There are many causes of bad breath. See your dentist on a regular basis, maintain proper medical and dental history and provide this information to find out the root cause. Bad breath can also be caused by alcohol and tobacco use, poor oral hygiene, oral disease, dry mouth and other factors. Other causes include diabetes, sinus and throat infections, lung infection or lung abscess, liver / kidney failure, gastrointestinal disease and extreme dieting.
Note: Consult a dentist or dental hygienist when choosing an oral hygiene tool to help remove plaque and odor-causing bacteria, and review your oral routine at home. You should also seek advice from dental experts on which oral hygiene products (antibacterial toothpaste, antibacterial mouthwash, tongue brush or tongue scraper, and cleaning appliances to clean between the teeth) to use to help eliminate bad breath.
To ensure fresh and clean breath, regularly implement good oral hygiene habits at home and follow advice dental professionals have discussed with you.
