Discover how Finnish lingonberry innovation can boost oral health

A University of Helsinki dentist has found that the tart lingonberry – the cranberry’s wild cousin, abundant in Finnish forests – can help keep your mouth healthy.

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.
