Yes, it is not necessarily a pleasant choice but a good one. Implants might be a better option, though the healhiest is probably partials if that is a viable option instead of full dentures. Leaving them in looks like almost a guarantee for problems to me. I think I have at least a couple myself that I need to attend to when money permits. In the meanwhile, live as healthily as possible and take some good natural immune boosters and anti-virals.
