Root Canal Treatment
Root canal therapy restores and saves an average
of 17 million teeth each year. Keep your tooth
and stop the pain sounds better than a tooth
extraction, right? What Exactly Is a Root
Canal? A root canal is a dental procedure that is
used to remove diseased pulp tissue from the
interior of a tooth. The narrow channels beneath
the pulp chamber in the inner part of the tooth
are hollowed out and cleaned, and the roots are
filed with flexible nickel titanium files.

A tooth is made up of three main components a
hard protective shell referred to as enamel, a
softer and sensitive middle layer referred to as
dentin and a soft tissue inner layer referred to
as dental pulp. Dental pulp is composed of nerve
tissue, lymph tissue and blood vessels, and is
considered to be the vital part of a tooth. If
dental pulp is sufficiently traumatized whether
by exposure to oral bacteria via deep dental
caries, a fracture in the tooth that enters the
pulp or a forceful blow to the face the tooth
begins to die and root canal therapy is often
required in order to prevent or eliminate
infection and prevent tooth loss. A root canal
procedure involves tooth disinfection and the
removal of all debris (nerve tissue, lymph
tissue, blood tissue, bacteria and infection)
from the coronal pulp chamber and its associated
canals. Once an affected tooths canals are
sufficiently cleansed and shaped, they are filled
with materials designed to prevent pain and
infection from recurring.

Root Canal Signs Certain signs may indicate that
you have a diseased tooth or infected nerve and
therefore may need a root canal. These signs
include

• Minimal to severe pain.
• Tooth discoloration.
• Swelling and irritation in the surrounding gum
  tissue.
• Signs of infection visible on a radiograph.
• Dentists typically recommend a root canal in such
  situations to save the affected tooth and
  preserve its functionality.

Why Are the Associated Toothaches So Painful?

• Nerve fibers, blood, and lymph tissues are housed
  in the root canals. Located inside each tooth is
  a pulp chamber that funnels into those root
  canals. A tooth can become inflamed or infected
  for several reasons, including severe tooth decay
  or a crack or chip in the tooth. Failing
  restorations such as dental fillings and dental
  crowns can foster bacterial leakage into the
  dental pulp. Once infected, the dental pulp
  begins to die and the bodys inflammatory
  responses set it. The combination of infection
  and inflammation can cause significant pain. The
  end result is a toothache.In cases where tooth
  extraction is the only solution, the missing
  tooth may be replaced with a dental implant or
  dental bridge to maintain functionality. By
  replacing the missing tooth, a proper bite is
  maintained and the surrounding teeth are
  prevented from shifting. Because a severe
  infection can be very dangerous, it is important
  to receive a professional evaluation by a dentist
  who can look deeper into the cause of a
  toothache. If an infection spreads beyond the jaw
  to the head and neck, then more extensive medical
  treatment, including hospitalization, may be
  required.
