Halitosis is offensive breath to others, caused by a variety of reasons including but not limited to periodontal disease, bacterial coating of tongue, systemic disorders and different types of food. Gram-positive bacteria produce little or no malodor; most Gramnegative bacteria are potent producers of odoriferous compounds. Treatments corresponding to the causes of oral malodor include mechanical or chemical tongue cleaning, periodontal disease treatment, oral hygiene instruction and mouth rinses or mouthwashes.
