Cavities are not always readily apparent and can be difficult to diagnose, especially if they are on the back of the teeth and other difficult to see areas. Diagnodent is a safe and harmless laser that uses fluorescent light to scan for cavities. When a cavity is found, the light that bounces back to the sensor is of a different wavelength and this is displayed on a digital readout. The larger the cavity the greater the wavelength deviation and the higher the readout. An audio signal ensures that no cavity is missed.

With Diagnodent it is possible to detect cavities very early and begin treatment in the initial stages. This makes the treatment more conservative and rapid and also prevents any further damage from occurring. The chances of being able to retain the natural tooth are also increased.
