My tooth crown accidentally fell off, after 4 years I guess.
Since I moved to other place, I visited nearest dentist and got it put back... But it didn't last at all.
How fucked is it? Considering those ass-handed 'dentists' used UV-curing filler for some reason (I guess it is visible on pic), and had cut crown pretty significantly...
Dunno, it seems just wrong to me, some of filler should be cut, and post (or how this shit is called) will be exposed more, thus there will be more surface for adhesion, and I guess new crown is requires, since this is pretty fucked up now I guess.

(I'm sorry if this pic is somehow disturbing)
