New technology helps teeth break back

A new technology invented by Canadian researchers at the University of Alberta has made an unexpected breakthrough: to make adult broken teeth grow back.

According to Globe and Mail, researchers placed a small pea ultrasound device in the patient's mouth. The device has the function of stimulating the gums thanks to light massages that help root growth.

A 20-minute stimulation every day for 4 weeks can produce good results. In the long term, this technique can also be used to stimulate bones in the body, which helps increase height. Researchers hope to launch this product in about 2 years.
