An open contact is a term used in dentistry to describe the space between adjacent teeth when the teeth are neither touching nor a sufficient distance from each other to potentially allow the space to naturally remain free of debris. Open contacts can exist naturally, such as when teeth erupt into a nonideal occlusion or when they shift as a result of tooth loss. They are also frequently produced as a result of inadequately contoured dental restorations.〔(Section 51 - Restorative Contours )〕 An open contact may lead to a phenomenon termed food packing/food impaction, which can be a cause of pain. ==References==
