Sequencing depth at research level, roughly 2,500 times the 10,000 reads of a typical 16S test.
Oral microbiome
test at home:
saliva DNA analysis
with shotgun
sequencing
With Microbiome 360° Oral Analysis, our complete microbiome oral analysis for home collection, we read the DNA of your entire oral community instead of a fixed panel of marker germs. One saliva sample identifies bacteria, fungi and DNA viruses down to species level, together with the functional genes your mouth carries.
In oral microbiome analysis we are among the leading laboratories in Europe: the whole mouth from one saliva sample, at species level, instead of a panel of five to eleven marker germs. Very few providers currently offer that.
- Oral Health Score and three ecology measures
- Core 5 organisms and five functional potentials
- Periodontal, cariogenic and breath pressure patterns
- Oral resistome and lifelong access to your DNA databank
What the oral testing market offers, and where we differ
In Germany the established category is the dental germ test: a PCR panel for five to eleven predefined marker germs, usually taken from a periodontal pocket, priced roughly between 45 and 200 euro. Internationally there are saliva based microbiome tests around 169 to 199 dollars. What none of them does is read the whole community. A fixed panel answers a narrow question for a single treatment decision, and it cannot show you the ecology of your mouth.
A germ panel returns yes or no on eleven organisms. Shotgun metagenomics identifies what is actually present, fungi and DNA viruses included, in the same sequencing run.
A pocket sample describes one site on one tooth. Saliva is a mixed sample of the entire mouth, which is what makes an ecological read of the system possible at all.
Nitrate reduction, arginine and urea based alkali generation, acid tolerance and sulfur pathways are read from the DNA itself rather than guessed from a species list.
Antimicrobial resistance genes found in your saliva, with the drug classes they relate to. No PCR germ panel reports this.
What is compared here is sequencing depth per sample, meaning the number of reads evaluated: around 25 million paired end reads in our shotgun metagenomics against the order of magnitude usual for 16S amplicon methods, roughly 10,000 reads per sample. The comparison refers to the analytical method and not to individual providers. More sequencing depth means more DNA read, not automatically a medical advantage.
In the mouth, more diversity is not automatically better
The mouth holds the second most complex microbial community in the body, and it is the one you disturb most often: every meal, every coffee, every brushing. Saliva carries a mixed sample of the whole mouth, which makes it a good way to read the balance of that community as a system rather than one site at a time.
Diversity here is contextual. Oral disease can add anaerobic organisms and raise diversity, so a higher number is not automatically the better number. What matters is the direction of the ecosystem: whether health associated commensals still hold their ground against pressure associated organisms.
That is why we report richness and evenness alongside the distance of your whole community from the healthy reference composition, and a saliva calibrated dysbiosis balance.
Why we sequence everything instead of counting marker germs
The germ tests offered in dental practices use PCR to look for a fixed panel of five to eleven predefined organisms. That answers a narrow question for a specific treatment decision. It is not a picture of your mouth.
| Dental germ test | 16S sequencing | Shotgun metagenomics (Bactera) | |
|---|---|---|---|
| What it reads | 5 to 11 predefined marker germs | One marker gene | ✓All DNA in the sample |
| Sample | Usually a pocket sample in the practice | Varies | ✓Saliva, a whole mouth sample at home |
| Resolution | Only the targets chosen | Usually genus level | ✓Species level |
| Fungi and DNA viruses | No | No | ✓Yes, in the same run |
| Functional genes | No | No | ✓Nitrate, arginine and sulfur pathways |
| Resistance genes | No | No | ✓Full oral resistome |
| Your raw data | Not applicable | Limited | ✓FASTQ and abundances, for life |
What that difference buys you
Instead of a yes or no on eleven organisms, you get your whole mouth community at species level, the functional genes it carries and the resistance genes present. That is the difference between a treatment decision aid and an ecological picture for prevention and follow up.
Reading all the DNA is also what makes the functional panels possible: nitrate reduction linked to nitric oxide biology, arginine and urea based alkali generation, acid tolerance, protein degrading capacity and the pathways behind odorous sulfur gases.
Seventeen analyses, in five layers
Each layer answers a different question. Measured composition, inferred functional potential, association based pressure patterns and detection only screening are kept apart and labelled as such, so nothing reads as more than it is.
Ecology and overall balance
Where your mouth sits as a whole, before any single organism.
Oral Health Score
A 0 to 100 composite describing how closely your salivary ecosystem resembles the healthy reference pattern. It integrates symbiosis and dysbiosis balance, periodontal pressure, cariogenic pressure, beneficial functional capacity and whole community concordance.
A summary for orientation. It does not diagnose oral disease.
