Yay, broken tooth!
Yes, it is silly to cheer on the demise of one’s denture, but this particular molar had been thrice fractured, the last of which did not result in a clean shearing: the tooth was broken and down, but not out.
Last night, after days of worrying with my tongue, upper molars, and, finally, fingers, I managed to root out that miscreant fragment.
Of course, now there’s a space where the tooth had been, but since “dental health” is apparently not sufficiently healthish, any fixes are not covered by my insurance.
I will thus remain unfixed.
