Chronic bad breath (halitosis) is primarily caused by odor-producing bacteria that accumulate on the back of the tongue, beneath the gumline, or inside untreated cavities and old dental restorations.
Occasional morning breath is normal and relates to reduced saliva flow during sleep. However, persistent bad breath (chronic halitosis) that does not resolve after brushing is typically caused by anaerobic bacteria living in low-oxygen oral environments. These bacteria metabolize food proteins and shed cellular debris, releasing volatile sulfur compounds (VSCs). Professional evaluation identifies whether the source is tongue biofilm, periodontal pocketing, dental decay, or medical factors.
