,HiI just recently got three cavities filled with white composite fillings. They are all on the lower left side of my mouth in the back. I am in unbearable pain. This pain is sharp and constant. It has lasted over  4 days now and is the worst at night. It even wakes be up from my sleep. What is going on? I had no pain before the filling. It took a while for the novacaine to kick in while I was having the procedure. I felt an immense amount of pain while my dentist is drilling.  The problem is I am away at college and have no time to head back home to go to the dentist.The pain has just gotten way to much to bare. What could this be?
HiT hanks for writing in. It can be due to two reasons:--caries might be very deep approaching pulp & requires root canal treatment rather than filling-there might be some high point in filling that is causing pinyon need to consult your dentist & get dental x-ray done to rule out the cause & get it treated accordingly.
