Key Developments in the 1990s:

• FDA approval of lasers for dental procedures.
• Introduction of WaterLase technology by Biolase.
• Expansion of laser dentistry applications.

FDA Approval of Dental Lasers

The FDA's approval of lasers for dental procedures in the 1990s opened the door for the widespread use of laser technology in dental practices. Dentists could now use lasers for soft tissue procedures such as gum surgeries, biopsies, and frenectomies. These early lasers made dental treatments less invasive and more comfortable for patients. However, their use was still limited to soft tissues.

Introduction of WaterLase Technology

One of the most significant innovations during this period was Biolase's development of WaterLase technology. WaterLase combined laser energy with a water spray, allowing the laser to cut through hard and soft tissues. This was a major step forward in making laser dentistry more versatile and effective for a wider range of procedures, including cavity preparation and root canals.

Expansion of Laser Dentistry Applications

As laser technology improved, its applications in dentistry expanded. Dentists began using lasers for more procedures, including cosmetic treatments and restorative work. Although early lasers had limitations, their ability to provide minimally invasive treatments made them a valuable tool in dental care. Now, laser dentistry compares favorably to traditional methods.
