Objective: The aim of this study is to evaluate the tooth enamel erosion potential of energy drinks by analyzing pH, buffering capacity, and change in fluorescence for seven energy drinks. Method: Measurement of the pH and titratable acidity of energy drinks was achieved by stirring with a pH meter. The erosive effect of energy drinks on enamel was measured using quantitative light-induced fluorescence. The pH of energy drink “Bacchus” was the lowest at 2.49±0.02; “MONSTER (sugar free)” had the highest pH at 3.59±0.06. The titratable acidity 5.5 and 7.0 values of the energy drinks were 2.5–7.5 and 7.5–10.5, respectively. Results: As a result of the enamel fluorescence loss test using quantitative light-induced fluorescence, it was observed that erosion changed after 6 hours in the HOTSIX group. However, there was no change over time in the other groups. Conclusion: It is necessary to reduce the risk of dental erosion through proper education and management of the low acidity and buffering capacity of energy drinks.
