gums
Gum is a substance, usually tasting of mint, which you chew for a long time but do not swallow.
I do not chew gum in public.

Your gums are the areas of firm, pink flesh inside your mouth, which your teeth grow out of.
The toothbrush gently removes plaque without damaging the gums or causing bleeding.
