ZOOM teeth whitening Questions?

I need a second opinion on Zoom teeth whitening. Based on what you know about it, do you think it is effective? I have dark yellow stains in between teeth and something else "dysplasia" that my dentist mentioned, I have white spots randomly over more than a few of my teeth. Pretty much, I have different levels on staining on my teeth and wondering if the whitening will even the color out, even if some start out as a darker stain than others. And what's the peoper name for the white spots found on my teeth? Does whitening get that stuff out, since it's NOT really antibiotics/drink/food/smoking stains. Also been reading reviews saying Zoom is not effective for people white white spots. Also my Dentist says there is a "Life time gaurantee". Does that mean free retouching in office when necessary? Also, they will send me home with an at home bleaching kit after the procedure. It'll be $400...let me know your thoughts. Let me know your thoughts. Thanks.

The white stains are just calcium spots. It can be made from many different thing. Either hereditary, after braces, medication that your mom could have taken when she was pregnant, all kinds of different factors. Zoom does work very well. I dont know about the lifetime guarantee, but no you can not get free touch ups. Or I never heard of that. It works best on yellow stained teeth, and you should probably notice about 2 shades whiter depending on how stained they are. The whitening can not get the spots out, but it can dramatically reduce the appearance of it, by blending in the rest of your teeth. and yes you will get custom made bleaching trays to go home with, and that is how you will do your touch ups. i dont know what "dysplasia" is. Maybe it was dysthmia that you heard. That is just a space between your front teeth. Not saying that dysplasia is not anything, but i am just not familiar with the term. I have been doing zoom on my patients for 5 years, and they are always happy with the results.
