I have done the Zoom twice-most recently about 2 weeks ago. My main issue with Zoom and the band (my first Zoom was preband) is that my band doctor doesn't want us drinking out of straws, and drinking with a straw is encouraged after Zooming because it prevents staining. As I drink a lot of coffee and tea, this is a big issue for me. So, I sit here now sipping a glass of tea knowing that I'll just have to have Zoom more frequently. The process isn't all that painful. You do have to sit for about 45 mins with your mouth held open and stuffed with gauze, but it doesn't bother me at all. I would check around with dentists in your area. I paid a fortune the first time I had it done, but this second time, I went to a dentist who does free Zoom (does not include the trays--but you can follow up with white strips) with exam, x-rays, and cleaning--so mine was free this time with the services that were paid for by my dental insurance. Oh, and my teeth are usually sensitive for a day or two after, but it's not all that bad.
