Technology is changing the was in which dentistry is performed everyday. One example is how lasers are being used in dentistry from everything from preparing teeth for fillings, surgical treatments on soft tissue, and treatment of periodontal disease. Lasers create energy in the form of light, this energy can be very highly controlled which allows for cutting tissue with minimal tissue damage, bleeding, pain, and post operative complications. Often laser procedures can be performed without anesthesia. Laser treated tissues heal quickly and patients enjoy not having to be numb for most procedures. As technology improves lasers will find even more applications in dentistry that improve the lives of patients and doctors.
