I recently purchased teeth whitening from my dentist. I had custom trays and was informed to bleach overnight. after a couple of days my normally even teeth became a bit whiter but much more uneven. I was away on business so called the dentist and they said to keep going and it should even out. But since I was not at home near my dentist i didn’t want it to get worse especially on my front teeth. My dentist suggested i continue on one back tooth and see what happens. So i continued on one tooth for about a week, but the uneveness did not go away so i did not continue with the bleaching. When I returned a week ago to show my dentist, and return the kit she said I was correct to stop and that she would call the company who provided the bleach. They said this can happen sometimes. In any case, she said there was nothing that could be done and to leave it and not use whitening toothpastes. I am now left with patchyness which I am very aware of and bother me and miss my normal teeth and regret starting this process. Will the bleeching eventually fade and go back to how my teeth were before or am I stuck with this uneveness? It has been four months since I stopped bleaching and I don’t see any fading of the patches that are whiter than the rest of my teeth. Can you please advise? Is there anything I can do without continuing to bleach b/c i am worried to continue as worried it will get worse. is there another treatment? My dentist thought it was more likely that this was something under my teeth that has come up (don’t know if it is calcium deposits) as a result of the bleaching than uneven bleaching b/c they were custom trays. Please help! Thanks
