The invention is directed to a controlled-release solid composition for the oral cavity or "pharmaceutical oral patch" that adheres to hard dental surfaces, such as teeth and dentures, and releases an active pharmaceutical agent into the oral cavity. Release of the agent is for a predetermined period of time and at a predetermined sustained concentration. The site of action of the agent is local or systemic.
