My Precious Kid PRODUCT- Safe Kids Haven Tooth Prints Toothprints is a patented, arch-shaped thermoplastic wafer. When your child bites into the softened wafer, it records individual tooth characteristics, tooth position within the arch and the upper to lower jaw relationship plus collects DNA in saliva- all important information for identification. You'll then write your child's name on the zippered plastic bag provided and keep it at home in a safe place. Do one impressions at age 3, age 8 and age 12.
