A tooth (plural teeth) is a small, calcified, whitish structure found in the jaws (or mouths) of many vertebrates and used to break down food.
That is right. Scientists can help the body grow a new tooth in about two months. Gone will be the days of dentures and painful tooth implants.
“Key consideration in tooth regeneration is finding a cost-effective approach that can translate into therapies for patients who cannot afford or who are not suitable candidates for dental implants,” Dr. Mao said. “Cell-homing-based tooth regeneration may provide a distinct pathway toward clinical translation.”
In other words, it is may be a less expensive process. However, one thing that is known for sure is that it is far less invasive.
“Dental implants usually consist of a cone-shaped titanium screw with a roughened or smooth surface and are placed in the jaw bone. While implant surgery may be performed as the outpatient procedure, healing times vary widely, and successful implantation is a result of multiple visits to certified clinicians, including general dentists, oral surgeons, prosthodontists, and periodontists.”
It might just be me, but the thought of a titanium screw anywhere near my mouth gives me the chills.
A new technique pioneered at the Tissue Engineering, and Regenerative Medicine Laboratory of Dr. Jeremy Mao, Edward V. Zegarelli Professor of Dental Medicine, and a professor of biomedical engineering at Columbia University can orchestrate the body’s stem cells to migrate to three-dimensional scaffold that is infused with the growth factor. This can yield an anatomically correct tooth in as soon as nine weeks once implanted in the mouth.
By growing a new tooth in the location where one lost a tooth, all issues associated with implants or dentures are gone. “This is a much-needed medical advancement, especially considering that by age 75—26% of adults have lost all of their permanent teeth.”
