Root canal myths can make patients delay treatment they may actually need. Stories about severe pain, illness, extraction, or a “dead tooth” can create fear before a dentist has even assessed the problem. Yet modern root canal treatment is designed to treat disease inside a tooth while preserving it when the tooth is restorable. Pain is not always present, and treatment does not automatically mean that a tooth is lost or that the procedure will be unbearable. Patients searching for root canal treatment near Kenyatta Road can benefit from separating common misconceptions from evidence-based dental information.
What Is Root Canal Treatment Actually For?
Root canal treatment is used when the pulp inside a tooth becomes inflamed or infected. Deep decay, trauma, cracks, repeated dental procedures and other forms of damage can affect the pulp. During treatment, the diseased pulp is removed, the internal canal system is cleaned and shaped, and the space is filled and sealed.
The aim is not simply to remove a “nerve.” The broader goal is to control disease within the tooth and preserve a natural tooth that can still be restored and function. The American Association of Endodontists describes root canal treatment as a way to treat inflammation or infection while saving the natural tooth.
Myth 1: Root Canal Treatment Is Extremely Painful
Fact: Modern root canal treatment is intended to relieve dental pain, not create unbearable pain.
Much of the reputation surrounding root canals comes from older experiences and stories repeated over many years. Today, local anaesthesia is used to numb the area before treatment. The NHS explains that local anaesthetic is normally given so the patient does not feel pain during the procedure.
That does not mean every patient has exactly the same experience. The tooth may already be painful because of inflammation or infection, and individual pain responses differ. Some tenderness or soreness can also occur after treatment while the surrounding tissues settle.
A better expectation is that modern root canal treatment should be performed with appropriate pain control, while temporary post-treatment discomfort remains possible. A dentist can assess significant or persistent symptoms rather than assuming that discomfort is normal indefinitely.
Myth 2: Extraction Is Better Than Root Canal Treatment
Fact: Extraction and root canal treatment solve a dental problem in different ways, and neither is automatically right for every tooth.
Root canal treatment attempts to preserve a natural tooth that can be predictably restored. Extraction removes the tooth. Once a tooth is removed, the missing space may eventually require replacement depending on its position, function and the patient’s circumstances.
The American Association of Endodontists notes that preserving a natural tooth can avoid some of the additional restorative treatment associated with replacing an extracted tooth.
However, saving every tooth is not possible or appropriate. A tooth that cannot be predictably restored may require extraction.
| Consideration | Root Canal Treatment | Tooth Extraction |
|---|---|---|
| Main goal | Preserve a restorable natural tooth | Remove the affected tooth |
| Natural tooth retained | Yes | No |
| Internal pulp treated | Yes | Tooth removed |
| Future replacement | May not be required if the tooth remains functional | May be considered depending on circumstances |
| Treatment choice | Depends on diagnosis and restorability | May be needed when restoration is not predictable |
Myth 3: Root Canal Treatment Causes Illness
Fact: Current scientific evidence does not support the claim that properly performed root canal treatment causes systemic disease.
This misconception is largely connected to an old “focal infection theory,” which suggested that bacteria associated with treated teeth could cause disease elsewhere in the body. Modern evidence and contemporary endodontic practice do not support that historical claim. The American Association of Endodontists’ updated 2026 safety information states that there is no valid scientific evidence linking endodontically treated teeth with systemic disease.
Claims that root canals cause cancer, heart disease, autoimmune disease or general systemic toxicity should therefore not be presented as established facts.
Myth 4: A Root Canal Kills the Tooth
Fact: Root canal treatment removes the pulp, but the natural tooth can remain in place and continue to function.
The pulp contains nerves, blood vessels and connective tissue inside the tooth. When diseased pulp is removed, the tooth no longer has living pulp tissue inside it. That is very different from saying that the tooth becomes useless.
A fully developed tooth can remain supported by the surrounding tissues and continue to take part in normal chewing. The treated tooth may need an appropriate restoration to protect its remaining structure, depending on its condition.
Myth 5: A Root Canal Is Only Needed When a Tooth Hurts
Fact: A tooth can have significant pulp disease without producing obvious or persistent pain.
Pain can certainly be a reason for dental assessment. Other possible signs include sensitivity, pain when biting, swelling, tenderness, discolouration or an abscess. However, symptoms vary, and some dental problems can be discovered during examination or imaging before a patient experiences severe symptoms.
Myth 6: If the Pain Stops, the Tooth Is Healed
Fact: The disappearance of pain does not necessarily prove that the underlying dental problem has resolved.
Dental symptoms can change as inflammation or infection develops. A painful tooth may become less noticeable without the underlying disease being successfully treated. Waiting for symptoms to disappear can therefore create false reassurance.
