hi,I had recently gotten one of my back teeth fixed at the dentist's (my tooth was chipped).and now the whole (right side) top part of my gums hurt. The pain comes and goes, and it sometimes gives me a headache. I'm not sure if the pain is due to the tooth, because I had gone to a different dentist and he had told me that the tooth the first dentist had fixed was "defective"and there was a small cavity on a tooth right next to that one which was in the back of the tooth. when I went back to the first dentist to get my tooth fixed (cause I didn't want to dish out another $200 to get the same 2 teeth fixed), he told me the chipped tooth that he fixed looked fine to him, and he was just going to fill the cavity of the other tooth. now it's been like 4 days and the pain in my gums is still there.help!
