Filling gap after tooth extraction

[worrier]

I'm 73 and my lower back tooth needs a complex extraction. It doesn't hurt but a dentist said it's beyond repair and shows decay. I'm procrastinating about having it extracted due to cost and fear of procedure, but I think I will have to resign myself to it sooner or later. When it is extracted, will I need anything to fill the gap, such as an implant? Or can the gap just be left?

It all depends how it affects you afterwards. If you can still eat comfortably, then probably no need to replace it.
