Dentures are prosthetic devices designed to restore the function and appearance of missing teeth. Their longevity depends heavily on routine care, and proper nightly storage is essential for maintaining the appliance’s integrity and the health of underlying oral tissues. An effective nighttime routine ensures the denture material retains its correct shape and prevents the buildup of microorganisms. Understanding proper storage leads to a more comfortable fit and a healthier mouth.
Why Dentures Need Nightly Removal
Wearing dentures constantly can lead to complications for the oral mucosa. Continuous pressure restricts the natural flow of blood to the underlying gum tissue and bone ridges. Removing them at night allows these soft tissues to rest, supporting better circulation necessary for tissue recovery and health.
Resting the gums helps reduce the risk of developing pressure-related sores or irritation that can affect the denture’s fit. The warm, moist environment trapped beneath the appliance is a breeding ground for bacteria and fungi, such as Candida species. Prolonged wear increases the risk of developing denture stomatitis, a fungal infection.
Taking dentures out for six to eight hours overnight limits microorganism proliferation, contributing to better oral hygiene and reducing bad breath. This nightly rest period is an opportunity for the mouth to naturally cleanse itself, especially since saliva production decreases during sleep. Consistent removal also helps slow down bone resorption caused by denture pressure.
Proper Cleaning Before Storage
Before storage, dentures must undergo a thorough physical cleaning to remove food debris, plaque, and biofilm. Begin by rinsing the appliance under running water to dislodge loose particles remaining from the day. This initial rinse is important because it clears the way for a more effective brushing process.
Handle the dentures carefully during cleaning, ideally over a folded towel or a basin filled with water, to prevent accidental breakage if dropped. Use a specialized soft-bristled denture brush to gently scrub all surfaces, including the inner side that contacts the gums and the grooves where adhesive may have been used.
Regular toothpaste should not be used because its abrasive compounds can create microscopic scratches on the acrylic surface. These scratches harbor bacteria and can lead to discoloration and odor over time. Instead, use a non-abrasive denture cleaning paste or a mild hand soap. After brushing, rinse the dentures thoroughly under water to ensure all cleaning residue is removed before they are placed in their overnight soak.
The Ideal Overnight Storage Environment
The primary rule for overnight storage is that dentures must remain moist to prevent the acrylic material from drying out, which can cause warping or cracking and compromise the fit. Never expose dentures to hot or boiling water, as the high temperature will cause the resin to distort irreversibly. Use cool or lukewarm water for all cleaning and soaking purposes.
Dentures can be submerged in clean tap water or a dedicated denture-soaking solution overnight. Soaking solutions, often in the form of tablets dissolved in water, contain cleansing agents that help disinfect the appliance and remove stains missed by brushing. If using a cleaning solution, always follow the manufacturer’s directions regarding the soaking time to avoid damaging the denture.
For dentures that contain metal components, such as partial dentures with clasps, consult a dental professional about the best storage medium. Some cleaning solutions contain ingredients, like chlorine, that can tarnish or corrode metal over time. A dedicated, clearly labeled container with a secure lid should be used to protect the dentures from dust and accidental contamination. This container should be kept in a safe place at room temperature, away from pets, children, and any source of high heat. Before reinserting the dentures in the morning, rinse them thoroughly to remove any residual cleaner that could irritate the mouth.
