What is Neural Therapy?

Neural Therapy is the injection of an anesthetic, such as Procaine, into dental tissue or into scars, so that they will stop causing the sensation of pain in distant parts of the human body.  Neural Therapy is based on the idea that “interference fields” are disrupting the body’s autonomic nervous system. 

If the cause of pain is dental — such as a failed root canal or dental cavitation — the anesthetic injection will only provide temporary relief (pain and other symptoms will return after the anesthetic wears off in a few hours) and the patient will have to go to the dentist for permanent relief.  This is because the Procaine only takes the tooth “out of the circuit” temporarily. The point of doing the Procaine injection is to identify exactly which tooth is causing the distant pain.

If the cause of pain is a scar, often one anesthetic injection makes the pain disappear permanently. This is because the Procaine “seals the frayed nerves” in the area of the scar.

Criticism of Neural Therapy

According to Wikipedia, Neural Therapy is a pseudoscience that does not provide any benefit. Quackwatch calls it a “questionable treatment.”

As the owner of this website, I personally do not care what Wikipedia and Quackwatch have to say. Quackwatch is run by atheists. I am not an atheist. I believe in God.

For someone who is in chronic pain, and for whom conventional treatments have not provided sufficient relief, it might make sense to try Neural Therapy. If people did not get good results from Neural Therapy, it wouldn’t be so popular in places like Europe and South America. And once you experience it for yourself, you cannot turn your back on the truth.

The few health practitioners that practice Neural Therapy would like to see lots of properly designed studies. Unfortunately, they do not have the funding to make this happen. And those who can afford to do studies typically have no incentive to them, as there is no money in it (in fact, they would probably lose money).

A Dental Problem is almost always also a Scar

Think about it: if you had a tooth extracted, you obviously had to undergo dental surgery to take that tooth out. You most likely had to have stitches, which means you had a surgical wound that now has a scar. Therefore, if that tooth is the cause of your distant pain, say in your arm or your foot, a Procaine injection into that tooth socket will do both of the following things: (1) take that tooth out of the circuit, and (2) seal the frayed nerves in that scar. Typically, what this means is, after the Procaine anesthetic wears off, and the pain in your arm or your foot or other body part returns, it is usually noticeably less pain than you had before. You are definitely still in pain, which is why you still need to go see a dentist, but it is less pain because the scar has been addressed.

Why can’t a Procaine injection get rid of distant pain caused by a Dental Problem?

The reason the Procaine anesthetic cannot permanently address the tooth is because, most likely, you have decay inside your tooth, or in the bone around it (this is called a dental cavitation), and that needs to be cleaned out by a dentist. Until you see a dentist, that decay will remain in your body and continue to cause distant pain.

Important information about Dental Cavitations Surgery: What to look for in a dentist

Not all dentists know about dental cavitations and how to treat them. That may sound strange, but that is the current state of the dental profession. Many dental schools still do not teach dental students about the existence of dental cavitations and how to treat them. The particular kind of dentist that is ideal for this surgery is one who has completed a residency in oral and maxillofacial surgery, but shockingly, if you call your local oral surgeons near you, there is a high chance the person who answers the phone will say something like “We don’t know what dental cavitations are.” This is what happened to me! Here is a lesson learned. I started out trying to find an oral surgeon who treats dental cavitations. I focused on an oral surgeon because, while a general dentist can do some types of oral surgery, sometimes it is best to consider going to a dentist that specializes in oral surgery (an oral surgeon. I used the American Association of Oral and Maxillofacial Surgeons Website, called “myoms.org,” to try to find an oral surgeon near me, see https://myoms.org/why-choose-an-oms/oral-surgery-vs-oral-surgeon/. When I went through the search results and called these oral surgeons, I was told they didn’t know what dental cavitations were! They had no idea what I was talking about!

