Hello there ,
Thanks for writing your query,
is nothing but bacterial infection that spreads to the deeper structures of the tooth and involves the tooth nerve
tissue leading to pulpitis
When the tooth is grossly decayed, it becomes weak and gets fractured.
infected tooth often radiates pain to the surrounding structures like ear , head and neck area.
symptoms of fever and lymphadenopathy
are common .
We can save such infected tooth by root canal
procedure, provided the periodontal status of the tooth is good. That is, if the tooth is not mobile.
Root canal procedure disinfects the tooth by removing the infected nerve tissue and the root canals are cleaned,shaped and filled with permanent restorative material.
Once the treatment is completed , the tooth can be restored by a post and core preparation with a prosthetic crown coverage.
or if the prognosis is poor , the tooth can be extracted surgically.
i hope this helps ,
