Root Canal Therapy

 What Is Root Canal Therapy?

Primarily it is a means of saving a tooth by the removal of the pulp that is found inside every tooth.  Pulp is the term for all the tissues inside the canal, i.e. nerves, arteries and veins.  After the pulp has been removed the tooth can no longer react to its environment and no longer trouble you.  The huge advantage of Root Canal Therapy is that it gives the tooth a second life - the alternative is an extraction

Root Canal Therapy includes the procedure of filling up the now empty canals that remain after removal of the pulp with special sealants and fillers.  It is a tricky procedure and sometimes may take numerous appointments to complete.

 

 Why Should A Tooth Root Nerve Be Removed?


Tooth fracture or dental decay has exposed the nerve itself

The nerve is hypersensitive due to the exposed root surfaces or a prior dental procedure

The nerve has died (a dead nerve will result in the formation of an abscess if it is not removed.) Any bacteria that accumulate in the close pulp chamber or root system will eventually destroy tissues and lead to the formation of liquid (pus). The pus, together with rising pressure inside this close chamber can lead to intense pain and swelling, that typically represent a tooth abscess. Very often NO PAIN is present during the development of a chronic abscess.




 Root Canal Therapy: The Procedure

Root Canal Therapy is often done in 2 or more appointments. Curved roots can sometimes complicate the procedure dramatically and makes Root Canal Therapy a very lengthy process.


First Appointment:

After very good anesthesia, the tooth is opened up and the inside pulp chamber is cleaned out.

From this chamber towards the root tips, 1 to 3 canals are found, that lead to the root tip or apex.

Final Appointment:

After aneastesia the temporary filling is removed and further cleaning and  shaping of the canals take place.

This could be very time consuming, because each canal (sometimes there are 4) needs to be located and cleaned right down to the root.

 After The Nerve Has Been Removed


 

Discoloration is likely to occur later, but bleaching and crowning are good options to restore the colour to its original state. In the long run the tooth becomes more susceptible to fracture and it is advisable to strengthen the tooth with some form of restoration, usually a crown.

 

 Can I Expect Any Pain Or Discomfort Afterwards?

Following Root Canal Therapy the tooth sometimes feels traumatized and tender.  It can also be painful for a few days.  This pain does not originate from inside the tooth, but is itself a response from your body's immune system.  Inflammation takes place in the tissue surrounding the root and causes pain.  Another factor is that if there was an infection, like an abscess, the tooth is more likely to pain afterwards, because of a stronger reaction from your body's immune system.

 

 Care For Root Canal Therapy

AFTERThe FIRST APPOINTMENT When The Canals Are Still Open And Unfilled

Expect some pain that can last for about 72-hours.  It can be controlled with anti-inflammatory medication.

Make sure your final filling / crown is not too high in the bite, because this can cause unnecessary discomfort.  Contact your dentist to ease the restoration if necessary.
