What is a Root Canal?


Root canal is a dental treatment used to repair and save a badly decayed or infected tooth. The procedure is carried out to remove the nerve and pulp when they get infected or badly damaged. After removal of nerve and pulp, the tooth is cleansed and sealed.

Root canal is known to be a painful procedure. It may also include some extended procedures like tooth extraction, dental bridge, dental implant, and/or removable partial denture.

Why Root Canal is Needed?

Root canal becomes inevitable when your tooth decays or gets damaged badly due to trauma or any other reason. Tooth may decay due to the presence of bacteria that has the propensity to multiply and cause severe damage in just no time.

When the bacteria enter into your tooth, they attack your nerves and stop blood supply to it which ceases the antibacterial cells to transmit and fight against them.

How to Know You Need a Root Canal Therapy?

Root canal therapy is usually suggested by your dentist after teeth examination. However, there are signs that may indicate that you may need a root canal therapy as the suggested course of treatment.  These signs include;

  1. Severe toothache when chewing
  2. Sharp pain (or sensitivity) for a prolonged period
  3. Swelling in nearby gums
  4. Discoloration of the tooth
  5. Persistent pimple on the gums

How Root Canal is Done?

Root canal therapy may be performed by an endodontist or a general dentist. Your dentist may require you to visit twice or thrice to perform the treatment in phases.

Prior to treatment, X-rays are taken to check the severity of damage.

Firstly, the decay is removed and an opening is left to reach the pulp chamber. Infected pulp is then removed using specific dental instruments. This is done after injecting local anesthesia to control the pain.

Once the pulp is removed, the pulp chamber and root canals are flushed and cleaned. After cleansing, the tooth is usually left open for some days. Some medication may be put into your pulp chamber and root canal to clear it from infection. You may be prescribed to take antibiotics if the bacteria are spread beyond the tooth.

After your tooth is completely clear and dry, you dentist performs dental filling to fill the interior of the tooth. You may not need anesthesia for this procedure.

Finally, your tooth is protected from future damage and restored to its normal condition. This is done by placing a crown which could be made up of gold or porcelain, tinted to match the color of your teeth to give natural look.

Once your root canal treatment is done, your tooth can function normally. By taking care of it and maintaining good oral hygiene, you can protect your teeth from future decaying or damage. In the first few days, your tooth may be sensitive that can be treated using over-the-counter medicine. If the problem persists, be sure to talk to your dentist.