To recap, if you go to the “myoms.org” website and search for an oral surgeon in your zip code, when you go through the results and call the oral surgeons listed in your local area, you may find that that they tell you that they don’t know what a dental cavitation is. That is why you may need to consider traveling out of state to find an oral surgeon that treats dental cavitations.

Given the difficulty in finding someone who treats dental cavitations, you may also need to consider going to a regular dentist, not an oral surgeon, if that regular dentist says that they can treat dental cavitations.

As explained on the List of Dentists that do Cavitations Surgery webpage, there are two ways to become an oral surgeon. Some oral surgeons just use the credential “DDS” (they could use “DDS, OMFS” or “DDS, OMS", but most of them don’t), so you will have to read their bio to confirm they completed a residency in oral surgery. Other dentists use the credential “DDS, MD,” but again, you will have to read their bio to confirm that their “MD” was specifically about oral surgery (and included a residency in oral surgery). In general, a dentist with the credentials “DDS, MD” can usually diagnose and treat a broader range of oral and maxillofacial issues than a “DDS, OMFS” or “DDS, OMS.”

And you should also know that you can see a dentist that has a DDS degree who works together with another dentist that is an oral surgeon (they would both be present during your dental surgery).

Bottomline, a dentist with just a DDS degree is officially only an expert in operating on teeth and gums (they can treat HOLES IN A TOOTH). Such a person is not a recognized expert on operating on bone in your face and head. A dentist with the additional OMFS or OMS or MD credential is a recognized expert on operating on bone in your face and head (they can treat HOLES IN THE BONE). Remember, A CAVITATION IS A HOLE IN THE BONE.

In any case, as of the last time I check in 2025, there are very few dentists and oral surgeons that have lots of experience treating dental cavitations. There are some dentists who state on their websites that, while they only have a DDS degree and have never completed a residency in oral and maxillofacial surgery, that they are capable of doing dental cavitations surgery.

Again, there are lots of oral surgeons that do not treat cavitations! It is not even on their menu of services! Or if they do treat cavitations, it is not a common procedure for them, so they don’t have a lot of experience doing it.

In any case, you should research the different types of dentists thoroughly on your own before you make your decision on which type of dentist you want to see.

Speaking from my experience, I found the oral surgeon associations “myoms.org” website, https://myoms.org/, to be totally UNHELPFUL. The two websites that I think are the MOST HELPFUL in trying to find a dentist or oral surgeon that treats dental cavitations are the IAOMT website at https://iaomt.org/ and the IABDM website https://iabdm.org/. Both of those organizations expressly acknowledge the existence of dental cavitations. IAOMT came out with a Position Paper in 2024 that says dental cavitations are real, that they need to be surgically treated, and that they can cause strange health problems in other parts of the body. The IABDM website states in its Mission Statement that its practitioners do “Cavitation surgery of dental focal infections” (dental cavitations), see https://iabdm.org/about-iabdm/mission/.

If you call a local dentist or oral surgeon, and the office person says they don’t know what a dental cavitation is, that they don’t know what you are talking about, tell them the ICD Codes and Medical Billing Codes explained elsewhere on this webpage. If they still don’t know what you are talking about, end the call and move on to try to find another dentist or oral surgeon.

What happens during Dental Cavitations Surgery? What exactly does the Dentist or Oral Surgeon do?

There doesn’t seem to be just one approach for treating dental cavitations. Some dentists start by cutting open the tooth socket (or if you still have a tooth there, like a Root Canal Tooth, they extract that tooth and then clean out the ligament underneath), drilling through the cortical bone until they reach the mushy dead bone “dental cavitation” area, scoop out the mushy bone with a tiny spoon called a Curet Tool, then inject Ozone Gas into the dental cavitation with a syringe (sometimes there is no needle on the end, and sometimes there isn’t), then fill the dental cavitation with Bone Graft Material (cadaver bone graft or synthetic bone graft), then put a “protective membrane” on top (either Animal Collagen Membrane or your own body’s Platelet Rich Fibrin “PRF” or a Teflon Membrane), then suture the gums on either side to hold the Membrane in place. Other dentists like to use a laser to debride the dental cavitation. Other dentists don’t use any bone graft, believing that just packing the dental cavitation with your own PRF is enough to stimulate your body to grow new bone in that area.

