Drink it through a straw - By drinking your coffee through a straw, you'll savor it by drinking slowly and bypassing direct contact with your teeth. Of course, hot beverages are not ideal for drinking through plastic straws, so invest in a reusable straw instead.
Try out one of these silicone straws made specifically for coffee and save your teeth while you save the planet from excessive plastic waste. Chug it - Instead of sipping on a straw, take the opposite approach and slam back your morning cup of java back.
By drinking it straight up with minimal contact with your teeth, you'll get your kick of caffeine without the worry of stains. Drink water – Aside from keeping you hydrated in between your cups of coffee (which is a diuretic after all and will make you go to the bathroom) drinking water will help you avoid stains. A couple of swigs here and there will help wash away any debris in between your teeth.
