Tooth Whitening

So I got all four of my wisdom teeth pulled more than two weeks ago, and fortunately most of my mouth has returned to normal.

Except that in the bottom left part of my jaw, the back tooth is fairly sore, and hurts to touch. Also, there’s this strange bitter odor either coming from that tooth, or the hole from behind that tooth. It’s kind of milky, but it also smells and tastes like tooth enamel.

The sensation is most acute when it gets in my sinuses

What is it? And what could be causing it?

There could be some infection in the socket. It would be a good idea to have a dentist take a look at it, as it may need to be flushed out and possibly you also may need antibiotics. Good luck.
