An apparatus and method is disclosed for treating a tooth with an active agent such as a tooth whitening agent comprising a stint having an internal region defined by an internal surface. A plurality of indentations are formed in the internal surface for retaining the active agent to maintain the active agent in contact with the tooth when the stint is applied upon the tooth. The stint is molded from a sheet of plastic material with the indentations being formed by an abrading process such as abrasive blasting or the like.
