What about the tongue?

This toothbrush was a replacement I picked up a couple of weeks ago.  It is the first toothbrush I’ve ever owned with a tongue cleaner on the back of the head.

There is a small section of raised rubber bumps and points which you can scrub your tongue with, giving it a nice massage while cleaning it off.

Nice addition to an age-old product. It is probably not the first time such a brush has been made, but it was new to me. I definitely enjoy the added value and cleaner mouth!

At this point, does this tool need to be called a “mouth cleaner” rather than just a “tooth brush”?
