One of my lower molars became abscessed. It has an existing crown. I had a on this tooth about four weeks ago. They removed the existing crown because it was a bad crown . A few hours after the treatment, I began to have excessive swelling. I called the endodontist about this and he asked me to go in the next day. I saw him the next morning and he removed the to let the come out. After about 6 hours I became more swollen. I met with an as advised by the to get incision and drainage. I was told the infection had reached my bone. I was put on antibiotics and was advised to rinse with salt water as often as I can. After I finished the given course of antibiotics, I still had a small lump at the bottom of my jaw, under the molar, which I believed is still a sign of infection. Three days ago, the swelling had returned. The inside of my gum directly under the molar was hardened. My general dentist told me to give it a time. These may all be caused by the trauma experienced by my jaw, mouth and gum from the recent dental works I've had.
I am confused as to why I still have the infection and I am becoming extremely worried that the infection could spread throughout my jaw. 'Til now I am still swollen and tender.
Can someone please give me some information about my situation? I paid for a complete canal therapy but it cannot be completed until the infection is gone and I cannot afford to go to another dentist for a second opinion. I will be forever grateful for any information or advice you can give me.
