Abstract
A flavored toothpaste composition is bonded to the bristles of a disposable toothbrush by a process which involves the chemical grafting and polymerizing of selected monomers and prepolymers to the bristles via a free radical mechanism. This process locks in the flavor until the product can be utilized. When the toothpaste is brought into contact with an aqueous medium, such as saliva in the oral cavity, the toothpaste dissolves thereby releasing the desired flavor to the teeth and oral cavity.
