TPO Ban: From Nail Polish to Potential Dental Device Restrictions in Portugal

A chemical banned in gel nail polish across the EU is reportedly still used in some dental procedures in Portugal, sparking concerns about wider regulatory action.
What Happened?
The chemical, Tris(2,4-di-tert-butylphenyl) phosphate (TPO), has been banned in cosmetic products, specifically gel nail polishes, throughout the European Union due to concerns about its potential endocrine-disrupting properties and reproductive toxicity. However, euronews reported on September 26, 2025, that TPO continues to be used in certain dental materials in Portugal, specifically in dental cements and composites.
Why is TPO Used in Dentistry?
TPO acts as a plasticizer and stabilizer in dental materials. it improves the flexibility and durability of dental cements and composites, making them easier to work wiht and potentially extending their lifespan. Dentists in Portugal argue that suitable alternatives are not currently available that offer the same performance characteristics, particularly in specific applications like certain types of fillings and orthodontic adhesives.
What are the Concerns?
The primary concern revolves around the potential health risks associated with TPO exposure. Studies have indicated that TPO may act as an endocrine disruptor, interfering with hormone function. This can potentially lead to adverse effects on reproductive health, growth, and other bodily systems. While the levels of exposure from dental materials are generally considered low,the long-term effects are not fully understood. The EU ban on TPO in cosmetics reflects a precautionary approach to protecting public health.
