What's Actually Happening
What Causes Persistent Bad Breath
The clinical term is halitosis, and it affects a significant portion of adults — most of whom have tried to solve it with mints, mouthwash, or more frequent brushing, with limited success. That's because most of those approaches address the symptom, not what's driving it.
The most common dental cause is gum disease (periodontal disease). Bacteria accumulate below the gum line in pockets the toothbrush can't reach. Those bacteria produce volatile sulphur compounds — the characteristic smell of halitosis. Dr. Maddipati examines the gum tissue specifically to assess whether bacterial accumulation below the gum line is a contributing factor.
📊 By the numbers: Gum disease is the most common dental cause of chronic bad breath — and nearly 42% of U.S. adults over 30 have some form of it. The good news: for most patients, treatment is straightforward once the cause is identified.

Other dental causes include: cavities (bacteria-filled decay has an odour), poorly fitted restorations with areas where bacteria accumulate, dry mouth (saliva has antibacterial properties — less saliva means more bacterial activity), and coated tongue. In some cases the cause is non-dental — sinus issues, acid reflux, or systemic conditions — and Dr. Maddipati will tell you honestly if she thinks the cause is outside dentistry's scope.
There is no judgment in this appointment. Chronic bad breath is a medical issue, not a hygiene failure — and it's one of the most common things patients are reluctant to bring up. Dr. Maddipati approaches it the same way she approaches every appointment: directly, clearly, and without making you feel embarrassed for having come.
