If nocturnal teeth grinding to the point of fracture were an Olympic sport, I would be a champion  This morning I had the gold crown pictured here added to my collection.  When compressed air was used to dry the underlying tooth before applying adhesive, I experienced a level of pain not known to me in all my life.  The dentist was surprised by my reaction but said it was not uncommon to have a hypersensitivity to hot or cold temperatures. If the 3-second blast of air had gone on for another second, I swear I would have lost consciousness.

Note to Children:  Consistent use of a night guard will prevent subsequent misery if you suffer from bruxism (the official term).
