In most cases, your dentist will schedule a complimentary consultation to explain how the laser works and give you a demonstration. Next, the dentist will take X-rays to make a definitive diagnoses and determine the extent of the infection. When you return for your first LPTTM treatment, you'll receive a local anaesthetic to eliminate any possible discomfort. A general anaesthetic isn't necessary, because LASER PERIODONTAL THERAPYTM is much less traumatic. A tiny laser fiber (about the thickness of three hairs) is inserted between the tooth and the gum, and the infection is cleared away. The procedure is fast: It takes just two 2-hour sessions. Your dentist will treat one half of your mouth at each session...and you'll probably feel good enough to go right back to work afterwards.
