Hi! Chronic bad breath can have multiple causes poor oral hygiene, gum disease, tongue coating, dry mouth, tonsil stones, acid reflux, or even sinus issues. Since tonsil stones are being addressed by your ENT, I suggest visiting a periodontist or dentist again to rule out gum infections or tongue coating. Tongue scraping, hydration, and professional cleaning may help. No specific test always gives a clear cause, but a thorough oral and ENT evaluation usually identifies it. A joint approach by a dentist and ENT is often most effective for long-term relief.
Health Tips
Brush twice daily and clean your tongue gently with a tongue scraper.
Floss regularly to remove food particles stuck between teeth.
Use an alcohol-free mouthwash to avoid dryness.
Stay well hydrated — dry mouth worsens bad breath.
Avoid strong-smelling foods (onion, garlic) and tobacco.
Rinse your mouth after meals, especially if eating dairy or sugary foods.
If GERD or acid reflux is suspected, consult a gastroenterologist.
Chewing
sugar-free gum can help stimulate saliva and reduce odor.
Visit a dentist every 6 months for scaling and check-ups.
