Everything that is placed in a tooth,

either temporarily or permanently,

will migrate out of the tooth

and be transported to every part of the body

Ask your dentist what materials they plan to use for the root canal procedure to clean, disinfect and then seal into your tooth as a filling.

Then go and look at what’s in these materials and their effects on your health. Most are listed here. If they’re not listed here, simply search “MSDS + Product Name”

Medical and dental students, in their second year of university, had to study anatomy. In the 1970s and 80s, this included weekly dissections of cadavers. These bodies were preserved in formaldehyde. The students who were made sick from being in the dissecting rooms, were given no exemption or support. They were just written off as being ‘squeamish’! For the dental students the exposure was compounded by exposure to mercury in the clinics of the dental hospitals. NONE OF US WERE TOLD!

Papers published in dental journals will often conclude that these materials are ‘Biocompatible’. Their use is promoted by ALL dental schools. Dentists rarely read the MSDSs for these materials and blindly do as they are told by their professors. The professors and deans rarely read or pay attention to the MSDSs for these materials. Only the manufacturers set the warnings on these materials.

To dentists who are still doing Root Canals – it’s time to think about what you’re implanting into people’s bodies!

Buckley’s Formocresol – A VERY SPECIAL MATERIAL – Formalin & Cresol

This material was created in the early 1920’s by the past president of the American Dental Association, Dr Buckley. The very same person who tried to rubbish the work of Dr Weston Price. This poison is placed into baby teeth (ie young children) in the procedure called pulpotomy and is sealed in permanently!   It will leak into the child’s body 24/7. (RG Comment)

From the MSDS;

Contains: Cresol, Formaldehyde Carc. Harmful by inhalation. Toxic in contact with skin and if swallowed. Causes burns.  Limited evidence of a carcinogenic effect.  May cause sensitization by skin contact.  Keep locked up and out of the reach of children.

Potential Health Effects:
Eyes: Causes burns to eyes with redness, pain and tearing. Eye damage is possible.
Skin: If spilled on skin, numbness is followed promptly by pain and reddening. Chemical burns are possible. Toxic when absorbed through skin with symptoms similar to ingestion. May cause an allergic skin reaction.
Ingestion: Swallowing causes intense burning of mouth and throat. Cause epigastric pain, muscular weakness, headache, dizziness, nausea, vomiting, collapse, shock, CNS depression, and death. May cause injury to the kidneys, liver, heart, pancreas, and spleen. Symptoms may be delayed.
Inhalation: Inhalation of mists may cause mucous membrane and upper respiratory tract irritation. Toxic when inhaled with symptoms similar to ingestion. May cause an allergic reaction.

Chronic Health Effects: May cause injury to the kidneys, liver, heart, pancreas, lungs, and spleen.
Carcinogenicity: Formaldehyde is listed by IARC as “Carcinogenic to Humans”, (Group 1), by NTP a “Known to be a Human Carcinogen”, by ACGIH as a “Suspected Human Carcinogen” (A2), by the European Union as a Carcinogen Category 3. Cresol Isomers- Possible human carcinogen. Based on an increased incidence of skin papillomas in mice in an initiation-promotion study. The three cresol isomers produced positive results in genetic toxicity studies both alone and in combination. None of the components are listed as a carcinogen by IARC, NTP, OSHA, ACGIH or the EU Substances Directive.
Mutagenicity: No data available
Medical Conditions Aggravated by Exposure: Employees with pre-existing eye, skin, kidneys, liver, heart, pancreas, lungs, and spleen disorders may be at increased risk from exposure.
Reproductive Toxicity Data: No data available for mixture. In a reproductive study, rats were exposed to 0-40 ppm formaldehyde for 6 hr/days on days 6-20 of gestation. At 40 ppm, maternal toxicity was observed. Formaldehyde is slightly fetotoxic at 20 ppm. Neither embryolethal nor teratogenic effects were observed following inhalation exposure at levels up to 40 ppm.
Specific Target Organ Toxicity (STOT):
Single Exposure: Exposure to high doses of formaldehyde (>100 ppm) showed salivation, acute dyspnea, vomiting, cramps and death in laboratory animals. Mice treated with formaldehyde on skin developed severe liver damage.
Repeated Exposure: Animal data revealed a qualitative relationship between formaldehyde absorption and hepatotoxicity.
These data indicate that exposure to formaldehyde at 3 ppm or less for periods up to 6 months causes adverse effects upon the liver; higher exposure concentrations for shorter time periods produce similar effects upon the liver

