Q. Hi Doctor I visited the dentist for a filling and during that my dentist told me that my upper left first incisor looked dead to her. When I was young I had braces and probably that did some damage. There is a light vertical crack mark on the tooth but i used to feet no pain or discomfort. My dentist took an x ray and performed an hot-cold test on the tooth and since I had no sensation in that tooth, she suggested that I root canal it to prevent damage to it and the neighboring teeth. After the root canal which was performed a year back, I am noticing that the teeth is turning dark — I am not too sure if I should get it crowned because it is the front tooth and I have heard people complaining that the white enamel on the crown sometimes just breaks. Is there any other way I can whiten the tooth? I also want to point out that when my dentist performed the root canal, I had no pain even when no anesthesia was used. So I also have doubts if the root canal at all was required. I am very worried. Please advise me. I shuttle between Mumbai and Delhi for work, and if you are aware of any good doctor in these cities I would be very obliged if you could pass me their contacts. In case age has anything to do with teeth, I would like to tell you that I am 25yrs old. Thanks
