Just finished eating, noticed a sharp edge on the right side of the upper left side of my teeth, towards the back. Apparently a piece of a tooth broke off... and I must have swallowed it, because I didn't see it. It might have been related to my fall the other night, when the cat ran out in front of me, being it's on the side of my face I landed on.
Called the dentist, have an appointment for 10am tomorrow morning.
