where the casing can thus be molded as a one piece element or readily cut or stamped from a sheet or blank of flexible plastic having a thickness of about 116 1 8 inch for example the bottom portion of each base member is secured to the substantially flat inner surface of each casing support section 36 38 support sections are sized such that a portion of each support section extends radially outward from the respective base member to form shelves 42 and 44 for receiving a label 46 indicating the date of loss of a tooth placed in a receptacle adjacent the label alternatively the casing can comprise or the shelf can include a layer of material suitable for print such as paper or equivalents thereof so that the date of loss can be marked directly on the tooth holder with no need for separate labels each shelf preferably has a width of about 1 4 to 1 2 inch so that a label having sufficient size for easy viewing can be placed thereon without detracting from the compactness of the tooth holder for storage the casing also is provided with a fastening mechanism for holding the upper and lower casing sections together when the holder is placed in its closed position for storage however any suitable fastening mechanism can be used as would be apparent to one of ordinary skill for example a mechanism that extends between the upper and lower sections of the casing and is provided with complementary snap fasteners as illustrated in the drawings such a mechanism can be provided by placing holes 48 50 in the upper and lower sections 36 38 for receiving string 52 which can then be tied to retain the holder closed as illustrated in fig6 it.
