What is a Root Canal Treatment?

A root canal treatment is a dental procedure that removes infected pulp or the soft centre of the tooth in order to avoid a tooth extraction. In most cases a local anaesthetic is administered to the patient prior to the procedure being done.

Why would a root canal treatment need to be carried out?

If the pulp or soft inner part of a tooth is injured and becomes infected or inflamed then a root canal is performed where the infected pulp is removed to preserve the structure of the infected tooth. The dental pulp is made up of nerves, blood vessels and connective tissue that help the tooth grow and stay healthy.

The most common reasons for the pulp to be damaged include:

  • A chip or crack in the tooth
  • Deep decay caused by an untreated cavity
  • Multiple dental procedures on the same tooth
  • An injury to the mouth, even if the tooth does not crack can cause damage to the pulp

What type of dentist carries out this treatment?

While it is possible for general dentists to carry out a root canal, owing to its complexities it is generally done by a specialist in root canal treatment, known as an endodontist. Referred to as root canal dentists, endodontists undergo additional training in dental pulp disorders and so have a higher level of expertise when it comes to endodontic treatments.

Root Canal Treatment Procedure

There are four main elements to a root canal treatment and in order to complete it entirely you may need more than one visit, depending on the difficulty of the procedure. The basic process is listed here but may vary slightly depending on what your dentist or endodontist recommends for you. A local anaesthesia will be administered before the treatment is started.

Removing the active decay and infection – The first step of the canal treatment is to remove the infected nerve tissue, old fillings, the tooth decay and debris to leave a cleaner area
Shaping the canals – Once cleaned, the canals within the root of the tooth, need to shaped into smooth hollow tunnels in order to be filled well. There cannot be any irregularities or residual bacteria so this step that may have to be repeated several times. It sometimes takes a few weeks for the special disinfectants and medicines to take effect against stubborn bacteria within the tooth.
Filling the canals – This process is to stop bacteria from re-infecting the tooth it is permanently filled and sealed with a long-lasting barrier material.
Creating a functional tooth – To help the tooth become functional again, a seal such as a crown is put on the tooth, to keep bacteria from re-entering the oral cavity. As the tooth may have lost considerable tooth structure, further protection might be necessary in the form of porcelain or gold alloy crowns.

How long does the treatment process take?

Some rare simple root canal procedures can be sorted in one appointment lasting about 30 minutes to over an hour. However, generally it takes two appoints with more severe or complicated cases needing a longer period of time with a third appointment. If additional appointments are needed your tooth will have a temporary filling during the periods between the appointments to ensure it stays as clean as possible.

Am I suitable for a root canal treatment?

If you are experiencing pain in your tooth and swelling and heat in your gums near the tooth then you should check with a dentist as these are signs of a damaged pulp. After an examination and an x-ray to confirm the diagnosis you will be recommended for a root canal.

How painful are root canals?

Root canals are not painful because dentists now use a local anaesthetic before starting the root canal procedure to numb the tooth and surrounding areas. You may feel slight pain and discomfort once the procedure is completed but you will be prescribed mild painkillers by your endodontist.

How long does it take to recover from a root canal treatment?

It generally only takes a few days to recover, with soreness or irritation lasting for about 24 to 48 hours. To manage the pain your dentist will prescribe over-the-counter pain medication which will see you through those few days. If pain or discomfort persists after a week then do get in touch with your endodontist.

Are the fillings permanent or temporary?

The root canal is sealed with a permanent filling to prevent bacteria or fluid from entering the tooth. A temporary filling is used between the treatments which is replaced with a permanent one once the root canal heals.

Do you need a crown after a root canal?

Most often if the tooth can be restored with the dental filing only a crown is not necessary. However, if it is a front tooth and it has discoloured by decay then for cosmetic purposed a crown should be fitted.

Will I require follow up treatments after the procedure?

With proper care your root canal will be able to last a lifetime. While you may not require follow up treatments, if you have been asked to come in for a check-up, make sure you do so to ensure that everything is in order. If you start to feel pain at some later date, then do visit your endodontist.

Aftercare - How to take care of the treated area

Right after the procedure your mouth will still feel numb owing to the anaesthetic and as a result eating will be a little difficult. Once the numbness is gone and you eat, avoid chewing or biting down on the treated tooth for a day or two to avoid damaging it. Avoid hard foods for a while just to give your tooth time to heal completely.
