The old term for it is pyorrhea; now, we call it periodontal disease, referring to disease of the gum, bone, and supporting structures of the teeth.
If we determine that you have pockets (i.e. space between the tooth and gum greater than 3 mm), you will be evaluated for deep scale (also know as quadrant or quad scale). Deposits on the teeth under the gums can be removed by numbing a quarter of the mouth (e.g. upper right), and going under the gum to scrape off the deposits.
Depending on the result of the quad scale and your effectiveness at home care, we may discuss a referral to the periodontist.
