I had fillings done around two months ago. Two of my teeth with fillings started to hurt three days ago. Also, I had pain in my ears. However, I also had pressure and crackling going on in my both ears. I have had issues going on with my ears for a while, I have been on a decongestant from an ENT doctor and might need to have tubes placed. I also have TMJ problem. I am not sure if my ears are causing the pain in my teeth or vice versa. But, after increasing the dosage of the mucus D medication, it subsided the pain. The teeth pain was much better today. I have more fullness in my ears, and my jaw hurts. I feel pressure on both sides of my teeth. I used to have a mouthguard made by my dentist. After my wisdom teeth removal, other teeth got shifted, and the mouthguard does not fit any longer.
