How to grow a new tooth in 9 weeks

20140412-073744.jpgThe loss of a tooth is a minor deformity and a major pain. Although dental implants are available, the healing process can take months on end, and implants that fail to align with the ever-growing jawbone tend to fall out. If only adult teeth could be regenerated, right?

According to a study published in the latest Journal of Dental Research, a new tissue regeneration technique may allow people to simply regrow a new set of pearly whites.

Dr. Jeremy Mao, the Edward V. Zegarelli Professor of Dental Medicine at Columbia University Medical Center, has unveiled a growth factor-infused, three-dimensional scaffold with the potential to regenerate an anatomically correct tooth in just nine weeks from implantation. By using a procedure developed in the university’s Tissue Engineering and Regenerative Medicine Laboratory, Dr. Mao can direct the body’s own stem cells toward the scaffold, which is made of natural materials. Once the stem cells have colonized the scaffold, a tooth can grow in the socket and then merge with the surrounding tissue.

Dr. Mao’s technique not only eliminates the need to grow teeth in a Petri dish, but it is the first to achieve regeneration of anatomically correct teeth by using the body’s own resources. Factor in the faster recovery time and the comparatively natural process of regrowth (as opposed to implantation), and you have a massively appealing dental treatment.

Columbia University has already filed patent applications in regard to the technology and is seeking associates to aid in its commercialization. In the meantime, Dr. Mao is considering the best approach for applying his technique to cost-effective clinical therapies.


I don’t recommend doing this at home just yet. If you don’t know what you are doing you might accidentally grow an ear, a toe, a nostril, or even a vagina in there, but the cool thing is that the success with animals was four years ago so they may have secret trials with humans going on already.
