When you get swelling or pain on a tooth that will need a root canal ,it could be too late to save the tooth and you might need extraction.
I highly recommend to get a consult and define the necessity of root canal and act on it ASAP.

The short answer is the concern for future flare ups and pain. A necrotic or dead tooth is a breeding ground for bacteria and not the good kind. A root canal not treated could remain quiet for some time or could start to hurt when chewing or become tender or sensitive to heat. I understand the hesitation and it does give you the flexibility to choose when to treat the tooth. But a dead or dying tooth will not heal itself so it is only a matter of time until trouble comes to town.
You should ask your current dentist your question to see what response you get. And you deserve to know why the tooth “ needs a root canal”. I routinely show my patients xrays and explain what is going on. There are times if a patient has no pain I may wait but that can only be determined with proper diagnostics.
All the best
