Laser dentistry refers to any dental procedures that involve the use of a laser. Recent advances in laser technology have allowed many dentists to offer laser treatment. During a dental laser treatment a laser device that transmits a highly concentrated beam of light is used to treat tooth decay, enamel, and gum tissue. Common laser dentistry procedures include oral surgery or periodontal treatment (gum disease, gingivitis) often referred to as laser periodontics.

It has been shown that dental lasers are safe for both children and adults. In addition, the Food and Drug Administration (FDA) has approved several types of dentistry lasers for use on adults and children. Many of the lasers for dentistry are similar or identical in design to other medical lasers that have been used successfully for years in the specialties of ophthalmology, neurosurgery, Ear/Nose/Throat (ENT), and dermatology.

Advantages of Laser Dentistry include:

• Minimal or no anesthesia
• Minimal bleeding
• More controlled swelling
• Reduced postoperative infection/discomfort
• Less chance of infection
• Reduced time in dentist's office
• Less pain
• No noise (like a traditional dentist's drill) 
• Preservation of tooth structure
• A more sterilized environment (dental laser kills bacteria)
• For the treatment of canker sore and herpes lesions,
• the laser can actually decrease the pain experienced by these sores.
