Laser Technology for Dental Fillings

Painless laser system used to prepare teeth for a filling by destroying germ cells.

Dental lasers are a relatively new dental technology used to prepare the tooth structure for a filling or other restorative material. Dental lasers are quiet, non-invasive, and highly accurate, making them very effective in cavity preparations.

How Laser Cavity Preparation Works

In laser cavity preparation, dentists use lasers to clear away decayed tooth material. The laser also prepares the enamel and dentine of the tooth for better bonding with the restorative materials. Once the area has been cleaned out, a filling or other dental restoration can be placed to seal the area.

An important feature of laser treatments for cavity preparations is the ability of lasers to destroy bacteria. This prevents further tooth decay from occurring.

Laser Dentistry

Laser treatments can be used for a wide variety of dental procedures. In addition to cavity preparation, dentists use lasers for teeth whitening, treatment for sensitive teeth, and to prepare for restorative procedures such as root canals. Lasers can also be used on primary teeth (baby teeth).

How Dental Lasers Work

The word “laser” stands for “light amplification by stimulated emission of radiation.” A dental laser uses highly concentrated beams of light to affect the hard and soft tissues of the mouth.

Different types of lasers can use various wavelengths of light to affect different types of tissues in distinct ways. Soft tissue lasers (also known as dental diode lasers) are able to shape and remove the soft tissue of the mouth. Hard tissue lasers can help dentists clear out decayed areas of teeth and the “smear” layer of tooth roots and disinfect root canals.

Three common types of lasers used in dentistry include the Nd:YAG Laser, carbon dioxide lasers, and diode lasers.
