A gum-like device is designed for the controlled and continued delivery of rifaximin, without producing the usually intense red coloration, for the resolution of the infections and the reduction of the inflammation in the oral cavity and in the laryngo-pharyngeal one. The device also protects either the gum or the dental apparatus from acute infections, from the infiltration and the stagnation of the food, and fights chronic infections such as in the periodontal pockets. Moreover, the device can be used to protect the gum from the traumatizing collision that the food exercises during the mastication.
