FAQ'S
What does the Bristle test look for?
Bristle profiles your complete oral microbiome - the makeup of 100+ bacteria and fungi species in your mouth. Some of these species are beneficial to our health, while others are harmful and can cause conditions like halitosis, tooth decay, gum inflammation, and more. By analyzing the identity and relative abundance of bacteria in your saliva, Bristle detects the root cause of oral symptoms and connections to other chronic conditions. We also provide scientifically-backed product, diet, and lifestyle recommendations based on your unique oral microbiome.
How do I collect my sample?
Our test uses a small sample of your saliva. To provide your sample, you spit into a small tube containing a clear liquid solution that stabilizes your saliva. You mail back the tube to Bristle's laboratory using the prepaid envelope provided and results are returned online. Detailed step-by-step instructions of the sample collection process are included in each test kit and also available through your account dashboard after registering your kit.
When will I receive my test?
Orders ship within 1-2 days from purchase, and shipping usually takes 3 - 5 business days for delivery. We will provide you with updates on your order by email.
How long does it take to get my results once I return my sample?
Results will be returned to you in 2 - 3 weeks from when you mail your sample back to our lab.
Can I share the results with my dentist or doctor?
Yes! You can easily share your results from inside your dashboard. We encourage you to discuss your results with your dental or health provider (or both!).
What will you do with my data?
Data privacy is a top priority for us and we will never sell your data. We give you choices to control how your personal information is used, stored, or shared. We will never share your data without your consent, and will only ever do so at your request or in the name of advancing the research on oral health, the oral microbiome, and developing more personalized and effective treatments.
