(2) This chapter does not apply to the use or authorization of use of an individual's or personality's name, voice, signature, photograph, or likeness, in any of the following:
1 Dry mouth can be a result of nerve damage to the head and neck area from an injury or surgery. 2  Dehydration. 3  Conditions that lead to dehydration, such as fever, excessive sweating, vomiting, diarrhea, blood loss, and burns can cause dry mouth. 4  Surgical removal of the salivary glands. 5  Lifestyle.
Having inadequate saliva can over time cause damage to the teeth. One of the roles of saliva is to protect against cavities. In severe cases, dry mouth can make it difficult to swallow and talk, so it is important to keep the mouth moist. Breathing strictly through the mouth can make the mouth drier, but learning to inhale and exhale through the nose may help, claims the Mayo Clinic.
