Q.
I have always had a lot of problems with my teeth and in the last couple of years, I have had root canal treatment on my front teeth. The treatment has considerably darkened my teeth to the extent where I am now very conscious about smiling or showing my teeth. I am seriously thinking of having my teeth whitened but I am worried because I have heard it can sometimes do more damage and my teeth are not in very good condition as i have quite a few fillings etc. Do teeth have to be in good condition to undergo the whitening process? I am also not sure if the whitening would work because it has been caused by root canal? If you could offer any advice, I would be very grateful. L.