Cresol

Potential Health Effects
Eye: Causes eye burns. May result in corneal injury. Contact with liquid is corrosive to the eyes and causes severe
burns. May cause conjunctivitis and keratitis.
Skin: May be absorbed through the skin in harmful amounts. May cause skin sensitization, an allergic reaction, which becomes evident upon re-exposure to this material. Causes severe skin irritation and burns.
Ingestion: May cause severe and permanent damage to the digestive tract. May cause vascular collapse and damage.
Causes severe digestive tract burns with abdominal pain, vomiting, and possible death. May cause kidney, liver
and spleen damage. Rapidly absorbed from the gastrointestinal tract. Cresols may cause abnormalities of the
central nervous system, respiratory system, spleen and pancreas.
Inhalation: May be fatal if inhaled. Irritation may lead to chemical pneumonitis and pulmonary edema. May cause liver and kidney damage. Causes severe irritation of upper respiratory tract with coughing, burns, breathing difficulty, and possible coma. Causes chemical burns to the respiratory tract. May cause headache. May cause nausea and possible vomiting.

Chronic: May cause liver and kidney damage. Repeated exposure may cause sensitization dermatitis. May cause appetite loss, diarrhea, skin abnormalities, and digestive tract disturbances.

Materials used to wash and clean the root canal

-as part of the root canal procedure.  These materials are often forced through the end of the root and into the surrounding bone with devastating consequences.

Hydrogen Peroxide

Vapors, mists, or aerosols of hydrogen peroxide can cause upper airway irritation, inflammation of the nose, hoarseness, shortness of breath, and a sensation of burning or tightness in the chest. Prolonged exposure to concentrated vapor or to dilute solutions can cause irritation and temporary bleaching of skin and hair. Exposure to vapor, mist, or aerosol can cause stinging pain and tearing of eyes.

Confirmed Animal Carcinogen with Unknown Relevance to Humans’ (A3)

Causes burns by all exposure routes

Inhalation of vapour may result in mucous membrane irritation of the nose and throat with coughing. At high levels nausea, dizziness and chemical burns to the respiratory tract.

Skin Corrosive. Prolonged or repeated contact may result in drying the skin, rash, dermatitis and chemical burns.

Ingestion Highly corrosive. Ingestion will cause severe chemical burns to the mouth and throat. The rapid releasing of oxygen can cause distension and bleeding of the mucosa in the stomach and lead to severe damage of the internal organs.

Sodium Hypochlorite

Ingestion: May be harmful if swallowed. Will cause severe irritation and corrosion (chemical burns) of the mucous membranes of the mouth, throat and gastrointestinal tract with nausea, vomiting, abdominal pain and inflammation. Systemic effects include fall of blood pressure, delirium and coma.

Eye: A severe eye irritant will cause stinging, blurring, tearing, severe pain. Causes serious eye damage. Corrosive to eyes, contact can cause corneal burns. Can result in permanent injury.

Skin: Corrosive to skin. May cause skin burns. Contact with skin will cause redness, itching, irritation, severe pain and chemical burns with resultant tissue destruction.

Inhalation: Inhalation of mists or vapours will result in respiratory irritation, cough, shortness of breath and possible harmful corrosive effects including lesions of the nasal septum, pulmonary oedema, pneumonitis and emphysema.

Inhalation causes slight to severe respiratory tract irritation and delayed pulmonary edema. Prolonged or repeated inhalation may cause allergic respiratory reaction (asthma)

 Effect of overexposure:  ingestion of even small amounts may cause naruea, vomiting, circulatory collapse, tachypnea, paralysis, convulsions, coma, greenish or smokey brown urine, necrosis of mouth and gastrointestinal tract, icterus, death from respiratory failure, sometimes form cardiac arrest.  Average fatal dose is 15 g but death form as little as one gram has been reported.  Fatal poisoning may also occur by skin absorption following application to large areas.

Antibiotics

Many antibiotics have been tried in root canals either as dressings or as the main filling inside the tooth. They only kill bacteria if they can reach the bacteria in suitable concentrations. This dosage is unachievable in the dentine tubules and accessory canals. Consequently, the low dosage applied to the bacteria stimulates a resistance in the bacteria to the antibiotic. This increases the already tragic number of bacteria that are resistant to antibiotics. The medical world struggles with this daily.

