In wrestling or any other fun thing you choose to do you need to pay attention to your teeth. In sport I think it is not allowed to bite during the activity but if you are learning to use all that you have and to survive it is of importance to know that you can use your teeth and voice to more than food and voicing your opinion. For example there are a lot of holds people enjoy using where your teeth are forcefully brought to your partners neck and a simple bite will set you and his mind free. A hold where you are smothered to his side will release if you tickle his ribs with your teeth and a loud shout can unnerve many if issued without bodily tension while you are held. Think about what you can do to survive and protect your loved ones. USE your head, all of it.
