Root Canal

 

Your dentist may have suggested to you that Root Canal Therapy ( otherwise known as Endodontics ) was needed for a particular tooth. They may have briefly discussed some of the facts concerning the procedures involved in root canal therapy but perhaps you would like some more information.

Years ago, a badly infected tooth, or one that just had significant decay, was doomed to be extracted. Today the majority of these teeth can be salvaged through a procedures utilized by both the General Dentist and the root canal specialist, the Endodontist.

Extraction is truly our last resort!
Some indications of the need for root canal treatment may be:

  • Spontaneous pain or throbbing while biting.

  • Sensitivity to hot and cold foods.

  • Severe decay or an injury that creates an abcess (infection) in the bone.

Root canal treatment consists of:

The removal of the infected or irritated nerve tissue (Fig.2) that lies within the root of the tooth. It is this infected pulp tissue that causes an eventual abscess.

  1. 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. ( Fig. 3 )

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

  3. At the same visit, the canal where the nerve is located will be reshaped and prepared to accept a special root canal filling material. This filling procedure will probably not occur until your next visit. 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. (Fig. 4)

  4. 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.( Fig. 5)

 

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. (Fig. 6)

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

Another “ Old Wive’s Tale “ is that by removing the nerve the tooth becomes “ dead “. This is not true. The tooth is very much alive and functioning because it receives a source of blood supply and nerve supply from the surrounding tissues that hold it in place in your jaw bone. The tooth will have no sense of feeling to hot, cold or sweets but will be responsive to biting pressures etc. With the proper restoration the tooth should last as long as your other teeth and can even be used as an anchor tooth for a partial denture or cemented bridge. 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 first or second 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. In either case, be sure to call your dental office if either of these problems should arise.

 

POSTOPERATIVE INSTRUCTIONS

  1. Postoperative discomfort is sometimes experienced after a treatment visit. This is due to irritation of the bone surrounding the tooth and may range from a mild discomfort in the area to an occasional episode of considerable pain. This discomfort will usually maximize in approximately 48-72 hours and then subside. Please avoid chewing on the treated tooth for a few days.

  2. If a throbbing sensation occurs please keep your head elevated as much as possible and place extra pillows under your head when lying down. Avoid as much as possible any strenuous activity as well.

  3. If your tooth has been left open to aid in drainage of an infection, please place cotton in your tooth as directed. Do not leave the cotton in the tooth between meals.

  4. If swelling of the gum is present or should appear after a treatment visit, please rinse the area every 1-2 hours with a solution of warm salt water prepared by adding a teaspoon of salt to an 8 oz. Glass of warm water.

  5. If swelling of the face is present or should appear, apply an ice pack to the area for 5 minutes every ˝ hour.

  6. If antibiotic medication has been prescribed please take it as indicated until you have finished ALL of the medication. If you encounter any difficulty in breathing or a skin rash, or gastric disturbance should occur, please discontinue the medication and call the office.

 

  • If medication for pain has been prescribed , please take it as indicated. It is important to bear in mind that narcotic medications such as Codeine, Vicodin, Percodan and Demerol may make you drowsy. Therefore, caution should be exercised in operating any potentially dangerous machinery or an automobile.

 

If any additional questions should arise after your visit, please do not hesitate to call your dentist.
