If you can't ask your dentist a question about the work that he has done in your mouth, he's not the dentist for you. That's exactly what happened here to me at Courtesy Dental... Instead of Dr Kern coming to a solution with me because my cavity he filled seemed to hurt worst than when i went i. So the dentist told me he'd refund me my money and don't come back. What a defeatist attitude! Well what happened to "hey let's take x-rays it may be another tooth? If you don't want to be questioned. Don't become a Dr..you don't talk to people that way just because you can. Very rude. Very unprofessional.
