Dear all. My right first premolar tooth was crowned 7 years ago on a screw . Suddenly started to move and the end it falls in my hand . So now either implant or crown lengthening surgery will allow dentist reach root of tooth deep inside 3 mm and then install two fiber posts and then crown . I did crown lengthening and I am really upset , the result was not as I like. I do not see it nice . I just did it yesterday so the gum line I don't like . Will the gum stay like this ? What I can do .
