Dentomi (DTOMI Limited) demonstrates GumAI, a computer-vision oral-health tool that turns a phone camera into a fast, at-home dental screening flow. You take an intraoral photo with a smartphone or iPad, and the app returns an annotated view that highlights where brushing or flossing needs more attention, using a simple green/yellow/red overlay aimed at coaching rather than replacing a dentist visit. https://www.dentomi.biz/
Under the hood it maps a familiar dentistry step—visual inspection—into an AI pipeline: guided image capture, quality checks (focus, lighting, framing), then pixel-level segmentation and classification to mark gingival margins, plaque-heavy zones, and other visible hygiene indicators. The practical value is repeatability, so people can track changes over time and tighten daily technique at home.
The team frames it as access tech for communities that don’t get regular dental care, with deployments via NGO partners, community centres, and elderly homes. In the interview (filmed at CES Las Vegas 2026), they also describe collaborations in Hong Kong, including sponsorship-style rollouts with Colgate-Palmolive that remove cost barriers and support preventive follow-up for health equity.
Ward describes a dentist and public-health background and an ongoing PhD at the University of Hong Kong, with the product starting as research intended to translate into community impact. Training follows the typical supervised-learning path: labeled clinical photos from partner clinics and hospitals, plus additional user images when consent is granted, which brings up real questions around data governance and privacy.
Commercially, the model leans toward funded access—brands, dental associations, or public programmes cover licences so end users can scan for free, while the system can nudge referrals when risk looks elevated. It’s easy to imagine insurer and teledentistry tie-ins later, but the core framing stays consistent: image-based screening and education that helps people decide when to seek care and how to improve day-to-day habits before issues grow, prompting timely act.
