Beams of the low-power laser can regenerate the damaged teeth.
and eliminate the need for replacing them.
the laser induces human dental stem cells to form dentin.
dentin is a tissue harder than bone and forms the major portion of the tooth is located above an area called dental pulp.
a low -dose of laser focused on this area induces stem cells to regenerate dentin.
the laser actives a special protein called TGF-B1.
TGF-B1:is a growth factor that regulates cell growth and differentiation.
the new approach could one day replace the root canal treatment which is the very painful producer
it involves removal of tooth's nerve blood vessels .
researchers hope to test laser treatment in humans in near of future.
