Root Canal Therapy
Root canal therapy refers to the treatment of the inner aspects
of a tooth, specificiallly the pulp tissue (the nerve and blood
supply for the tooth). An infection inside your tooth that
reaches the root and its nerves can be painful, and a root
canal is needed. Other causes for root canal therapy include
trauma, deep decay, or a cracked tooth. Sometimes there
may be no apparent cause, only that a tooth hurts.
Root canal therapy relieves the pain by removing the pulp of the
tooth and then refilling the space to keep the area clean.
Antibiotics are sometimes uses in addition to root canal therapy to
help treat the infection. After a root canal, the tooth
will likely require a crown, because the process causes the tooth to
become more brittle.
