Root canal therapy involves the removal of blood vessels and nerves from the dental pulp to devitalize the tooth. Once the pulp has been removed and the space is cleaned, it is filled with a natural rubber material to seal the space. Although the tooth is no longer alive, it can be saved by this treatment.

However, teeth that have undergone root canal treatment may still be prone to decay. What’s more, since they are no longer alive, they are more vulnerable to fracture. It is therefore advisable to protect the tooth with a crown to prolong its life. If properly cared for, a tooth treated in this way can last a lifetime.
