Image Number 3 for United States Patent #5683421.
An improved teething apparatus that mechanically aids in massaging and cleaning the gums and teeth of an infant. The apparatus has a flexible outer shell which covers a relatively rigid inner member. Mounted to the inner member is a motor and at least one switch which actuates the motor thereby generating vibrational forces which are transmitted throughout the inner member and outer shell. The vibrational forces soothe sore gums and facilitate in the process of breaking the cusp tips of new teeth through the gum line and aid in keeping the teeth and gum line clean.
