Bristle (Bristle Health) is a consumer health company that makes the world's first at-home oral microbiome saliva test, helping people measure, understand, and improve their oral health. Customers order a mail-in saliva collection kit, and Bristle sequences the oral microbiome to report on bacteria associated with cavities, gum disease, and bad breath, then pairs the results with guidance and a line of targeted oral-care products including probiotics. Bristle also works with dental professionals who offer microbiome testing to their patients. The company sells direct to consumers through a Shopify-hosted storefront at bristlehealth.com and is backed by Initialized Capital. There is no first-party public developer API; this profile captures Bristle's public web, commercial, and security surface for the API Evangelist network.
