This is about a guy who is terrified of going to the dentist, but when he gets a toothache his older sister gets him an appointment with the dentist she went to college with and they quickly form a friendship. In time that friendship develops into something more; although it takes time for them to get together. The guy has childhood trauma he's dealing with and the dentist hasn't had much luck in dating in the past. The series ends on a happy note for the main story and one of the subplots and the rest of the subplots all end of hopeful notes as well. The series does try to inject a lot of humor into it, sometimes that works, but sometimes it felt a little forced, but still well worth watching.
