A Nova Scotia company says it's offering peace of mind to dentists and patients who undergo a procedure as part of a multi-billion dollar industry. 

White composite or plastic  fillings are a popular choice among many people in the North American market because they look more natural than amalgam fillings. White fillings are a $36-billion industry in North America.

White fillings are also more expensive and tend to be not as strong as their metal counterparts. To ensure plastic fillings are as strong as possible, the blue light used to cure or “bake” the plastic must be sufficiently strong.

If the blue light is weak, the fillings will flake apart. 

“If a dentist picks up a light and sees that it’s blue, they think ‘Great it’s working.’ The problem is you just don't know how well it’s working,” said Chris Lee, a dentist at Dalhousie’s dental school.

Nova Scotia based BlueLight Analytics, which developed its technology at Dalhousie’s dental school, says it has a solution.

Colin Deacon, the company’s president, said for $50 his company will pay a visit to the dental office and test their blue lights. 

“If they don’t have enough blue light, they’ll fall out,” he said.

BlueLight has exports worth about $1 million — about the same amount as what taxpayers have contributed to the company.   

Deacon said the company could soon be making more money if it lands a pitch made to a military conference last month.

“Within three years of a new recruit joining the U.S. navy, 30 per cent of their fillings had to be replaced and that volume of business was becoming a problem,” he said.
