With an aging population, the global tooth filling materials market is expected to grow to $2.6 billion by 2027. Resin composite fillings are widely used, offering advantages of color matching and having no mercury content, unlike traditional amalgam. However, a major drawback to their use is that the bonding integrity at the interface between the restoration and the dentin and enamel may become compromised due to stress and exposure to the oral environment. This compromises the margin integrity and allows penetration of bacteria, which can lead to secondary caries, and ultimately, failure of the restoration. Problems with existing potential additives include toxicity, compromised mechanical properties, and questionable long-term effectiveness.
