No cavitat machine. He did that cone beam xray. Diagnosed them on all sides of my mouth but the main one is UL. I'm going for a second opinion Thursday. I don't think that dentist has the cavitat machine either. They just treat them w/ ozone is what they said. The first doctor said its a big surgery and I'd be in recovery for 3 weeks. It just scares me since I've never heard of it. Thanks for the link I will check it out.
