If the inner part of the tooth (the pulp) becomes infected, it may be necessary to remove the affected tissue to avoid extraction and prevent further pain. The infection may have been caused by decay, a cracked filling, excessive wear of the outer layer or trauma to the teeth. If symptoms are present they may include pain, increased sensitivity, discolouration, gum tenderness or swelling.
The infected pulp is carefully removed under local anaesthetic and once the root canals have been cleaned, they are shaped and flushed with an anti-bacterial solution. At the next appointment, the root canals are filled and sealed. The teeth may be further protected with a permanent onlay or a crown to restore its shape and functionality.
