While getting my teeth cleaned the other day, my dentist asked me if I brush twice a day. "Of course. Ever since I was a kid," was my response. But she said that I should bring a toothbrush and toothpaste to work and brush after every meal, three times a day. She added that if I had time, I should brush after snacks and beverages like coffee, too. I know that means a lot of time spent at the bathroom sink, but if you have issues with cavities or bad breath, give my dentist's advice a try. Be sure to use a toothbrush with soft bristles and brush in a circular motion so you don't irritate your gums.
