I went to the ER this past sunday (4.17.2016) because there is a tooth the very rear of my upper right side of my mouth that was hurting. I was prescribed motrin for the pain. I have a dentist appointment next wednesday, I woke up today and if I try to bite down, the tooth in the very rear of my upper right side of my mouth will hurt. I slightly touched the tooth with my index finger and it feels like it is chipped.
