Category “Dental Crowns”

Hi I have just had a crown fitted on a previously (23yrs ago) root filled molar (1st molar from front) that I am not happy with. Firstly it has a grey line around the gum line that looks horrible (reminds me of dirty finger nails!) and secondly the colour is at least a shade lighter than my own teeth which makes it very noticeable when I smile – bringing attention to the ugly grey gum line. My dentist has told me that the crown is ceramic on metal; the back cusp of the crown is all silver which I am not overkeen on but am given to understand that its more practical. My question is – is the grey line to be expected because of the previous root canal treatment or should I be able to expect a natural looking tooth right to the gum line rather than an obvious fake. Or is it me expecting too much. My teeth otherwise are in quite good condition. I would be grateful for your advice before I go back this Friday as I feel that my dentist will try to ‘fob’ me off with nonsense, as when she prepared the tooth for the crown she did not put on a temporary tooth but left me with the prepared ‘stump’ incl post. When I asked her if she would put a temporary tooth on she said that as she had now taken impressions a temporary tooth could ‘alter’ the prepared tooth when she came remove the temporary – altering the fit of the new crown! I have now learned that this is a load of rubbish and any temporary would be fixed with temporary paste which would be almost ready to fall off as I returned for the permanent crown 1-2 weeks later. I now think the that fact that she was running half hour late might have more to do with it. This is my first experience of a crown and my first experience with this particular dentist. i look forward to your reply many thanks
