Several new treatments are under development. One experimental technique uses fluorescent light to detect the development of cavities long before they can be detected by traditional means, such as X-rays or dental examination. In many cases, if cavities can be detected early, the decay process can be stopped or reversed. Researchers are also working on a “smart filling” to prevent further tooth decay by slowly releasing fluoride over time around fillings and in adjacent teeth.
New ways to prevent tooth decay are also being studied. A study showed that a chewing gum containing the sweetener xylitol temporarily retarded the growth of bacteria that cause tooth decay. Also under research are several materials that slowly release fluoride over time to help prevent further decay. These materials would be placed between teeth or in pits and fissures of teeth. Toothpastes and mouth rinses that can reverse and “heal” early cavities are also being studied.
