Premolar Root Canal – Dental Treatment

Introduction –Premolar Root Canal

A root canal is a treatment in dentistry for repairing and saving a tooth which is badly decayed or is infected. During this procedure, the nerve and pulp of the tooth are removed followed by cleaning and sealing the interior of the tooth. If root canal is not done in time, the oral tissues get infected and may progress to an abscess.

Root canal is literally the natural cavity within the center of the any tooth. This cavity contains the nerve supplying the particular tooth. It also contains a soft area called as the pulp or pulp chamber. The nerve of the tooth only provides sensations like hot and cold. It is not important for the health or function of the tooth. So, the removal of this nerve does not affect the normal functioning of the tooth.

A root canal can be performed in single or multiple visits. Make sure from the dentist beforehand about the number of appointments necessary to complete the procedure.
After the nerve tissue or the pulp is damaged, various bacteria begin to grow within the chamber. This damage may be caused by decay, various dental procedures, large fillings, a crack or chip in the tooth, or injury to the face. An infection or abscess forms in such tooth due to the bacteria. An abscess or a pus filled pocket is formed when the infection spreads to the ends of the roots of the tooth. Other complications also can arise due to these infections, like swelling of the face, head or neck, bone loss in the root or formation of fistula which can drain the pus to cheeks or skin.

All these problems are more common in premolar tooth as many times it is not cleaned properly due to its location or inadequate oral hygiene. Also, these teeth are the frequent ones to undergo the dental procedures.

Signs and symptoms:

  1. Pain in the tooth on chewing or pressure
  2. Abnormal sensitivity to extremes of temperatures
  3. Swelling of gums
  4. A recurring pimple on gums

Before the Procedure:

A root canal can be performed in single or multiple visits. Make sure from the dentist beforehand about the number of appointments necessary to complete the procedure. If the patient has infection or abscess in the tooth, the dentist starts a course of antibiotics before the root canal. A baseline X-ray is taken to examine the shape of the root canals and also for any signs of bone infection. After this,

  1. A dentist or endodontist first numbs the area around the bad tooth with the help of anesthetic medicine injected by a small needle. A slight prick is felt when the needle is inserted. A rubber dam is placed around the tooth.
  2. The covering or top part of the tooth is removed by a small drill, thus exposing the pulp chamber. This pulp contains nerves, blood vessels, and connective tissue. The pulp extends from root of the tooth to the jaw bone.
  3. The diseased pulp is removed by using a special instruments called as files. The small canals inside the tooth are cleaned. The area can be medicated to prevent further infection.
  4. Then, this area is sealed by a temporary material. A permanent crown may be placed over the filled tooth.
  5. A course of antibiotics is given to treat and prevent infection. Pain relievers are also prescribed for a limited period.

After the procedure:

At the next visit, the dentist makes sure that the infection is gone. A dental x-ray may be repeated. Regular visits to the dentist are necessary at least twice a year.


New infections can occur even after a successful root canal. The reasons may be:

  1. A prolonged procedure stretching for more than anticipated time.
  2. Crack or chip in the root
  3. Defective restoration
  4. A breakdown of the inner material used for sealing.

Generally, with antibiotic treatment and some adjustments by the dentist, these problems can be taken care of. But sometimes a surgery is necessary.
