I had a dentist appointment today. No cavities, but I've never had a cavity. That's not my problem. I had some kind of periodontal thing, like extreme gingivitis. The bone around my jaw was degrading, so they had to cut back my gums, clean everything up, and even injected some material to act as bone replacement. They did my whole mouth, and then relocated some tissue to build up my gums in some places. They did a great job, one of the dental hygenists couldn't even tell the work had been done, she thought I was just normal. I don't have any recurrance either. The dentist said he should have taken before and after pics, I'd make a great advertisement.
