Why are my gums swollen with bad smell from drilled teeth?

Hi,

Welcome to icliniq.com

I have read your complaint and the relevant details. My first question would be did you not visit back the dentist after the filling has been done? Because you are already informed that it has a split deep under which means the treatment cannot be just a filling. I wonder why the treatment was ceased half-way. The ideal treatment plan for a split or fractured tooth should be as follows. Depending on the depth of the fracture it could be root canal filled and fixed with a crown on top. In case of deep fracture where root canal cannot proceed the tooth has to be pulled out under local anesthesia. Now the swelling in the gum and the bad odor is because the tooth got decayed heavily and it is over a year. This is called necrosis similar to a dead tooth. The burning sensation and the white coating on the side of your tongue are because of the rubbing of the tongue over the sharp edges of the tooth. Now the only choice is to remove the tooth and since the friction causing factor is removed the tongue will get back to normal in few days after extraction.
