AI that spots cavities, virtual dentists, 3D-printed crowns, and a $499 camera toothbrush: dentistry is having a wild tech moment

Dyson's new CameraJet (a ~$499 toothbrush with a built-in camera and AI that "flosses" as you brush, launched 1 September) got all the attention, but it's really just the consumer-facing tip of a much bigger shift in oral health tech:

• AI-assisted imaging helping dentists spot cavities and bone loss earlier on scans
• Teledentistry (virtual consults) widening access, projected at ~30% of consultations by 2026
• 3D printing and digital scanners enabling same-day crowns and clear aligners (goodbye goopy impression trays)
• Smart home devices (sensors, timers, and now cameras) trying to fix how badly most of us brush, the WHO reckons oral diseases affect ~3.5 billion people

And it's a big, fast-growing market, especially in Asia, the Gulf and Africa: Asia-Pacific is one of the largest oral-care regions (~$13-15bn in 2025, led by China and India), and the Middle East & Africa market is ~$4bn and rising, with the UAE a major contributor (figures vary by source).

Here's the interesting bit for anyone thinking about the investing side: the flashiest gadget isn't necessarily where the money is. Dyson grabs headlines, but you can't even buy it, it's privately owned. The real momentum is with the big, established brands that keep quietly growing. Invisalign (made by Align Technology) has turned clear aligners into a massive global category and is still expanding, especially with younger consumers and in Asia. Oral-B (owned by P&G) and Philips Sonicare dominate electric brushes and keep pushing premium, connected models. Waterpik (owned by Church & Dwight) made water-flossing mainstream. These are the household names actually winning shelf space and market share as the category premiumises, and unlike Dyson, they're listed companies you can research.

Would you ever pay $499 for a "smart" toothbrush, or is that peak gadget nonsense?
