DIAGNOdent
Laser-assisted cavity detection that identifies decay earlier than visual examination alone, allowing more conservative treatment.
DIAGNOdent uses laser fluorescence to measure the condition of a tooth's structure, including within grooves that are difficult to assess visually or radiographically.
Finding decay at an earlier stage means smaller restorations, more preserved tooth structure, and fewer surprises between visits.
What it means for you
Earlier detection
Identifies decay in early stages, when treatment is simplest.
No radiation
The reading is taken with light, not X-rays.
Painless
The tip passes over the tooth surface without any pressure or discomfort.
Objective readings
Numeric readings can be compared over time to monitor a questionable area.
In the chair
- The scan takes only a few moments during your routine exam.
- Readings are discussed with you alongside the rest of the examination.
- Some areas may be monitored rather than treated immediately.
Questions
How does DIAGNOdent find cavities?
It directs harmless laser light at the tooth and measures the fluorescence that returns. Decayed tooth structure fluoresces differently from healthy structure, which produces a reading the dentist interprets alongside the clinical examination.
Does it replace X-rays?
No. It complements them. Radiographs still show areas between teeth and below the gumline that a surface scan cannot assess.
