Root Canal Therapy

Root canal therapy (RCT) is the process of treating a deeply infected tooth by removing the infected matter, sanitizing the root canal, filling the area with an inert material, and resealing the tooth, thereby preserving the original tooth.

The procedure was first developed over 200 years ago. The advent of modern anesthetics made the procedure more practical. During the last 20 years, modern technology and new methods have vastly improved the treatment success and patient comfort levels.

At Precision Dental in Fortitude Valley, we are constantly being updated and we regularly attend specialised seminars to stay abreast of the newest technical procedures and methods in the science of root canal therapy.


Background on What Makes RCT Necessary

Teeth are composed of three basic parts:

  • The hard outer layer of enamel that forms the visible crown of the tooth
  • The dentine under the enamel that supports the crown of the tooth
  • The root canal: the hollow centre of the tooth which extends from the base of the roots to the centre of the tooth, and is filled with a soft, organic material, dental pulp, that contains blood vessels and nerves which supply nutrients to the tooth.

It is when the dental pulp becomes infected that RCT becomes necessary to save the original tooth. Preserving your natural teeth is always preferable to alternative tooth replacement options.

The dental pulp can become infected for various reasons:

  • Tooth decay that has penetrated to the root canal
  • Tooth fracturing due to injury or genetic weakness
  • Excessive dental treatment on a tooth
  • Periodontal disease
  • Failed dental crown
  • Anything that allows infectious bacteria to invade the exposed dental pulp

Symptoms That Indicate a Root Canal Therapy Might Be Needed

In a word: PAIN

The pain can be sharp, intermittent, constant, localized to one tooth, extending from the jaw back to the ear, throbbing, inflamed gums, sensitivity to hot or cold foods, but almost always impossible to ignore.

This pain is your signal to immediately contact your dentist. The longer you wait, the more the infection will progress and the more difficult it will be to treat. Putting off a dental examination can have serious consequences and might mean the difference between saving the tooth or losing it.

Root Canal Therapy Procedure

The concept of RCT is quite simple, however the procedure is somewhat complicated and requires a highly skilled dental professional. Dr Billy Choi at Precision Dental has been preforming RCTs for over 10 years and is uncompromising in his devotion to meticulous, high quality dental practices.

An RCT procedure will consist of the following steps:

  • Thorough examination to determine the exact cause of the problem and the best treatment to remedy the situation
  • Exposing the infected root canal and removal of the dental pulp, nerves and blood vessels
  • Cleaning the root canal chamber and preparation of the interior root canal wall surfaces
  • Filling the root canal areas with a sterile, inert material to replace the previously infected dental pulp and preserve the integrity of the tooth
  • Sealing the root canal by installing a dental crown or permanent filling (Rear teeth are almost always sealed with a dental crown. Front teeth may sometimes retain their natural crowns, though this is not always recommended.)

You can expect at least two dental visits for this procedure, and possibly more, depending on your particular situation.

Rest assured, the professionals at Precision Dental are on your side and want you to enjoy the highest oral health and long lasting, trouble free dental solutions.

Precision Dental offers the most modern, effective, pain-free dental services and will provide you with the most convenient and comfortable dental treatments possible.
