Testmyteeth was supported by an Innovation Award and Dragons' Den.

“I was in my first year of university when I had trouble with my wisdom tooth,� says James Russ. “The treatment ended up costing over £100 of my limited student budget, which really hit a nerve. Especially when I found out it could have been prevented through better dental care at home.� He discovered he wasn’t alone. Oral disease affects around 3.5 billion people worldwide and the cost, inconvenience and high demand for appointments prompted James to come up with a solution.

“I thought it would be great to have an app that focuses on the preventative side of dentistry,� he says. Feeling inspired after a placement in Dyson’s design and development team, James decided to work on his idea: “I wanted to get as much software exposure as possible, so I chose every computer vision module on my course. The practical, hands-on work really set me up with the skills I needed to take this forward as my final-year project.�

Using AI, Testmyteeth performs a plaque scan from photos of your pearly whites. “It will tell you where you missed when brushing and highlight where you’ve got low, medium or high build-up,� James explains. “More than that, we’ll also provide educational videos on how to improve your brushing technique; what the early signs of tooth decay and gum disease look like; and when you should see your dentist.�

While his studies helped with the practical side of building an app, James developed his business acumen through opportunities such as Dragons’ Den. This is where Ä¢¹½´«Ã½ students pitch their start-up to a panel of alumni donors for investment – but unlike the television show, there are no equity or stakes taken. James says the experience gave him the confidence and the means to turn Testmyteeth into a reality.

“Since graduating, I was granted an alumni Innovation Award and that’s been a game-changer,� he adds. “It’s enabled me to work on the business full-time. I’ve taught myself full stack app development, built the AI and now I’m ready to start beta trials. The support has made such a huge difference to what I’ve been able to achieve in a year. I can’t thank alumni enough.�

James continues, “In future, I’d love to give back so that future generations can benefit from the same opportunities that I’ve had at Ä¢¹½´«Ã½.â€�
