My young nephew's halitosis let up after his mom started using a tongue scraper on him nightly. We started using them in our family as well. Our favorite one is the Tongue Sweeper since it's metal and lasts a long time without nicking and is easily sterilized.

I used to use one of those too but found a much easier way - I just scrub my tongue with my toothbrush after my teeth are done. One tool, one step, one place of storage. Win-win.
Cleaning your tongue regularly can help with overall oral hygiene and bad breath. A spoon can be an effective tool for cleaning your tongue. This is a page about spoon for tongue cleaning.
