Removing dentures nightly is essential for maintaining oral health and the appliance itself. This allows underlying gum tissues and bone structures to rest from the continuous pressure exerted throughout the day. This rest period reduces the risk of irritation, soreness, and inflammation, preventing conditions like denture stomatitis. Keeping the denture moist also prevents the acrylic material from drying out, which causes warping and cracking that compromises the appliance’s fit and longevity.
Preparing Dentures for Overnight Storage
The process begins with a thorough cleaning to remove the biological film, food debris, plaque, and bacteria that accumulate during wear. First, rinse the denture under lukewarm water to flush away loose particles. Then, gently brush all surfaces using a soft-bristled toothbrush or a specialized denture brush.
A non-abrasive cleaner is recommended, such as a mild hand soap or a denture-specific paste, since regular toothpaste is too abrasive. Abrasive particles create microscopic scratches on the acrylic surface, which become breeding grounds for bacteria and fungi. After brushing, the denture must be rinsed completely to ensure no cleaning agent residue remains before storage.
Choosing the Right Storage Solution
The most important rule for overnight storage is to keep the denture completely submerged in liquid. This prevents the acrylic from shrinking and losing its intended shape, maintaining the material’s integrity and comfortable fit. While plain, room-temperature water is an acceptable medium, it does not offer any cleaning benefits.
A more beneficial storage method involves using a specialized denture cleaning solution, such as effervescent tablets. These solutions contain antimicrobial agents, like alkaline peroxide, that break down plaque biofilms, kill harmful microorganisms, and eliminate odors while the denture soaks. The soaking container should be a dedicated, clean cup with a secure lid. Regardless of the solution used, the denture must be thoroughly rinsed with water before being placed back into the mouth to remove any chemical residue.
Storage Errors That Damage Dentures
Common mistakes can compromise the structural integrity and hygiene of the prosthetic appliance. Allowing the denture to dry out for extended periods is a major error, as this causes the acrylic to become brittle and warp, leading to an uncomfortable fit. Another damaging practice is using excessively hot or boiling water for cleaning or soaking, which permanently deforms the denture material.
Household chemicals should never be used as a storage or cleaning solution. Harsh agents like bleach or vinegar can weaken the denture’s acrylic, cause discoloration, or corrode any metal components present in partial dentures. The constant exposure to these substances can shorten the appliance’s lifespan.