Exposure of bacteria to mercury produces both mercury and antibiotic resistance in many bacteria.

Antibiotics administered orally, may be helpful to reduce infection that has spread form the tooth. They will not however be able to do anything to the bugs inside your tooth as the blood supply has been removed and there is no way for antibiotics or the cells of your immune system to enter the tooth.

Root filling materials –

are permanently implanted into the tooth.  They are used to try to seal the canal and maintain the sterility that was not there in the first place.  They are placed in the tooth after it has stopped hurting, it no longer smells, and the dentist has run out of time/$ worthiness.  Dentistry still does not have any means by which to test the sterility of such a tooth and in other material presented here it is clear that such a dead tooth cannot be sterilised.

The American Association of Endodontists claims that teeth should be “sealed with a sterile, biocompatible material.” [i]

A quick reminder on the technique, is that once the tooth is considered ready to fill, a cement is spun down the root canal to within 1 mm of the end of the root.  This cement forms a sort of mortar that holds the bricks in place and supposedly seals any gaps between the bricks.  The bricks are made of rubbery points called gutta percha.  Often patients are told that the tooth is filled with a ‘natural’ material from rubber – this same gutta percha. 

Unfortunately, these little bricks are neither pure gutta percha and nor are they safe.  GP points may contain Gutta Percha, Zinc Oxide, Barium Sulphate, Titanium Oxide, Antioxidant, Iron Oxide (Colour agent), and Mastication Agents (a trade secret and not disclosed).

Dentistry has used gutta percha and no other material, to try to seal the canal in teeth for over 100 years. Any of the metals now included in GP points may cause severe autoimmune reactions. [ii]  If you happen to be one of those people who are sensitive or allergic to latex, then you should know that you may also be sensitive to gutta percha, as it is derived from latex.  I guess it is just too bad if you are sensitive, you will get it implanted into your body anyway, because that is what dentistry teaches.  I have seen many patients in this situation.  Their health was fine till the root filling was completed.  They were even able to tolerate the sterilizing medicaments, but their latex sensitivity finally got them when the GP points were sealed into the tooth.  How is this possible if, as the dental profession claims, all of the implanted materials stay sealed in a tooth?  The answer is obvious!  ALL GP points show high levels of toxicity which is attributed to the leakage of Zinc ions (ZnO) into fluids. [iii]  Everything that is placed I a tooth will leak into the surrounding tissues and then the rest of the body.  This has been made patently clear by the American Association of Endodontists.  “Moreover, scientific evidence has demonstrated that the damage from paraformaldehyde-containing filling materials and sealers is not necessarily confined to tissues near the root canal. The active ingredients of these filling materials and sealers have been found to travel throughout the body and have been shown to infiltrate the blood, lymph nodes, adrenal glands, kidney, spleen, liver and brain.”  [iv]  

Many cements have been used by dentistry to try to seal the canal.  None work.  Many are on the market, and it is the decision of the dentist as to which material will be used, like the decision as to which material to use to try to sterilise the tooth.  This decision also has NOTHING to do with any scientific support for its efficacy.  It is a decision based on supposition, cost, and ease of use, as well as how pretty the dental sales representative is. (no joke).

Zinc Oxide and Euginol (a derivative of oil of cloves) is the traditional root filling cement.  It has been around for decades. The extended use of this material is not an indication that it is safe.  Zinc Oxide root filling cements release zinc, high levels of which are found in distant organs – liver, kidney, uterus, and brain.  AH26 induced changes in calcium levels in these organs[v]

All root filling cements are cytotoxic – they kill cells.[vi],[vii],[viii],[ix],[x],[xi],[xii],[xiii],[xiv],[xv],[xvi],[xvii],[xviii],[xix],[xx],[xxi],[xxii],[xxiii]

Many Root filling cements are Mutagenic – they cause cancer – as published in the Journal of Endodontics in 2000. They cause changes in DNA which   “could lead to birth defects or malignant transformation of the tissue” [xxiv]

Many root filling cements are also neurotoxic. This means that they damage nerve tissue.  In several studies the materials tested blocked nerve transmission either partially or totally and in some cases the effect was irreversible. [xxv],[xxvi]

“The neurotoxic effects of the root canal filling materials- Endomethasone, N2 Universal, Traitment SPAD, Sealapex, and Calciobiotic Root Canal Sealer (CRCS)-were investigated on isolated rat sciatic nerves after local application.”

