What is root canal treatment?

A root canal treatment refers to the cleaning of the canals inside the root of your tooth. These canals contain nerves, blood vessels and connective tissue called pulp. When a tooth is broken or develops a deep cavity, bacteria can enter the pulp causing infection that needs to be treated.

Possible Causes: 

When a tooth cavity has been untreated for a long time, bacteria can enter the soft core of the tooth (called the pulp) through this cavity, causing serious infection. A root canal treatment is required to drain the diseased pulp, cure the infection and seal the damaged tooth. Other root canal causes are worn tooth enamel or fillings, gum infection or exposed roots.

Risk Factors: 

You could be at a higher risk of serious teeth infections due to the following factors:

  • Poor oral hygiene
  • Delay in treating infections and cavities

Signs & Symptoms: 

Severe toothache, especially in a cavity could be an indication that you need a root canal treatment. Other symptoms could be facial swelling, a crack in your tooth, swollen gums and sensitivity to hot or cold temperatures.


At the outset, the dentist at Medcare will take an X-ray of the painful or infected tooth. The result of the X-ray will help the specialist observe the shape of the root canals and determine if there is any infection in the surrounding bone. The treatment will be recommended with an intention to save the tooth as far as possible.

Treatment Options: 

At Medcare, the root canal treatment steps may involve:

  • First the decay is removed and in order to reach the pulp chamber, an opening is made through the crown of the tooth.
  • The infected pulp is removed and the whole area, including the root canals are flushed and disinfected.
  • A dental filling is placed to protect the root canal from saliva.
  • Finally a crown or an artificial tooth made from gold, porcelain or metal completes the restoration process.
FAQs:الأسئلة الشائعة:
  • Why am I being advised to get a root canal? Why will a normal filling not achieve the same result?

    A: Your dentist will advise you to have a root canal treatment if your tooth is badly infected and decayed. This treatment makes it possible to save the tooth. The pulp of your tooth, composed of nerves and blood vessels, has got infected or damaged. During the root canal treatment, this pulp will be removed, and the inside of the tooth will be cleaned and sealed. This cannot be done during a regular filling procedure.

  • Will I need a crown on my tooth after the root canal treatment?

    A: It is very likely that your dentist will advise your tooth to be crowned after a root canal, and yes, you should definitely heed this advice. The crown helps to strengthen the tooth, which gets weakened because all the pulp has been removed. The crown enables the treated tooth to last for a long time. 

  • What are the success rates of root canals? How long can I expect that tooth to last?

    A: Root canal treatments are highly successful. Research shows that the success rate is over 95%. Many teeth that have been treated with this procedure last the lifetime of the individual. So you can expect good and long lasting results from a root canal treatment.

  • My dentist has told me that a root canal is necessary, but I’ve heard this is very painful, so I’m doing my best to avoid it.

    A: It’s a myth that a root canal is very painful, the current methods and techniques make this procedure virtually painless. Please remember that avoiding the root canal can cause complications such as abscesses, and in fact, lead to excruciating pain, much worse than root canal treatment pain. So if your dentist has advised a root canal treatment, meet the dental specialist and start on this procedure as soon as possible.
