Root Canal Treatment

Oral health

What is a root canal treatment and why is it needed?

Root canal treatment (also known as endodontic therapy, endodontic treatment, or root canal therapy) is concerned with the dental pulp as well as the tooth and its surrounding tissue. The complexity of the mouth, the teeth and the entire structure makes endodontics very complicated; it requires skill and expertise acquired through many years of study and training. Anything from root canal treatments (a type of treatment used to save decayed or badly damaged teeth) to injuries from trauma to the teeth falls within the specialized area of endodontics. An endontist uses various highly advanced tools, techniques and technologies to aid them in their professions and give them a good view inside mouth. Their skill also lies in providing quick treatment with as least discomfort as possible. Based Malta’s major commercial area, Camilleri clinic can save your tooth and keep you smiling.

This is a type of treatment to save and repair a tooth that has been badly infected or decayed instead of removing the tooth. If not treated, the tissue surrounding the tooth will become infected and abscesses may form or worsen. The root canal is actually the natural cavity within the centre of the tooth were the nerve/pulp is situated.

Will the root canal treatment be painful?

A local anaesthetic is used and it should feel no different to having an ordinary filling done. After the first visit no more anaesthesia is required as the pulp would have been previously removed. For the first few days following the completion of a root canal treatment, the tooth may feel slightly sensitive due to natural tissue inflammation, especially if there was pain or infection before the procedure was carried out. After a few days this slight sensitivity will then resolve completely.

What will my tooth look like after treatment?


In the past, a root filled tooth would often darken after treatment. However, with modern techniques this does not usually happen. If there is any discolouration, there are several treatments available to restore the natural appearance.

What about aftercare and how can a root canal treatment be prevented?

Root-treated teeth should be treated just the same as any other tooth. See your dentist for regular check-ups. Since some of the reasons why the nerve of a tooth and its pulp become inflamed/infected are due to deep decay, repeated dental procedures on early carious lesions, following good oral hygiene practices (brushing twice a day with a fluoride toothpaste, flossing at least once a day, and scheduling regular visits at the dentist) may reduce the need for a root canal treatment. Cut down on sugary snacks, and keep them only to mealtimes, if possible. Trauma resulting from sports-related injuries can be reduced by wearing a mouth guard.


What Are the Signs That a Root Canal Is Needed?

Sometimes some or none of the following symptoms are present; still, signs you may need a root canal include:

  • A severe toothache upon chewing or application of pressure and excruciating pain at night
  • Prolonged sensitivity/pain to hot or cold temperatures even after the stimulus is removed
  • Discolouration/ darkening  of the tooth
  • Swelling and tenderness in the nearby gums
  • A persistent or a recurring pimple on the gums

What causes inflammation or infection of the pulp?

Several factors can lead to infection or inflammation of the pulp. These include;

  • Deeply decayed teeth leading to bacterial infection
  • Large long-standing leaking restorations or thermal insult from repeated dental procedures on the same tooth
  • Trauma and fractures to the teeth

What does the procedure involve?

The aim of the treatment is to remove all the infection present inside the root canal. A root canal treatment is a skilled and time-consuming procedure. The procedure will usually involve two or more visits to your dentist depending on the infection present in your tooth. At the first appointment, the infected pulp is removed.  In between appointments a dressing and temporary filling are placed in the tooth. The tooth is checked at a later visit and when all the infection has cleared and the root canal is shaped and cleaned well, the tooth is permanently filled or a crown is placed.
