REGROW YOUR ROTTEN TEETH; New cavity cure could put an end to fillings.Byline: By Donna Watson
FILLINGS could soon be a thing of the past, as scientists develop a way to make decayed teeth regenerate and "heal".
The technique involves implanting crystals into cavities. Once perfected, it will eliminate the need for fillings.
Instead, enamel and dentin dentin /den·tin/ (den´tin) the chief substance of the teeth, surrounding the tooth pulp and covered by enamel on the crown and by cementum on the roots.den´tinal
adventitious dentin secondary d. - the materials that make teeth so strong - will be regrown from the crystals, which are contained in a calcium solution.
The key will be to spot the decay early enough for dentists to get teeth to grow healthy tooth-matter.
Professor Sally Marshall, who is leading the research at the University of California The University of California has a combined student body of more than 191,000 students, over 1,340,000 living alumni, and a combined systemwide and campus endowment of just over $7.3 billion (8th largest in the United States). at San Francisco, said: "What we're hoping to have happen is to catch decaying teeth early and remineralise them."
The ability to use the body's own building materials would be a boon to dentists, who have been fixing cavities with metal fillings since the 1840s.

chemical science, chemistry - the science of matter; the branch of the natural sciences dealing with the composition of substances and their properties and the enamel coating of the teeth, allowing bacteria to break through to the dentin inside.

b. and useless, causing a cavity.
Prof Marshall's work focuses on regrowing the dentin using the calcium solution.
She has already been able to use it to remineralise some parts of test teeth and is confident it will soon be possible to repair entire teeth.
The research was unveiled at the spring meeting of the Materials Research Society.
