Dentures replace missing teeth and surrounding tissue, restoring function and appearance. These appliances are designed to be worn during the day to facilitate speaking and chewing. Dental professionals agree that dentures should be removed nightly as a fundamental part of maintaining oral health. Failing to remove the prosthetic device before sleeping can introduce physiological and pathological issues. This nightly practice is necessary for the long-term integrity of the oral tissues and the denture itself.
Why Dentures Must Be Removed at Night
Continuous denture wear creates a constant barrier between the acrylic base and the underlying oral mucosa. This coverage prevents the soft tissues from receiving a necessary period of rest and recovery from mechanical pressure. Gum tissues require this break to restore normal blood circulation and allow for proper oxygenation. When the tissue is covered, it traps moisture and creates a low-oxygen environment ideal for microorganism proliferation. Removing the device also allows saliva to perform its cleansing function without obstruction.
Specific Oral Health Issues from Continuous Wear
The pathological outcome most strongly linked to chronic nighttime wear is Denture Stomatitis, a common inflammatory condition affecting the palate. This condition is characterized by tissue redness and inflammation, often affecting up to 80% of wearers. The warm, moist environment under the denture encourages the overgrowth of the fungus Candida albicans, leading to oral candidiasis or thrush. Continuous pressure also accelerates Alveolar Bone Resorption, the progressive shrinkage of the jawbone ridge that supports the denture. This bone loss causes the denture to lose its stable fit, and studies link continuous wear to an increased risk of aspiration pneumonia.
Proper Cleaning and Storage Protocols
Nightly removal must be paired with a rigorous cleaning and storage routine to ensure both hygiene and material integrity. The denture should be thoroughly cleaned immediately upon removal using a soft-bristled brush and a non-abrasive cleanser, such as mild liquid soap or a specialized paste. Regular toothpaste must be avoided because its abrasive particles can scratch the acrylic surface, creating microscopic niches where bacteria and fungi can accumulate. After cleaning the prosthetic, the oral tissues must also be addressed; the gums, tongue, and any remaining natural teeth should be gently brushed with a separate soft toothbrush to remove accumulated plaque and stimulate circulation. For storage, the denture must be kept moist by immersing it overnight in clean water or a specific cleaning solution to prevent warping; never use hot water, and rinse chemical cleansers thoroughly before reinsertion.
