The Teethifier
The Teethifier is a new kind of pacifier that reaches the sore gums in the back of the mouth. It looks like something that would work pretty well for sore gums, and something the baby will instantly know how to use, as it still looks like the familiar pacifier.
The Teethifier costs $4.50 and can be bought at Kid Gear.

This seems like a very useful product and the cost is quite good! Thanks for sharing..
