Oral Microbiome Test
Map your entire oral microbiome with 22+ biomarkers across periodontal pathogens, opportunistic bacteria, Candida, and protective flora — with salivary pH and clinical commentary on every finding.
Is this test right for you?
The oral microbiome is the gateway to the entire body. This test is designed for anyone experiencing dental, digestive, or systemic symptoms linked to what is growing in your mouth. Tap the ones that apply to you.
Chronic bad breath that mouthwash cannot fix is driven by anaerobic bacteria — particularly Fusobacterium, Prevotella, and Treponema denticola — producing volatile sulphur compounds. This test identifies and quantifies the exact organisms responsible so treatment goes beyond masking the smell.
Gums that bleed during brushing or are pulling away from the teeth signal periodontal disease driven by pathogens like Porphyromonas gingivalis, Treponema denticola, and Tannerella forsythia. This test detects all three — the ‘red complex’ bacteria most strongly linked to gum tissue destruction.
If you keep getting cavities despite good hygiene, the cause is likely elevated Streptococcus mutans — the primary driver of dental decay. This test quantifies your S. mutans levels alongside oral pH, both key predictors of caries risk that a standard dental check does not measure.
White patches on the tongue or cheeks, a burning sensation, or loss of taste indicate oral candidiasis. This test quantifies Candida albicans and other Candida species alongside Lactobacillus — the protective bacteria that normally keep fungal growth in check.
The mouth is the beginning of the digestive tract. Oral pathogens like Fusobacterium and Prevotella are swallowed continuously and seed the stomach and gut, contributing to reflux, GORD, and downstream GI inflammation. Testing the oral microbiome reveals whether your mouth is a source of ongoing digestive disruption.
Research shows oral bacteria that migrate to the gut can disrupt the intestinal microbiome, trigger inflammation, and worsen conditions like IBS and SIBO. If you have persistent gut symptoms alongside poor dental health, your oral microbiome may be the upstream driver your gut test cannot see.
Chronic throat infections can be driven by opportunistic oral bacteria like Fusobacterium nucleatum, Streptococcus mutans, or Pseudomonas aeruginosa colonising the throat and tonsils. This test maps the organisms in your oral cavity that may be seeding these recurring infections.
Periodontal pathogens — particularly P. gingivalis and Treponema denticola — enter the bloodstream through inflamed gum tissue and have been directly linked to atherosclerosis, endocarditis, and increased cardiovascular risk. This test screens for the specific organisms implicated in heart disease.
P. gingivalis has been found in the brains of Alzheimer’s patients and its toxic enzymes (gingipains) are now a leading research target in neurodegeneration. This test quantifies P. gingivalis and other pathogens linked to systemic inflammation that may contribute to cognitive decline over time.
Elevated levels of periodontal pathogens — especially Treponema denticola and P. gingivalis — are associated with preterm birth, low birth weight, and adverse pregnancy outcomes. This test identifies these organisms before or during pregnancy so they can be addressed proactively.
Dental plaque serves as a reservoir for respiratory pathogens like Pseudomonas aeruginosa and Acinetobacter. These organisms are aspirated from the mouth into the lungs, increasing the risk of pneumonia and chronic respiratory illness — particularly in older adults or immunocompromised individuals.
Oral bacteria that enter the bloodstream through damaged gum tissue can trigger systemic inflammatory responses linked to rheumatoid arthritis, IBD, and other autoimmune conditions. This test maps the specific pathogens known to drive extra-oral inflammation.

What's inside your report
Your oral microbiome report maps 22+ biomarkers — quantifying pathogenic bacteria, opportunistic organisms, Candida species, and protective flora with reference ranges and clinical interpretation.
| Test | Result | Flag | Reference |
|---|---|---|---|
| pH | 6.4 | L | (6.7–7.3) |
A low oral pH increases risk of dental decay, halitosis, and periodontitis. May indicate acidemia requiring further investigation.
| Organism | Result | Flag | Reference |
|---|---|---|---|
| Treponema denticola | 2.20 | H | (<2.00) ×10⁴ |
| Pseudomonas aeruginosa | 1.15 | H | (<1.00) ×10⁶ |
| Acinetobacter species | 2.20 | H | (<1.00) ×10⁴ |
| A. actinomycetemcomitans | <DL | (<1.00) | |
| Porphyromonas gingivalis | <DL | (<4.00) | |

| Species | Result | Flag | Reference |
|---|---|---|---|
| Candida albicans | 3.30 | H | (<1.00) ×10⁶ |
| Candida species | <DL | (<1.00) |
Elevated Candida albicans may indicate poor oral hygiene or high carbohydrate intake. Associated with increased risk of dental caries and oral thrush.
| Organism | Result | Flag | Reference |
|---|---|---|---|
| Streptococcus salivarius | 8.00 | OK | (>5.00) ×10⁷ |
| Lactobacillus species | 0.37 | L | (>1.00) ×10⁵ |
Low Lactobacillus species increases risk of infections and dental conditions. Probiotic supplementation may help restore levels.

It identifies and quantifies 22+ oral biomarkers including the specific bacteria linked to gum disease, cavities, bad breath, and systemic inflammation.
Your dentist examines what's visible — this test identifies the invisible bacterial species causing your symptoms, many of which are undetectable by visual examination alone.
You simply provide a saliva sample first thing in the morning before eating or brushing — it takes about two minutes.
Results are typically ready within 7–10 business days from when the lab receives your sample.
We often recommend pairing with the Gut Microbiome Test because oral pathogens like F. nucleatum and P. gingivalis frequently migrate downstream and disrupt the gut.
Yes — organisms like P. gingivalis are linked to Alzheimer's disease and T. denticola to cardiovascular disease, often long before oral symptoms appear.
Your report is a formal NATA-accredited pathology document that any dentist or GP can use to guide treatment decisions.
