A Canadian diagnostic device company, revealed its breakthrough technology which detects and monitors the early onset of tooth decay without the need for dental x-rays. It reduces the number of invasive and painful procedures, and encourages better oral health. They introduced  Dental Caries Detection System, as The Canary System.

The Canary System uses a handheld laser that send out a low-power light to examine tooth surfaces. When laser light is shone onto the tooth, the system measures the level of glow (luminescence) and heat released from the tooth. Laser light interacts differently with healthy teeth than with decayed teeth. By varying the pulse of the laser beam, a depth profile of the tooth can be created to permit detection of decay as deep as 5mm from the tooth surface and as small as 50 microns in size (20 times smaller than a millimeter). With The Canary System, the dentist is able to identify areas of decay much earlier than with current methods.

The Canary System can scan for caries on smooth enamel surfaces, root surfaces, biting surfaces, between teeth, and around existing fillings. Current methods are not as sensitive in detecting early decay in these areas.
