I'm quite certain everyone and their dog knows this one, but I'll just say it anyways. Gargle salt water. I hope you're not in too much pain, although I'm pretty sure you must be.
Actually, no pain at all. All my teeth had root canals (due to the acid reflux) so it's just a dead stump. I'm more concerned about keeping my tooth clean.
I think I'm just going to drop it in some milk. But thank you everyone for your advice! I appreciate it.
