Laser Cavity Detection in Fargo ND & Moorhead MN

Early Cavity Detection with
The Canary System®

What is The Canary System™?

The Canary System™ is a device for the early detection and monitoring of tooth decay. It can detect decay on smooth enamel surfaces, root surfaces, biting surfaces, between teeth and around existing amalgam or composite fillings. It is a pain-free, safe and non-invasive early detection system built on years of thorough research.

Advanced Laser Cavity Detection

An independent study found The Canary System to exhibit a 97% sensitivity. This level of accuracy can be attributed to The Canary System because it measures the crystalline structure of the tooth and not bacteria.
The Canary System is the winner of the 2010 National Instruments’ Graphical System Design and Achievement Award in the Medical Device Category

A Device for the Early Detection and Monitoring of Tooth Decay

How does The Canary System work?

The Canary uses a low-power, pulsating laser light to scan teeth for the presence of dental caries or tooth decay. The laser light is absorbed by the tooth and two phenomena are observed: the laser light is converted into luminescence and there is a release of heat. This heat will not harm the tooth but gives us important information about the tooth up to a depth of 5 mm below the surface. Simultaneous measurement of the reflected heat and light provides us with information on the presence and extent of tooth decay below the tooth surface before being detected by dental radiographs.

What happens when carious lesions are detected?

Early detection of dental caries allows decay to be halted or reversed using remineralization therapies. Therapies such as the application of fluoride can repair teeth by reconstituting the minerals into decayed areas.

What are the benefits of The Canary System™ over its competitors?


  • Identify and monitor tooth decay without the need for dental x-rays
  • Detect decay on all tooth surfaces including between teeth (interproximal areas)
  • Detect decay in between teeth at an earlier stage than the traditional dental x-ray
  • Detect decay as small as 50 microns (20 times smaller than a millimeter)
  • Examine teeth for decay as deep as 5 millimeters below the tooth surface
  • Offer a safe, non-invasive, painless and quick experience

Will earlier caries detection and remineralization therapy mean less "drilling and filling"?

Yes. With The Canary System, Quantum Dental Technologies provides the technology to detect and monitor these early lesions well before "drilling and filling" are required. Remineralization works best if there is some intact enamel. Once the decay has broken through the enamel shell a filling is required.

What is the research behind the technology?

The Canary was developed at the University of Toronto under the direction of Dr. Andreas Mandelis in collaboration with Dr. Stephen Abrams, a practicing dental clinician. Since 1999, the research group has published over 40 articles and abstracts in peer-reviewed dental and medical journals. They have also presented their findings at over 30 international conferences.

The Canary Dental Caries Detection System has been proven superior to the standard diagnostic tests for tooth decay. Our research has shown that the Canary System offers greater sensitivity and specificity than dental x-rays in detecting early areas of tooth decay.

What's wrong with current diagnostic technologies?

Current diagnostic technologies limit the ability of dentists to detect and monitor the early stages of tooth decay. The standard for detecting tooth decay is visual inspection, manual probing and X-rays, all of which are of little use if the decayed area is very small (or below the surface). Typically, 40 - 60 percent of the tooth surface in question needs to be demineralized before it is seen on a dental X-ray.

The Canary Dental Caries Detection System uses laser light to detect tiny lesions in teeth without patient exposure to radiation. It is pain-free, safe, non-invasive and a more sensitive device for the detection of tooth decay.
