What is a Root Canal?
Root Canals are a measure to ensure that your damaged and decaying tooth does not cause further problem for your mouth in the future. Your nerve and pulp will be removed and this will help prevent any other damage from occurring. The inside of your tooth will be cleaned and sealed to prevent any further infection.
Your tooth will be able to function normally without the pulp and nerve and you will be able to go back to your daily routine without the pain and other damage caused by dying and decaying teeth.
Why does the pulp need to be removed?
The reason that the pulp needs to be removed is that the damage has already been done to that tooth. You need to make sure that there is no spreading of the issues to other places. One problem that could arise without treating the pulp would be bone loss, drainage to other parts of your mouth, as well as swelling inside your mouth and face.
