I had to get a root canal about two years ago because of an inflamed nerve. The tooth has turned an ugly yellow color, which is making me very self conscious. My dentist told me that whitening it will weaken the tooth. What are my options?

Ideally, it would have been best to prevent the discoloration to begin with, though this is not your fault. Many dentists aren’t aware that if you carefully remove all root canal filling materials and cements from the inside of the crown of the tooth, the tooth won’t discolor for maybe ten years. We are seeing cases, where the dentists didn’t do this and discoloration is starting even within the first year.
However, now you’re stuck with this discolored tooth, so let’s figure out your options. Your first option is teeth whitening. If you bleach only the crown of the tooth, and prevent it from getting to the root, then your teeth will not be weakened, but you’ll have to make sure ahead of time your dentist knows how to accomplish that.
Your next options are to either get a porcelain crown or a porcelain veneer. I am guessing you’d want the more conservative treatment. In this case, as long as there are no large fillings in the tooth, that would be porcelain veneers. They will actually leave the tooth stronger. You would only need one veneer, unless there are other things you want to change about your smile. A dentist may try to suggest there really needs to be two of them, but that is not the case and reflects a lack of confidence on the dentists part of how to match the color and translucency.
If there are other issues with the tooth, such as fillings, then it might be preferable to do a crown. With porcelain crowns, you have to shave the tooth down quite a bit, so if the tooth is otherwise healthy, this would be my last choice.
With either of the last two options, you’ll want to make sure to go to an expert cosmetic dentist. Matching another front tooth, and making it look natural takes a lot of artistic talent and technical expertise. Don’t just entrust this to your average family dentist.
