Review title is A family pack of nice metal tongue cleaners [SEP] This is a box of 4 metal tongue cleaners. The metal ones like this work much better than the plastic ones - you get a nice clean sweep in just a move or two as long as you don't press too hard. They rinse off easily, don't rust, and using a tongue cleaner can keep your breath fresher, improve your dental health and just make you feel better. I've known at least one dentist who believed that tongue cleaning can help your teeth recalcify as you age but that's just anecdotal information. I've used them for years and I really recommend them.
