If Your Teeth Get Fuzzy After Lunch...
Use "detergent" or add "water" if you don't brush after every meal, says Linda Niessen, DMD, clinical professor at Baylor College of Dentistry-Texas A&M University. "Detergents" are fibrous foods such as celery, apples and carrots, which scrub away debris as you chew, she says. "Water" is saliva, which neutralizes acids and washes away food particles—and you make more of it when chewing sugar-free gum. But don't postpone brushing and flossing for too long. "Plaque must be thoroughly removed every 24 hours," says Niessen. (To put in the requisite two minutes, she recommends the timer app Brush DJ.)
