I had fillings put in 2 teeth on left side of upper and lower molars. Both of these teeth had composite fillings put in over 2 months ago. As soon as the fillings were placed in the teeth I could feel the pressure feeling. It feels like you are pushing against the tooth or like the tooth is being squeezed. I have since then had the upper molar root canal ed and still have the pressure sensation. Has anyone ever had this happened before during dental treatment. Is there a possible explanation for this? I have had dental work for 45 years with fillings and crowns etc.. I have never went through this before. I am hoping someone else can tell me whether they have had this or if there is an explanation for it ???? Thank you.
