A dental teaching toy for children having structure including an artificial upper artificial gums, artificial baby teeth, and artificial adult molars (for which there are no earlier and corresponding baby teeth). Also included is at least one removable artificial baby tooth having a crown, and an artificial adult tooth having a crown and a root, the adult tooth positioned within a channel in the artificial gum wherein the removable baby tooth is removably attached to the crown of the adult tooth. The removable baby tooth can be manually replaced by the adult tooth by placing a finger through a proximal opening in the artificial gum and pushing on the root of the adult tooth, thereby pushing the crown of the adult tooth through a distal opening in the gum, thereby pushing the baby tooth out from the gum and can be removably detached from the adult tooth. The baby tooth can be removably attached back in place on the gum by pushing the crown of the baby tooth against the crown of the adult tooth and pushing the adult tooth back into the channel within the gum.
A dental teaching toy for children having an artificial upper gum and an artificial lower gum, the artificial gums having artificial baby teeth and artificial adult teeth, wherein there is at least one artificial baby tooth connected to the toy in its natural position relative to the corresponding gum, means for removing the artificial baby tooth from the toy, a corresponding artificial adult tooth located within a channel in the gum, the artificial gum also having a proximal opening that is located adjacent to the bottom of the root of the artificial adult tooth, and a distal opening in the gum that is located near the connection between the baby tooth and the toy, the proximal opening being large enough to accept a projection that can push the crown of the adult tooth through the distal opening, whereby the artificial baby tooth can be manually interchanged with the artificial adult tooth and thus demonstrate the replacement of baby teeth by adult teeth.
