How Holistic Dentists Approach Root Canals

Holistic dentists approach root canals in one of two ways. Some refuse them and pull the tooth instead, because they believe a root-filled tooth harbors bacteria that harm the body. Others do root canals with biocompatible sealers, ozone, and 3D imaging.

The research supports saving the tooth. Properly treated root canal teeth are not linked to systemic disease, and treating the infection lowers inflammation markers in the blood.

What is a holistic root canal

A holistic root canal is a standard root canal done with extra attention to materials, disinfection, and whole-body health. The steps are the same. The infected pulp comes out, the canals are cleaned and shaped, and the space is sealed.

What changes is the detail. A holistic dentist might use a bioceramic sealer instead of a resin one. They might add ozone or a laser to the disinfection step. They often take a 3D scan to find hidden canals and skip metal posts in the final restoration.

Some of those choices are now mainstream endodontics. Others have thin evidence behind them. I will separate the two below.

The bigger split is between holistic dentists who do root canals and holistic dentists who refuse them. That second group believes a root-filled tooth stays infected and makes you sick. That belief has a history, and it has been tested.

Holistic vs conventional root canal: what the evidence says

The short version: most of what a careful holistic dentist does during a root canal is fine. Refusing root canals outright is where the evidence runs out.

Why some holistic dentists avoid root canals

Some holistic dentists avoid root canals because of a theory from 1923 that was discarded by the 1950s and revived by a 2019 documentary.

The focal infection theory

In 1923, a dentist named Weston Price published research claiming that bacteria trapped in root-filled teeth caused arthritis, heart disease, and other illnesses. His solution was extraction.

For about thirty years, dentists pulled teeth on that basis. Then better studies came along. A 1951 special issue of the Journal of the American Dental Association reviewed the work and found it lacked control groups and used non-sterile methods. Practice shifted back to saving teeth.

The documentary

In January 2019, a film called Root Cause appeared on a streaming service. It argued that root canal teeth cause cancer and heart disease and pushed extraction.

The American Association of Endodontists, the American Dental Association, and the American Association for Dental Research sent a joint letter to the platforms that month. They wrote that the film’s claims had been disproven by decades of peer-reviewed evidence. The platform pulled the film within weeks.

The statistic that spread from the film, that 97% of terminal cancer patients had root canals, traces to one physician’s recollection from the 1950s. It was never a study.

Why the idea persists

It sounds plausible. A root canal tooth has no living pulp. Bacteria can survive in dentin tubules. Both of those are true.

What does not follow is harm. A well-sealed tooth with healthy bone around it is a stable tooth. The research below looked for the damage and did not find it.

What the research says about root canals and your health

The research says properly treated root canal teeth are not linked to systemic disease, and treating the infection lowers systemic inflammation.

The American Association of Endodontists states there is no valid scientific evidence linking root canals to health problems. That position rests on decades of studies.

Three findings matter most.

Cancer risk does not go up

A 2013 study in JAMA Otolaryngology looked at head and neck cancer and dental history. Patients with multiple root canal treatments had a 45% lower risk, although that difference was not statistically significant. The finding points the opposite way from the claim.

Inflammation goes down

A 2025 meta-analysis in the International Endodontic Journal pooled 16 studies with 596 patients who had infected teeth. Six months after root canal treatment, hs-CRP fell from 2.26 to 1.28 mg/L. Interleukin-1 beta fell at 12 months.

hs-CRP is the same marker your physician uses to estimate cardiovascular risk. The infected tooth was raising it. Treating the tooth lowered it.

Heart risk does not go up

A 2017 Finnish study in the same journal followed patients with root-filled teeth and found lower cardiovascular mortality in that group. That is one population study, so I hold it loosely. It fits the pattern.

The conclusion is that an untreated infection is the health risk. The root canal is the fix.

What holistic dentists do differently during a root canal

When a holistic dentist does a root canal, the differences usually show up in imaging, disinfection, materials, and the final restoration.

3D imaging

A cone beam CT scan shows the root canal system in three dimensions. It finds extra canals, cracks, and bone loss that a flat X-ray can miss. Most endodontists use it for complex cases. It is good practice, and it is standard.

Ozone and lasers

Ozone gas or ozonated water goes into the canals as an extra disinfection step. The claim is that it reaches spaces that bleach cannot.

