Why do our teeth chatter when it is cold?

Question

Why do our teeth chatter when it is cold? When my teeth chatter I can stop it by force, but eventually it starts again. Why does this happen?

Answer 1

Keeping the center of your body warm is very important for survival. so if the nerves even hint that your bodies center may get too cold, your muscles start twitching, causing your teeth to chatter and your body to shiver. Because your muscles are moving, it creates heat so that your body can be warmed up again.

Answer 2

It's an effect of shivering which, due to the activity of muscles, is the body's way of trying to warm itself up.

Answer 3

Your body knows it can create friction heat by shivering.  This is just transferred to the mouth.

Answer 4

It is a reaction caused by the nerves because when it gets cold, your body is trying get warm by producing movements like chattering teeth.

Answer 5

I think its the nerves in your body

P.S

i am probably wrong there  

good question

Answer 6

You wear heavy jackets.

Answer 7

maybe its because its some random body instinct lol

Answer 8

Because when you are cold your body naturally shivers, and teeth chattering is a symptom of shivering. You shiver because your body is trying to produce heat, and keep your temp consistant. This is the body's natural defense to hypothermia. When your teeth chatter, your teeth aren't the ones that are in control. Your periodontal and masseter muscles are being stimulated by your sympathetic nervous system to quiver, to create heat. This is the same reaction when your legs start to quiver, or your abdominal muscles begin to quiver. This is the body's natural mechanism to create heat (as the muscles quiver this creates friction inbetween the muscle cells, thus causing heat).
