Denture Maintenance
Quick fact
Soaking dentures in a denture cleaner overnight kills up to 99.9% of bacteria and fungi that cause infections like denture stomatitis.
Why this is interesting
Did you know that your dentures can be home to millions of bacteria if not cleaned properly? Just like natural teeth, they need daily care – but the wrong method can actually damage them.

Understanding Denture Maintenance
Denture maintenance is the routine of cleaning and storing removable false teeth. Without proper care, food particles and plaque accumulate, leading to stains, odors, and inflammation of the gums (stomatitis). The process typically involves brushing the dentures daily with a soft brush and non-abrasive cleanser to remove debris, then soaking them in a disinfectant solution to kill germs. Unlike natural teeth, dentures are porous and can absorb liquids, so they should be kept moist when not in use, but not in hot water which can warp them. Regular maintenance also includes inspecting for cracks or loose teeth and visiting a dentist for adjustments.
A deeper explanation
The primary mechanism of denture maintenance is twofold: mechanical removal of biofilm and chemical disinfection. Dentures collect a sticky film of plaque that harbors bacteria and fungi (especially Candida albicans). Brushing disrupts this biofilm, while soaking in effervescent tablets or alkaline peroxide solutions breaks down organic matter and releases oxygen to kill microbes. This prevents the breakdown of acrylic and metal components from acidic bacterial waste. Additionally, proper storage prevents drying out and warping. Understanding this balance between cleaning and preservation is vital because harsh abrasives can scratch the surface, creating hiding spots for bacteria, while inadequate cleaning leads to oral infections and bone loss. Thus, maintenance is not just about cleanliness but about preserving the structural integrity of the denture and the health of the underlying tissues.
