Why does cleaning my tongue make me gag?

For many people, placing a toothbrush or tongue cleaner near the back of the tongue can trigger the gag reflex. In order to stop this, it may help to begin by placing the scraper or brush in the middle of the tongue the first few times you clean it. Then, as you become more comfortable with the practice, you can gradually put it farther and farther back in the mouth until you can clean your entire tongue.

By adding tongue cleaning to your oral hygiene routine, you can not only improve your breath, but your oral health in general too.
