Dentist and researcher Pirjo Pärnänen discovered that when lingonberry juice is fermented, its natural sugars disappear but its beneficial compounds remain. The result: a sugar-free rinse that fights the microbes linked to gum disease and tooth decay.
Clinical studies show that fermented lingonberry products can reduce inflammation, ease dry mouth and support good oral hygiene. Pärnänen’s research and the resulting products indicate how Finnish nature continues to inspire science and sustainable health innovations.
