Most effective professional tooth whitening availiable?

I am going in 2 weeks for my Zoom Whitening and my dentist told me that you don't always get that "Hollywood smile." Does anyone know if there is any professional teeth whitening better than Zoom? Thanx

As a dental professional, I can attest to the fact that the ZOOM Whitening system is arguably the best process available at the present time. Results of course, vary... but that's the case with almost everything. The only way to get a true "Hollywood Smile" would be to go with veneers--- but the price is of course considerably more than Zoom. I think you're making a good choice... Good Luck to you!
