Root Canal Treatment

A root canal treatment is an endodontic procedure used to repair and save a severely infected or badly decayed tooth. It helps to relieve pain and make the tooth healthy.

During a root canal procedure, the infected pulp tissues are removed. After which, the inside of a tooth is disinfected and cleaned before it gets sealed with a filling.

With treatment, the tooth can recover and revert to its normal functions. Otherwise, the tooth may have to be extracted.

The root canal is the space within the roots of a tooth that contains dental pulp.

The pulp is a soft tissue that extends from the crown to the tip of the roots and contains nerves and blood vessels.

As a result of tooth decay or injury, the pulp can become inflamed. If left untreated, the infection can spread to the tissue around the tooth and abscesses may form.

To save the natural tooth, root canal treatment removes the nerves and pulp within the tooth and cleans it before sealing it.

Without the pulp, the tooth can still remain healthy by receiving nourishment from the surrounding tissues. The removal of the nerves will only affect the ability of the tooth to detect hot or cold temperatures.

Root canal treatment may be indicated for a fractured tooth due to injury or a badly decayed tooth.

As a general guideline, a root canal may be required when you display any of the following symptoms:

  • Serious pain while biting or chewing
  • Deep decay in tooth
  • Prolonged sensitivity to hot or cold food and liquids that lingers after the stimuli has been removed
  • Tender or swollen gums near the problem tooth
  • Darkening of gums
  • Recurring pimple-like bumps near the infected tooth
  • Avoid extraction

    Root canal treatment prevents your natural teeth from being extracted, giving you a more confident and natural smile.

  • Eliminates pain

    When the dental pulp is inflamed or infected, this can cause pain. Root canal treatment, therefore, helps to resolve this sensation.

  • Reduces chances of infection

    By removing any abscesses, root canal treatment helps to reduce the chances of oral infections.

  • Improve the appearance of teeth

    After the root canal treatment procedure, a crown will be placed over your natural tooth. This restores the appearance of your tooth, giving you a confident smile.

  • Shorter overall treatment time

    Root canal treatment may offer a shorter treatment time overall due to fewer follow-up appointments. This is in comparison to extraction, where dental bridges, implants or dentures may be used to restore the missing tooth.

  • Administration of anaesthetic

    During your 1st visit:

    Anaesthetic may be injected to numb the area surrounding the affected tooth. This helps to prevent you from feeling any pain during the procedure.

  • Removal of pulp

    Afterwards, a small opening will be made on the top of your tooth to expose the infected pulp. The dentist will proceed to clear the diseased pulp from within the tooth using dental files.

    During which, special care is taken to clean the canals within your tooth.

  • Filling of tooth

    Once the infected materials have been removed and the tooth has been properly cleaned, it will be filled.

    The opening made will be sealed with a temporary filling until you are ready for the dental crown fabrication.

  • Crown fabrication

    The root canal treated tooth is trimmed and prepared for digital scanning or impression taking. The crown will then be fabricated in the lab.

  • Placing of crown

    During your 2nd visit:

    The dentist will place a permanent crown on top of your tooth.

    Depending on the severity of your condition, a small supporting post may be placed in your tooth to enhance the stability of the crown.

Contrary to what you read on the internet, the goal of a root canal treatment is not to cause you pain but to help you relieve it.

Most people can expect to feel a mild pain that should subside in a few days following the treatment. Extended periods of pain could indicate that something is wrong. Contact your dentist as soon as possible if the pain persists.

Root canal treatment is a common procedure that can help to save your natural tooth. As it is a delicate procedure, there are some potential side effects, although uncommon:

  • Inflammation of the sinus cavity (subsides within a few weeks)
  • Recurrence of infection due to erosion of the tooth’s seal or an untreated root canal
  • Numbness around the affected area
  • Loss of a tooth caused by weak enamel or severe tooth damage
  • Abscesses forming at the root caused by leftover infected pulp or ineffective antibiotics

The chances of these situations occurring is generally low. The success of the procedure is dependent on each individual’s condition and medical history and the dentist’s experience.

At times, the decay or fracture may be serious enough that it affects the integrity of the tooth and root structure. Root canal treatment will not be suitable in such cases as there is a possibility of failing.

A more suitable alternative would be dental extraction, where your tooth is extracted and replaced with a denture, bridge or implant. This helps to restore chewing, prevent shifting of teeth and reduce risks of gum diseases.

However, root canal treatment is the preferred treatment (if possible) as it fixes your natural tooth.

For a speedy recovery post-root canal treatment, you should take the following measures:

  • Get a dental crown placed

A root canal treated tooth loses it’s tooth structure and makes it more prone to fracture. For that reason, a crown is required to provide proper protection against the strong forces of chewing and biting.

  • Reduce the stress on tooth

Root-canal treated teeth are more brittle and susceptible to fractures. As such, you should avoid chewing or biting on the treated tooth to minimise the stress placed on it.

  • Maintain good dental hygiene

After treatment, it is imperative that you stick to an oral care routine to maintain your crown and avoid future tooth infections. This consists of brushing your teeth thoroughly and gently, flossing, and attending regular checkups and cleaning sessions.

You are advised to have plenty of rest after the treatment, but you should be able to get back to work the next day. Consult your dentist for more detailed aftercare instructions.

About 90% of root canals last up to 8 – 10 years with proper care.
