Causes of halitosis can originate either inside or outside your mouth. A person with poor oral hygiene maintenance has a higher chance of halitosis than who regularly brushes. Common causes include gingivitis, periodontitis, dental caries, excessive plaque accumulation on teeth and tongue, pericoronitis, or oral ulcers. Food substances having a strong, pungent smell are another common cause. Frequent smoking, alcohol, or caffeine intake results in temporary bad breath. Any diseases or medications that cause dryness of the oral cavity are another contributing factor. Outside the oral cavity, inflammation of the tonsils or sinuses is another important factor that affects the quality of breath. Gastric diseases, especially gastroesophageal reflux, are another cause of halitosis.
Bad breath, also called halitosis, can be embarrassing, especially when other people comment on it, making you feel self-conscious about talking or even smiling. But chronic bad breath can also be a sign of a larger problem. Most cases of bad breath occur after a meal with onions or other ingredients with strong odors, or after going a long time without brushing. These cases are resolved by brushing or gargling with mouthwash. Chronic halitosis, on the other hand, occurs frequently and can only be temporarily relieved with basic hygiene. This is because chronic bad breath doesn’t exist on its own; it’s often a symptom of a more serious problem and cannot be resolved without the proper treatment. Poor oral hygiene habits: infrequent brushing, not flossing and not rinsing with mouthwash can lead to excessive, odor-causing bacteria in the mouth Chronic illnesses: poorly controlled diabetes can cause a buildup of sugar, which attracts bacteria, while kidney failure can cause a fishy smell in the mouth Medications: Antidepressants, diuretics and other medications that cause dry mouth can reduce your saliva production, making it more hospitable to bacteria Gum disease or infection: whether at the gum line or in the tooth itself, periodontitis and other infections in the mouth can leave an unpleasant taste and a bad odor in your mouth What are the remedies for bad breath?
