5,000+ people trust Bristle with their oral health

  • "My teeth are no longer developing plaque, my tongue is cleared up and has stayed clear, healthy and pink along with my gums AND my breath is fresh AF. Thank you! I’ve tried like five of the other top rated brands and did find one I ended up using for almost a year but this one by Bristle is the BEST! They took notes and combined the best of all the others. It’s affordable, mild mint flavor, and very affective."


  • I found Bristle while taking steps to fix some recurring gut issues, I wasn't aware of how connected your mouth flora and gut flora are until I began following the Bristle regiment and now my overall digestive and oral health are better than I even thought possible. 


  • So nice to get this deep healing level of help and advice and guidance . Their wisdom is so helpful and everyone is so efficient.


  • I need to get to the bottom of my halitosis and this is the only company that seems to be using science to fix it for good

“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.”
