Dear Mr. Owen,
Thanks for participating in the Forum and for your question.
It's best not to attempt to interfere directly with a habit pattern such as nail biting. More often than not, attempts to stop the behavior are met with frustration and only exacerbate the problem.
However, there are a couple of things to watch. Habits such as nail biting are generally a form of

Drug-induced hypertension
Essential hypertension
High blood pressure (hypertension)

Hypotension
Ileus - x-ray of bowel distension
Mixed tension migraine
Multiple system atrophy

Pseudotumor cerebri release/reduction. Now, this does not mean that you'll be able to identify a 'source' of

Pseudotumor cerebri will help reduce and maybe even eliminate the nail biting.
If the habit is confined to particular times or situations (e.g., while watching television, riding in a car, etc.), you can offer some alternative, such as fingering some 'worry beads' or squeezing a

Tennis elbow ball or some other such object. In my clinical practice I have also had some success, when nail biting occurs repeatedly in a particular context, with having the child wear cotton mittens or gloves. After a while, the habit pattern wanes and ultimately disappears. But try to avoid the situation of engaging in a struggle around the behavior. If you can engage your daughter in a playful fashion to attempt some change, it's worth a try.
