Spectra™ is the latest advancement in cavity detection. Spectra™ is a small hand-held device that emits a high energy, violet-blue light. When projected on the tooth surface the light waves causes healthy tooth enamel to fluoresce green and compromised enamel to fluoresce red. This technology allows us to detect decay at a very early stage, before it is visible to the naked eye, and before it has a chance to cause significant tooth damage. This technology, used with tradtional methods can save tooth structure.
