Some people brush, floss and scrape their tongue perfectly and still have foul breath — and the reason is often tonsil stones, calcified pellets of bacteria hidden in the crypts of the tonsils. Here is what they are, how to check for them safely, what you must NOT do, and when to see a doctor.

Tongue scraping works — it measurably reduces the volatile sulphur compounds that ARE the smell of bad breath. But almost everybody cleans the tip and front of the tongue, which is nearly clean already, and never reaches the back, where the odour-producing bacteria actually live. Here is the evidence and the correct technique.

Bad breath is caused by volatile sulphur compounds released by anaerobic bacteria on the back of your tongue and between your teeth — so a minty toothpaste masks the problem while a zinc or antibacterial formula actually targets it. Here is every bad breath toothpaste mechanism rated honestly, plus the three things no toothpaste can fix.

Bad breath is not caused by poor hygiene alone. People who brush twice a day can still have it — because the real source is bacterial, and it lives where a brush cannot reach.
