I am missing 2 bottom molars and 1 bottom wisdom too. I still have 3 wisdom teeth and my bottom front teeth are crooked due to teeth shifting wich causes an uncomfortable bite. After I eat my jaw gets very tired. a couple months ago I started having face muscle tis all over my face. Under my eyes, cheek muscles, under my left nostril and near my jaws constantyly NON STOP!! VERY ANNOYING!!! could there be a relation between face muscles twitching and missing, crooked teeth?
