What is the cause of bad breath??
There are many causes.
Teeth that are decayed.
One of the first things to do in order to determine the cause of your
bad breath is to get to a dentist and get a good cleaning.
This will make sure you start off with a clean slate.
For 2 weeks commit to brushing after each meal.
For 2 weeks commit to flossing daily.
And for 2 weeks commit to rinsing with a mouthwash such as Listerine, daily.
(Important note: You also need to brush your tongue.
Tongue scrapers, pictured below, are also available.)
After the 2 week period see how your breath is.
If it still smells as fresh and clean as it did when you left the dentist office
then your bad breath was, more then likely, a result of poor oral care.
This would be good news because all you need to do is continue
your new pattern of brushing, flossing, and rinsing and your bad breath should be history.
If things return to there normal, bad breath, state then other things need to be considered.
