Oral health often becomes an afterthought. The mouth is treated separately from the rest of the body until something hurts.
But the reality is: the mouth is the single gateway to everything else.
World Oral Health Day, observed on March 20 every year, serves as a reminder that oral health is indeed the front door to overall health.
This year’s theme says it simply: “A Happy Mouth is a Happy Life.”
And behind that line is a shift. A shift in how we think about prevention, access, and the role of technology in everyday oral care.
The bigger story: Oral health isn’t just about teeth anymore
The problem is much bigger than you think.
- Nearly 3.7 billion people globally are affected by oral diseases.
- Tooth decay is still the most common condition in the world.
What’s really changed is how we understand oral health itself. It is no longer looked upon as local. It’s systemic. Recent research in the space reveals that poor oral health is linked to:
- Cardiovascular disease: People with severe gum disease (periodontitis) have 34% higher risk of coronary artery disease.
- Diabetes: There’s a bi-directional relationship. Poor oral health makes blood sugar harder to control, while diabetes increases the risk of tooth loss.
- Cognitive decline: Emerging research in Alzheimer’s links chronic oral inflammation with accelerated neurodegeneration.
That’s exactly why the WHO’s latest 2026 guidelines push for a shift away from reactive dentistry, toward preventive, minimally invasive, and tech-enabled care.
So…why is dental care still so expensive?
Ask any patient, and you’ll hear it.
Dental care feels expensive because it is structurally complex.
Dentistry is one of the few fields where the doctor is also the surgeon, the radiologist, and the lab technician. The cost of sterilised surgical environments and biocompatible materials is immense.
But now, things have started to change.
AI is now catching problems before they become procedures. Early-stage detection means fewer crowns, fewer surgeries, and significantly lower long-term costs.
And the market is catching on.
In 2025 alone, DenTech funding crossed $2.1 billion, specifically targeting dentist-led startups that focus on prevent more, drill less.
Startups changing the oral care experience
Perceptive
Founders: Dr Chris Ciriello
Year: 2020 | Location: Boston, USA
We admire Perceptive for bringing “15-minute crowns” to reality. They use AI-driven robotics and advanced imaging that sees inside the tooth without X-rays, allowing a robot to prepare a tooth and place a final restoration in a single, incredibly fast visit.
Grin
Founders: Dr Adam Schulhof, Pamela Oren-Artzi and Alon Lipnik
Year: 2019 | Location: New York, USA
We admire Grin for bridging the gap between the clinic and the home. Their “Grin Scope” attaches to a smartphone, allowing orthodontists to monitor tooth movement and gum health remotely, ensuring specialist-led care with fewer in-person appointments.
Two Front
Founders: Dr Ingrid Murra
Year: 2019 | Location: Los Angeles, USA
Two Front is bringing orthodontists into every dental clinic. It provides a virtual operating layer that allows orthodontists to collaborate with general dentists, enabling “office-less” specialist care within existing clinics.
Smile in Hour
Founders: Dr Bharat Agravat
Year: 2014 | Location: Ahmedabad, India
We admire Smile in Hour for its focus on “Smart Clinic” protocols and affordable home care. They pioneered the OSMF (Oral Submucous Fibrosis) mouth-opening kit, helping patients manage chronic conditions at home while offering 1-hour in-office laser cosmetic treatments.
Pearlii
Founders: Dr Kyle Slater
Year: 2020 | Location: Melbourne, Australia
Pearlii uses AI to provide free dental check-ups to anyone with a smartphone. Users simply take five photos of their teeth and gums, and the app’s AI scans for signs of decay, gingivitis, or staining, providing an instant report and connecting users to affordable local care.
DentalMonitoring
Founders: Philippe Salah, Emmanuel Salah, and Armelle Coquart
Year: 2014 | Location: Paris, France
We admire DentalMonitoring for pioneering remote orthodontic tracking through AI. Their platform allows patients to scan their teeth at home using a smartphone; the AI then analyzes the images to track tooth movement and gum health, allowing orthodontists to monitor progress without requiring the patient to come into the office every few weeks.
Dentulu
Founders: Dr Arash Hakhamian and Shivakumar Chandrasekaran
Year: 2017 | Location: Los Angeles, USA
Dentulu has created a “dental office in a pocket.” This dentist-led platform provides teledentistry consultations and a mobile network that can bring professional cleanings and emergency care directly to a patient’s home or office, making care accessible for those with mobility issues or busy schedules.
scanO
Founders: Dr Vidhi Bhanushali and Rajat Kabade
Year: 2020 | Location: Pune, India
scanO is making dental screening contactless and immediate. Using just a smartphone app, their AI scans photos of a patient’s mouth to provide an instant risk assessment, catching problems like gum recession or cavities before they cause pain.
Where oral care is headed
We see clear shifts emerging in oral care:
- The mouth-body connection: Oral health is now officially recognised as a primary pillar of non-communicable disease (NCD) prevention.
- AI is the new standard: “Are AI dental tools accurate?” Yes. In 2026, AI is no longer a luxury but a standard tool for diagnostic validation and insurance claim transparency.
- Sustainability: Following the new WHO guidelines, the industry is pivoting toward mercury-free and minimally invasive materials.
- Prevention over restoration: The most valuable “tech” in 2026 is anything that keeps a patient out of the dental chair for major surgery by catching issues at the molecular or digital level.
The bottom line
The future of oral care isn’t about better drills. It’s about catching problems earlier, reducing friction, and making care accessible, no matter where you are.
Because at the end of the day, this isn’t just about teeth.
It’s about making sure more people can keep their health and their smile for life.
And World Oral Health Day is here to remind that!
