Remove the Pain and Stop Dental Infection.

A root canal allows the healing of a tooth on which the decay has reached the nerve. Once the infection reaches the pulp , the only way to remove the pain is the root canal of the tooth or the root canal.

Causes of a Root Canal.

Deep Decay

Eruption of both layers of the tooth irritates the nerve center of the tooth and causes an inflammatory reaction responsible for the acute pain experienced.


A deep fracture can expose the nerve of the tooth and induce an inflammatory reaction responsible for the acute pain experienced.


In the case of dental infection, if the tooth does not respond to antibiotics, root canal is necessary to save the tooth and remove tooth pain.
