Brief Summary:
This purpose of this study is to evaluate the safety and efficacy of treatment with nasal CO2 in the treatment of pain and other symptoms related to temporomandibular disorder (TMD).

Condition or disease Intervention/treatment Phase
Temporomandibular Disorders Pain Headaches Drug: Nasal Carbon Dioxide Other: Air Phase 2

Detailed Description:
This is a randomized, controlled trial evaluating the safety and efficacy of nasal carbon dioxide for the treatment of pain and other symptoms related to temporomandibular disorders (TMD). Approximately 115 men and women ages 18 to 70 years old who have a history consistent with TMD-related pain for at least 3 months and meet all other eligibility criteria will be enrolled in this study. There may be up to two (2) visits to the clinic, screening and treatment. Screening and treatment may occur on the same day.