A 2025 review in Current Oral Health Reports found ozonated solutions did not outperform sodium hypochlorite or chlorhexidine against bacteria. The authors said ozone is not indicated as a replacement. One possible benefit was less pain after treatment. If your dentist uses ozone alongside standard irrigation, it is unlikely to hurt. If they use it instead, ask why.

Bioceramic sealers

The canals are sealed with gutta-percha and a sealer. Older sealers used zinc oxide eugenol or resin. Bioceramic sealers are calcium silicate-based, set hard in moisture, and are well tolerated by bone.

Holistic practices market this as a biocompatible choice. It is. It is also what most endodontists use now.

No metal posts, metal-free crowns

After the root canal, a back tooth usually needs a crown. A holistic dentist will avoid metal posts and choose a ceramic or zirconia crown.

Alternatives to a root canal

The alternatives to a root canal are saving the nerve with vital pulp therapy, or removing the tooth and replacing it. Leaving an infected tooth alone is not an alternative.

Vital pulp therapy

When decay reaches the pulp, but the tooth is still alive, a pulpotomy removes the inflamed top portion of the pulp and caps the rest with a bioceramic material. The root stays alive.

A 2022 meta-analysis in Scientific Reports pooled 11 studies. Pulpotomy succeeded in 86% of permanent teeth diagnosed with irreversible pulpitis. In fully developed adult teeth, the rate was 83%. Biodentine outperformed older capping materials. The authors graded the certainty of evidence as very low, so the number may shift.

This is the one true conservative alternative. It only works while the pulp is alive. Once the tooth is dead or there is an abscess, the window has closed.

Extraction and implant

The tooth comes out, the socket heals, and an implant replaces it. A 2007 systematic review in the Journal of Prosthetic Dentistry found root canal-treated teeth survived at 94% and implant crowns at 97% over four to six years. Those are close. The implant costs more, takes months, and replaces a tooth you could have kept.

Some holistic dentists prefer zirconia implants over titanium. A 2023 meta-analysis found similar survival at 12 months, based on two randomized trials. Long-term data on zirconia is still thin.

Extraction and bridge

A bridge replaces the missing tooth by crowning the teeth on either side. It works, and it grinds down two healthy teeth to do it. The same 2007 review put bridge success at 90% to 93%, below both root canals and implants.

How I approach root canals in Huntersville

I do not do root canals in my office. I diagnose the tooth, try to save the pulp when that is possible, and refer the root canal itself to an endodontist I trust. Then the tooth comes back to me for the crown.

Patients looking for a holistic or biological dentist often ask about this first. Here is my position.

I try to save the nerve first

If the pulp is still alive and the inflammation is limited, vital pulp therapy is on the table. That keeps the tooth alive and skips the root canal entirely. It depends on catching the problem early.

I refer to a specialist for the root canal

Endodontists do root canals all day. They have the microscopes and the 3D imaging. Curved, calcified, and hidden canals are their everyday work. That matters more than any single material choice.

I restore the tooth metal-free

When the root canal is done, the tooth comes back to me. I build it up without a metal post and cover it with a ceramic or zirconia crown. That is the biocompatible part people are looking for, and it is how I restore every tooth.

I extract when the tooth cannot be saved

Some teeth cannot be saved. A crack below the gum, decay past the point of restoration, or bone that no longer holds the tooth means extraction. When that is the answer, I preserve the socket for a future implant, and we talk through the replacement options.

What I will not do

I will not pull a healthy root canal tooth because of a theory. If a root-filled tooth has a new infection on the X-ray, that is a reason to act. A tooth with a clean X-ray and no symptoms stays.

Who each option is for

A root canal is for

A tooth with a dead or dying pulp, enough healthy structure to hold a crown, and a root that can be cleaned. That describes most teeth that need one.

Vital pulp therapy is for

A tooth with deep decay, a living pulp, and inflammation that has not spread down the root. Younger teeth do best. Adults can qualify too.

Extraction and implant is for

A tooth with a crack below the gum, a root that is too short or too damaged, or a root canal that has failed twice. Also for someone who has decided against a root canal after hearing the evidence.

A second opinion is for

Anyone who has been told to pull a healthy root canal tooth, or told that root canals cause disease. Bring the X-rays.

Common mistakes and myths about holistic root canals

Myth: Root canals cause cancer, heart disease, or arthritis

This comes from 1920s studies with no control groups. The dental and research organizations that reviewed it called it disproven. The 2013 cancer data and the 2025 inflammation data both point the other way.

