Dr. Pirjo Pärnänen, inventor of fermented lingonberry mouthwash

Pirjo Pärnänen (Associate Professor in Oral Microbiology, DMD, PhD) has conducted laboratory studies of fermented lingonberry juice for 15 years, as well as four clinical studies.

 

Results of studies are stunning

Laboratory and clinical studies have shown a reduction in dental plaque and bleeding of the gums, and additionally antimicrobial, anti-inflammatory, anti-cancerous, and antioxidant properties. Caries-related Streptococcus mutans and candidosis- related Candida levels are reduced as well as periodontal disease- related pathogen levels. Levels of lactobacilli on the other hand are increased, which is thought to be a beneficial probiotic effect balancing the oral microbiota.
