I went to the dentist to get a filling in Tuesday. Ever since I have had unbearable pain. And could not get a hold of the dentist. He told me I would be sore but no pain In two days. I cant eat, drink, or sleep.  Could I have an infection? What could be wrong? It has no been almost 6 days since I went to him.
Thanks for your query, I have gone through your query. The pain in the tooth after filling can be because of the infection involving the pulp. If the infection is involving pulp and the filling has been done over that, there will be severe pain following filling due to increase in intramural pressure. Nothing to be panic, consult an endodontist and get the tooth treated with root canal treatment and crown. Meanwhile you can take a course of antibiotics like amoxicillin and metronidazole(if you are not allergic) for infection and for the pain, you can take diclofenac. I hope my answer will help you, take care.
