VELscope is a leading early detection technology. The handheld scope uses tissue fluorescence visualization to detect problems in the mouth months or years before it would become visible to the naked eye. Tissue fluorescence happens when fluorophores (natural chemical compounds) in the tissue of the mouth are excited by light. When this happens, the mouth tissue naturally emits its own light in response.Traditional scope tools use basic reflected light to examine the mouth. VELscopes utilize a specialized blue light that activates the fluorophores in the tissue of the mouth, revealing detail even at a cellular level. VELscope is an incredible step in preventive dentistry.