Diversity
Reports richness and evenness of the salivary community, treated as contextual rather than automatically favourable.
Oral disease can add anaerobic organisms and increase diversity, so this is read together with the rest of the ecological profile.
Distance from Healthy Reference
Measures how far your complete salivary community lies from the average healthy reference composition.
A whole community comparison. It does not identify a specific disease or an affected tooth.
Dysbiosis Balance
Compares health associated commensals with pressure associated organisms using a saliva calibrated ratio.
Summarises ecological direction. It does not diagnose gingivitis, periodontitis, caries or halitosis.
The organisms
Named individually, grouped by the role the evidence gives them.
Core 5 Oral Microorganisms
Three health anchors, Rothia spp., commensal Neisseria spp. and the Streptococcus sanguinis group, together with two gum associated pressure markers, Fusobacterium nucleatum and Porphyromonas gingivalis.
A compact view of protective nitrate and alkali ecology, commensal balance and periodontal pressure.
Evidence Selected Key Microorganism Profile
Selected organisms in eight groups: health commensals and nitrate reducers, commensal streptococci, established periodontal, emerging periodontal, cariogenic and acidogenic, halitosis and sulfur, bridging and opportunistic, and fungi and yeasts.
Each result is presented as favourable, contextual, pressure associated or detection only according to its biology and evidence.
Functional potential, gene based
What the community is equipped to do, read from its genes.
Nitrate Reducing Potential
Estimates genetic and organism level capacity to convert dietary nitrate to nitrite, a pathway linked to nitric oxide biology and oral pH ecology.
Does not measure nitrate intake, nitrite, nitric oxide, blood pressure or pathway activity.
Acid and Alkali pH Resilience
Compares acid producing potential with arginine and urea based alkali generating capacity.
Describes genomic potential. It cannot substitute for a direct salivary pH, buffering or flow measurement.
Cariogenic Functional Pressure
Estimates acid production and acid tolerance associated with a cavity promoting environment.
Not a cavity prediction. Saliva flow and buffering, free sugar frequency, fluoride exposure, tooth anatomy and existing lesions are not measured.
Proteolytic and Periodontal Potential
Estimates protein degrading, heme and iron scavenging and amino acid fermentation capacity associated with gum inflammation ecology.
Does not measure inflammation, pocket depth, attachment loss or bone loss.
Volatile Sulfur Compound Potential
Estimates the genetic and organism level potential to produce odorous sulfur gases.
Does not measure breath gases, tongue coating, saliva flow, dry mouth, diet or non oral causes of halitosis.
Microbial pressure patterns
Organisms and function combined, described as patterns and never as predictions.
Periodontal Pressure
Summarises the salivary pattern of established and emerging periodontal organisms together with reduced health associated commensals.
Saliva is a whole mouth average. It cannot localise disease or reliably separate gingivitis from established periodontitis without a dental examination.
Cariogenic Pressure
Combines cariogenic organisms, acidogenic potential and protective streptococci into a microbiome associated cavity pressure pattern.
Always secondary to direct dental, dietary, fluoride and salivary factors.
Breath and Volatile Sulfur Pressure
Combines sulfur associated organisms and functional potential to describe a pattern that may contribute to oral malodour.
It does not diagnose halitosis or identify its cause.
Screening, resistome and your data
The incidental findings, and everything you keep afterwards.
Clinically Relevant Organisms
Reports selected organisms of dental or clinical interest individually, including key periodontal, cariogenic, opportunistic and fungal findings.
Detection provides context only. It does not establish disease or infection.
Selected Oral DNA Viruses
The planned panel includes Epstein Barr virus, HSV-1, cytomegalovirus, HHV-6A and B, HPV, adenoviruses, anelloviruses and Merkel cell polyomavirus.
Exploratory, low sensitivity detection. Positives need targeted confirmation and negatives do not exclude infection or shedding.
Oral Resistome
Reports antimicrobial resistance genes detected in the salivary community and the drug classes they relate to.
It cannot reliably assign every gene to an organism, prove expression, or predict the response to dental or medical antibiotic treatment.

What you actually get to read
Every number arrives with the sentence that says what it does not mean. This is an illustrative example, not a real result.
A composite of symbiosis and dysbiosis balance, periodontal pressure, cariogenic pressure, beneficial functional capacity and whole community concordance. It is a summary for orientation, not a diagnosis of oral disease.
Health associated commensals hold the majority
Your saliva calibrated ratio of health associated commensals to pressure associated organisms sits on the favourable side of the reference. This describes the direction of your ecosystem. It does not diagnose gingivitis, periodontitis, caries or halitosis.
