Well, now my whole upper left side of my gums hurt and I keep getting headaches, and on top of that, the crown feels like it will fall out every time I try chewing on it or if I drink water, it feels like the water is going beneath the
crown. It also keeps hitting the bottom
tooth when saying specific words... What could this be? What should I do? My dentist said that he would only shorten up the bottom teeth and that the crown was a perfect fit...
