Lower dentures or mandibular dentures differ from upper dentures or maxillary dentures as lower dentures are kept in place with the tongue and cheeks compared to the upper denture which uses suction. The lower denture requires more practice to wear as the muscles need to be trained to keep the prosthesis in place. The best way to practice with a lower denture is to place the tongue right behind the lower front teeth. When the tongue places force on this one area, the denture stays seated against the bones on the ridge. The lower denture generally requires more practice to master compared to the upper denture as the tongue has to learn new muscle patterns to learn how to talk and to chew.
