“Frustrated with nothing to lose, I took the Bristle test."

I continually struggled with white tongue and oral thrush. I went through rounds of antibiotics, only to have the issue return. Finally, with the help of Bristle, I've been able to get to the root cause and get relief. No more issues, antibiotics, or doctors visits. Thank you, This means the world to me.

“If you make one investment in your health this entire year, let this be it. The mouth is the gateway to your body and oral bacteria have been associated with a higher risk for systemic conditions including Alzheimer’s, diabetes, cardiovascular disease, and poor pregnancy outcomes.

You can’t be healthy without a healthy mouth. And what you don’t measure, you cannot manage.”
