Cavity Detection Laser


Sometimes, it’s difficult for us to diagnose cavities, especially in the pits and grooves on the biting surfaces of your back teeth. The traditional way to check for cavities was by looking for visual signs of decay on the tooth, checking X-rays, or feeling for a soft area with a dental explorer. However, we now have a diagnostic tool called the Diagnodent that helps us locate even the smallest amount of decay.

Diadnodent is a laser technology that scans your teeth with harmless pulses of light. When a cavity is present, flourescent light of a different wavelength bounces back to the sensor, which is translated to a digital read-out. In general, the higher the number, the greater the amount of decay in the tooth. When a cavity is present, the Diagnodent also produces an audible sound.
