The Zoom may work for you -- it will not likely make the discoloration worse. Sometimes if you have white spots on the teeth - those spots will be accentuated right after whitening due to the teeth getting dehydrated -- after the teeth rehydrate the bright spots will die down. You should find a cosmetic dentist and schedule a consultation visit. Together you can discuss different options like Zoom, or other whitening methods as well as bonding those areas on the front teeth. From the situation you describe, it should be easy to improve your smile.
