Abstract

Abstract An anatomically contoured post-extraction pad made by compressing a piece of absorbent material to form an absorbent portion surrounded by a marginal portion of substantially greater density. The marginal portion is cut to generally complement facial contours of teeth adjacent an alveolus or tooth socket, whereby the pad is retained by and between the aforesaid teeth with its absorbent portion disposed in the alveolus. Assemblies of series connected pads may be provided for use in multiple extraction.
