Best dentist in Adambakkam | Coffee, Tea & Wine: Top Stain-Causing Drinks and How to Prevent Them Love coffee, tea, or red wine? These favorites are also the biggest culprits of teeth staining. They contain tannins and acids that cling to enamel, leaving yellow or brown stains over time. Frequent sipping makes stains worse and can also weaken enamel. Adding sugar or sweeteners increases the risk of cavities. But you don’t need to give them up! ✅ Drink water right after, or use a straw when possible. ✅ Rinse, and wait 30 minutes before brushing to protect enamel. ✅ Schedule professional cleaning or teeth whitening for a brighter smile. At Dr. Akkshaya Dental and Aesthetics, Adambakkam, we help restore your natural shine safely.
