Each tooth has these parts: the crown, cervix, root and pulp. The crown is the top of the tooth that you can see. The root is the part of the tooth that goes down into the gingiva and jawbone. The pulp is the center or “canal” of both the crown and root. The pulp is a living tissue which includes blood vessels and nerves. Root canal therapy is designed to correct disorders of the dental pulp.
What causes pulpal nerve damage?
-physical irritation brought on by aggressive tooth decay reaching down to the nerve or through deep fillings, which allows harmful bacteria to reach the nerve
-trauma: a blow to a tooth or the jaw can cause damage to sensitive nerve tissue within the tooth
Symptoms of the pulpal nerve damage:
-tooth pain while chewing
-over-sensitivity of the teeth with hot or cold drinks
Why is root canal procedure necessary?
Without treatment, the infection of the dental pulp will spread to the bone around the tooth, making it no longer able to hold the tooth in place. Untreated root canals might also affect your general health. After permanent root filling, usually a crown is fabricated to complete the rescue and restoration of the natural teeth.
