The safe, healthy choice is to not sleep with your partial denture in place. Sleeping with partial dentures is not recommended for a number of reasons. Partial dentures are designed to be cleaned outside the mouth – which also provides the opportunity to ensure no food particles are lodged under or around the partial. Proper oral care and keeping you partial denture clean is vital for the overall health of your gums. From a physical standpoint, your gums will benefit from the opportunity to rest and recover. Also, some patients may clench their teeth in their sleep. This pressure can cause damage to both natural teeth as well as dentures.
Over fifty patients were seen on the day I was. They were herded through the clinic, with their dentures made as fast as credit cards can be swiped, and regardless of quality. When mine were placed in my mouth, a definite elevation on the upper right was noticeable; the length of the right side teeth was pronouncedly shorter than the other side. I noticed this after I went to my car and called in the message. The hateful assistant **, left a recorded reply, "Your teeth were made the way they are supposed to be, so I don't know what your problem is." No mention of "We'll fix it any time." Certainly, no consideration for the pain of the patient was forthcoming.
