Thank you ginnie, for your response and story. I did have two root canalled teeth that got infected and had to be pulled. So I'm not a fan of root canals, but I also don't like losing the last tooth that helps me chew food properly.

So, I'm in a difficult position. I still have two other root canalled teeth and I'm not happy about that, but they seem okay for now.
Anyway, I need to decide rather soon, so I hope to hear from others who might have different experiences. I wouldn't opt for implants either, too intrusive. If I get a tooth extracted, I don't want to put something else in there!
Thanks, Gretchen
