If dental implants cannot or should not be used, the adhesive bridge is mostly used for single tooth gaps. The dentition carrying the bridge should be free of caries, cavities and/or fillings. There is only an age limit for two-winged and splinted adhesive bridges in adolescents who are waiting for the eruption of their permanent teeth. Adhesive bridges, which are not used to splint two teeth together, can be used for children and adolescents. Maryland dental bridges are mainly used in adolescents if the teeth are missing congenitally or due to accidents or if a gap has formed after orthodontic treatment. In adults, the most common cause of tooth loss is due to gum disease or a failing root canal treatment.