For more details on what exactly happens during dental cavitations surgery, see the webpage on What does a dental cavitation look like?, and scroll down to the videos at the bottom.

Many years ago, Dr. Rowen used to send patients to Dentist Dr. Silvano Senn in California. In this video posted March 20, 2013, Dr. Rowen interviews Dr. Senn, at timestamp 3:40, Dr. Senn explains how he performs Root Canal Tooth Extraction and Dental Cavitations Surgery, https://www.youtube.com/watch?v=DG9cJgCM2tM&t=72s. Dr. Senn explains how he gives ozone injections before removing the tooth, then he removes the Root Canal Tooth, then he removes the ligament, then he does ozone injections again, then he scrapes out the bad mushy bone, then he does ozone injections again, and then he says that he does not put any bone graft because it “could disturb this field,” then he does the sutures, and that’s it.

And for what its worth, a woman named Susan Luschas aka Debug Your Health Lady posted a video and article in 2016 on Lessons Learned From Dental Cavitations Surgery, see https://www.youtube.com/watch?v=IYu9rrGeslo and https://debugyourhealth.com/cavitation-surgery/#Find-Awesome-Practitioner. She went to Dr. Robert E. Jarvis, Oral Surgeon in California, for her dental cavitations surgery. Note, it appears that Dr. Jarvis retired in 2016 and sold his practice to another dentist, so he is no longer working anymore. Also, Dr. Rowen used to send patients to Dr. Jarvis, so Dr. Jarvis is mentioned in some of Dr. Rowen’s videos. In any case, according to this woman, she believes that the dentist or oral surgeon “must do ozone injections immediately after stitching up the surgery site,” and that, after the surgery, they must have the patient come in once a week for 10 weeks to get ozone injections into those dental cavitation sites. She also says that the dentist or oral surgeon should give you a Vitamin C IV drip during the dental cavitations surgery. And she says that they should use the anesthetic Carbocaine. You should discuss all this with your dentist or oral surgeon before you decide to let them to do dental cavitations surgery on you.

Is Neural Therapy covered by insurance?

Typically, Neural Therapy is not covered by insurance, see for example, Blue Cross Blue Shield of South Carolina, whose website states that “Neural therapy is considered INVESTIGATIONAL for all indications,” https://www.southcarolinablues.com/web/public/brands/medicalpolicy/external-policies/neural-therapy/. But I have not checked all insurance companies policies, so you should ask your insurance about it.

Dental Problems means Root Canals, Tooth Extractions, & Cavitations (and Mercury Amalgam Fillings)

What do we mean by “dental problems”? We are talking about root canals, tooth extractions, and dental cavitations. Mercury Amalgam Fillings can also cause distant health problems.

A ROOT CANAL is a dead tooth. It attracts bad stuff like bacteria. But because they removed the nerve inside the tooth, you don’t feel any pain. You also don’t have blood supply to that area, which means you don’t get inflammation either. You have no idea that you have an infection, but you do.

A TOOTH EXTRACTION sometimes results in a piece of dead tooth left behind. Like a Root Canal, it attracts bad stuff like bacteria.

Both Root Canals and Tooth Extractions can lead to DENTAL CAVITATIONS.

