Don't stress
Vincent, I noticed a brownish patch on the back of a tooth after my extractions.
It was the rear side of an upper #4 tooth that, until the week before, had had an upper #5 tooth behind it in the arch. The brown patch was revealed when the #5 (bicuspids) were extracted. I noticed it when I was checking out the sockets' healing and went to see my dentist the next week.
He was :
a) very impressed that I had found the spot
b) not at all concerned
c) unbelievably quick at fixing the problem
He did what I think he called an 'etch and bond', or something along those lines. I had braced myself (no pun intended

) for a traditional drilling-etc-filling procedure. What happened was more like a cleaning. It literally took 5 mins, he cleaned the area, applied a few ungenty-things, and I was on my way.
Piece of the proverbial
