The removal of the infected or irritated nerve tissue that lies within the root of the tooth. It is this infected pulp tissue that causes an eventual abscess.


The first step in a root canal is to obtain access to the nerve. This is accomplished by establishing a small access opening in the top of the tooth. It will be done under a local anesthetic.

The length of the root canal is determined and the infected pulp is removed.

At the same visit, the canal where the nerve is located will be reshaped and prepared to accept a special root canal filling material. The number of visits necessary to complete your root canal will depend upon several factors including the number of nerves in the tooth, the infected state of the nerve, and the complexity of the procedure.


The final step in your root canal will be the sealing of the root canal with a sterile, plastic material called gutta percha. This is done in order to prevent possible future infection.

If treated early, root canal therapy need not be uncomfortable. With the use of local anesthetics, the entire procedure can be totally painless.

The success rates for Root Canal Therapy have been reported to be as high as 95%

Sometimes when there has been long standing infection or abscess, there may be some soreness associated with the root canal visit. If this should turn out to be true, you will be given specific instructions to follow to minimize the discomfort. When an infection is present, it may be necessary to take an antibiotic. If pain should be present, analgesics may need to be prescribed.

The tooth will then possibly need a post and core and a crown in order to re-establish normal form and function. This decision will be based upon several additional factors.

  • Severe tooth pain, typically increases with the intake of hot liquids.
  • Pain worsens when you lie down and reduces when you sit up.
  • Pain stays for a long time after consuming cold things.
  • Swelling around the tooth.
  • Constant tooth pain
  • Pain when chewing.
  • Tooth pain referred to head and ears as well.
  • Tooth sensitivity on consuming sweets.

If you have any of the above stated symptoms, it would be advisable that you visit us, since dentist is the best person to judge whether you have a root canal disease or not, as some of these symptoms may be due to other problems as well.

Following Illustrations will explain you how the procedure is carried out.

Root ZX II Apex Locator Advanced Root Canal Instruments / Materials used in our clinics:– to determine the length of the root canal electronically. This instrument is considered to be the best in the world and has been the best selling apex locator in the world for several years running.

PROTAPER HandFiles, PROTAPER Paper Points & Gutta Percha Points

rt2The ‘Progressively Tapered’ – PRO-TAPER root canal files are made out of Nickel -Titanium for greater flexibility to reach into curved root canals and shape them in accordance with the latest crown-down technique of root canal treatment.

rt3Complimenting the Pro-taper Files are the Pro-taper paper points and gutta percha points which have been designed to match the shape of canals prepared with Pro-taper finishing flies, hence provide optimal coronal and apical fit and seal of root canal filling.

C+ Files

rt4These advanced files also from Dentsply, USA feature a variable taper design, have reduced flexion with greater buckling resistance and therefore have easier access to the root canal tip, especially during initial canal catheterization. They are considered the ideal choice for initial canal negotiation especially  in highly calcified canals, for re-treatment procedures and even for working length measurements.

Glyde Root Canal Conditioner & Lubricant

rt5Contains EDTA and Carbamide Peroxide in gel form. It reduces risk of instrument separation within canal by acting as a lubricant. It also removes the smear layer from canal walls and facilitates in optimal cleaning and sealing. It produces bubbling action in contact with Hypo-chloride (root canal irrigant) and helps remove debris from within the canals.

Sodium Hypo-Chloride Root Canal Irrigant

This is the main disinfectant in endodontic treatment and dissolves the necrotic pulpal tissue within the root canal preparing it for a sealed filling.

2% Chlorhexidine Root Canal Irrigant

2% Chlorhexidine solution when used for root canal irrigation along-with conventional root canal irrigation methods increases the success rate of the root canal treatment. 2% Chlorhexidine has been demonstrated to achieve higher levels of root canal disinfection when compared with conventional techniques alone.

Fiber Posts:

rt6These are used to restore badly broken down teeth which may otherwise have to be extracted. These have flexibility similar to that of natural tooth.

Root canal is usually painful.

“When people are told that they will require a root canal treatment, they usually associate the treatment with pain.”However, the pain they feel is caused by the infection in the tooth, not the root canal treatment. A root canal is done to eliminate that pain, and it is rather seldom that the procedure itself creates any symptoms.

“A local anesthetic, provided before beginning treatment, numbs the tooth and the surrounding area and ensures that the root canal procedure itself is painless,”

The tooth’s nerves are removed, so I won’t feel any pain.

“Many people believe that once they have had root canal treatment that they will no longer feel pain in the treated tooth. This, however, is incorrect. “While a person who has had a root canal procedure will no longer be sensitive to hot or cold food or beverages, he or she may still experience some discomfort for a few days after receiving root canal treatment. The pain may be caused by inflammation of the tissues that surround the treated tooth. If this happens, we may prescribe an anti-inflammatory medication which will help to alleviate the pain.”

I’m not feeling any pain, so I don’t really need a root canal.

“Most teeth that need root canal therapy will have no pain. However, not having symptoms does not mean that the tooth is OK,” if the tooth’s pulp is damaged or infected, then root canal therapy will be necessary.

