had planned to get new crowns to match my new shade. I am so disappointed. Has anyone ever heard of the Zoom simply not working?
