Some strains of bacteria can cause the body to react by creating inflammation in an attempt to fight off the bacteria. Over time, the gum tissue begins to pull away from the roots of teeth, creating a space between the tooth and gum where more bacteria can grow. When this occurs, it usually causes bone loss around the teeth. These areas may have hard deposits of tartar that accumulate due to the deeper spaces where toothbrush bristles and floss don’t reach. If you have periodontal pockets showing active signs of inflammation, they may require periodontal treatment from your Lincoln dentist.
