Dentists Use Chlorine Dioxide – Just Don’t Swallow

Published on April 18, 2022

Chlorine dioxide (ClO2), a potent biocide, has been used to disinfect municipal water for many years. Now dentists are using it to great effect to control conditions in the oral cavity. Chlorine dioxide is openly recommended by medical science and used for wound irrigation and for treating oral health issues. No substance would ever be used by hospitals and dentists for these purposes if it, in fact, were toxic.

CLO2 is probably the most extensively tested disinfectant in history. It is a safe and effective biocide. It has been used for eliminating pathogens in water and is excellent for attacking biofilms. That is why it is used in commercial water cooling towers. It works so well that pharmaceutical companies had to convince governments worldwide to make it illegal to swallow because it would put them out of business. It is unlawful to promote it as a medicine even though dentists know it is and use it to help their patients.

Because of this biofilm control property, dentists love it because it gets the teeth squeaky clean as the film pellicle that forms on teeth (responsible for plaque adherence) breaks down. Its effectiveness for whitening and freshening does not come from magic but from fundamental chemistry. But even more importantly, chlorine dioxide mouthwash used over a 7-day period is effective in reducing plaque, tongue coating accumulation, and the counts of Fusobacterium nucleatum in saliva. As one would expect, it is also effective at eliminating bad breath.

Chlorine dioxide is used to disinfect drinking water around the world and is approved for use by the Environmental Protection Agency (EPA) and included in the World Health Organization’s (WHO) Guidelines for Drinking-water Quality. The U.S. Food and Drug Administration (FDA) also has approved the use of chlorine dioxide in specific food applications and over-the-counter and prescription drugs. Chlorine dioxide helps destroy bacteria, viruses, fungus and some types of parasites that can make people sick, such as Cryptosporidium parvum and Giardia lamblia.

Chlorine dioxide can be used in mouthwashes and dentistry products as an oxidizing biocide compound. It is legal to allow it into the mouth, but God forbid you to swallow it, for then the FDA will call out their SWAT teams and bust down your door. Perhaps they will have to put a camera in every bathroom to make sure you don’t swallow.

Given that chlorine dioxide is routinely added to drinking water, sprayed on food, used in toothpaste and mouthwash, and is an approved ingredient in over-the-counter and prescription drugs, the media-generated hysteria that chlorine dioxide is “toxic bleach” is easily refuted.

What it does in the oral cavity, it will do to the entire body if you swallow. Use of CDS (chlorine dioxide) as a mouthwash along with DSMO is widely used in dentistry, and some companies have created CDS mouthwash products.

Dentists Love Chlorine Dioxide

DioxiBrite’s Active Chlorine Dioxide toothpaste incorporates qualities never found in toothpaste before. It outperforms all major brands because it uses chlorine dioxide.

  • Fast-acting: It kills all mouth bacteria in one minute
  • Remove stains and whitens teeth naturally
  • It kills germs that cause bad tastes and odors, immediately refreshing your breath.
  • Eliminates tartar & plaque buildup, the primary cause of tooth decay and gum disease.
  • Improves enamel giving you strong, healthy teeth.
  • Quickly permeates between tooth surfaces and gums, healing gingivitis
  • Deactivates bacteria, viruses, yeast, and spores; fewer germs in your mouth
  • It helps keep your toothbrush clean and germ-free.
  • It does not sensitize the teeth and has an invigorating natural flavor.

Dr. Syed Ahmed Raheel writes, “Aqueous solutions of chlorine dioxide (ClO2) have been effectively used as an antiviral preventive protocol in mouthwash for a long time. This aqueous ClO2 can inactivate all types of pathogens in the oral cavity. Noss et al. (1986) showed the actions of ClO2 on viral capsid proteins, namely cysteine, tyrosine, and tryptophan, as they readily reacted with ClO2. Ogata (2007) listed the antimicrobial activity of ClO2 mainly due to protein denaturation followed by oxidative modification of tyrosine and tryptophan.” Gargling with iodine has also been more than helpful in containing COVID  and other pathogens in the oral cavity.

Interestingly enough, SARS_CoV-2 sports spike proteins containing residues of tyrosine, tryptophan, and cysteine. Therefore, Dr. Raheel thinks that using chlorine dioxide in the mouth can prevent COVID infections (and that would be legal), but it must be swallowed for treatment once infected. (Don’t do that unless you want to clear the body of COVID quickly.)

Products with stabilized chlorine dioxide is helpful for cancer patients. They do not contain alcohol, do not cause staining or alter the taste, and can be used long-term without a prescription. However, products containing chlorine dioxide already mixed in a bottle lose effectiveness after being open for two weeks and no longer have bactericidal benefits. A two-part system such as OraCare, where ingredients are combined and activated for 30 seconds before rinsing, solves that problem.

OraCare rinse mitigates some of cancer treatment’s most common oral side effects. Almost all patients who undergo chemotherapy and radiation experience the adverse oral side effects of treatment, such as dry mouth, increased decay, mouth sores, and fungal infections.

OraCare utilizes activated chlorine dioxide and xylitol, which have properties that extend to various uses throughout the practice. It eliminates bacteria, viruses, and fungi, making it an ideal pre-rinse. It is commonly recommended for home care, tissue management, bad breath, gingivitis, periodontal disease, decay reduction, dry mouth, mouth sores, and fungal infections. Coincidentally, these are some of the most common oral side effects of cancer treatment.

“OraCare was invented for general hygiene patients as a better alternative to chlorhexidine rinses. But almost immediately, we started hearing from cancer patients telling us that it provides incredible relief from their uncomfortable side effects. We started the OraCare Cares Program specifically to help more of these patients,” said Dr. Robert Martino, OraCare CEO.

Catherine N. from Quebec says:

I am currently undergoing chemotherapy for breast cancer. Some of the side effects of the chemo are mouth sores, dry mouth, and a metallic taste that never seems to subside despite several brushings per day. The only thing that gives me some relief from all these symptoms is OraCare. It cured two mouth sores in a day, and it helps alleviate dry mouth each time I have chemo.

In the past, both hydrogen peroxide and chlorhexidine rinses have been used. Neither is recommended now. Hydrogen peroxide is not recommended as it may delay wound healing, promote emesis, cause demineralization, promote fungal growth, and contribute to dry mouth, thirst, and discomfort. Chlorhexidine is not recommended as it may interfere with healing, alter oral flora, promote bacterial (pseudomonas) growth, has an unpleasant taste and results in taste distortion, stains teeth and cosmetic restorations, and contains alcohol. Chlorhexidine is not effective in the presence of blood or toothpaste, and nystatin reduces its effectiveness.

Part Two – Doctors Should Prescribe Chlorine Dioxide For Oral Care

Doctors should be especially interested in recommending chlorine dioxide to all their patients to control the flora in their mouths, importantly to eliminate gingivitis, and thus overall inflammation and increased rates of heart disease.  (Coming Soon)

Make It Yourself Testimony

“I have developed a new Protocol for oral hygiene called Protocol-MT&T. It combines CLO2 and Baking Soda to create a slightly alkaline 50 ppm solution which I feel is just right to be used as a mouthwash, as a teeth brushing solution, and as a throat gargle twice a day for as many years as you like. A side benefit of using it twice a day, week after week, month after month, etc. though, is that I believe using it in this way will also act as a prophylactic against all respiratory viruses, including Covid, and it may be what has helped me to stay Covid free the entire pandemic.”
