After spending the whole weekend with a crownless tooth (fortunately it didn't hurt, as long as I chewed on the right side), I went to the dentist on Monday morning. This time, he noticed gum tissue starting to grow over it, and had to numb me up and cut it away. That wasn't pleasant. He may have also scraped the tooth down a bit, because I could taste tooth enamel dust, also not pleasant.
But finally he was all done and my crown was back in. The rest of the day, my mouth was sore on the left, and chewing, even just on the right side, hurt on the left. I had soup for lunch. But yesterday I recovered enough to have a burger and fries. Yum!
And I noticed something encouraging: the previous time the dentist had put the crown back in, it rode a little high, and my bite felt a bit unnatural, like one of my teeth had suddenly become too big. This time around, I don't have that; my jaws fit together perfectly! So hopefully it'll stay in a lot longer this time.
(It will also help if I can remember to brush every day. I slacked off recently, and that probably contributed to the problem. Thing is, brushing isn't fun; no matter what they do to toothpaste, it still tastes like fucking TOOTHPASTE. Bleh.)
