A vertigo is a disabling sensation in which the affected individuals feels that either he himself or his surroundings are in a sate of constant movement. This is symptom of disease in labyrinth of inner ear or vestibular nerve. The vestibular nerve carries information of posture, movement and balance. The changes in the jaw position can disturb this nerve as it lies near to jaw in ear So this problem of vertigo can arise.
Since having upper and lower braces on my teeth I have suffered from very disabling bouts of vertigo. I was diagnosed as having Meniers disease ( a horrible degenerative disease) of which I had only one symptom; vertigo. Since then and several stressful, and expensive visits to various doctors and alternative therapies I have discovered the cure; osteopathy. The osteopath confirmed what I had thought that the re alignment of my jaw caused devastating episodes of vertigo. I have since been treated and cured. Good luck.
You should consider a simple bonding restoration if your only problem is
a small gap between the front teeth...less time, trauma, stress.
