No more fillings? The future of dental health
What if cavities or cracked or broken teeth could be repaired without dental fillings?
But scientists are studying how to grow dental stem cells in a lab to try to transform how dentists treat teeth, imagining a future in which tooth enamel or whole teeth could be replaced. "It would be a great advance in the field if stem cells could be used to repair cavities or treat other oral health issues," says senior study author"The tooth provides an excellent source of stem cells,” he says, and his team can make them grow and produce a lot more cells.
In the future, this might mean biobanks routinely store tissue from wisdom teeth that get pulled, so that dentists could use this tissue when oral health problems develop down the line.Of course, many more lab tests and clinical trials will be needed to see if, one day, dentists can use dental stem cells to fill cavities and fix damaged teeth safely and effectively.
