Episode Details

The episode opens with Dr. Krishna Vedala framing dental health as a major public‑health issue: untreated cavities and gum disease affect millions, worsen chronic conditions such as heart disease, diabetes, and respiratory illness, drive costly emergency care, and reduce quality of life and economic productivity. Expanding prevention, education, and affordable treatment can improve population health and lower long‑term medical costs.

Dr. Tina Saw introduces herself and Oral Genome, describing her path from art and clinical dentistry to an interest in the mouth‑body connection. She explains Oral Genome's 15‑minute chairside saliva test that uses AI and machine learning to analyze oral biomarkers, enabling rapid point‑of‑care risk assessment so clinicians can develop immediate treatment and prevention plans rather than waiting for disease to appear on X‑rays or probes.

They discuss the entrenched separation between dental and medical care—separate insurance, limited cross‑training, and fragmented referrals—which worsens outcomes. Dr. Tina Saw emphasizes that saliva contains systemic signals, including biomarkers linked to cardiovascular risk, and argues that integrated testing and closed‑loop referral systems would let dentists and physicians coordinate care and reduce downstream medical costs.

Access barriers for underserved and rural communities are highlighted: low Medicaid reimbursement, provider shortages, transportation challenges, and food insecurity. Dr. Tina Saw advocates for targeted incentives such as loan forgiveness and rural‑centered training programs, portable screening and mobile care, and policy changes to improve reimbursement so providers remain in Medicaid networks and preventive services reach high‑need populations.

The episode addresses water fluoridation and the spread of misinformation. Dr. Tina Saw and Dr. Krishna Vedala defend community water fluoridation as a proven, low‑dose public‑health measure that strengthens enamel and reduces caries, noting recent rollbacks and warning that removing fluoride could increase cavity rates while misinformation fuels opposition.

Looking ahead, Dr. Tina Saw proposes system changes: routine dental well checks that include portable X‑rays and saliva testing, mandatory interoperability and care coordination between dental and medical systems, and strategic use of telehealth for triage—not as a substitute for in‑person procedures. She encourages future dentists to prioritize prevention and integration, arguing these steps will catch disease earlier, lower costs, and improve overall health.

Where Health, Society, and Innovation Intersect

Connected by Health is a forward-thinking podcast built on a simple but powerful truth: healthcare is not a cost to be cut — it is an investment that shapes the future of everything around us.

Millions of people struggle with healthcare challenges each year — whether it's lack of insurance, unaffordable costs, limited access to care, or managing chronic disease — affecting not only their health, but their financial stability and overall quality of life. Their stories are not isolated — they are all connected. From economic growth and workforce productivity to education, technology, national security, and community stability, health is the thread weaving them together.

Each episode blends real-world stories with data-driven insight to show how strategic healthcare investment drives innovation, reduces long-term costs, strengthens public health infrastructure, and fuels economic resilience.

Grounded in evidence but driven by purpose, Connected by Health reframes healthcare not as a line item expense, but as foundational infrastructure — because when we invest in health, we invest in people, potential, and the strength of our entire society.
