I think our side of the family generally does have good teeth, though: messily-spaced ones, but fewer cavities than average. I think a lot of people who neglect dental hygiene the way you do would be much worse-off.

I obviously don't even know what a crown is, since I thought it was the kind of thing they do to 50-year-olds who are fearful of needing dentures. I've never heard of a crown or a root canal being done on somebody's baby teeth! Why root canal when you can just pull the damn thing and wait for a replacement to grow in??

(I'm sure there are reasons, blah blah blah. But...!)
