Study: Combining Toothpastes and Mouthrinses May Harm Enamel Structure

Posted: September 5, 2025
A study analyzed the effects of desensitizing and/or anti-erosive toothpastes combined with mouthrinses on enamel structure and dental pulp fibroblasts viability. The research assessed pH, titratable acidity, ion concentrations, enamel ultrastructure, and cell viability after exposure to various combinations. Results showed that the combination of toothpastes and mouthrinses may not enhance effectiveness and could potentially harm enamel and dental pulp cells. Enamel surface alterations and reduced calcium concentration were observed, along with decreased cell viability in most combinations. The study highlights the importance of considering the potential negative impacts of combining these oral care products on dental health.
