Palatal Obturatosr are prostheses used to address and close defects such as an opening in the roof of the mouth and are mostly similar to dental retainers. A palatal obturator helps improve speech, proper air flow, eating, reduce regurgitation as openings in the hard and soft palate might affect speech or cause nasal regurgitation during feeding. 

People that use palatal obturators have to be monitored regularly to ensure continued effectiveness and comfort of the prosthesis.
