Dentures play an important role in restoring the function and aesthetics of a natural smile for many patients. However, dentures require proper care to maintain their integrity and effectiveness. A central part of denture care is ensuring they always remain moist when not in use. Neglecting this simple guideline can lead to a range of issues that compromise both the dentures’ performance and the patient’s comfort. Here are the top three reasons why dentures must always remain moist.

Prevent Warping and Distortion

Dentists carefully craft dentures to match the unique contours of a patient’s mouth. However, when left to dry, dentures can lose their shape. The materials used to create most dentures are porous and flexible to accommodate daily wear, but when deprived of moisture, they are prone to shrinking or warping.

A distorted denture won’t fit properly, causing discomfort for the patient and requiring adjustments or replacements. Keeping dentures submerged in water or an appropriate soaking solution maintains their shape, ensuring they continue to fit precisely and function as intended.

Inhibit Bacterial Growth

Moisture plays a critical role in preventing bacteria buildup on dentures. A dry surface creates an ideal environment for bacteria to thrive, potentially leading to infections or unpleasant odors. Properly hydrating dentures and cleaning them daily reduces the risk of harmful bacterial accumulation. This is particularly important for older patients or those with compromised immune systems.

The use of approved soaking solutions can enhance sanitary maintenance by offering antiseptic properties in addition to keeping the dentures moist.

Maintain Comfort and Fit

Dryness is one of the most common denture problems, and it can cause friction against soft tissues, leading to soreness or irritation in the mouth. Furthermore, maintaining moisture helps ensure optimal adhesion between the denture and gums, which is critical for proper fit and stability. Patients should store their dentures in water or a suitable solution overnight to preserve their form and enhance daily comfort.

Dentures are an investment in a patient’s oral health, and moisture is key to protecting that investment. By emphasizing the reasons why dentures must always remain moist, dental professionals can ensure durability, hygiene, and comfort for their patients. Encourage best practices to help patients extend the life of their dentures while prioritizing their oral health and well-being.