“Inhibitory effects of root filling materials on the conduction of action potentials evoked in rat phrenic nerves were evaluated in vitro. Endomethasone and N2 Normal completely and irreversibly inhibited conductance; ProcoSol caused complete but reversible inhibition; Kloroperka N-O caused total inhibition which was sometimes reversed; and AH26 and Diaket showed partial inhibition which was partially reversible.”

A SHORT word on Trigeminal Neuralgia

All materials placed in the tooth will travel throughout the body.  Some are transported along nerve fibres directly back to the brain.  (Retrograde Axonal Transport).  The nerves that innervate the teeth, jaws, gums, and lips derive form one cranial nerve.  This is called the Trigeminal Nerve.  It arises from a major structure in the brain called the Trigeminal Ganglion.  All materials placed in the tooth will easily travel to this major area of the brain.   

Is it a wonder that the Trigeminal Nerve is often affected by these toxins?  Irritation of this nerve may produce paresthesia, neuralgia and severe pains including Trigeminal Neuralgia. 

Trigeminal Neuralgia is not just a big name – it represents pain which is so intense that people have been known to commit suicide. [i],[ii]

The accepted treatment of Trigeminal Neuralgia totally ignores the wealth of published literature, which associates this disaster with both dead root treated teeth and also cavitations in the jaw bone. The dental profession simply denies this relationship and thus both the diagnosis and treatment are wrong.  Most patients are placed on antidepressants.  If this does not work (is it really a surprise?), they are advised to have brain surgery to section the trigeminal nerve from the base of the brain.  When this still does not work, the patient is referred to a psychiatrist.  These days the pain clinics in some of Sydney’s largest hospitals will not see a patient unless they first have a consultation with a psychologist!

With just a little integrity and acceptance of the published literature, many patients could be spared this outrageous abuse.  Would you prefer to have a dead tooth removed, or a hole in the jawbone cleaned, or to undergo brain surgery.  There is a wealth of literature, much of it published in the dental journals, which support the position that dead teeth and cavitations, are the main causes of trigeminal neuralgia. [iii],[iv],[v],[vi],[vii],[viii],[ix],[x],[xi],[xii],[xiii],[xiv],[xv],[xvi],[xvii],[xviii],[xix],[xx],[xxi],[xxii],[xxiii],[xxiv],[xxv],

From the Manufacturers

Most products which are to be used inside or on the body are usually accompanied by a written description which must be lodged with the Food and Drug Administration in America and the Therapeutic Goods Administration in Australia.  They must be publicly available on demand. 

They are called ‘Material Safety Data Sheets”   (If you search the net for “MSDS + product name”  you will find the full articles.) These materials are placed inside the tooth & left there.  These compounds are supposedly “sealed” into the tooth.  The problem is that they do not stay there. Everything that is placed in a tooth will spread throughout the body. In fact dentistry has never been able to find a way to ‘SEAL’ a root canal.  They will leak from the tooth slowly all of the time – 24hours/day.  The same is true for their Decomposition Products.

All materials which are placed in a tooth will spread throughout the body via the blood and the lymph, and also will be transported back to the brain along nerve fibres! Surely this information is critical to making an informed decision about the treatment to be embarked upon. I would like to know if a poison were to be placed in my body. I would expect that most people would want to know if a poison were to be placed in their body.

Gutta Percha Points

are the “Bricks” that are placed in the canal to try to seal it.  They are inserted after the cement is spun into the canal. 
Patients are usually NOT informed that they are Latex based.  If you have a latex allergy you may have serious consequences to your health from having these inserted into your tooth.

[v] In 1995, Economedes[v]  studied four different root filling cements.  They are amongst the most popular used at present – AH-26, Roth 811, CRCS, Sealapex   all caused mild to severe tissue irritation; 

Roth 811, CRCS  induced zinc redistribution to different organs (liver, kidney, uterus, brain;   

AH-26 (induced changes in Ca content in some organs).  Economedes  showed that zinc was distributed from root canals filled with CRCS and Roth 811. High levels were found in the brain, kidney, liver and uterus.
