Halitosis

Halitosis is the clinical term for chronic bad breath, and it deserves a clinical answer rather than a fresh-mint cover-up. The posts here cover what causes halitosis at a bacterial level, how it's diagnosed in practice, and the treatments that actually resolve it long-term. Each article is grounded in the work we do at the Center for Breath Treatment in Berkeley — including the diagnostic tools, oral-care protocols, and follow-up routines we use with patients who have tried everything else.
