Some people grind their teeth unconsciously at night resulting in excessive tooth wear, joint and muscle pain. Some patients experience some limited mouth opening due to pain and muscle spasm. The first treatment option is to wear splint at night. The splint is a piece of clear acrylic which is custom made to suit each patient. It is design to absorb force from grinding protecting teeth from crack and wear. Moreover, the splint help distribute force level equally and balancing muscle tension while patients unconsciously grind.
