Root canal treatment

A very common misconception is that root canal treatment is painful. This is not true, and as a result every patient who has had such treatment at Holly Dental Practice is pleasantly surprised following completion.

When the nerve inside a tooth is dying off as a result of decay or trauma, the patient may experience hot and cold sensitivity, a throbbing or pulsing sensation, and then pain on biting or pressure. This is a sign the nerve has become infected and the tooth has an abscess. The only way to avoid extraction of the tooth at this point is to remove the infected nerve, disinfect the inside of the tooth, and then fill the space left. This process is known as Root canal treatment (RCT), or Endodontics.

How is it done?

At Holly Dental Practice RCT is carried out over a minimum of two appointments and a rubber dam is used to isolate the tooth during the procedure to ensure the maximum success rates.

At the first appointment, the infected nerve is removed and any abscess which may be present is drained. The length of each root is then measured and verified with an x-ray. The inside of the tooth is then cleaned, disinfected and shaped, before a medicine is placed to help remove the rest of the infection. The temporary filling will then be added to protect the treatment until the second stage.

At the second appointment, the dressing and medicine are first removed, and the tooth is again disinfected before placing the permanent root filling. The root filling (a rubber or thermoplastic material) is then compressed into each canal to permanently seal them. A filling is then needed on top of the root filling to restore and seal the rest of the tooth, and a crown may be required to prevent future leakage, and most commonly, fractures.
