The age of teeth crumbling

I seem to have arrived at the age of unexpected teeth crumbling, just due to decades of wear and tear.

Maybe that sounds a bit dramatic - but a couple of years ago, a fine wedge at the back bottom edge of one of my front teeth disappeared.  Not a big deal, as it is not visible from the front and causes no pain.  The dentist wasn't too concerned: it's just that the edge of that tooth feels different to my tongue now.  The dentist smoothed the new sharp ridge edge, and no further changes have happened there.  It would not be completely surprising, however, if some further damage advances there.

This morning, a sizeable corner of a bottom molar broke while I was eating some particularly hard toasted museli style cereal.  The tooth had had substantial repair before (maybe 30 years ago) but even so, I like my teeth not to have sudden gaping holes in them.  There was no pain, just a bit of sensitivity.

A repair has been made already, although of a type the dentist said might last a couple of months, or a decade, she couldn't tell.  A more permanent fix would be a crown (my first, as it happens.)  I'll be concentrating chewing on the other side of my mouth for some time, I think!
