Laser Cavity Detection/Diagnodent

What is DIAGNOdent and how does it work?

Diagnodent is a major breakthrough that allows the dentists to detect tooth decay that x-rays cannot see. We can now locate hidden decay in it’s earliest stage, and with treatment stop the spread of the disease before it destroys the tooth from within.

DIAGNOdent uses laser technology as an aid to detect and quantify hidden or sub-surface cavities by measuring laser fluorescence within the tooth structure.


The device operates at a wavelength of 655 nm. At this specific wavelength, clean healthy tooth structure exhibits little or no fluorescence, resulting in very low scale readings on the display.


Altered tooth substances and bacteria, including caries, will fluoresce. The DIAGNOdent will react with elevated scale readings on the display.


An audio tone allows the operator to hear changes in the scale values.


The DIAGNOdent is an extremely accurate, reliable and non-invasive method to aid in cavity detection.


Recently FDA approved, this amazing laser cavity finder instantly and accurately finds cavities in areas x-rays rarely see and the dental pick misses 76% of the time!
