Here are simple methods to help test yourself for bad breath.
- First, take a piece of unwaxed, unflavored white dental floss. Floss between your upper and lower back molars. Now examine the floss. Is it red or brown? Wait about 45 seconds and then smell it. Does it have a bad odor? If so, then you probably have bad breath.
- Next, with clean fingers pull your tongue forward. With your other hand and a clean white washcloth, rub or scrape the furthest back portion of your tongue two or three times. Wait for 45 seconds and then smell the cloth. Is there a bad odor?
