Researchers in Canada have shown that new fluoride-free toothpastes with hydroxyapatite can provide equivalent protection to those containing fluoride.

Kelsey O’Hagan-Wong, a second-year pediatric dentistry resident at the University of Toronto’s Faculty of Dentistry, was the first author of a review paper published in Odontology that investigated the efficacy of fluoride-free hydroxyapatite toothpastes on re-mineralising and therefore repairing teeth. Through her research, she found that hydroxyapatite toothpastes appear to demonstrate either its superiority or equivalency to fluoride toothpaste as anti-caries agents.

Typically, fluoride is used in the prevention of dental caries, but due to the decreased acceptance among the public and the risk of fluorosis in children, there is the need for effective alternatives. Hydroxyapatite is the main mineral of human tooth enamel and can be used in toothpastes as a biomimetic active ingredient.

“Fluoridated toothpaste is often a concern for very young kids who are more likely to swallow it,” O’Hagan-Wong said.

“The problem is kids are getting cavities, so there needs to be an alternate solution.”

Hydroxyapatite products can be considered as an alternative in young children where fluorosis is a concern. The challenge is the toothpastes are often expensive, difficult to obtain and not well-known.

“Although this toothpaste has been on the market for a while, most people are unaware of it,” O’Hagan-Wong said. “Hopefully with more knowledge, it can be used to prevent cavities.”

O’Hagan-Wong believes more can be added to fluoride-free toothpastes to further improve and protect teeth. Her master’s research involves looking at adding a special protein to hydroxyapatite toothpaste that can help rebuild the tooth and prevent further decay.
