I'm still confused. There is enamel in the bones _between_ the teeth? My
x-rays showed very light areas defining the _bone_ not teeth above the gum
line _between_ the teeth (but in between the roots), which correlated with a
tightening of the teeth themselves. Interproximinal sounds more right than
the term I used. But that's _enamel_?

The teeth themselves didn't show remineralization (that I know of) but only
the bone mass of (I assume) the jaw itself.
