Root canal - Wikipedia, the free encyclopedia |
 | | The root canal is the hollow area at the center of a tooth. |
 | | A root canal, coupled with internal tooth bleaching, is also used to fix teeth that have flened due to infiltrarion of decayed soft tissue into the dentin in the teeth, most often seen in frontal incisors that have been injured through a sudden impact. |
 | | For patients, root canal therapy is one of the most feared procedures in all of dentistry; contrary to popular belief, however, root canal treatment is usually painless due to effective pain control techniques used by the dentist while the treatment is being performed and the (optional) use of pain control medication after treatment. |
