Did you know what the perforated bumps on the back of a toothbrush are for? Cool design? To feel good against you gums? No! They put them there so people can brush your tongue! I had been brushing my tongue with the toothbrush part for years until I recent read the package on a new toothbrush. I have a feeling my toothbrushes are going last a lot longer now.
Bacteria can live on your tongue and give you sore throat and worse, bad breath!! There are no pictures that I could find on the web where it allows you to demonstrate the back of the toothbrushing on the tongue activity!!
