Review title is Great For Scraping Gunk Off the Tongue [SEP] These tongue scrapers do an excellent job of getting all the yucky stuff off your tongue which is LOADED with bacteria and is the main source of halitosis.  I always brush my tongue with a stiff bristled tooth brush, then my teeth with my Sonicare and to finish off the routine I use my tongue scraper to get the last bit of slime off my tongue.  I've used a plastic tongue scraper for years and it does real well and so do these metal ones.
