No one likes being given the news that they need root canal treatment. "But I just wanted a filling." Or "Why can't you just put a filling in the tooth?"
There comes a point where teeth cannot be "fixed" with just a filling. This is because when bacteria reaches the pulp tissue inside a tooth, it is diseased and infected, and infection goes into the jawbone. The infection needs to be removed and so the alternative to having the tooth extracted is to have Root Canal (endodontic) Treatment. When there is enough tooth structure remaining to restore, we do usually recommend saving the tooth and avoid extraction and loss of the tooth.
Root Canal Treatment is a delicate procedure to find, disinfect and seal the chamber system inside the tooth, typically completed in three stages.
The emergency appointment is usually when the first stage is done and pain relief occurs very soon after. Over a period of several weeks, the tooth carries a special medicament inside and the next stages are completed. The infection clears and then the root system is filled up to prevent future bacterial contamination.
The tooth is more often than not very weak structurally and is then finally reconstructed with a protective restoration to specially seal the work, as well as protect and restore your tooth. Most commonly, this restoration would be a crown.
