Root canal treatment

A pain that returns every night, more acute than the day before. A tooth that suddenly reacts to heat, cold, or even nothing at all. A diffuse sensation, like an inner tension that you can’t seem to forget. When an infection sets in deep inside the tooth, these little signals become familiar and quickly overwhelming!

We understand that root canal treatment doesn’t have the best reputation: it’s often thought of as long, painful, and complicated. However, it often offers immense relief. It ends the discomfort, prevents the infection from worsening, and avoids the need for tooth extraction.

You’re not alone in being apprehensive about root canal treatment. It’s a common reaction that we understand very well. That’s why we take the time to explain each step and guide you throughout the procedure, which, far from being daunting, is often the beginning of real relief.

Why have a root canal treatment?

Inside each tooth, there is a space containing tissue called the dental pulp. This tissue, which is also found in the canals that run through the roots, is sensitive. It is composed of nerves and blood vessels. When affected, whether by a deep cavity, an impact, or a crack, it can become inflamed or infected. Moreover, since the infection progresses in a confined space, the pain can quickly become very intense.

Root canal treatment removes this infected tissue, thoroughly cleans the canals, and then closes the tooth. The goal is simple: to stop the infection at the source, prevent it from spreading, and keep the tooth in place for as long as possible.

Contrary to popular belief, this is not an aggressive procedure, but rather a targeted treatment that provides long-term relief and protection.

How do you know if a tooth needs it?

Each situation is unique, but certain signs frequently recur:

  • Pain that occurs spontaneously and persists.
  • Marked sensitivity to hot or cold, without obvious contact.
  • Discomfort when chewing or applying pressure.
  • Localized swelling on the gum, sometimes accompanied by an abscess (accumulation of pus);
  • Or a tooth that appears to have changed color.

In other cases, no symptoms are noticeable until a routine exam or X-ray reveals that treatment is necessary.

How is a root canal performed?

Root canal treatment is sometimes perceived as a complex or painful procedure. It is a routine, precisely performed procedure that saves an infected tooth and avoids its extraction. Understanding the steps of treatment can help you approach this treatment with greater confidence and peace of mind.

Meticulous care to save the tooth

The treatment begins under local anesthesia to ensure painlessness. A rubber dam is placed around the tooth to keep it dry and protected from bacteria. The dentist then makes a small opening to reach the heart of the tooth, where the infected pulp is located.

Using very fine instruments, the dentist cleans the canals, gently widens them, and then disinfects them. Once this step is complete, the canals are filled with a soft, safe material, gutta-percha, which seals the inside of the tooth and prevents further infection.

Here is a summary of the main steps of the procedure:

  • Local anesthesia to ensure your comfort.
  • Isolation of the tooth with a rubber dam.
  • Opening of the tooth to access the canals.
  • Cleaning, widening, and disinfecting the canals.
  • Filling with a biocompatible material.
  • Temporary or permanent sealing of the tooth.

After treatment: what to expect?

It is normal to experience some sensitivity in the days that follow. Chewing may be uncomfortable, especially if the tooth was very infected or if the procedure was more complex. These sensations are generally temporary and gradually diminish. A simple pain reliever may be enough to relieve the discomfort. If the pain becomes unusual or persistent, it is important to seek medical advice.

In most cases, a permanent restoration will be suggested to protect the treated tooth. This often involves the placement of a crown, especially if the tooth is located at the back of the mouth, where chewing exerts greater pressure. If the tooth is very weakened, a post may be placed inside it to strengthen the base of the crown. A second treatment or minor surgery may also be considered if the infection persists or if certain areas could not be completely cleaned during the first procedure. These measures increase the chances of saving the tooth for the long term.

Regain comfort without giving up your tooth

Root canal treatment can relieve persistent pain while preserving what can be preserved. Rather than living with discomfort or fearing the worst, it becomes a concrete way to regain a sense of balance without having to undergo tooth extraction.
