Dentist begging the patient: Could you help me? Could you give out a few of your loudest, most painful screams? Patient: Why? Doc, it isn't all that bad this time. Dentist: There are so many people in the waiting room right now and I don't want to miss the 4 o'clock ball game.
Then there's the woman who goes to the dentist. As he leans over to begin working on her, she grabs his balls. The dentist says, "Madam, I believe you've got a hold of my privates." The woman replies, "Yes. We're going to be careful not to hurt each other, aren't we."
A dentist friend of mine had a T-shirt which said on the front: Let me put my tool in your mouth... and on the back: ...and I will fill your cavity.
A man went to the dentist to get his teeth checked. While he was sitting in the chair being examined, the dentist said to him, "Have you done oral sex lately?" The man replied, "Why yes, I did this morning actually. How could you tell? Have you found a pubic hair stuck in my tooth?" The dentist says, "No, not quite. You've got some shit on the end of your nose!"
