Endodontics (Root Canal Therapy)

Is a procedure that enables patients to keep their natural teeth that would otherwise need to be extracted.

Tooth Clean 
Once a diagnosis has been made, the patient is given local anaesthetic to numb the tooth, thus making treatment very comfortable. A latex sheath called a Rubber Dam is then placed to isolate the tooth being treated, and maintain a clean working field. The dentist then proceeds to access the canals by making an opening and removing all tooth decay. (*Image A)  

Completing Root Canal
Next the dentist uses a series of calibrated precision hand held instruments called files or reamers to clean and shape the canals. X-rays are then taken throughout the procedure to ensure that the intruments go to the end of the root and not beyond. After the canals are cleaned, shaped and sterilized, they are ready to be filled with a rubbery material called Gutta Percha.
The material is injected into the canals and seals off the end of the root preventing any leakage. (*Image B) A temporary filling is placed into the opening, made to access the canals, and the patient is instructed to have this replaced with a permanent filling or a crown by his/her regular dentist.
