Indeed we do! We have an oral microbiome test you can find here: https://www.bristlehealth.com/pages/products

and our first probiotic here: https://www.bristlehealth.com/pages/probiotic

All the species in the probiotic have been clinically studied with evidence that supports improvement in the oral microbiome and reduction of oral disease. Although, for transparency, the mechanism of action of some of the probiotics is still unclear, and we're working on figuring that out to improve oral probiotics and products in the future.
