question: Hi doctor, I have got problems with four different teeth. My front tooth is extremely sensitive and painful most of the time. A molar has had a deep filling that was done about a month and a half ago. Still, it hurts, and my dentist said it is nothing to worry. It feels as if shooting pains and sometimes, the pain spreads to my jaw, eyes and nose and I cannot eat on this tooth. Shall I opt for the tooth just to be extracted? It causes a lot of trouble. Also, my back two teeth have one complete filling that covers both teeth. It bleeds and hurts very much if I used in between brushes to clean my teeth, which my dentist advised me to use. I just cannot use that because it is too painful. I experience shooting pains in a lot of my teeth and the deeply filled tooth is the worst. If the tooth were to be extracted, is it possible to get a bridge? What is the longevity of dental bridges? Please refer the photos attached.
