Why do i like to pick my gums and how do i stop?

Picking your gums : Because you are packing food between your teeth or just as a habit ? In either event, using soft-picks by gum (sunstar) can actually be beneficial in the revival of trapped good and stimulation of the gums to toughen them up. But like everything in life - moderation is the key. Hope this helps.

Habit: It is a habit no different than cracking you knuckles. Assuming you have healthy teeth and gums there is little to worry about.
