Question

1. Sometimes, while eating we bite our own finger or
tongue by mistake?​

Answer 1

Answer:

Barring dental issues, we bite our cheeks and tongue when eating because of friction. When we bite ourselves accidentally, it’s a sign that parts of our mouth are dry.

When your mouth is chewing, your teeth are constantly running against the cheeks because your cheeks are what keeps your food in, and sometimes comes into contact with your tongue because your tongue keeps your food moving. In fact, evolution has developed rather clever methods to keep yourself from damaging these parts: in the slippery gummy surface of your mouth, and in the way you produce saliva inside your mouth. This produces natural lubrication for you to chew on.
