CARDIFF, Wales: As humanity continues to lean into artificial intelligence (AI) and digital technologies for all manner of basic life challenges, the realm of an individual’s oral healthcare too is evolving. While the dentist’s office remains the definitive space for diagnosis and treatment, mobile apps are being developed to offer patients supplementary support. TestMyTeeth, for example, is an AI-powered app for at-home plaque screening. A new study by researchers in Wales has cast a critical yet constructive spotlight on the app, showing that, while it has potential to support preventive oral healthcare, it falls short in user friendliness and requires significant technical improvements.
