Q. I had an infection at one of my front tooth and i needed a root canal.My dentist did it but i still have some of the infection left as i can feel it. Because of the root canal my tooth discoloured slightly and i don’t like it.I would like to whiten it but i don’t know where to go for cosmetic dentistry.Also the tooth is moving slightly and i am scared not to lose it.i don’t know if it is moving because of the root canal or because of the infection.Do you think I should pay the money for the whitening or what treatment do I need?pls tell me will i lose my tooth because of the root canal or is it just weakened?thank you
