Researchers Discover That Lasers Can be Used to Generate New Tooth Growth
In a groundbreaking study published this week in Science Translational Medicine, researchers say that a low-powered laser could be the key to creating new tooth growth. In the lab, the Harvard-led team were able to use lasers to "turn on" a natural healing cycle, which caused dentin to regrow inside teeth. This technology could allow a cavity to essentially "fill itself" back in with healhy tooth tissue, or enable a broken tooth to regrow again.Although the technology has only been tested on rats so far, it is possible that human clinical trials could begin within the year. "There's potential for this to be broadly useful," says David Mooney, the paper's senior author and a Harvard University bioengineer. If the approach works, the implications stretch beyond just avoiding the “drilling an...
