Do sterilising tablets damage oral appliances, including aligners, retainers, and night guards? (2023) - Dr. Jack Pinnar-Smith

Oral appliances, including aligners, retainers, and night guards, are crafted from medical-grade plastics or acrylics. Despite the durability of these materials, exposure to certain chemicals found in some sterilising tablets can induce degradation over time. This degradation process could lead to the structural weakening, discoloration, and warping of these appliances, which might affect their functionality and longevity.

Some sterilising tablets can contain potent chemicals such as chlorine-based compounds, bleach (sodium hypochlorite), and other harsh oxidizing agents. These chemicals can be aggressive against dental plastics, causing them to deteriorate over time. The damaging effects of these compounds are often exacerbated when used in conjunction with hot water, as many of these dental plastics are heat-sensitive and can warp or deform under high temperatures. Over time, repeated exposure to such conditions can gradually erode the structure of these appliances, leading to a higher likelihood of breakage and a shortened lifespan.

Zima Dental's sterilising tablets offer a safer alternative. Their tablets consist of ingredients such as sodium bicarbonate, sodium carbonate peroxide, and citric acid, which serve as gentle yet effective cleaning agents that don't degrade the material of dental appliances. The powerful cleaning effect of combining Zima Dental's tablets with the Dental pod doesn't require hot water, thereby also mitigating the risk of heat-induced damage. Zima Dental's tablets are designed to ensure thorough cleaning and sterilisation without causing harm to your oral appliance's structure. 

In conclusion, while some sterilising tablets contain chemicals that can damage dental appliances over time, Zima Dental's sterilising tablets have been carefully formulated to ensure effective cleaning without such harmful effects.
