“Plaque is a sticky film that covers the teeth, and is composed of different types of bacteria and biological elements (such as calcium) found in your saliva,” said Brian Kantor, a dentist in New York. Typically found at the gumline, plaque can form for a number of reasons, either from eating starchy or sugary foods, not brushing every day or not flossing correctly. Most people can feel plaque when they run their tongue on their teeth, or if they scratch at the surface of their teeth with their nail and a yellow or white film comes off, said Rhonda Kalasho, a dentist and the CEO of TruGlo Modern Dental.
