its a new teeth whitening procedure that involves hydrogen peroxide of some sort with an intense light that activates the process. It takes a little over an hour & is supposed to improve about 6 to 8 shades of white.
its painless & comfortable from what i've read. I've heard its very effective but don't know anyone who has had it done & I don't trust the testemonials I've read.
Apparently its the new thing for the hollywood smiles
