Dental question about taxonomy:symptom:bad-breath

Bad breath usually starts in the mouth, often from tongue coating or gum disease, but persistent odor needs an examination.

Bad breath, or halitosis, is an unpleasant odor in exhaled air. Bacteria can break down food debris and proteins on the tongue, around teeth, or in gum pockets, producing odor compounds; dry mouth, tobacco, dental decay, and some throat or stomach conditions can also contribute.

Brush twice daily with fluoride toothpaste, clean between the teeth, and gently brush or scrape the tongue. Drink water, avoid tobacco, and arrange an examination if the odor continues after improving these habits, because plaque, calculus, decay, or a gum pocket may need professional treatment.

Book dental care for persistent odor, bleeding gums, tooth pain, loose teeth, or a bad taste with swelling. Seek urgent care for facial swelling, fever, difficulty swallowing, or difficulty breathing, as these can indicate a spreading dental infection.

Ask whether the odor is coming from the tongue, gums, teeth, or another area, and whether you have decay or periodontal pockets. Ask which cleaning method is appropriate and whether dry mouth, medicines, tobacco, or reflux could be contributing.
