I have "a sizeable hole" in my tooth! Dang drat and blast! My first one ever! The hygienist said that I have been taking good care of my teeth and gums and the cavity was probably caused by a little chip in the tooth.
Apparently "good care" includes not going to the dentist and/or flossing for three years.
Heh heh heh. Jokes on you, FaceMask.
