The cleaning process prevents teeth from becoming loose. The bone and gums surrounding the teeth help to keep them firmly in place. The gums and bones are infected as a result of tartar buildup around the teeth. This infection causes the bone and gum levels to recede, resulting in gaps between the teeth. If this tartar is not routinely removed (once every six months), teeth may become loose. The cleaning process will assist in removing tartar and halt the recession of the gums and bone.
