Q. Hi I had part of the side of a molar that is next to a removed tooth years ago fell away, mild aching,sensitive really, saw my dentist who removed the rest of the filling then placed a tempery filling in it to see if it settled down, I had no problems but unfortunatly this came out 10 days later due to me biting something hard,I returned to him and he said he was happy to put in a perminent filling,due to me not experiencing any problems.Since then i have had continueing sensitivity on eating,drinking hot and cold and now on taking in air ,inside and outside the house.I am not sure about going back to him as he is new to me as my old dentist that I trusted implicently retired and he took on the practice.Heseems nice enough just wasnt convinced on my last visit ,that he did the treament correctly, didnt apear to put much filler in my tooth despite proding it an awfull lot.I know he will want to do root canal,as this is what he spoke of last time,I am at a loss to know whether this would be the way to go ,as I experienced no problems when the tempery filling was in,can you advise me please,on my best course of action or treatment.Do I go somewhere else for treatment,or return to him,for root canal.I am on a monthly private scheme.
