A patient has a six-millimeter pocket on the mesial of tooth # 19. Tooth # 20 was removed 10 years ago due to an endodontic lesion. As a result of not replacing tooth #20, tooth #19 has tipped forward mesially to contact tooth #21. Scaling and root planing will eliminate the six-millimeter pocket on the mesial surface on tooth #19.
