The Guardian reports -
The procedure is fairly simple. Doctors take stem cells from the patient. These are unique in their ability to form any of the tissues that make up the body. By carefully nurturing the stem cells in a laboratory, scientists can nudge the cells down a path that will make them grow into a tooth. After a couple of weeks, the ball of cells, known as a bud, is ready to be implanted. Tests reveal what type of tooth – for example, a molar or an incisor – the bud will form. Using a local anaesthetic, the tooth bud is inserted through a small incision into the gum. Within months, the cells will have matured into a fully-formed tooth, fused to the jawbone. His team has set up a company, Odontis, to exploit the technique, and has won £400,000 from the National Endowment for Science, Technology and the Arts and the Wellcome Trust.
