Are Zima Dental's sterilising tablets compatible with cobalt chromium dental appliances? (2025) - Dr. Jack Pinnar-Smith

"Cobalt chromium" refers to a type of dental alloy that's commonly used in the manufacturing of various dental appliances. It's favoured because of its strength, durability, and corrosion resistance. It's also hypoallergenic, which makes it a good choice for patients with metal sensitivities.

When cleaning your cobalt chromium appliance, it's important to be wary of certain chemicals: 

1. Abrasive Substances: Abrasive substances could potentially scratch or wear down cobalt chromium over time. If a cleaning product seems to have a gritty texture, it might be best to avoid using it on cobalt chromium appliances.
2. Strong Acids or Bases: Strong acids or bases might potentially cause issues, although this is unlikely with commercial cleaning products intended for dental appliances.
3. Chlorine Bleach: Sodium hypochlorite (commonly known as bleach) can cause corrosion of some metals, though cobalt chromium is usually resistant. Nonetheless, it is typically recommended to avoid using bleach on any dental appliances.
4. Long-term Soaking: While cobalt chromium is resistant to most cleaners, long-term soaking (like leaving the appliance in the solution overnight) may not be recommended because it could potentially lead to surface changes or discoloration.

Zima Dental's sterilising tablets contain a mix of cleaning agents, fillers, and flavourings that are all compatible with cobalt chromium dental appliances. The ingredients, including sodium bicarbonate, sodium carbonate peroxide, and citric acid, provide effective cleaning without causing harmful reactions or damaging the alloy. This ensures your cobalt chromium appliance remains in optimal condition while maintaining its cleanliness and longevity.
