A Palatal Obturator is a prosthesis that can be used to close defects such as an opening in the roof of the mouth. They are similar to dental retainers. Openings in the hard and soft palate may affect speech or cause nasal regurgitation during feeding. A palatal obturator can improve speech, proper air flow, eating, reduce regurgitation. People who use palatal obturators must be monitored regularly by their prosthodontist to insure continued effectiveness and comfort of the prosthesis.