Myth 7: Root Canal Treatment Is Always Completed in One Appointment
Fact: The number of appointments varies.
Treatment can depend on the tooth involved, its anatomy, the presence of infection, the complexity of the case and clinical findings. The NHS notes that root canal treatment usually takes two or more appointments.
At Ruby Smiles Dental Clinic, the clinic-provided treatment structure supplied for this article is two appointments for anterior teeth, two appointments for premolars and three appointments for molars. Payments are arranged in two instalments for anterior and premolar treatment and three instalments for molar treatment.
Myth 8: Root Canal Treatment Always Fails
Fact: Root canal treatment is an established treatment, but no responsible dental treatment should be presented as guaranteed.
Treatment outcomes depend on diagnosis, the condition of the tooth, cleaning and sealing of the canal system, restoration, oral hygiene and follow-up. Some teeth heal successfully, while others can experience persistent or recurrent problems.
The AAE describes endodontic treatment as effective and established, while its current safety information continues to emphasize evidence-based treatment rather than guarantees.
Myth 9: A Root-Treated Tooth Will Never Need Treatment Again
Fact: A treated tooth can still develop dental problems later.
New decay, leakage around a restoration, fracture, restoration failure or persistent disease can affect a tooth that has previously received root canal treatment. Root canal treatment does not make the tooth immune to future dental problems.
Maintaining oral hygiene, protecting the tooth with the appropriate restoration and attending dental reviews can help the dental team identify problems before they become more serious.
Myth 10: Root Canal Treatment and Tooth Extraction Are the Same
Fact: They are fundamentally different treatments.
Root canal treatment attempts to remove diseased pulp while retaining the natural tooth. Extraction removes the tooth completely. The AAE explains that extraction can create a need for replacement options such as a bridge, implant or removable prosthesis depending on the circumstances.
The decision should therefore consider whether the tooth is restorable, how much healthy structure remains, its function and the patient’s overall dental situation. Choosing extraction simply because of fear about root canal treatment may overlook the possibility of preserving a natural tooth.
Is Root Canal Treatment Safe?
Current evidence supports root canal treatment as an established dental treatment. Modern care uses diagnostic assessment, local anaesthesia, cleaning and sealing techniques, infection-control measures and appropriate restoration.
The AAE’s updated 2026 safety information specifically addresses misinformation surrounding root canal treatment and states that there is no valid scientific evidence linking endodontically treated teeth with systemic disease.
What About Recovery After a Root Canal?
Recovery is usually manageable, although temporary tenderness or soreness can occur. The NHS notes that the area around the treated tooth may feel swollen or sore for a period after treatment and recommends follow-up and continued care of the teeth and gums.
Patients should follow the instructions provided by their dental team, attend recommended follow-up appointments and seek assessment if symptoms are severe, persistent or getting worse rather than improving.

Ruby Smiles Dental Clinic’s supplied root canal prices are KSh 20,000 for anterior teeth, KSh 20,000 for premolars and KSh 25,000 for molars. The supplied treatment structure is two appointments for anterior teeth, two for premolars and three for molars, with payments arranged across the respective appointments.
Frequently Asked Questions About Root Canal Myths
Is root canal treatment painful?
Modern root canal treatment is performed using local anaesthesia to control pain during treatment. Some soreness or tenderness may occur afterward, so it is more accurate to say that modern treatment is designed to make the procedure manageable rather than promising that nobody will experience discomfort.
Is root canal treatment safe?
Current evidence supports root canal treatment as an established dental treatment, and current AAE evidence does not support claims that properly performed root canal treatment causes systemic disease. Individual treatment risks should still be discussed with a dentist.
Does a root canal kill the tooth?
The pulp is removed during treatment, but the natural tooth can remain present, supported by surrounding tissues and functional.
Is extraction better than a root canal?
Not automatically. Root canal treatment may preserve a restorable natural tooth, while extraction removes it. The appropriate choice depends on diagnosis and whether the tooth can be predictably restored.
Can a tooth need a root canal without pain?
Yes. Symptoms vary, and some pulp problems may have limited symptoms. A dental assessment is more reliable than using pain alone to determine whether treatment is needed.
Does root canal treatment cause illness?
Current scientific evidence does not support the claim that properly performed root canal treatment causes systemic disease.
How many appointments does a root canal take?
It varies. The NHS says treatment usually takes two or more appointments. At Ruby Smiles, the supplied structure is two appointments for anterior teeth, two for premolars and three for molars.
What happens if I avoid root canal treatment?
If a tooth has disease that requires root canal treatment and is left untreated, the condition may progress and can potentially lead to further pain, infection or tooth loss. The NHS notes that an untreated infected tooth may eventually need extraction.
