Myths And Facts About Root Canals
We clarify common myths about root canals and tooth pain, helping patients understand the truth about modern endodontic treatment, safety, and comfort during procedures.
Tooth Pain Guide
Please select from the list below the title that best reflects your pain.
Possible Problem
If the discomfort lasts only moments, sensitivity to hot and cold foods generally does not signal a problem. The sensitivity may be caused by a loose filling or by minimal gum recession which exposes small areas of the root surface.
What To Do
Try using toothpastes made for sensitive teeth. Brush up and down with a soft brush; brushing sideways wears away exposed root surfaces. If this is unsuccessful, see your dentist.
Possible Problem
Dental work may inflame the pulp, inside the tooth, causing temporary sensitivity.
What To Do
Wait four to six weeks. If the pain persists or worsens, see your dentist.
Possible Problem
There are several possible causes of this type of pain: decay, a loose filling, or a crack in the tooth. There may be damage to the pulp tissue inside the tooth.
What To Do
See a dentist for evaluation. If the problem is a cracked tooth, your dentist may send you to an endodontist. Cracked tooth pain comes from damage to the inner soft tissue of the tooth, the pulp. Endodontists are dentists who specialize in pulp-related procedures. Endodontic treatment, also known as root canal treatment, can relieve that pain.
Possible Problem
This probably means the pulp has been damaged by deep decay or physical trauma.
What To Do
See Dr. Black to save the tooth with root canal treatment.
Possible Problem
A tooth may have become abscessed, causing the surrounding bone to become infected.
What To Do
See Dr. Black for evaluation and treatment to relieve the pain and save the tooth. Take over-the-counter analgesics until you see the endodontist.
Possible Problem
The pain of a sinus headache is often felt in the face and teeth. Grinding of teeth, a condition known as bruxism, can also cause this type of ache.
What To Do
For sinus headache, try over-the-counter analgesics or sinus medicine. For bruxism, consult your dentist. If pain is severe and chronic, see your physician or endodontist for evaluation.
Possible Problem
Sometimes pulp-damaged teeth cause pain in other parts of the head and neck, but other dental or medical problems may be responsible.
What To Do
See Dr. Black for evaluation. If the problem is not related to the tooth, your endodontist will refer you to an appropriate dental specialist or a physician.
Myths About Root Canals
and Root Canal Pain
There are many misconceptions surrounding root canal (endodontic) treatment and whether patients experience root canal pain. The American Association of Endodontists wants you to have accurate information. As always, when considering any medical procedure, you should get as much information as you can about all of your options. Your dentist or endodontist can answer many of your questions, and if you still have concerns, it is often wise to seek a second opinion.
Myth #1—Root canal treatment is painful.
Truth—Root canal treatment doesn’t cause pain, it relieves it.
The perception of root canals being painful began decades ago but with modern technologies and anesthetics, root canal treatment today is no more uncomfortable than having a filling placed. In fact, a recent survey showed that patients who have experienced root canal treatment are six times more likely to describe it as “painless” than patients who have not had root canal treatment.
Most patients see their dentist or endodontist when they have a severe toothache. The toothache can be caused by damaged tissues in the tooth. Root canal treatment removes this damaged tissue from the tooth, thereby relieving the pain you feel.
Myth #2—Root canal treatment causes illness.
The truth: There is no valid, scientific evidence linking root canal-treated teeth and disease elsewhere in the body. A root canal is a safe and effective procedure. When a severe infection in a tooth requires endodontic treatment, that treatment is designed to eliminate bacteria from the infected root canal, prevent reinfection of the tooth and save the natural tooth.
Patients searching the Internet for information on root canals may find sites claiming that teeth receiving root canal (endodontic) treatment contribute to the occurrence of illness and disease in the body. This false claim is based on long-debunked and poorly designed research performed nearly a century ago by Dr. Weston A. Price, at a time before medicine understood the causes of many diseases.
In the 1920s, Dr. Price advocated tooth extraction—the most traumatic dental procedure—over endodontic treatment. This resulted in a frightening era of tooth extraction both for treatment of systemic disease and as a prophylactic measure against future illness.
- The presence of bacteria in teeth and the mouth has been an accepted fact for many years. But the presence of bacteria does not constitute “infection” and is not necessarily a threat to a person’s health. Bacteria are present in the mouth and teeth at all times, even in teeth that have never had a cavity or other trauma. Research shows that the healthy immune system takes care of bacteria in a matter of minutes.
- Tooth extraction is a traumatic procedure and is known to cause a significantly higher incidence of bacteria entering the bloodstream; endodontic treatment confined to the root canal system produces much less trauma and a much lower incidence and magnitude of bacteria entering the blood stream.
- There is no adequate replacement for the natural tooth – it should be saved whenever possible. Root canal treatment, along with appropriate restoration, is a cost effective way to treat infected teeth because it is usually less expensive than extraction and placement of an implant. In most cases, endodontic treatment allows patients to keep their natural teeth for a lifetime.
