Only @ night time. My back teeth, mostly bottom. Also jaw & ears hurt very bad. Can't lay down. Causes tremendous pain. Orajel causes white spots?

Cause. Before applying treatment the cause of your pain has to be determined. It may be bruxism, infection, parafunctional habits, joint dyscrasia, etc. Please see your Dentist. Referral to an Oro-facial Pain Expert may be in order. Oracle is for superficial gum lesions, so probably not the treatment of choice for your problem.
Why suffer ? You've got tremendous pain. Orajel is not going to treat your condition. Please see a local dentist and physician for a sorely needed exam.
