About The Mouth Biome

Type "oral probiotic review" into a search bar and the first page fills with manufacturer landing pages, affiliate roundups quoting those same manufacturers, and a forum thread where three strangers argue past each other. None of that comes from someone who actually used the product for a month and wrote down what happened.

This site closes that gap. The Mouth Biome runs oral probiotics and related products through the same routine every time: buy it at retail price, use it for at least 30 days, log what changes week to week, then check what actually happened against what the label promised. When the two don't match, the review says so, whichever direction the mismatch runs.

The underlying science rewards a closer look than most marketing copy gives it. Alcohol-based mouthwash isn't selective. It kills beneficial bacteria right alongside the harmful strains it's marketed to target. Certain strains, like S. salivarius K12 and M18, have trial data behind them that plenty of competing strains simply don't. Xylitol does something specific at the cellular level that has nothing to do with being "sugar-free." Figuring out where a supplement label's claims and the cited research actually diverge is part of the job here, article by article.

David Chen runs this from a home office in South Austin, seven years into more product testing than he probably imagined that first year. None of it amounts to professional medical advice, dental or otherwise; it's testing notes and reading notes from one person willing to show the raw numbers. How this particular habit started lives on the author page.
