Nail biting leads to teeth grinding

Anxiety disorders affect approximately one in six adult Americans, according to the National Institute of Mental Health.
A new study by Tel Aviv University researchers, published recently in the Journal of Oral Rehabilitation, finds that anxiety experienced in social circumstances elevates the risk of bruxism — teeth grinding which causes tooth wear and fractures as well as jaw pain.
“This is not a dental problem, but one with clear dental consequences,”
• Nail biting can wear down your teeth over time, causing enamel wear and uneven biting surfaces.
• Nail biting is bad for your jaw. It can contribute to Temporomandibular (TM) disorder, which causes jaw pain, headaches, and locking and popping of the jaw.
• Beyond the effects on your teeth and jaw, there are also sanitary concerns, when you bite your nails, you are exposing yourself to illness causing germs that transfer from your hands to your mouth.
