Hi Felicia,
The sensitivity, weird pain and temporary mobility of your lower front teeth upon wakening generally indicates a clenching/grinding of your teeth habit. As you clench down or grind your teeth your tongue pushes forward. If you do that enough times during the night, the pressure of the tongue against the teeth will make them feel mobile. The sensitivity is because the periodontal ligaments, which are like live elastic bands that surround the circumference of the root of each tooth in the jaw bone, become inflamed from the pressure against the teeth. If this habit continues, the nerves inside of the teeth will also become inflamed and eventually become sick and die. So this is something that needs to be addressed and cured.
Here is a great you tube video with experts talking about TMJ issues and treatment.
