question: Hi doctor, Recently, I have been under tremendous amounts of stress and following that, I have started to notice my bottom front tooth has started to feel slightly abnormal. It sits further back from the rest. Recently, it feels like something has trapped between the teeth and throbs now and then. The tooth looks to have receded slightly, but my dentist did a deep clean and removed the enamel months ago. The gum looks fine and there is no swelling or redness. It did bleed slightly this morning, but not for long. Please help.
