The sulfur compounds are created by the bacteria when they digest protein. These bacteria live in biofilm that coats our teeth, gums, tongue, throat and nasal passages every day. so, to avoid bad breath, follow these tips:

• Before choosing a mouth wash, get the recommendation of your dentist. Use an antiseptic and plaque reducing mouth wash.
• Brush you teeth at least for 3 minutes continuously. It is important to floss after you brush. Food particles trapped between the teeth can be cleaned only by flossing.
• Brush your tongue or use a tongue scraper to clean your tongue.
