More than 10 years ago, I was introduced to the Purebrush Antibacterial Toothbrush Purifier. After performing the research on the effectiveness of the System in killing disease-producing germs, I not only advocated the System to my patients, but I also became the Medical/Dental Director for Murdock Laboratories, maker of the Purebrush.

Over the years, a number of my patients, many of whom suffered from both dental and systemic chronic diseases, have benefited from the use of the Purebrush. I feel the Purebrush Antibacterial Toothbrush Purifier is one of the most effective devices available to prevent the re-infection and spread of disease-producing germs." 

Clinical studies confirm that harmful and even deadly microorganisms can incubate on common toothbrushes.

These clinical studies, conducted by Dr. Richard T. Glass, DDS, PhD, Professor of Pathology, Oklahoma State University, have encompassed testing of multiple types of bacteria, yeast and viruses that were found to not only
commonly cause oral and gum diseases of the mouth, but were also found to be significant causes of diseases affecting the entire human anatomy.

"Microorganisms are everywhere in our environment and thrive in cool dark places, just the type of places people store their toothbrushes," said Dr. Glass. "A pair of moist toothbrushes left side by side in a medicine cabinet provides an ideal breeding ground for germs and viruses. Cold and flu viruses, even the bacteria that cause gingivitis, can travel from brush to brush."

Dr. Glass has conclusively demonstrated a direct correlation between the state of a person's oral health and that person's general health and well being. According to these clinical studies, the toothbrush not only comes into direct contact with human host viruses and bacteria, but is also subject to contamination by all kinds of airborne microorganisms. The bathroom is by far the most infectious environment within the household.

It is typically high in humidity and is subject to a multitude of airborne microorganisms, for example, with each flush of the toilet. The individual is at serious risk of introducing these pathogenic microorganisms into their system via their toothbrush. Chemical treatments, dishwashing, boiling, autoclaving and even microwaving either does not kill large numbers and groups of microorganisms or renders the toothbrush completely unusable.

Clinical studies confirm the Purebrush Antibacterial Toothbrush Sterilizer has proven 99.9% effective in eliminating harmful bacteria and viruses found to incubate on common toothbrushes thus allowing people to use a germ-free toothbrush every time they brush. "This is the single greatest oral healthcare enhancement in the fight against microorganisms since the advent of antibiotics. The ability for a person to sterilize their toothbrush after each use and store it in a germ-free environment has tremendous health benefits. The advent of a home use tooth-brush sterilizer is not only a significant advancement in infection control for the typical household, but will significantly contribute to better overall health within the general population," noted Dr. Glass.

When you store your toothbrush in an unprotected environment, you expose your toothbrush to millions of airborne microorganisms. University studies have proven that the Purebrush System eliminates up to 99.9% of all yeast, molds, viruses, and illness causing bacteria that live and flourish on your toothbrush. With Purebrush, you can protect your family from illness caused by re-infection and cross-contamination. Simply place your toothbrush inside Purebrush and let the 100% safe UV light dry and disinfect each bristle so the only thing you'll be putting in your mouth is a pure brush.
