A root canal, also known as endodontic treatment, is a procedure that allows a tooth affected by infection or deep decay to be saved. Although it is a safe and effective intervention, it is normal for patients to have doubts about which symptoms are normal after the treatment and which ones might indicate a problem.
At A2 Dental Mallorca, our specialist in Endodontics, Dr Anna Nilsson, explains what the post-operative period after a root canal is like, what discomfort may appear, and in which cases it is necessary to see the dentist.
What is a root canal and why can it cause discomfort?
A root canal is a treatment carried out when the pulp of the tooth, which contains nerves and blood vessels, is damaged or infected. It consists of removing the affected pulp, cleaning the root canal and sealing it with a biocompatible material to prevent future infections.
After the procedure, the tooth no longer has a nerve, so it should not hurt as it did before the root canal. However, since work has been done on the root of the tooth, it is common to experience slight discomfort during the first few days.
Normal symptoms after a root canal
The following symptoms are common and part of the recovery process:
- Mild pain or sensitivity when chewing
After a root canal, the treated area may be inflamed, which causes slight discomfort when biting or putting pressure on the tooth. This sensation usually improves within one or two weeks and can be relieved with painkillers prescribed by the dentist. - Swelling of the gum
The gum around the treated tooth may be slightly swollen or tender due to manipulation during the procedure. This is temporary and subsides with anti-inflammatory medication and good oral hygiene. - Discomfort when brushing
Some patients notice slight sensitivity in the treated area when brushing. It is recommended to use a soft-bristled toothbrush and avoid pressing too hard on the area until the sensitivity disappears. - Tooth feels different
As it has been treated internally, the tooth may feel slightly different from the rest of the teeth during the first few days. This is a normal sensation and adjusts over time.
Symptoms that could indicate a problem
Although mild discomfort is normal, there are symptoms that may indicate a complication and require a visit to the dentist.
- Severe pain that does not improve with painkillers
If the pain is strong, persistent and does not improve with medication, it could be a sign of severe inflammation or a residual infection. - Severe swelling or abscess
If the swelling does not decrease or increases over time, especially if there is a bump on the gum or discharge, it could be a sign of an infection that requires urgent attention. - Fever or general discomfort
Fever may indicate a developing infection. In such cases, it is essential to visit the dentist to avoid complications. - Fractured tooth
A tooth that has undergone root canal treatment is more fragile than a healthy tooth, so if it fractures, it may cause pain and compromise its preservation. In many cases, it is recommended to place a dental crown to protect it.
How long does It take for a tooth to heal after a root canal?
Recovery time varies depending on the patient and the complexity of the case, but in general:
- Mild discomfort: May last between 3 and 7 days.
- Chewing sensitivity: Can persist for up to 2 weeks.
- Mild swelling: Usually resolves in a few days with anti-inflammatory medication.
- Complete internal healing: May take several weeks, although the patient can usually return to normal life shortly after the treatment.
It is important to avoid chewing hard foods with the treated tooth until the dentist confirms that recovery is complete.
Can a root canal fail? Options if the pain persists
In some cases, a root canal may not fully resolve the problem. This can occur if:
- There are additional root canals that were not treated.
- The tooth has an undetected fracture.
- Reinfection occurs due to leakage in the tooth’s seal.
When a root canal is not successful, the possible options include:
- Retreatment: The sealing material is removed, and the canal is cleaned again.
- Apicoectomy: A minor surgical procedure is performed at the root tip to remove the infection.
- Tooth extraction and implant: When the tooth cannot be saved, it is extracted and replaced with a dental implant as a definitive solution.
Aftercare following a root canal to prevent complications
For a smooth recovery, it is important to follow these recommendations:
- Take the prescribed medication as directed by the dentist.
- Avoid very hard or sticky foods during the first few days.
- Do not chew with the treated tooth until the dentist gives approval.
- Maintain good oral hygiene by brushing the area gently.
- Attend follow-up appointments to ensure proper healing of the tooth.
Is It better to extract the tooth or have a root canal?
Many patients wonder whether it is better to undergo a root canal or directly extract the tooth and place a dental implant. The answer depends on the specific case:
- If the tooth has a solid structure and can be saved, a root canal is the best option. Preserving natural teeth is always preferable when possible.
- If the tooth is too damaged or fractured, a dental implant may be the better solution, as it provides long-term stability.
At A2 Dental Mallorca, we use advanced techniques for endodontic treatment, such as rotary instrumentation, magnification-assisted endodontics, and thermoplastic sealing techniques to achieve the safest outcome for the patient. We also carry out a detailed study using internal 3D imaging of the tooth (CBCT or dental CT scan) to determine the best option for each patient, always prioritising the conservation of natural teeth when viable.
