New technology has enabled dentists to detect cavities much earlier than is presently possible using X-rays. The technique, known as quantitative light fluorescence works by using a high-intensity light beam to evaluate calcium and phosphate loss in the teeth. Dr GK Stookey from Indiana University School of Dentistry said, "By the time we can detect dental carries today--through X-ray and visual exams--they are often 2 years old or older.

By using quantitative light fluorescence, dentists are able to detect the cavity almost as soon as it begins to develop. Detecting tooth decay at an early stage results, in the majority of cases, in salvage of the tooth or removing the need for fillings.
