When is a root canal really necessary?
Tooth extraction can be avoided in many cases and root canal treatment can extend the life of your tooth by many years.
Root canal treatment can be an excellent solution:
in case of sharp, throbbing, unrelenting toothache
in case of swelling of the face, which may be a sign of inflammation around the root apex
in the case of extensive, deep tooth decay, if it affects the tooth pulp
or if a previously treated tooth causes symptoms.
