Dead tooth - home custom tray whitening? I want to whiten all of my teeth. (Photo)

Thank you for your question.Here are your options, regardless of cost, starting with the ones that will give you the best resultsRe-doing the internal whitening and simultaneously whitening all your teeth in trays (typically overnight). Following all the diet adviceRe-doing the internal whitening and then after a wait, whitening all your teeth in trays (typically overnight).Placing gel only in your dark tooth with home tray whitening for maybe 2 weeks before placing gel for all the teeth for a further 2 weeks. This will show you how white your dark tooth can get. If you are happy with that colour, then you can avoid the internal whitening this time.Good luck and kind regardsThomas Dey, BDS, MSc

Internal bleaching is the best thing for the dead tooth. Home whitening will work on the others but will probably not give you the result you want for the graying tooth.

external whitening will practically have no effect on your discolored front tooth due to a depth of the problem. And unfortunately Doing internal whitening also requires repetition of the procedure.  If you try to widen all of your teeth as you intend then you might only aggravate your problem since it will emphasize the grayness of your discolored front tooth by making surrounding teeth whiter. My suggestion:  apply external whitening as you want then wait a few weeks for a final shade to settle in then see your dentist to place a veneer on a discolored tooth. This will take care of the problem for a long time. Good luck, dr. Daniyar