Myth: A root canal tooth is a dead tooth that rots in your jaw

The pulp is gone. The tooth itself, the bone around it, and the ligament holding it are alive and supplied with blood. A sealed, crowned root canal tooth functions for decades.

Mistake: Pulling a healthy root canal tooth to be safe

Extraction is permanent. It costs bone, and the replacement costs thousands of dollars. A tooth with no symptoms and a clean X-ray carries no documented risk.

Mistake: Choosing a dentist by the word holistic alone

Some holistic dentists do excellent, evidence-based root canals. Some refuse them. The label does not tell you which. Ask what they do when a tooth is infected and why.

Myth: Ozone makes a root canal safe, and bleach makes it toxic

Sodium hypochlorite has decades of outcome data behind it. Ozone did not beat it in head-to-head testing. The irrigant is not what makes a root canal succeed or fail. The seal, the restoration, and the skill of the operator do.

Mistake: Waiting for the tooth to stop hurting

An abscessed tooth can stop hurting when the nerve dies. The infection is still there and still spreading into bone. Pain that goes away on its own is a reason to call.

What if my situation is different

What if I already have a root canal tooth and I am worried about it

Have it X-rayed. A tooth with healthy bone around the root and no symptoms is fine. If the X-ray shows a new dark area at the root tip, the canal may need retreatment. That is a known, fixable problem.

What if my holistic dentist told me to extract it

Ask for the X-ray and the reason. If the answer is a crack, a failed retreatment, or a root that cannot be cleaned, extraction may be right. If the answer is that all root canals are dangerous, get a second opinion.

What if I want a root canal but with the extra steps

Ask the endodontist about bioceramic sealers, CBCT imaging, and a metal-free buildup and crown. Most will say yes to all three without needing the word holistic.

What if the tooth is a front tooth

Front teeth have one straight canal and are among the easiest root canals. They rarely need a crown afterward. Pulling one to avoid a root canal is a hard trade to justify.

What if I am pregnant

An infected tooth is a bigger risk during pregnancy than a root canal is. Treatment is safe in any trimester, and the second is usually the most comfortable. Your dentist and your OB can coordinate.

Frequently asked questions

Do holistic dentists believe in root canals?

Some do, and some do not. Many holistic and biological dentists perform or refer for root canals and use bioceramic sealers, 3D imaging, and metal-free restorations. Others refuse root canals and extract the tooth, based on a theory from the 1920s that modern research has not supported. Ask any office directly what they do when a tooth is infected.

Is there a holistic alternative to a root canal?

The one conservative alternative is vital pulp therapy, which saves the living part of the nerve and succeeds in roughly 83% to 86% of eligible teeth. It only works while the pulp is alive. The other option is extraction followed by an implant or bridge, which replaces the tooth. Leaving the infection alone is not an alternative.

Why do dentists try to avoid root canals?

Dentists try to avoid root canals by catching decay early, when a filling or vital pulp therapy can still save the nerve. A tooth that keeps its nerve is stronger and lasts longer. That is different from avoiding a root canal once the pulp is dead. At that point the choice is a root canal or an extraction.

Can you fix a root canal naturally?

No. Once the pulp is infected or dead, no rinse, supplement, or diet change can sterilize the inside of a tooth. Salt water and clove oil ease pain for a day or two while the infection spreads into bone. The natural options are to save the nerve early with vital pulp therapy, or to treat the tooth and keep it.

What kills root canal bacteria?

Mechanical cleaning of the canals plus sodium hypochlorite irrigation, which has decades of outcome data. Calcium hydroxide placed between visits adds to the effect. Ozone and lasers are marketed as alternatives. A 2025 review found ozone did not outperform sodium hypochlorite against bacteria. The seal placed afterward matters as much as the disinfectant, because it keeps new bacteria out.

What to do next

If a tooth hurts, has been diagnosed as needing a root canal, or has an old root canal you are unsure about, book an exam. I will take the X-rays and test the tooth. Then I will tell you whether the nerve can be saved, whether the tooth needs a root canal, or whether it needs to come out.

If it needs a root canal, I will refer you to an endodontist and handle the crown afterward. If it needs to come out, tooth extraction in Huntersville is done here, with socket preservation so an implant stays possible. Either way, you will hear what the evidence says, and the choice will be yours.
