Mouth guard having internal components for sensing impact forces

A mouth guard system for detection impact forces of a user while the user is participating in a first activity or a second activity, comprising:

• a mouth guard comprised of flexible material, the mouth guard having a front portion with a generally arched-shaped peripheral side for facing the buccal region and a depressed portion adjacent to the front portion that is shaped to receive teeth of the user;
• a linear force sensor and a rotational force sensor for detecting forces experienced by the user during impacts, the linear force sensor and the rotational force sensor being embedded within the flexible material of the mouth guard;
• a memory device embedded within the flexible material of the mouth guard, the memory device storing first impact threshold data associated with the first activity and second impact threshold data associated with the second activity, the first impact threshold data being different from the second impact threshold data, the first impact threshold data being used while the user participates in the first activity, the second impact threshold data being used while the user participates in the second activity, the first activity being a different type of physical or sport activity than the second activity;
• a first notification feature for indicating to another person that the user has experienced an impact that exceeds a first impact threshold defined by the first impact threshold data;
• and
• a second notification feature for indicating to the user that the user has experienced an impact that exceeds a second impact threshold defined by the second impact threshold data, wherein the second notification feature is different than the first notification feature.
