A lingual arch space maintainer or TPA is a dental appliance that is placed around the molars to prevent them from moving forward and blocking the space for permanent teeth that are yet to come in. This device is used in cases where baby teeth have been lost prematurely or when the lower teeth are slightly crowded. By keeping the molars in place, the lingual arch helps to maintain proper spacing and alignment of the teeth.
