Odd... I haven't seen this before.

This or any odd type of deformity is usually from an animation in an attachment. The solution is in finding the attachment or animation. To do that change to the Test Female avatar. (Top menu ->Developer->Avatar->Character Tests --- you may have to press Ctrl-Alt-Q to reveal Developer)

Once you are wearing the test avatar try whatever it is that distorts your mouth now. It should not distort. If it does, whatever you just tried is the problem. If no distortion, add your normal outfit back one item at a time trying whatever causes the distortion with each addition. You'll find the problem.

This is most likely caused by a voice activated gesture that you have active that is playing chatting animations that are not compatible with your mesh head.
Search your inventory for the term active and disable all your active gestures till you find the culprit.
