Decay Detection Technology

Posted in Laser Dentistry

Laser cavity detection uses state of the art light and sound wave technology to identify tooth decay earlier on than has ever been possible. Traditionally, decay in tooth enamel has only been able to be diagnosed through visual, tactile and radiographic inspection. Even when decay is diagnosed early on, these methods do not catch tooth decay as early as the technology that is used in laser decay detection. In fact, x-rays only show tooth decay that has already prominently developed inside of the tooth enamel and cannot show smaller areas of decay until they have progressed to a certain point.

By using laser technology, cavities can be treated in a less invasive, less expensive, and more comfortable manner that preserves as much natural tooth structure as feasibly possible. In some cases a dental filling may not even be needed, but rather simple air abrasion followed by a protective sealant placed over the weakening area.

Devices like the DIAGNOdent provide 90% accuracy in identifying weakened tooth enamel deep within natural grooves of the teeth long before an x-ray or instrumentation can. It works by light and sound waves being emitted into the tooth through the high tech hand piece. Feedback is reflected back into the machine, which determine how weak the suspected tooth enamel actually is. This reading is displayed as a number on the device that ranks the density of the area against healthy tooth enamel on other teeth in the same patient.

The ADA and FDA have both approved laser decay detection as an effective screening method for dentists to provide their patients with minimally invasive, early dental care. Ask your dentist or hygienist about laser cavity detection for you and your child to help you catch decay before it’s even visible.
