PEORIA, Ill. -- A new dental breakthrough is reducing the need for drills and x-rays, leaving patients with pain free visits.
It's a new technology for dentists called the Spectra. It replaces all of the metal probes with light.
Different colors show the dentist how much bacteria there are on each tooth and if there are any cavities.
The device can also detect plaque and determine if the patient is brushing properly.
