The causes of bad breath

In most cases, bad breath resulting from the accumulation of food debris.They can comfortably between teeth and participate in the formation of plaque, which lines the teeth and tongue. The smell comes from the degradation of food debris by oral bacteria, an action which produces volatile sulfur compounds.
A brushing teeth at least twice a day and a scraping language should help eliminate odors.
A defective oral hygiene is conducive to the development of gingivitis (inflammation of the gums) and periodontitis (disease tissue supporting teeth). These conditions can cause bad odors, like the gradual decline of the gums when plaque progresses or when a tooth becomes mobile. In fact, any surface and especially any gap between teeth and gums tend to retain the dental debris and promote the action of bacteria and thus bad breath.
