LONDON, England -- False teeth could become a thing of the past thanks
to stem cell technology, scientists at London University say.

Successful tests on mice show the technology may let people grow their
own replacement teeth.

The London team at Kings College have been awarded £500,000 ($887,500)
to further their research and have set up a private company, Odontis,
to develop their plans.

The scientists say the technology will allow those with missing teeth
to fill the gaps in their mouth without having to resort to false
teeth, bridges or synthetic implants.

The technology works by taking stem cells -- "master" cells that can
be programmed to make different kinds of tissue -- from the patient
which are treated and cultured in the lab.

They are then re-implanted in the patient's jaw under the gum where
the tooth is missing.

Prof. Paul Sharpe, the genetic research scientist behind the
technique, told the UK's Press Association that it was hoped the tooth
would then grow into a fully-formed, live tooth in around two months.

He said the technique had been tested in mice and they hoped to move
on to trials in humans in the next two years.

But it could be five years before the technology is widely available
to the general public.

The researchers are testing the success of stem cells taking from
different parts of the body, such as from bone marrow or teeth
themselves.

Prof. Sharpe, head of division of Craniofacial Biology and
Biomaterials at the Dental Institute at King's College, said the cost
should not be more than the current price tag for synthetic implants
-- around £1,500 ($2,660) -- £2,000 ($3,550).

"A key advantage of our technology is that a living tooth can preserve
the health of the surrounding tissues much better than artificial
prosthesis," he told PA.

"Teeth are living, and they are able to respond to a person's bite.

"They move and in doing so they maintain the health of the surrounding
gums and teeth," he said.

In the UK and U.S., people over the age of 50 lose an average of 12
teeth from a full set of 32.

Problems associated with loss of teeth include general health,
nutrition and physical appearance.

Prof. Sharpe's project has been awarded £300,000 ($532,500) from the
Wellcome Trust, £100,000 ($177,500) from the National Endowment for
Science, Technology and the Arts (NESTA) and £100,000 from a business
sponsor.

Mark White, invention and innovation director at NESTA, told PA:
"Odontis have come up with a dental method that is highly innovative
and pioneering in its approach.

"We hope that our seed investment will bring about a major success
story for the UK research and science community."

A spokesman for the British Dental Association (BDA) told PA: "The BDA
welcomes projects like Odontis and looks forward to seeing further
progress in this field.

"The BDA is also pleased to see the level of investment for this
project from NESTA and hopes that future oral health projects will be
given similar priority."
