It's important to work with a dentist, periodontist, and/or dental surgeon who is knowledgeable with post treatment dental care. To begin with, the decision is based, in part, by whether the tooth is on the top or the bottom, the bottom usually being the greater risk. And depending on the case, a cancer-literate dental specialist might order a root canal or cut the tooth off at the gum line. And with removal, where normally there might be an extraction, instead it will be surgical removal. And as for chambers, I've heard variations of how this goes.

What I wrote above are just examples of possibilities. I am not saying this is right for your case. But what I can say is you need to work with someone who is knowledgeable and experienced with post cancer dental issues. There is no way i would work with a regular dentist on this.
