Introduction: An increase in the demand for aesthetic restorative procedures has brought about a shift in the dental practice paradigm. It is necessary to assess the impact of the consumption of carbonated soft drinks and other beverages on the longevity of restorations. Materials and Method: The 48 samples from each group were divided into three subgroups based on the duration of exposure to acidic beverages (no exposure, 1 day, and 7 days). These subgroups were: Group 1- Polo fil NHT, Group 2- Omni Chroma, and Group 3- Neo Spectra ST. The surface microhardness of the materials was evaluated before and after exposure. Results: The study found that the Polo fil NHT group and the Neo Spectra ST group had the highest and lowest surface microhardness values, respectively, after exposure to an acidic medium for one day and seven days in artificial saliva. The difference between these values was statistically significant. Based on the study's parameters, Polo fil NHT was found to perform better than Omni Chroma and Neo Spectra ST when exposed to acidic beverages. Conclusion: Polo fil NHT was the most resistant to the effects of acidic beverages among the tested materials
