Will Zima's tablets bleach my dentures? (2026) - Dr. Jack Pinnar-Smith

Zima's Ultrasonic Boosting Tablets are an expert blend of ingredients, carefully formulated to support effective cleaning of dentures without the risk of bleaching or discolouration over time.

The key ingredients work together to create a gentle, non-bleaching cleaning process that helps remove food residues, plaque and buildup from the surface of your appliance.

Some other brands of denture cleaning tablets contain harsh chemicals (such as chlorine bleach or hypochlorite salts), which may contribute to bleaching or discolouration over time. These substances are strong chemical cleaning agents and stain removers, but their overuse can lead to gradual bleaching of the dentures, altering their appearance and even causing them to become brittle. Some tablets may also contain high concentrations of peroxides, such as hydrogen peroxide, which can also lead to discolouration of the dentures when used frequently.