“Sometimes you will not know that you have an infection because you are not experiencing pain, but if you see something near the damaged tooth that looks like a pimple that comes and goes, you should see your dentist,” “The ‘pimple,’ called a sinus tract, is caused by pus from an infection draining through a tunnel of tissue to an opening on the surface. It is important to have the infection treated and to receive root canal therapy. If you don’t, nearby tissues may be damaged.”

A root canal means I’m having the roots of my tooth, or my whole tooth, removed.

“During root canal treatment, it is the inside of your tooth and not the outside of your tooth that is treated,” “During root canal therapy, the dentist removes the tooth’s pulp, located in the center of the tooth, and does not remove the roots of the tooth or the actual tooth. The whole point of receiving root canal therapy is to try to save a tooth, not to remove it.”

After I get the root canal, I won’t have to go back to the dentist for a while.

“Once you have received root canal therapy, you might be tempted not to return to the dentist for a while, but it is important that you make follow-up appointments to have a permanent retoration placed,”. “The root filling that is placed after the pulp has been removed seal the root from infection, but the crown of the tooth must be restored.

“If you do not have a crown made on the back teeth, you are at greater risk of fracturing the tooth when you bite down or chew,” “So you should make an appointment with your dentist when the root canal treatment is finished to have the permanent restoration placed.”

What is root canal treatment?

Root canal treatment is a dental procedure in which the infected or damaged pulp of a tooth is removed and the inside areas are filled and sealed. The pulp of the tooth is the soft tissue that contains nerves, blood vessels and connective tissue. It lies within the tooth and extends from the crown of the tooth to the tip of the root in the jawbone.

Why is the procedure required?

Root canal treatment saves teeth that would otherwise need to be extracted. The most common cause of pulp infection is a cracked tooth or a deep cavity. Both of these problems can let bacteria enter the pulp and causes an infection inside the tooth. If not treated, pus builds up at the root tip in the jawbone forming a “pus-pocket” called an abscess, which can cause damage to the bone around the teeth.

What preparation is required?

There is no preparation required for root canal treatment. Once the tooth is opened to drain, the dentist may prescribe an antibiotic. With the infection under control, local anaesthetic is more effective, so that the root canal treatment may be performed without discomfort.

What do you mean by nerve removal treatment of the tooth?

Once decay reaches the pulp of the tooth, it gets infected and the tooth has to undergo root canal treatment. It involves complete removal of the pulp, cleansing and filling with inert material. Since pulp contains few nerve endings which are removed, it is commonly referred to as nerve removal treatment.

Do root canal treated teeth fracture?

No, a tooth with minimal destruction that is well restored does not fracture in normal usage. However, a grossly destroyed tooth may fracture if it is not protected by a metal crown. 6.Can decay occur on root canal treated teeth? Root canal treated teeth are not immune to decay; hence, proper brushing and oral hygiene maintenance is necessary to keep decay away.

Can decay occur on root canal treated teeth?

Root canal treated teeth are not immune to decay; hence, proper brushing and oral hygiene maintenance is necessary to keep decay away

How is the procedure performed?
During the treatment, the infected pulp is removed, the pulp chamber and root canals are cleaned and sealed. The steps involved are:

  • An opening is made in the crown of the tooth.
  • The pulp chamber and root canals are cleaned.
  • Medications may be put in the pulp chamber and root canal to help get rid of bacteria and treat the infection.
  • A temporary filling is placed in the crown opening to protect the tooth between dental visits.
  • In the final step, the temporary filling is removed and a permanent filling of metal or porcelain crown is usually placed over the tooth.

Root canal treatment can sometimes be completed in one visit but often several visits are needed. Back teeth usually require more time for treatment because they have more canals, which are narrower and harder to reach. During the treatment, x-rays need to be taken at each stage to assess the length and position of each of the root canal.

Is it true that a root canal treated tooth does not have any sensation or pain?

As the nerve supply to the tooth is removed the tooth does not respond to heat, cold, etc, like other normal teeth but continues to function like other teeth in the mouth.

Can a tooth with an abscess or infection that has spread beyond the root be saved by R.C.T.?

Once the pulp gets infected and adequate treatment is not carried out there is a chance that the infection may spread to the underlying bone. In such cases the infection forms an abscess in the bone which is nothing but collection of pus. Such an abscessed tooth can be saved by antibiotic therapy followed by root canal treatment. However, these patients required to be followed up regularly by X rays and clinical check up until complete healing take place.

Is there an age limit for R.C.T.?

A tooth that is completely developed can be treated by routine root canal treatment. However in young children the roots of the teeth are still developing. In such children it may be required to first undertake treatment to develop the root or close its wide open end and then complete the root canal treatment.

Can root canal treatment be performed in milk teeth?

Yes it is done on primary teeth when the decay involves the pulp.

What are the alternatives to root canal treatment?

Extraction or removal is the only alternative. The extracted tooth will have to be replaced by a denture, bridge or implant. Otherwise, the neighboring teeth will move into the space, creating problems with eating and cleaning. These problems can cause gum disease and new cavities.
