One way we plan to grow our diagnostic technology here at Cadena Dentistry is the Spectra Vision Caries Detector. This device emits a special blue-violet light that easily identifies cavities, even if they’re very small or obscured. Cavities that could have been easily missed during a manual exam are defined and clear under the light of the Spectra Vision Caries Detector. This means less poking and prodding during a checkup, and more comprehensive, proactive care.
