What to do if i have bad breath how it can be cured?

Many causes...: Bad breath or halitosis, can have several causes, ; it is sometimes multi-factorial. Accumulation of plaque and tartar in between ;; behind the teeth + presence of cavities are common causes. Also, many people have more accumulation of germs and debris on top surface of their tongue (to be brushed daily too). Others:presence of "post nasal drainage", acid reflux/ digestive problems ; some foods.

Bad Breath: Bad breath can be caused by medical or dental issues or combinations of both. See the following website as a starting point to understand the causes. By far, poor oral hygiene is the most likely cause. Then see a local dentist to eliminate dental causes. He\she may refer you to a physician if necessary.

See your dentist: Just trying to use mouth washes and breath mints may temporarily help, but i would see your dentist to get a definitive way of helping you. You may require additional dental cleanings or need to be educated in proper hygiene.
