The DIAGNOdent® is a high-tech tool that allows us to find cavities on the chewing surfaces of back teeth, even when they are just beginning and would have been missed by previous detection methods. The DIAGNOdent is a small, portable laser unit that detects the cavity and alerts us with an audible signal and a numerical readout, so that we have an idea of the cavity’s size. The added benefit is that we can stop cavities in their infancy, whereas in the past they would have to be significantly bigger before we could find and treat them. Just like other areas of medicine and dentistry, early detection and treatment is of immeasurable value in preserving your health.
