A root canal is needed when the nerve of a tooth has become damaged by injury or infected by decay. This procedure saves the tooth and can help restore it to natural function.
For the first step, your doctor numbs the area, and then creates an opening in the tooth to access the root’s interior. Next, the infected tissue is removed and the area is flushed and cleaned. Lastly, the root is filled with a special sealing material, and the opening is filled and sealed.
The tooth has now been saved from infection or fracture and can be restored to its natural function with a permanent filling or crown.
