Viruses in all this are not impacted by oral hygiene. I don't mean you can let you mouth go to hell in a basket, because there will be tons of other issues develop that will make your life miserable. But viruses are not impacted by anything that you can do hygiene-wise. ALSO getting back to your original post, be sure that if radiation was part of your original treatment, that anyone thinking of extracting a tooth in your mouth knows about it, and is up to speed on things. Even this many years out, you will still have healing issues, and if it can be saved by crowning that is a way better solution. Look into 02 treatments if it has to go.
