Bacterial DNA Testing and Oral Microbiome Assessment in Beverly Hills
What Is Bacterial DNA Testing?
Bacterial DNA testing, also called an oral microbiome assessment, is a simple, non invasive saliva or plaque test that identifies the exact species of bacteria living in your mouth. Rather than guessing which bacteria are driving your gum disease, decay, or inflammation, the test pinpoints them by name and measures how aggressive each one is.
We recommend bacterial DNA testing for patients with recurring gum disease, persistent inflammation, complex implant cases, autoimmune conditions, or anyone who wants a precision based approach to their oral health. Different bacteria require different treatments, and treating the wrong bacteria is why some patients never fully heal.
Patients typically come to us for testing when standard gum disease treatment has not produced lasting results, when they want a holistic and personalized approach to oral health, or when they understand that the mouth is the gateway to whole body wellness and want to know exactly what is living there.
Benefits, Why MD Periodontics
- Precision targeted treatment, we treat the specific bacteria causing your disease rather than applying a one-size-fits-all approach
- Catches hidden infection, some of the most damaging oral bacteria cause minimal symptoms until significant bone loss has already occurred
- Whole body wellness insight, oral bacteria are linked to heart disease, stroke, diabetes, Alzheimer’s disease, pregnancy complications, and chronic inflammation, and testing gives you actionable information about your systemic health
- Personalized antimicrobial therapy, we use the test results to design targeted treatment, often reducing reliance on broad-spectrum antibiotics
- Identifies recurrence risk early, follow-up testing tells us whether treatment worked and whether harmful bacteria are returning before symptoms appear
- Beverly Hills specialist expertise, Dr. Moshrefi has decades of experience interpreting and applying microbiome data in complex cases, and Dr. Daneshmand brings USC-trained precision and a holistic philosophy to every personalized plan we design together
Who Is a Candidate?
Most patients with gum disease, complex periodontal cases, or a strong interest in personalized and holistic care are candidates for bacterial DNA testing. The test is safe, quick, and appropriate for nearly any adult.
You may be an ideal candidate if you:
- Have gum disease that keeps returning despite previous treatment
- Have ongoing inflammation or bleeding gums of unknown cause
- Have a failing dental implant or signs of peri-implantitis
- Have diabetes, heart disease, autoimmune conditions, or are pregnant
- Have a family history of aggressive periodontitis or early tooth loss
- Want a holistic, whole body approach to your oral and systemic health
- Are planning implants and want to confirm the foundation is healthy first
- Have unexplained chronic inflammation elsewhere in the body
There are virtually no contraindications to testing itself. Patients on certain medications, including recent antibiotic use, may need to time the test carefully so that the results accurately reflect their true microbiome.
The Process
- Comprehensive Evaluation and 3D Imaging. We begin with a thorough exam, full medical history review, periodontal probing to measure pocket depths, and a 3D cone beam CT scan when needed. This shows us exactly how much bone has been affected and where.
- Personalized Diagnosis and Plan. Together, we identify the type and stage of your disease and design a clear plan. We review every option, from non-surgical therapy to advanced regenerative procedures, with honest guidance on what each approach can achieve.
- Active Treatment. Depending on your case, treatment may include deep cleaning (scaling and root planning), laser therapy, antimicrobial treatment, regenerative bone and tissue grafting, gum grafting, or surgical pocket reduction. Most therapy is completed comfortably under local anesthesia.
- Healing and Re-Evaluation. Your gums and bone heal over weeks to months, depending on the procedures performed. We re-evaluate at follow-up visits to confirm pockets have shrunk, inflammation has resolved, and the disease is under control.
- Long Term Maintenance. Gum disease is a chronic condition, and ongoing care is essential. We design a personalized periodontal maintenance schedule, typically every 3 to 4 months, to protect your results and catch any recurrence early.
Recovery and What to Expect
There is no recovery period from the test itself. Sample collection is fast, painless, and requires no downtime. You can return to all normal activities immediately, including eating and drinking.
For best test accuracy:
- Avoid antibiotics for 2 to 4 weeks before testing when possible
- Avoid antibacterial mouthwash for 24 hours before testing
- Avoid eating, drinking, smoking, or brushing for at least 1 hour before sample collection
- Follow any specific lab instructions we provide for your test
Once results are available and we have designed your personalized treatment plan, recovery and care depend on the therapies you receive, which we explain clearly during your results review.
FAQ
No. Different bacterial species cause distinct disease patterns, with varying severities, treatment responses, and associations with systemic health problems. Testing identifies your specific situation and lets us treat the actual cause rather than the general category.
No. Different bacterial species cause distinct disease patterns, with varying severities, treatment responses, and associations with systemic health problems. Testing identifies your specific situation and lets us treat the actual cause rather than the general category.
No. The test uses a simple saliva sample or a gentle plaque swab and is completed in just a few minutes. There are no needles, no injections, and no discomfort.
Some plans offer partial coverage for periodontal diagnostic testing, especially when medically necessary. Coverage varies widely. Our team verifies your benefits and explains your out-of-pocket costs clearly before testing begins.
Most results return within 1 to 2 weeks. We schedule your results review as soon as your report is in, so we can move forward with your personalized plan promptly.
Modern tests identify the major periodontal pathogens including Porphyromonas gingivalis, Tannerella forsythia, Treponema denticola, Aggregatibacter actinomycetemcomitans, Fusobacterium nucleatum, and several others, along with quantifying their levels. We explain each one and what it means for your health.
Many oral bacteria, especially Porphyromonas gingivalis, have been directly linked to heart disease, stroke, Alzheimer’s disease, diabetes, rheumatoid arthritis, certain cancers, and pregnancy complications. Identifying and treating these bacteria supports far more than your smile; it supports your whole body wellness.
Not necessarily. One major benefit of testing is that it enables targeted therapy, often without the need for broad-spectrum antibiotics. When antibiotics are appropriate, the test guides us toward the most effective, narrowly focused option, reducing unnecessary exposure.
Initial testing establishes your baseline. Follow-up testing is typically performed 3 to 6 months after treatment to confirm the plan is working, then periodically based on your case. Patients with high systemic risk often benefit from annual monitoring.
Yes, to a meaningful degree. High levels of aggressive pathogens are a strong indicator of future bone loss, implant complications, and systemic inflammation, often before symptoms appear. Early identification gives us the chance to intervene before damage occurs.
Most general dental offices do not offer DNA-based microbiome testing. The advanced laboratory analysis we use identifies specific species at the genetic level, which is fundamentally different from visual exam, basic plaque assessment, or older bacterial culture methods.
Yes. Bacterial DNA testing is one of the core diagnostic tools in biologically minded and holistic periodontal care. It allows us to treat the cause rather than the symptoms, minimize unnecessary medication, and view your oral health as deeply connected to your whole body wellness, which is exactly how we practice.
Microbiome testing is only as valuable as the expertise to interpret and apply the results. Dr. Moshrefi has decades of experience treating complex periodontal and implant cases informed by microbiome data, and Dr. Daneshmand brings holistic, precision-based care to every plan we design together at MD Periodontics.
