The purpose of this paper is to share information about the digit-(thumb/finger) sucking behavior including how it begins; the biological, psychological and physiological connections; how it becomes perpetuated; problems related to prolonged sucking activity; guidelines for referral; and considerations for appropriate patient selection to enhance successful therapy. The basis for this information is a combination of published research and 24 years of clinical experience working with approximately 1500 individuals with sucking habits. Data compiled on 723 individuals will be presented.
