Every one of us only have one set of teeth, but with the marvels of modern dentistry, anything that is broken can quickly and painlessly be mended. A skilful dentist can even make that smile look even better than it initially did. There are many causes of a chipped tooth: Teeth Grinding (Bruxism): Inadvertent, chronic teeth grinding and clenching usually occurring at night time during sleep. Teeth grinders are frequently unconscious that they have developed this pattern. Symptoms often include chipped or fractured teeth, jaw pain, overly tender teeth, stressed facial and jaw muscles, headaches, damage to the inner cheek tissue, extensive wear and tear to the dental tooth enamel, exposing the inner portion of the tooth, and clicking of the temporomandibular joint.
