As bad of a habit it is, I normally start my day with a tall skinny vanilla latte from Starbucks. Hey- at least it wakes you up and boosts your metabolism. Plus, Dr. Oz says coffee is a anti-oxidant. The bad thing....it stains your teeth. Yes, now-a-days you can get your teeth whitened in the mall (Tysons Corner has EVERYTHING), but why not avoid things that will make you have to spend $$ instead?
To avoid coffee from staining your pearly whites, use a straw to sip it. Yes, I know it may look funny drinking hot coffee from a straw, but it really will cut back on the amount of coffee that touches your teeth. The same goes for dark sodas- they too can stain your teeth and hurt the enamel on them.
So, pick up a straw when drinking anything dark to keep your smile bright! ;)
