If you have Parkinsons Disease, DO NOT get a dental xray. The danger of killing more dopamine producing neurons is far too great.
Giving dental xrays to Parkinson patients is not good dentistry. Rather, it is nothing short of reckless dentistry. Many dentists will argue that xrays are required for a specific Level of Care. This so called Level of Care is set by the states Board of Dentistry, who have a decided mission to support the income of member dentists.
I have experienced dentists and dental hygienists literally engage in intimidation of patients to be able to take xrays. Even when the patient has no dental problems. If dentists are concerned about liability (which they claim) they should consider the liability they would face if they worsened the condition of a Parkinsons patient.
Several studies have positively linked dental xrays as a causal factor for meningioma brain tumors. The authors of these studies recommend that dental xrays not be given more often than once every three years; and this is for healthy non Parkinson patients.
Additionally, if dental xrays are so benign as dentists argue, then why do dental hygienists go into the next room when taking xrays? Probably because the effect of xrays is accumulative. If you have received dental xrays every year there is a possibility that this has exasperated your Parkinsons condition. There is also an argument that the dental xrays may be responsible for your Parkinsons Disease.
So far there have not been any studies positively linking dental xrays to Parkinsons Disease. However, radiation kills cells. It is a very short step in logic to link dental xrays with Parkinsons; and literally irresponsible to claim that there is no relationship.
