Well, I did lose a tooth back in 012 due to it's dying (who knows why?). Other than that, we get our teeth cleaned and checked every 6 months. Had a crown put on about 10 years ago. Has held up pretty well. I had toyed with the idea of getting an implant to replace the dead tooth that got yanked, but between the cost and hassle, I decided against it. At 75 I don't really care too much if people catch a quick glimpse of a missing tooth occasionally. Doesn't affect my eating.
