A medication delivery tray provides a controlled release of medication to target dental strutures in the mouth, such as the teeth and/or gingiva, whil e maintaining a high concentration of the active chemical over an extended period of time. The medication delivery tray includes a dental tray having a base, a buccal wall and a lingual wall defining an inner surface. At least o ne medication reservoir is located on the dental tray. Each medication reservoi r includes a plurality of discrete support members projecting away from the medication reservoir to engage the dental structure of the patient. The support members are arranged to resist the flow of medication from the medication reservoir in a gingival direction. Each medication reservoir extends over the teeth and/or gum tissue of the patient when the medication delivery tray is placed over the patient's teeth.
