What exactly is dental plaque?
Dental plaque is a soft, sticky film that constantly forms on your teeth. It is made up of bacteria, saliva, and tiny food particles that remain in your mouth after eating or drinking.Plaque is usually colorless or pale yellow, which makes it hard to notice. But just because you can’t see it doesn’t mean it isn’t there. It sticks tightly to the surface of teeth and especially around the gum line.If plaque is not removed regularly, it begins to irritate the gums and damage the teeth.
