Travel (Motion) sickness is a condition in which a disagreement exists between visually perceived movement and the vestibular system's sense of movement. It is based on currently widely accepted "sensory conflict or neural mismatch theory". Teeth are in close proximity to the brain's bone structure and its soft tissue. Any force, chemical, electrical, or imbalance in the pressure on the teeth or absence of support for the teeth or any other type of disturbance in our teeth is directly transmitted to the brain and can result in motion (travel) sickness. When dissimilar metals are placed in our mouth, an electrical circuit between the teeth can be setup and disrupt the brain's electrical functions. It is recommended that each individual should seek advice with regard to travel plans from the dental practitioner most familiar with their case. About 33% of people are susceptible to motion sickness in mild circumstances, nearly 66% of people are susceptible in more severe conditions. Effective drugs for combating motion sickness include antihistaminics, antimuscarinics, serotoninergic receptor agonists etc, however complete information concerning physiological basis of motion sickness is still poorly known and requires further research.
