Breakthroughs in dental research point to being able to regrow teeth

teethRecently announced results of research in Canada and in the US are bringing exciting encouragement to patients with a variety of  dental and periodontal problems.

Researchers at the University of Alberta in Edmonton (Canada) announced they’ve created a technology that will allow patients to regrow teeth.

Using a miniaturized system-on-a-chip based on low (LPUS) technologythat delivers a non-invasive way to stimulate jaw growth and dental tissue healing, the tiny device will be able to fit comfortable inside a patient’s mouth, mounted easily on an orthodontic or “braces” bracket or even a plastic removable crown. This innovative technology would effectively eliminate the need for artificial bridge implants.

Researchers hope to have a marketable product within the next two years.

In the U.S., Dr. Jeremy Mao, professor of dental medicine at Columbia University, has developed a technique that would allow dental implants to be grown inside a patient’s mouth, in their empty tooth socket.

Instead of the traditional method of harvesting stem cells and growing them in a petri dish Dr. Mao begins with a scaffold-like structure made from microchannelled natural materials, infused with a growth factor. Placing this in a patient’s mouth in the empty socket, stem cells naturally migrate onto the scaffold, creating a new tooth-like structure, regeneratng periodontal ligaments and forming new alveolar bone.

A new tooth could potentially be grown in as little as nine weeks!

The study was published in the most recent issue of the Journal of Dental Research, the top-rated, peer-reviewed scientific journal.

The possibility of regrowing human teeth has been viewed for years as science fiction. Now consumers may have a truly “natural” choice  within the next two years. That’s something to keep an eye on.

  1. The stories that you have cited and the way in which you have cited them are a bit uninformative. The Canadian product was first cited in 2005, and as of today – five years later- the product has yet to reach the market. In either case, the product is only meant to help in enamel reformation which requires that the basic tooth structure including dentin and root to remain endogenously.

    The other post which you have cited was published recently in May. However, to suggest that the research will be allowed to move on clinically in two years time is ambitious to say the least. If you read through the scientific paper published by Dr. Mao the research has been shown effective in mice with a crown like structure surrounding the implant. In this case, dentin was shown to regenerate. Not the entire root structure of the tooth or perhaps as importantly the enamel which encases the tooth.

  2. Is there anywhere I can purchase a unit for personal use ?

    • Not that I know of. As far as I can tell, it’s still in the testing stage, but if and when it makes it to commercial use, I’ll definitely do a post about it. I’d like to sign up for this one too!
