Toothache is one of the most intense types of pain a human being can experience. In many cases, this pain is a sign that the tooth nerve (dental pulp) is inflamed or infected—and the solution is not to extract the tooth, but to treat and preserve it.
This is where endodontics, more commonly known as root canal treatment, comes in. This procedure eliminates the infection, relieves pain, and keeps the tooth in place, restoring comfort and functionality.
At OnlySmile, in Ponta Delgada, São Miguel, this treatment is performed using modern technology, effective anesthesia, and a care approach that prioritizes patient comfort. In this article, we explain what root canal treatment is, when it is necessary, what you can expect, and how to ensure that the treated tooth lasts for many years.
The Essentials
- Root canal treatment eliminates infections inside the tooth (pulp) and prevents extraction.
- It is indicated when there is intense pain, inflammation, infection, or a deep fracture.
- The treatment is painless, performed with local anesthesia and modern instruments.
- The treated tooth maintains normal function, provided it is restored and monitored.
- In Ponta Delgada, São Miguel (Azores), OnlySmile performs root canal treatments with microscopy and advanced endodontic techniques.

1. What is root canal treatment (endodontics)
Root canal treatment — technically called endodontics — is the procedure that removes inflamed or infected tissue from inside the tooth (the dental pulp).
The pulp contains nerves and blood vessels that, when affected by deep decay, fracture, or trauma, cause intense pain and infection.
The treatment involves cleaning, disinfecting, and sealing the tooth’s internal canals, preventing bacteria from proliferating again.
Thanks to current technology, the treatment is precise, quick, and painless.
The tooth remains in the mouth, preserving the bone and alignment of the remaining teeth — a significant advantage over extraction.
2. When is root canal treatment necessary
Root canal treatment is necessary whenever the dental pulp is compromised.
The most common causes include:
- Deep cavities that reach the nerve.
- Traumas, such as blows or falls that damage the tooth’s interior.
- Extensive dental fractures.
- Root infections, visible on X-rays.
- Intense and persistent sensitivity to heat or cold.
- Spontaneous and throbbing pain, especially at night.
When the nerve is inflamed, the pain can be unbearable. But when the nerve dies, the pain disappears — and that’s when the risk increases, as the infection can continue silently and spread to the bone.
In Ponta Delgada, it is common to receive patients who have postponed treatment out of fear, but then realize that the canal is a simple and effective solution to preserve the tooth.
3. Symptoms and warning signs
Not all dental infections cause immediate pain, but there are signs that should not be ignored:
- Pain when chewing or touching the tooth.
- Constant feeling of “pressure.”
- Swelling in the gum near the tooth.
- Change in tooth color (darker).
- Fistula (small “bump” that drains pus).
- Persistent bad taste in the mouth.
If you experience any of these symptoms, you should see a dentist as soon as possible.
Early treatment is the difference between saving the tooth and having to extract it.
Modern endodontics can resolve even advanced infections, with high success rates.
4. Step-by-step treatment stages
Root canal treatment is performed with technical rigor and is usually completed in 1 or 2 sessions.
The main stages are:
- Local anesthesia – completely eliminates pain and discomfort.
- Opening the tooth crown – a small access to the internal pulp is created.
- Removal of infected pulp – using fine and rotary instruments.
- Disinfection of the canals – application of antibacterial solutions to eliminate microorganisms.
- Sealing of the canals – hermetic filling with biocompatible material.
- Temporary or permanent restoration – protects the tooth until the crown is placed.
In more complex cases, a clinical microscope, digital X-ray, and electronic apex locators are used, which increase precision and reduce treatment time.
5. Pain and anesthesia: what you really feel
One of the biggest myths is that root canal treatment “hurts.”
In fact, with modern anesthesia and current techniques, the procedure is painless.
The discomfort felt before treatment — caused by the infection — disappears as soon as the intervention begins.
After treatment, there may be slight sensitivity in the following days, especially when chewing, but it is temporary and manageable with simple medication.
The goal is to eliminate pain, not cause it.
6. What happens if the canal is not treated
Ignoring an infected tooth is dangerous.
Without treatment, the infection can spread to the bone, gum, and even other parts of the body.
Consequences include:
- Dental abscess (purulent infection).
- Swelling and intense facial pain.
- Loss of the affected tooth.
- Risk of more serious infections if bacteria enter the bloodstream.
Moreover, extraction creates an imbalance in the bite and can lead to local bone loss.
Therefore, root canal treatment is a safe way to save the tooth and avoid complications.
7. Post-treatment care
After treatment, the tooth becomes more fragile, as it loses the pulp that nourished it.
Recommended care includes:
- Avoid chewing hard foods on the treated tooth until the final crown is placed.
- Maintain strict oral hygiene, with brushing and flossing.
- Attend the dentist’s recommended check-ups.
- Avoid smoking, as tobacco hinders healing.
In many cases, a protective crown is placed, restoring strength and aesthetics to the tooth.
By following these guidelines, the treatment is durable and safe.
8. How long does a treated tooth last
A tooth with root canal treatment can last as many years as a natural tooth, provided it is well restored and maintained.
Longevity depends on the quality of the treatment, the final restoration, and the patient’s care.
With regular check-ups and good hygiene, success rates exceed 90% after 10 years.
In many cases, the treated tooth remains functional for a lifetime.
9. Price and transparency in root canal treatment
The cost of root canal treatment depends on the number of roots and the complexity of the case.
On average:
- Incisors and canines (1 canal): €150 – €220
- Premolars (2 canals): €200 – €280
- Molars (3 or more canals): €250 – €380
At OnlySmile, the estimate is always provided in writing, with a clear explanation of each phase of the treatment.
The goal is to offer security and transparency, with no surprises in the final cost.
