10 Best Bristle Alternatives & Competitors (2026)

Viome provides full-body microbiome testing via stool and oral samples with AI-generated food and supplement advice. Its oral module is less granular than Bristle on cavity- and gum-specific species and pricing starts higher at roughly $299 per kit. Users seeking only oral health insights often find Bristle's focused report and dentist-approved action plan more direct and affordable.

LetsGetChecked provides mail-in tests for hormones, vitamins and STDs. It has no oral microbiome offering, so users needing bacteria-level insights into gum inflammation must turn to Bristle for the relevant data and recommendations.

OralDNA offers clinician-ordered saliva tests that detect periodontal pathogens. It requires a dental provider visit and does not ship direct-to-consumer kits like Bristle. Results are clinical but lack the consumer-friendly custom probiotic and diet plans Bristle supplies at a lower out-of-pocket cost.

Function Health offers comprehensive blood panels and some microbiome add-ons. It does not specialize in oral bacteria or supply the targeted gum-inflammation protocols that make Bristle the more precise choice for chronic bad breath sufferers.

Thorne sells microbiome testing and probiotic supplements with practitioner oversight. Its gut-centric reports give limited oral health detail compared with Bristle's species-level scoring for bad breath and decay, and the price point is higher for ongoing supplement bundles.

Atlas Biomed delivers microbiome and genetic reports focused on nutrition and disease risk. Its oral sampling is minimal and lacks Bristle's dentistry-specific scoring or 30-day improvement tracking for bad breath and gum issues.

Perio Protect sells prescription trays and gels for gum disease treatment through dental offices. It addresses symptoms without testing which bacteria are present, unlike Bristle's diagnostic saliva analysis that guides precise probiotic use.

Boka markets nano-hydroxyapatite toothpaste and oral probiotics. While it offers products Bristle may recommend, it provides no testing service to identify which bacteria need targeting, making it a supplement rather than a diagnostic alternative.

MyMicrobiome analyzes skin and vaginal microbiomes with some oral options. Its reports are less actionable for dental concerns and lack the HSA/FSA eligibility and dentist-reviewed care plans that distinguish Bristle.
