Periodontal refers to the bone and tissue health surrounding your teeth. Your periodontal status is determined following a complete examination and measuring the depth of the gums around your teeth. We also will note any changes in the tissue and check to see if your teeth are mobile. We will use x-rays to determine any bone loss. All this data will let us know the extent of any disease present. The periodontal types range from I to IV, with Type IV being the most involved.
