Oral Probiotics Treat Oral Candida Infections

Candida yeast species such as Candida albicans can easily infect an oral cavity whose defenses have been weakened. Brushing with a strong toothpaste or gargling with an antiseptic mouthwash might help, but only a little.

Candida species of yeasts have also become stronger over the years, especially with our increasing use of antiseptics. Not only are most antiseptics geared towards bacteria (“septic” or “sepsis” typically refers to bacterial infection), but yeast microorganisms eventually learn to counteract antiseptic mouthwashes and dentifrices.

Many species of Candida yeasts normally live in our guts and oral cavities. But when other microorganism species are weakened, these yeast species can grow out of control. Furthermore, stronger species of Candida yeasts can also invade our bodies and infect us.

Hospitals and other primary care facilities have become increasingly concerned with Candida. Doctors have found these species can become not just disease-causing when they infect patients. There have been deaths brought on or exacerbated by Candida infections in some cases.

So what is the answer? As I explain in depth in my book on the topic, it is better to fight fire with fire.

That is, to use friendly microorganisms to fight the unfriendly pathogens such as candida for territory. In the case of oral candida, the territory we are talking about is the oral cavity. Yes, our oral cavity is full of microorganisms including bacteria and yeast. One study found over 700 species of microorganisms in the mouth.

Oral Candida versus Oral Probiotics

This strategy was tested by researchers from Denmark’s University of Copenhagen, along with doctors from Sweden’s Halland Hospital. The physicians conducted a study of 215 people between the ages of 60 and 102 years old. The patients were living in nursing homes and were considered as frail.

They also were selected because they had oral candida infections.

The clinical trial was double-blinded and placebo controlled. The patients were divided into two groups. One was given one lozenge twice a day that had two species of oral probiotic bacteria in it. The other group was given a placebo lozenge.

The therapy lasted three months – or twelve weeks to be precise. The oral probiotic species given were two different species of Lactobacillus reuteri.

Both groups were tested at the beginning of the trial and at the end of the twelve weeks. The test consisted of Candida counts along with dental plaque and inflammation of the gums – the presence of gingivitis.

Candida counts lower among the oral probiotics group

After the twelve weeks, the oral candida counts in the probiotic group were significantly lower in the oral probiotic group. Meanwhile, the placebo group’s oral candida counts remained unchanged. Thus, the probiotic group had significantly lower candida counts compared to the placebo group.

The researchers concluded:

“Thus, daily use of probiotic lozenges may reduce the prevalence of high oral Candida counts in frail elderly nursing homes residents.”

Further application

While elderly nursing home residents were the focus of this research, the application should also apply to practically anyone with oral candida. Candida species can infect virtually anyone at any time, especially when intakes of refined sugar are high.

This is because candida feed off of (or ferment) refined sugars. This can include fruits as well, because candida species feed on fructose along with sucrose.

Candida overgrowths can also occur following antibiotic treatment or antiseptic treatment. This can include dental treatments that apply antiseptics.

Oral infections of candida often indicate intestinal and genital infections of candida species. Probiotic strategies to eliminate those as well is supported by the research. Learn more about probiotics.
