Bad breath is also known as halitosis or oral malodor. It is a prevalent and treatable condition for many individuals. Odor generally can come from the teeth, mouth, or due to a particular health challenge. People with bad breath can have it due to a chronic condition or temporal challenge.
According to the American Dental Association, a minimum of 50 percent of adults have faced halitosis problems once in their lifetime. A bad taste in the mouth may be noticed in addition to a bad breath. If the taste is due to a health condition, it may not be treatable by brushing or mouthwash. This article will expressly show in full detail the top ten causes of bad breath. 
Poor Oral Hygiene
Maintaining good oral health is essential for reducing bad breath. Good oral hygiene involves the regular cleaning of the teeth and the entire mouth. The mouth needs to be appropriately cleaned because they may contain food particles, and sticky buildups of bacteria can be formed in the teeth. Generally, the mix of bacteria and decaying food in the mouth releases an awful odor, so brushing is essential.
It’s important to replace toothbrushes every few months since many microorganisms can stay in the toothbrush and infect the mouth. The presence of sticky build ups (plaques) in the mouth causes foul odors. Besides, plaque buildups could lead to periodontal and cavities disease. Bad breath may be a problem for those who wear dentures and don’t clean them regularly.
