Root canal treatment is a crucial procedure designed to save a tooth that is severely decayed or infected. It involves removing the damaged or infected pulp (the soft tissue inside the tooth containing nerves and blood vessels), cleaning and disinfecting the inner canals, and then filling and sealing the space. Contrary to common myths, modern root canal therapy is typically comfortable and highly effective in relieving tooth pain and preventing tooth loss. After the procedure, the tooth is often restored with a crown to protect it and restore its full function.
