Oral Health Test
Oral Health Test
Your mouth is home to billions of bacteria, some of which protect your teeth and gums, while others can contribute to cavities, gum disease, and bad breath. But did you know your oral health is also linked to heart disease, inflammation, and immune function?
Our at-home oral microbiome test uses a non-invasive saliva sample to deliver in-depth insights into your oral health. Through shotgun metagenomic sequencing, we analyse the full spectrum of microbial species in your oral cavity—identifying both commensal and pathogenic bacteria. Your personalised report provides clinically relevant data and evidence-based recommendations aimed at supporting periodontal health, preventing dysbiosis, and understanding the oral-systemic health connection.

Your Mouth Holds the Clues to Your Overall Health
Understanding your oral health through microbiome testing is vital, as the mouth acts as a gateway to the rest of the body.
An imbalance in oral bacteria has been linked not only to common dental issues such as tooth decay, gum disease, and bad breath, but also to wider systemic conditions including cardiovascular disease, diabetes, and complications during pregnancy.
By analysing the composition of your oral microbiome, this test provides early insights into potential health risks, supports targeted preventive care, and empowers you to make informed decisions for long-term oral and overall wellbeing.

Who Is This Test For?
Individuals with ongoing oral health concerns — such as cavities, gum inflammation, halitosis, or tooth sensitivity.
Patients with chronic conditions — where oral health may play a role in systemic inflammation or disease progression.
Individuals preparing for dental procedures — seeking a deeper understanding of their oral microbiome prior to treatment.
Those interested in preventive health — aiming to identify microbiome imbalances before symptoms arise.
Researchers or healthcare professionals — looking for comprehensive, microbiome-based insights to support clinical decisions.
Scope of Anaylsis: Oral Health Test

Microbial Composition
What we measure:
We analyse the relative abundance of key bacterial phyla in your mouth and compare them with healthy reference ranges. This includes:
– Often involved in energy metabolism and includes beneficial species like Streptococcus.
– Play a role in breaking down complex molecules, but some species may be linked to inflammation.
– A diverse group that includes both harmless and potentially pathogenic bacteria.
– Important for oral health; includes Actinomyces, known for plaque formation.
– Associated with periodontal health and inflammation control.
Microbial Richness, Diversity & Evenness
What we measure:
These indices give a picture of how balanced and resilient your oral microbiome is.
– The total number of different bacterial species detected in your sample. A higher richness is typically associated with better immune support and oral resilience.
– Measures both the number and abundance of bacterial species. Greater diversity supports stability and resistance to disease.
– Assesses how evenly your bacteria are distributed. A balanced community helps prevent any single harmful species from dominating.
Oral Health Risk Indicators
What we screen for:
We evaluate the presence of microbial genera and species associated with common oral health conditions:
1. Gingivitis Risk
- Bacteria measured include:
- Peptostreptococcus (increased level may raise risk)
- Treponema denticola
- Fusobacterium nucleatum
- Protective species like Streptococcus sanguinis and Actinomyces
2. Periodontitis Risk
Key bacteria include:
- Porphyromonas gingivalis
- Tannerella forsythia
- Aggregatibacter actinomycetemcomitans
- Dialister invisus and Treponema denticola
3. Dental Caries (Cavities)
Species analysed:
- Streptococcus mutans
- Streptococcus sobrinus
- Selenomonas spp.
- Scardovia wiggsiae
- Protective species like Streptococcus gordonii and Streptococcus sanguinis
4. Halitosis (Bad Breath)
Indicators include:
- Solobacterium moorei (increased)
- Treponema denticolaFusobacterium nucleatum
Systemic Health Correlations
What we explore:
Your oral microbiome may offer early clues about other health risks.
1. Type 2 Diabetes
Presence of bacteria like:
- Treponema denticola (linked to increased risk)
- Actinomyces and Veillonella (potentially protective)
2. Hypertension
Measured species include:
- Veillonella, Prevotella, and Streptococcus
- Haemophilus and Leptotrichia (nitrate-reducing, potentially protective)
3. Rheumatoid Arthritis
Associated with:
- Porphyromonas gingivalis
- Alloprevotella tannerae
- Prevotella and Veillonella (increased)
4. Inflammatory Bowel Disease (IBD)
Indicators include:
- Fusobacterium, Campylobacter, and Haemophilus
- Streptococcus and Bacteroides (potentially protective)
5. Mental Health Links
Includes correlations with:
- Mitsuokella, Veillonella, Neisseria (increased in depressive patterns)
Associations with mood regulation and immune modulation.
6. Chronic Respiratory Health (COPD & Inflammation)
Bacteria analysed:
- Haemophilus, Catonella, Moraxella
- Protective genera like Veillonella and Prevotella
