“Root Canal” is not a word that is greeted well by anyone. The best way to avoid a root canal is by learning more about it so you are aware of how to treat it with the least discomfort and prevent the occurrence of future ones. 

What is a Root Canal?

A root canal is the treatment of repairing damaged canals inside a tooth’s root (pulp). It involves cleaning up the affected area, removing damaged parts, disinfecting it, filling and sealing it by a dental specialist. The procedure involves a few steps:

  • First, you need an x-ray to examine the area and identify the location of decay.
  • Next comes local anesthesia to numb the area and prevent pain.
  • Then comes opening up the area to be treated to remove the decayed pulp in a process called pulpectomy.
  • The last is filling the opened area and sealing it with cement.

Signs of a Root Canal

Constant Pain

Persistent pain and sensitivity are some of the key indicators of a root canal. If they prevent you from eating, drinking, talking or sleeping, contact a dentist at once to check for an infection in the nerves or blood vessels. It can start as a dull pain and aggravate into sharp, intense, persistent pain. Antibiotics can lessen the pain, but if it persists, a root canal may be the only option to eliminate the infection from the roots. 

Chipped Tooth

Often a root canal can develop from a chipped or cracked tooth caused from an injury, eating hard foods or previous dental procedures that have acted up from faulty treatments. Chipped tooth exposes the nerves under the surface making you vulnerable to infections that can enter the bloodstream and spread. Your gums may be swollen and painful too. If you have a chipped or cracked tooth or inflamed gums, consult your dentist at once to prevent the infection from worsening. 

Decay and Discolouration

Discolouration and decay can occur from poor dental hygiene, food that stains teeth, enamel wear or nerve damage under the tooth. Deep decay is hard to get rid of. If it spreads to the tooth below the surface, the damaged roots will have to be removed if the blood vessels and nerves are affected. You will need a crown to protect the weakened, treated tooth.

Oral hygiene is extremely important on a daily basis to protect your teeth. If you suspect deep decay or root canal or feel any persistent discomfort at all, don’t panic. Just schedule an appointment with a trusted dentist.
