Ah I see, sorry to hear that... Yeah, major advances in dental care have mostly been responsible. My dad's still got a couple of his own teeth left at 86, but his problem is receding gums. I've still got all mine. and they're good and strong.
I know that 54 isn't all that old, but so far I haven't 'fallen apart' like a lot of people my age and much younger!
