Smile! A new Canadian tool can re-grow teeth say inventors

Snaggle-toothed hockey players and sugar lovers may soon rejoice as Canadian scientists said they have created the first device able to re-grow teeth and bones.

The researchers at the University of Alberta in Edmonton filed patents earlier this month in the United States for the tool based on low-intensity pulsed ultrasound technology after testing it on a dozen dental patients in Canada.

"Right now, we plan to use it to fix fractured or diseased teeth, as well as asymmetric jawbones, but it may also help hockey players or children who had their tooth knocked out," Jie Chen, an engineering professor and nano-circuit design expert, told AFP.

Chen helped create the tiny ultrasound machine that gently massages gums and stimulates tooth growth from the root once inserted into a person's mouth, mounted on braces or a removable plastic crown.

The wireless device, smaller than a pea, must be activated for 20 minutes each day for four months to stimulate growth, he said.

It can also stimulate jawbone growth to fix a person's crooked smile and may eventually allow people to grow taller by stimulating bone growth, Chen said.

Tarek El-Bialy, a new member of the university's dentistry faculty, first tested the low-intensity pulsed ultrasound treatment to repair dental tissue in rabbits in the late 1990s.

His research was published in the American Journal of Orthodontics and Dentofacial Orthopedics and later presented at the World Federation of Orthodontics in Paris in September 2005.

With the help of Chen and Ying Tsui, another engineering professor, the initial massive handheld device was shrunk to fit inside a person's mouth.

It is still at the prototype stage, but the trio expects to commercialize it within two years, Chen said.

The bigger version has already received approvals from American and Canadian regulatory bodies, he noted.

Wow, I wonder how long it would take for FDA approval? I had a molar removed a few years ago, I didn't want to spend the money to get a porcelain replacement.

Wow. I wonder if it works on soft tissue too? Could be used to regenerate pancreatic cells in diabetics?

Interesting indeed. I remember reading an article about regrowing teeth with stem cells. Working on this in England, I think.

Well, I have it worse: I am about to lay out painfully large sums for two crowns and some bridgework. A-g-e is stalking me and closing.

...and it STAYS stimulated, so a new, full set of teeth begins growing in every 3-4 years, forcing the extraction of the previous set.

I wonder if it will be useful for people with osteoporosis.

If this works, I doubt they'll charge a whole lot less for the "new tooth" treatments as opposed to the cost of crowns and veneers, so...

I was just kidding about the disappointment. This stuff is years away from actually being a feasible treatment. I wouldn't be surprised if this were priced higher than conventional cosmetic dental restoration methods. I would rather have real teeth than porcelain crowns on my upper incisors. Quite frankly it would be great if I could grow a new set of teeth every 25 years or so. All my teeth were discolored by exposure to tetracycline, and it is impossible to get rid of that discoloration. I got a couple of veneers on my bicuspids just so I could get a lighter shade of across all four teeth.

That would be a huge boon to almost everyone, myself included.

I feel your pain, as a kid I lived in a city that overdid the flouride in the water supply, with a similar result.

Years ago, I read a report ( with no further confirmation ) about a woman nearly a hundred years old who grew a new set of teeth. Always wondered about it.

Sabres Defenseman, Rob Siegel Plano Sabres star defenseman, Rob Siegel, is second on the team in goals, assists and points (19-17-36) and first in penalty minutes (42) at the midway point of the season (through 20 games). On Tuesday, January 30, 2001 in a game against the Maple Leafs, Rob Siegel took a nasty deflection off a Curt Johnson slapshot to the face and had to leave the game. The puck hit him just above the chin, took out one upper tooth completely and chipped two other teeth as well. It also severed the nerve controlling his lower lip, which may or may not have permanent effects. He was in surgery until 4 am with a plastic surgeon on call at Plano General Hospital, but is home now with a big supply of medication. He needed about 100 stitches (most of them internal stitches).
