I had very deep pockets 5s and 6s and was referred for periodontal surgery. I went to Dr. Z because he is one of the few who offers LANAP. I wanted to try this less invasive/painful method that would not require use of cadaver or pig tissues. I am happy with the results. After 2 years, my pockets have greatly improved! Suffering from periodontal disease, I will always battle but I am no longer afraid of losing my teeth. The LANAP procedure was a positive experience that required a lot of diligent care, but left me free of cutting, stitches and pain. It took longer than the 1 year that I had thought it would for me to really see a drastic decrease in my pocket depth - but I am finally reaping the results through diligent care, under Dr. Z and my dentist.
