Why Test Your Saliva?

A dental exam shows what your teeth and gums look like today. A saliva test helps identify bacteria associated with gum disease and cavities, sometimes before you notice a problem.

Why Choose At-Home Salivary Testing?

Salivary testing is a non-invasive diagnostic tool that reveals what visual dental exams miss. By analyzing your saliva, our dental saliva test kits detect early markers of oral bacteria, periodontal risks, and systemic health indicators before symptoms appear.

Comprehensive Oral Diagnostics: Identify high-risk saliva bacteria before tooth decay or gum irritation develops.

Simple At-Home Collection: Collect your sample in 2 minutes with zero pain or hassle.

Actionable Results: Get personalized insights into your oral microbiome balance and targeted care recommendations.

Why Saliva?

Your mouth is the gateway to your body. Early detection of systemic issues through oral biomarkers supports long-term health and prevention.

Choose OralDNA if your main concern is your gums, teeth or breath. Choose Viome if you want a broader view of your gut and whole-body health. You can also ask us to help you choose.

OralDNA: 7–10 business days after the lab receives your sample. Viome: 2–3 weeks.

Coverage varies by insurance provider and plan. We provide detailed receipts that you can submit for potential reimbursement. Many HSA and FSA accounts cover these tests.

Yes. OralDNA focuses on your mouth and Viome on your wider health, so the results complement each other.

Both tests are processed in CLIA-certified laboratories. [CONFIRM for both.] Results show which bacteria are present and at what levels. Your provider uses them alongside an exam, not instead of one.

OralDNA: don't eat, drink or brush for 30 minutes before you collect your sample. Viome: follow the instructions in your kit.

Your report appears in your dashboard. A provider reviews it with you and suggests a treatment or prevention plan. Retest in 6–12 months to check progress.

No. OralDNA checks for high-risk oral HPV types, which are linked to some throat and mouth cancers, but it doesn't diagnose or predict cancer. See a dentist for an oral cancer exam.

Specific bacteria like P. gingivalis can enter the bloodstream through the gums, causing systemic inflammation linked to heart disease. Saliva testing identifies these "red-complex" bacteria so you can take proactive action.

A dental saliva test (or salivary diagnostic test) analyzes salivary biomarkers and bacterial DNA to measure cavity risk, gum disease susceptibility, and overall oral microbiome health. You can order an at-home saliva testing kit directly online through Dentulu with prepaid return postage included.
