Hi, I'm Dr. Larry Klein. I'm a dentist here in St. Petersburg, Florida, and we're going to be talking about full mouth debridement. A lot of people don't know what that is. It really has to deal with the gums of the mouth, and periodontal issues. Gum disease, pyorrhea, periodontal problems, are all associated with plaque and tartar, that are either above the gum, or actually go below the gum, and if it goes below the gum, it actually causes bone loss, and that's what actually causes people to lose their teeth, due to gum disease, so the initial phase of gum disease, is called gingivitis, or inflamed gums, and basically what that is, is the tissue is still inflamed, but the bone underneath it is still ok, so in that case, a lot of times, the dentist, dental hygienist can perform this mouth debridement, full mouth debridement.
