are we supposed to brush our tongue?

some toothbrushes have a rubber brush on the back side of them thats for your tongue

you can do it if you wanna, i do it sometimes but if you go too far back you might gag

yes I brush my tongue when i brush my teeth. and sometimes the pick tooth floss I use has a tongue scraper that I use as well. Bacteria gets on your tongue too like your teeth so need to keep that clean as well

yes, i do it after brushing my teeth

I do brush my tongue because I have one of those tongue scraper thingies on the back of my toothbrush but I don't go far back.

I only do the far back.

For practice.

Obsolete :

Yea I totally brush my tongue with my tooth brush. esp after I eat garlic or onion, that stuff doesn't leave you

I do.
