Endodontics: preserve your natural teeth
When the inside of a tooth is infected or damaged, endodontic treatment, also known as root canal treatment, can save the tooth while eliminating pain and infection. This treatment aims to treat the inside of the tooth, relieve discomfort, and preserve the natural tooth for as long as possible.
At Havre Dentaire, we perform root canal treatments with gentleness and precision, using modern techniques to ensure our patients' comfort.

Why is endodontic treatment necessary?
Root canal treatment is indicated when inflammation or infection reaches the dental pulp, i.e., the inner part of the tooth containing nerves and blood vessels. This type of damage can result from various factors or risk situations.

Situations that can lead to pulp damage:
- Untreated deep decay;
- A fracture or crack in the tooth;
- An extensive or old restoration that weakens the tooth;
- Dental trauma caused by an impact or shock.
In some cases, the pulp may be severely damaged without causing acute pain, which is why a complete dental examination is important.
Prevent complications with preventive treatment
Endodontic treatment can also be performed preventively in situations where the pulp is severely compromised or at high risk of infection but not yet infected. This allows:
- DAvoid severe pain and complications such as abscesses;
- Preserve the natural tooth before it deteriorates further;
- Ensure a solid foundation for a long-lasting restoration, such as a crown.
Without treatment, possible consequences include:
- Persistent, intense pain;
- The formation of a tooth abscess, which can spread to the bone or surrounding tissues;
- Weakening of the tooth, possibly leading to its extraction;
- Significant sensitivity to heat, cold, or pressure;
- Swelling or redness of the gum around the affected tooth.
How does root canal treatment work?
Root canal treatment is usually performed in one or two sessions under local anesthesia to ensure a comfortable and painless procedure.
Assessment and diagnosis
A clinical and radiological examination is performed to confirm the diagnosis of pulp damage and to establish an appropriate treatment plan.
Access to the pulp and removal of infected tissue
Once the tooth has been anesthetized, the dentist makes a small opening in the tooth to access the pulp. The infected or damaged tissue is then removed.
Cleaning and disinfection of the canals
The canal system is cleaned, disinfected, and mechanically prepared to remove all traces of bacteria.
Filling of the canals
The cleaned canals are filled and sealed with a medical-grade rubber material to prevent further infection.
Final restoration of the tooth
The opening is repaired with a filling. A crown is often recommended to strengthen the tooth, which has been weakened by the treatment. These steps are essential to restore the tooth's normal function and prevent it from fracturing.


Is the treatment painful?
Thanks to local anesthesia and modern techniques, root canal treatment is painless in the vast majority of cases. Patients usually feel relief quickly after the procedure, as the pain associated with the infection is eliminated.
What care is needed after endodontic treatment?
To promote healing and prolong the life of the treated tooth, here are some recommendations:
- Avoid chewing on the treated side until the final restoration is in place.
- Maintain good oral hygiene (brushing and flossing).
- Follow your dentist's recommendations for taking anti-inflammatory drugs or painkillers.
- Visit your dentist regularly so they can monitor the treated tooth.
