We can regrow teeth!
Grow a replacement tooth rather than installing foreign objects.
The treatment, called low-intensity pulsed ultrasound, massages the gums to stimulate jaws, encourage growth in the roots of teeth and aid healing in dental tissue.
El-Bialy discovered ultrasound could be used to form new dental tissue from his research on rabbit incisors, which was published in the American Journal of Orthodontics and Dentofacial Orthopedics.
He then tested the technique on people who needed to get their teeth pulled.
Participants held the bulky ultrasound device for 20 minutes a day for four weeks against a tooth that had a problem, such as erosion after a root canal.
When El-Bialy looked at the extracted teeth under the microscope, he found new tissue was added to the roots of treated teeth, but not to untreated ones. The therapy regenerates the inner part of the tooth, but not the enamel.
The team has filed for a patent on their prototype in the U.S. They expect to have a version that is ready for patients within two years.
