Depending on the cavity’s depth, this method can beunpleasant to downright painful for the patient, and it has to be repeated periodically.         “You’re really in that cycle of repair and replacement for the rest of the tooth’s life,” said RebeccaMoazzea, senior lecturer at King’s College.         A damaged tooth’s enamel can be replaced naturally, but the process is too slow to stop the work of bacteriathat build up in tiny cracks. Now, a British company called Reminova has developed a method for speeding upthis natural remineralization of early-stage cavities.         “We’ve just found a way to make that a much faster process,” said Jeff Wright, Reminova’s chief executiveofficer. “Driving healthy calcium and phosphate minerals into your enamel, and through a natural process, itwill bind on and add to the enamel that’s there.”         Here’s how it works: After cleaning the early-stage cavity with a method that does not require drilling, thedentist covers it with a mineral solution and applies an electrical current that is too weak for the patient to feel.The deposited mineral quickly hardens, completely filling the cavity.         Researchers say this method could be especially useful for children.         “If children have a better experience of going to the dentist, so they haven’t had necessary drilling andinjections for routine fillings, then they’ll be much more positive in later life and probably become much moreregular patients,” said Dr. Barry Quinn, a consultant at King’s College.         Dentists point out that the new method is most efficient on early-stage cavities, which makes regular dentalcheckups essential. The whole treatment lasts about as long as a regular drill-and-fill procedure.         Researchers say they are confident that the new method can be further developed for treating later-stagecavities. And they remind us that regular brushing with fluoride toothpaste helps prevent cavities in the firstplace.
