Can zoom bleaching change the color of your dentin and or just make it appear whiter?

Bleaching techniques, such as Zoom Whitening, Polar White, etc. are great at bleaching the outermost layer of your teeth, the enamel.  However, bleaching agents can not change the color of your enamel.  If it is in-fact your dentin that is appearing more yellow than your enamel, then I would highly recommend porcelain veneers.  Veneers are extremely stain resistant and they allow you to choose your shade of white before they are placed.  Whitening is a great temporary fix for those with minor staining issues that don't mind bleaching their teeth every few months, but for those who want white teeth without the worry of continuously whitening, then veneers would be a more permanent solution.  When veneers are done properly, you can expect them to last 20-30 years before needing them redone.  Good luck and I hope this helps.

Teeth have 3 distinct layers: enamel, dentin, and pulp. Any sort of tooth bleaching generally only has an effect on the outermost surfaces of your tooth enamel. Zoom! is barely different from many other clinical-grade bleaching products available.Additionally, as you've noticed, the enamel layer may be extremely translucent, almost glassy. Unfortunately, bleaching dentin is not typical, and if anything, will feel quite painful if the bleach reached dentin, since dentin is extremely sensitive to temperatures and acids. That being said, bleaching products have the most profound effect on people who have more opaque enamel that may have been stained by food and drinks, smoking, or other similar causes.
