Whether you’re experiencing persistent toothache or suspected tooth infection, our experts are ready to help with effective, personalized solutions.

What is Endodontics?
Endodontics is a specialty of dentistry focused on the treatment of diseases that affect the dental pulp, also called the tooth nerve, and the surrounding tissues.
When a tooth suffers a serious dental injury, whether due to deep cavities, trauma or fractures, the pulp can become damaged or infected.
This is where tooth root canal becomes crucial. This procedure aims to remove damaged or infected pulp, disinfect the dental canal, and seal it properly to prevent future complications.
The main objective of endodontics is to save the tooth, maintaining its structure and function, and avoiding the need for extraction.
When is Endodontic Treatment necessary?
There are several situations in which it may be necessary to resort to endodontics to perform tooth root canalization. The most common symptoms that indicate the need for this treatment include:
A persistent pain that can range from mild to unbearable, often aggravated by pressure or chewing.
If you feel pain when eating hot, cold, or sweet foods or drinks, it may be a sign that the pulp of the tooth is compromised.
gums or face: Serious infections can lead to the development of abscesses, causing swelling and discomfort.
A tooth that has suffered a dental injury or an infection in the pulp may change colour, becoming darker.
When caries reaches the pulp, endodontic treatment is often necessary to remove the infected tissue.

If any of these symptoms manifest, it is essential to seek help from an endodontics specialist as soon as possible.

The Process of Dental Root Canal
Tooth root canal is a relatively simple and effective procedure, but it requires precision and specialized care. Here is an overview of the steps that make up this treatment:
Diagnosis
Before starting treatment, the dentist makes a detailed evaluation of the tooth through
clinical examinations and radiographs, for
determine the extent of the injury or infection
in the dental pulp.
Anaesthesia
Location
To ensure maximum comfort during the procedure, local anesthesia is applied to the affected area. Thus, the patient will not feel pain during the intervention.
Access to
Dental Root Canal
The dentist creates a small opening in the tooth to access the pulp and root canals. This opening allows you to remove damaged or infected tissue.
Cleaning and
Disinfection
Using specialized instruments, root canals are thoroughly cleaned and disinfected to eliminate any tissue debris and bacteria that may be present.
This step is essential to avoid future infections.
Filling
and sealing
After cleaning, the canals are filled with a biocompatible material, typically a substance called gutta-percha. The filling helps seal the dental canal, preventing bacteria from re-entering.
Restoration
Depending on the condition of the tooth, it may be necessary to place a dental crown or other type of restoration to protect and strengthen the treated tooth. The crown provides an extra layer of protection, preventing fracture of the root canal tooth.
At Clínica Medicis Dental, we use advanced technologies to make tooth root canal treatment comfortable and efficient, preserving your natural tooth and ensuring a long-lasting solution.

The Importance of Dental Root Canal
Many people may feel apprehensive about the idea of having a tooth root canal removal, but it is important to remember that this procedure is often the only way to save a severely damaged tooth. Leaving an infected tooth untreated can lead to more serious complications, such as:
The infection can spread to surrounding bones and other teeth, causing wider health problems.
An untreated infection can result in the formation of an abscess, which is a painful pocket of pus that develops at the root of the tooth.
If the infection progresses without treatment, it may be necessary to extract the tooth.

Care after dental root canal
After performing a tooth root canal, it is normal for the tooth to be sensitive for a few days, especially when chewing or touching the treated area.
This discomfort is temporary and can be controlled with painkillers recommended by the dentist. However, it is essential to follow the post-treatment instructions provided by your dentist to ensure a quick and effective recovery.
Here are some important precautions to take after endodontic treatment:
hard or sticky foods in the treated area until the tooth is completely restored.
brushing your teeth twice a day and flossing regularly to prevent further infections from developing.
for check-ups, ensuring that the treated tooth remains healthy and functional.
If an additional restoration, such as the placement of a crown, is required, it is important that it is done as soon as possible to protect the root canal tooth and prevent fractures.
