A Toothbrush may do a fine job of cleaning the front and back portions of your Teeth but that's only half the work done. There are spaces at the side of your Teeth which have to be cleaned as well. These are the interdental spaces that remain open to the entry of tiny bits of food particles. A breeding ground for bacteria, so to say. The foundation of gum disease to be more precise.

The bacteria that feasts on your food also nourishes, grows & builds a 'biofilm' at your expense. If left unchecked, this film converts to plaque and that's when your problems begin. Interdental brushing can poke and disrupt the film and if practiced daily, the bacteria doesn't stand a chance to regenerate. No biofilm, no plaque! Simple.
