I'm sure you've heard (especially if you've had your teeth whitened) that dark liquids like red wine and cola can stain your teeth. True. You want your teeth to be white and "white" wine should be a good, non-staining choice, right? False.
A study at New York University College of Dentistry revealed that white wine may actually make teeth more susceptible to stains (if you drink it - or soak cow teeth in it for an hour, as they did in the study). White wine contains acids that can create ridges in the teeth which allow staining agents to get deeper into the teeth.
Of course, red wine is still worse than white wine on the staining scale, especially if you drink it second.
I am currently visiting New York City. My wife broke a crown, so we needed to find a dentist for her. If only we knew a way to find a great dentist. Oh, wait... I called 1-800-DENTIST, got referred to a great dentist and she was able to be seen right away. To paraphrase Mastercard, the phone call was free and the results were priceless.
Thankfully, my hair is all my own. However, I feel another paraphrase coming on. This time, it is Sy Sperling: I'm not only the CEO of 1-800-DENTIST, but I'm also a client.
