Best dental clinic in Adambakkam | What Your Morning Coffee Is Really Doing to Your Teeth Your morning coffee may boost your energy, but it can stain and weaken your teeth. Coffee contains tannins that cause yellow and brown stains on enamel. Its acidity makes teeth more prone to sensitivity and decay. Adding sugar or creamers increases the risk of cavities. Sipping coffee all day is worse than finishing it quickly. Protect your smile—drink water after coffee and wait 30 mins before brushing. Regular dental cleaning and professional teeth whitening remove stains safely. At Dr. Akkshaya Dental and Aesthetics, Adambakkam, we help you keep your smile bright.
