Dan: I have been diagnosed with Chronic Cluster Headaches. I also grind and clench my teeth at night. My pain is on the right side always.
Dr Shapira Response,
Good News, Physiologic Dentistry may help control or eliminate your cluster headaches. It is important to remember that the human body and brain is very complex and while Physiologic Dentistry is a key component it is a part of a larger, whole body approach to chronic pain.
Dan, Sorry to hear about your cluster headaches. While the causes of Cluster Headaches are not well understood they are unquestionably related to the Trigeminal Nerve, the same nerve responsible for TMJ disorders and headache, sinus pain, facial pain and related symptoms. That is why a Physiologic Orthotic is probably a vital aspect of your treatment.
We know that 100% oxygen can relieve classic cluster headaches. We also know that almost all nocturnal clenching and grinding of the teeth is related to sleep disordered breathing that causes oxygen desaturation and disturbs hormonal systems. The connection is critical.
I cannot over-emphasize the importance of being evaluated for sleep disordered breathing as a possible cause of multiple pathologies predisposing you to cluster headache.
Much of the literature on cluster headaches point to a hormonal link. When sleep is disturbed most of the bodies hormonal systems go into malfunction, especially Growth hormone, melatonin, thyroid, sex hormones, insulin resistance and cortisol. The effect of sleep disordered breathing on heart rate variability is enormous.
TMJ disorders and sleep disorders both upset the functions of our circadian clocks that are also implicated in cluster headaches. The circadian connection is why cluster headaches have received their name. They come in periodic clusters that are related to multiple enviromental influences of the season, weather etc.
A thorough diagnosis by a trained Physiologic Dentist(ideally a Fellow or Master of ICCMO due to advanced training and commitment to the science) would be an excellent first step. The use of a Neurmucular Diagnostic Orthotic may by itself eliminate or greatly improve your symptoms. I would strongly suggest you take a broader approach and also seek out a Board certified Diplomat in Dental Sleep Medicine trained in treating sleep disordered breathing and sleep apnea. Correcting sleep disordered breathing whether it is snoring or sleep apnea or anything between can have dramatic effects on your cluster headaches.
This will address the trigeminal nervous system which contributes over 50% of input to the brain after the reticular activating system. The sleep treatment will eliminate or minimize circadian disruptions. It will also allow hormonal systems to be properly regulated and will eliminate the oxidative stress of repeated hypoxias (drops in oxygen).
A doctor trained in Sphenopalatine Ganglion blocks (which addresses the autonomic nervous system of multiple cranial nerves including the Trigeminal Nerve and trained in treating Myofascial Pain and Dysfunction and Fibromyalgia via trigger point injections can offer additional methods of eliminating your cluster headaches. Diplomats of the American Academy of Pain Management understand the complex nature of chronic pain. Be wary of doctors who only “throw medications” at the problem because they often only treat the symptoms and not the underlying causes of the disorder.

This new abstract from PUBMED.gov explains how Trigeminal Nerves can be affected by reactive oxygen, exactly as created by sleep disordered breathing.

Reactive oxygen species induce procalcitonin expression in trigeminal ganglia glia.
Raddant AC1, Russo AF.
To examine calcitonin gene-related peptide (CGRP) gene expression under inflammatory conditions using trigeminal ganglia organ cultures as an experimental system. These cultures have increased proinflammatory signaling that may mimic neurogenic inflammation in the migraine state.
The trigeminal nerve sends peripheral pain signals to the central nervous system during migraine. Understanding the dynamic processes that occur within the trigeminal nerve and ganglion may provide insights into events that contribute to migraine pain. A neuropeptide of particular interest is CGRP, which can be elevated and play a causal role in migraine. However, most studies have overlooked a second splice product of the Calca gene that encodes calcitonin (CT), a peptide hormone involved in calcium homeostasis. Importantly, a precursor form of CT called procalcitonin (proCT) can act as a partial agonist at the CGRP receptor and elevated proCT has recently been reported during migraine.
We used a trigeminal ganglion whole organ explant model, which has previously been demonstrated to induce pro-inflammatory agents in vitro. Quantitative polymerase chain reaction and immunohistochemistry were used to evaluate changes in messenger ribonucleic acid (mRNA) and protein levels of CGRP and proCT.
Whole mouse trigeminal ganglia cultured for 24 hours showed a 10-fold increase in CT mRNA, with no change in CGRP mRNA. A similar effect was observed in ganglia from adult rats. ProCT immunoreactivity was localized in glial cells. Cutting the tissue blunted the increase in CT, suggesting that induction required the close environment of the intact ganglia. Consistent with this prediction, there were increased reactive oxygen species in the ganglia, and the elevated CT mRNA was reduced by antioxidant treatment. Surprisingly, reactive oxygen species were increased in neurons, not glia.
These results demonstrate that reactive oxygen species can activate proCT expression from the CGRP gene in trigeminal glia by a paracrine regulatory mechanism. We propose that this glial recruitment pathway may occur following cortical spreading depression and neurogenic inflammation to increase CGRP nociceptive actions in migraine.
