On the 3rd, the British Daily Mail reported that Dr. Miles Madison, a dentist from California, USA, conducted an experiment on the effects of coffee, tea, cola, and red wine on tooth staining and shared the results on social media. The experiment showed that red wine caused more severe tooth staining than coffee or cola.

Dr. Madison soaked four extracted teeth in coffee, tea, cola, and red wine for 10 days and observed changes in the color of the tooth surface and interior. The results confirmed that the teeth soaked in red wine were stained the darkest. He said, "The entire tooth was stained. Everything, including the enamel and roots, was discolored. Red wine is the most damaging beverage for staining." Enamel refers to the surface of the tooth.

The teeth soaked in coffee turned yellow, with the root area turning a dark brown in particular. Dr. Madison explained that the tooth roots have lower mineral content, causing more severe staining than the enamel. The severity of tooth staining was in the order of ▲red wine ▲cola ▲coffee ▲tea.

On the other hand, the most severe corrosion occurred in the teeth soaked in cola. He explained, "Cola not only stained the teeth black but its acidic components dissolved parts of the enamel and root structure, creating small holes." This means cola has the potential to damage the tooth structure itself.

Dr. Madison warned against brushing teeth immediately after consuming acidic beverages like cola. He advised, "Brushing right after consuming highly acidic foods can damage weakened enamel. While typical staining is mainly a cosmetic issue, if teeth turn gray, nerve damage should be suspected." He also recommended drinking these beverages in moderation, rinsing with water immediately after drinking, and avoiding drinking for more than 15 minutes at a time.
