I had an infection around my gum and Dr. Alder wanted to use a laser to treat this. I found this to be quite ridiculous. After visting two other periodontists, dental specialists, with ADA accredited , advanced training, I was educated and learned that this sort of suggested treatment is without any scientific basis. I needed gum surgery not expensive lights shone over my mouth. I can't believe this guy is for real. I am glad i went with a gum specialist. Dr. Alder needs to stop selling the snake oil and get with accepted methods of treatment.
