4. Laser Technology
Scientists at the University of Buffalo in New York think that lasers might also be able to help regrow dentin. They found that shining a low-power laser light at remaining pulp may also stimulate stem cells to start producing dentin again. Figuring out how to trigger stem cells is a huge boon with many potential health applications.
When it comes to teeth, the laser procedure likely won’t eliminate the need for dead teeth to undergo a root canal and be covered with a crown. But, the existence of new dentin does strengthen the tooth that’s left and might very well extend the life of the crown that’s installed.
Normally, the pressure of biting and chewing food weakens the glue that holds a crown in place, so it needs to be replaced every so often.