A DENTAL CAVITATION occurs when infection spreads from the root of the tooth (or what is left of the tooth, such as a piece of dead tooth) into the bone. This is what a dental cavitation looks like. There are other names for Dental Cavitation. If you ask a dentist office about Dental Cavitations, and they say they don’t know what you are talking about, tell them you are talking about JAWBONE OSTEONECROSIS, also called NEURALGIA-INDUCING CAVITATIONAL OSTEONECROSIS (NICO). Also, tell them that the ICD-10 CODE for dental cavitations is M87.08 (Idiopathic aseptic necrosis of bone that is not drug-related and not trauma-injury related) or M87.38 (Other secondary osteonecrosis due to causes not listed in other ICD codes) or M87.88 (Idiopathic necrosis of bone that is not drug-related and not trauma-injury related) or M87.9 (Idiopathic necrosis of bone due to cause unknown), see https://www.icd10data.com/ICD10CM/Codes/M00-M99/M86-M90/M87-/M87.180. Also, tell them the type of procedure that you are looking for is dental cavitations surgery, which has the Medical Billing Code D7550 (Partial Ostectomy/Sequestrectomy for Removal of Non-Vital Bone) or D7953 = Bone Replacement Graft.

There is a documentary called Root Cause (2019). It used to be on Netflix.  This documentary was about how Root Canals can cause disease and pain in other parts of the body (e.g., breast cancer, rheumatoid arthritis in joints, back pain, etc).  The American Dental Association (ADA), the American Association of Endodontists (AAE), and the American Association of Dental Research (AADR) sent a letter to Netflix asking them to take the documentary down for "spreading misinformation."  These associations also filed a class action lawsuit, as explained by Dentist Dr. Curatola in this clip. Netflix capitulated and removed the documentary.  But it is still available for free on YouTube. The ADA, AAE, and AADR never proved their allegations of misinformation in court. At best, all they can say that there is evidence in the form of published scientific studies (which they are not willing to do).

Dawn Ewing is a Dental Hygienist in Texas that tries to educates people about Root Canals. Her website is https://drdawn.net/. See also her book called Let the Tooth Be Known (2021). See also Dawn Ewing’s lecture for IAOMT in 2021, https://www.youtube.com/watch?v=3AicWRT9TaA. The Weston Price Foundation interviewed Dawn Ewing in 2023, https://www.westonaprice.org/health-topics/interview-with-dawn-ewing-should-i-get-a-root-canal/#gsc.tab=0.

In March 2001, the International Academy of Oral Medicine & Toxicology (IAOMT) released the IAOMT Status Report on Endodontic Therapy, which sets forth its position on Root Canals. This paper states that microorganisms can persist in root canals, and that “non-vital teeth can present a systemic health risk to some patients.”

In February 2024, the International Academy of Oral Medicine & Toxicology (IAOMT) released a position paper on Dental Cavitations. The paper is called IAOMT Position Paper on Human Jawbone Cavitations (February 2024). Contributors to this Position Paper include Dentist Dr. Stuart Nunnally DDS, who is in Texas. IAOMT actually came out with a position paper on dental cavitations in 2014 (written by Dr. Nunnally), so this 2024 position paper is an update of that 2014 position paper. The IAOMT Position Papers state that dental cavitations are real, that they need to be surgically treated, and that they can cause strange health problems in other parts of the body.

The International Academy of Biological Dentistry and Medicine (IABDM) website states in its Mission Statement that its practitioners do “Cavitation surgery of dental focal infections” (dental cavitations), see https://iabdm.org/about-iabdm/mission/.

Here is a list of dentists that I know do dental cavitations surgery.

Is Dental Cavitation Surgery covered by insurance?

Typically, dental cavitation surgery is not covered by insurance. I have not checked all insurance companies’ policies, so you should ask your insurance about it. I can tell you that both my health insurance and dental insurance do NOT cover dental cavitation surgery.

Mercury Amalgams in Dental Cavity Fillings & Health Issues

Occasionally, you may see videos in the Video Testimonials that involve Mercury Amalgam Dental Cavity Fillings in the person’s story. If you want to learn more about how these types of fillings might be linked to certain conditions, see https://iaomt.org/.

Diagnosis Method: How does a doctor diagnose exactly which dental issue (tooth) or body scar might be causing distant pain?

The diagnosis aspect of Neural Therapy involves applied kinesiology (aka muscle testing). To learn more, please see Diagnosis Method.