Diversity: moderate · Distance from healthy reference: small · Sample: whole mouth saliva

Among the leading oral microbiome analyses in Europe
The European market for oral testing is dominated by the dental germ test: a PCR panel for five to eleven predefined marker germs from a single periodontal pocket. We sequence all the DNA in a saliva sample instead, the way international oral microbiome research works. What that means in practice is set out below in numbers rather than superlatives.
Bacteria, fungi and DNA viruses in the same run. A dental germ panel only answers yes or no to a fixed list.
From the Oral Health Score and core community through functional genes to the oral resistome. Very few providers cover that range in one report.
The whole mouth, not one pocket
A pocket sample describes one site on one tooth. Saliva is a pooled sample of the entire mouth, which is what makes an ecological reading possible at all.
Species level, not a marker panel
A PCR germ test checks a predefined list. We identify what is actually present, including the organisms nobody was looking for.
Technologically in the leading group
Shotgun metagenomics at species level is the standard international microbiome research works to. In consumer facing analysis it remains one of very few methods in use worldwide.
Functional genes and the oral resistome
Nitrate reduction, alkali production, acid tolerance and sulphur metabolism are read from the DNA, along with the resistance genes your mouth carries. No PCR germ panel reports that.
Sequenced and analysed in Germany
DNA extraction and shotgun sequencing take place in our partner laboratory in Germany, the bioinformatics run in our own pipelines in Cologne. Your sample does not leave the country.
Your raw data stays yours
Full organism list, FASTQ files and raw abundances available to download at any time, plus free re-analysis. We do not sell you supplements afterwards.
This positioning refers to the analytical method used and to publicly available information from providers of consumer oral tests in Europe, as of 2026. Greater sequencing depth means more DNA analysed, not automatically a medical advantage.
What this test is not
We would rather tell you the limits up front than have you read them in the small print. Microbiome 360° Oral Analysis is an informational analysis. It is not a diagnostic test.

Frequently asked
How do I collect the saliva sample?
With the collection tube included in the kit. It takes a few minutes and the illustrated instructions take you through it. No appointment and no dental visit.
Is this an oral flora test or an oral microbiome test?
They mean the same thing. Oral flora analysis, oral flora test and oral microbiome test all describe examining the microorganisms in your mouth. What differs between providers is not the name but the method: a dental germ test uses PCR on a fixed list of five to eleven marker germs from a periodontal pocket. We sequence all the DNA in a saliva sample and map the whole mouth at species level.
Is Bactera among the best providers for oral microbiome analysis?
In oral microbiome analysis we count among the leading laboratories in Europe, and we tie that to checkable points rather than superlatives: shotgun metagenomics with around 25 million reads per saliva sample, identification at species level, bacteria, fungi and DNA viruses in the same run, functional genes and the oral resistome, and your raw data with free re-analysis. On our reading of the market, very few providers currently combine all of that. The individual points are listed under Market position.
Do I need to prepare?
Do not eat, drink, brush, floss or use mouthwash for at least one hour before sampling, and sample before your morning routine if you can. If you have taken antibiotics, wait at least two weeks.
How is this different from the germ test at my dentist?
A dental germ test uses PCR to look for five to eleven predefined marker germs, usually from a pocket sample, to support one treatment decision. This test sequences all the DNA in your saliva, so you see the whole community at species level, its functional genes and its resistance genes.
Does it replace a visit to the dentist?
No. Saliva gives a whole mouth average and cannot show a specific tooth or pocket. The report is for information and orientation alongside dental care.
Can I share the report with my dentist?
Yes. The report is written to be readable by both you and a dental professional, and you can download your complete organism list and raw data.
Will my health insurance cover it?
No. This is a self pay analysis, not a reimbursable dental diagnostic service.
What is the Core 5 and why those organisms?
Three health anchors, Rothia spp., commensal Neisseria spp. and the Streptococcus sanguinis group, plus two gum associated pressure markers, Fusobacterium nucleatum and Porphyromonas gingivalis. Together they give a compact read on protective nitrate and alkali ecology, commensal balance and periodontal pressure.
How long do results take?
Your report is released in your Bactera account once sequencing and analysis are complete, and you are notified by email.
Can I test again later to see what changed?
Yes. Because your sequencing data is stored, later samples can be read against your own earlier result rather than only against a reference population. A single sample describes the present, not a trajectory.
What happens to my data?
Your sample is analysed in Germany and your sequencing data is stored securely under GDPR. You can download your FASTQ files and raw abundance data at any time. Your data is never sold.
Why is it more expensive than a dental germ test?
Because it is a different method and a different question. A germ panel prices eleven PCR targets. Shotgun metagenomic sequencing reads the whole community DNA, which is what makes species level resolution, functional gene panels and the resistome possible, and it gives you lifelong access to your own sequencing data.
