I have reflux daily which comes up into my throat & mouth for 5 years. my throat hurts all day. i have a dental appointment coming up and the dentist is insisting on x-rays of my mouth. i am fearful of x-rays on my raw throat. should i be fearful?

I wouldn't consider dental X-rays a problem in this setting. It is important to detecting early signs of treatable damage to your teeth. Reflux to that degree does create greater risk for your oral health and should be properly monitored.

No you should not be fearful of the dental x-ray, not for a moment, but you should be concerned about not treating the reflux. Gastroesophageal reflux disease (GERD) is a chronic digestive disorder that affects the lower esophageal sphincter (LES), which is the muscle that connects the esophagus to the stomach. Left untreated, GERD can increase the risk of developing cancer.
