Dr Andrew Knudson Research – The Science Behind ProvaDent

ProvaDent is not a randomly assembled supplement — it reflects Dr. Andrew Knudson’s structured research into oral microbiome science and its application to chronic dental disease. Here is the background on his research journey.

The Clinical Observation That Started the Research

Dr. Knudson’s interest in oral probiotics began with a clinical observation: patients with excellent oral hygiene habits continued to develop gum disease at rates that mechanical cleaning alone could not explain. This pattern suggested that something in the oral environment — rather than the cleaning behavior — was the primary determinant of disease susceptibility.

The Microbiome Literature Review

Dr. Knudson conducted a systematic review of the emerging oral microbiome research, which demonstrated that: specific bacterial compositions are associated with health versus disease states; the ratio of beneficial to harmful bacteria is more predictive of gum disease than bacterial total counts; and probiotic supplementation can meaningfully shift the oral microbiome composition in a favorable direction.

The Ingredient Selection Process

Based on his literature review, Dr. Knudson selected probiotic strains with specific documented activity in the oral environment — not generic gut probiotic strains. He supplemented these with minerals, vitamins, and botanical antioxidants based on their documented roles in gum tissue health and tooth mineral density.

The Protocol Development

Dr. Knudson’s research indicated that delivery format and timing matter for oral probiotics. Unlike gut probiotics where the delivery vehicle primarily affects survival to the gut, oral probiotics need to be released in and remain in the oral cavity. This influenced the ProvaDent format and the once-daily morning protocol recommendation.

The Ongoing Research Commitment

Dr. Knudson continues to monitor the oral microbiome research literature and plans ProvaDent formula updates based on emerging clinical evidence. This commitment to evidence-based formulation is a meaningful differentiator from supplement companies that create a formula once and never revisit it as science advances.
