Grinding and clenching of teeth is medically called bruxism. Stress was thought to be the reason behind it but latest researches have confirmed its relation with sleep apnea. Brain cycles through lighter and deeper stages of sleep during night. All the muscles in the body fully relax during the deep cycle. This troubles the airway and causes heaviness in jaw and blockage of the airway by the tongue. Scans taken at this stage show that the grinding of teeth reopens the airway and the person is able to breathe again. It is the physiological response caused by the hypercapnia (increased CO2 in the body). Thus, grinding is one of the symptoms of OSA that can save a person’s life. But conversely, causes morning headaches and TMD in the long run.
I used to have constant headaches for nearly 20 years. I've met lots of ENT surgeons and neurologists and have been consuming their medicines until I heard about Dr. Raj's NMD therapy from a friend of mine who got cured by him. I am really thankful to him for freeing me from my aches. I never realized my tiredness during any physical activity could in any way be related to my snoring.
