I have had 13 mercury fillings replaced. 5 weeks later and a packet of pain killers per week, sometime 2 packets... I am so depressed , wish I had never removed my old fillings... Been up and down to dentist who can't seem to understand my pain! Unbearable, I am hoping after reading a few articles that this will settle down... Some people have said it took 4 months... Did yours come right, and if so how long did it take?
