A Revolution in Oral Health through Probiotic Research

Every story starts with a personal struggle. For Dr. Jong-Suk Oh, it was the frustration of facing recurring oral health issues despite doing everything right — brushing, flossing, even using mouthwash. At UCLA School of Dentistry, he realized that the answer couldn’t be found in conventional routines alone. Something deeper had to be uncovered.

His curiosity led him into the emerging world of the oral microbiome. There, he discovered that the balance of bacteria inside our mouths holds the key to true oral wellness — and that probiotics could be the breakthrough solution.

In 1997, Dr. Oh carried this vision back to South Korea, founding a research initiative at Chonnam National University’s Medical School. Together with his team, he began isolating and identifying unique probiotic strains that could naturally support oral health. Each discovery brought them closer to reimagining how we care for our mouths.

That journey continues today at Oraticx®. What began with one researcher’s search for answers has grown into a mission: to transform oral health through the power of probiotics, and to make lasting wellness part of everyday life.
