I have suffered and been treated for migraines for over 25 years. After mentioning this to Dr. T, he thought a bite guard would alleviate the headache I woke up with every morning. I took his suggestion and it was the best thing I could have done for myself. The results were immediate. I no longer wake up with a morning headache. Thank you again Dr. T. and to anyone else who may suffer, get a guard, it works!!
