Disease and decay are a constant threat to your teeth, gums and overall health. Once we can see decay with the naked eye, it usually means severe damage has already occurred. DIAGNOdent Diagnostic Laser technology is the latest breakthrough in decay detection. When the laser detects decay, it gives us both visual and audio cues. The higher the pitch and measuring number, the more decay is present in the area scanned by the laser. This kind of diagnosis helps us detect decay that is concealed deeper and/or smaller in nature. The DIAGNOdent is helpful in detecting decay under old restorations such as metal fillings and crowns that are somewhat detached or loosened from natural tooth wear. Most significantly the DIAGOdent helps differentiates between stains in the grooves of teeth from active decay, and is thus critical tooth to early tooth decay detection.
