Dear Queenie,
A guy I know has really bad teeth. Some of them are missing and others you can see have a lot of decay. And he has really bad breath. He has asked me to go out, but there is no way I want to date him. What if he tried to kiss me?
Queenie, should I tell him to go see a dentist?—Disgusted
Dear Disgusted,
Tell him politely that you are put off by his bad breath and concerned that the state of his teeth could cause him some other health problems as well, and recommend your own dentist, making a point of telling him how well (and gently) your dentist treats you.
