You don't have to be rich, or a movie star, to flash a bright smile.
Teeth whitening is one of today's fastest-growing cosmetic procedures.
Several types of inexpensive home whitening products promise to transform any dingy grin into a gleaming smile. But there are some potential problems that could turn that smile upside down. Despite good hygiene, over time, aging, nicotine, coffee and food stains can dim anyone's smile. Instead, a tray or strip containing bleaching solution is applied directly to your teeth. With or without your dentist's help, there are side effects.
