Q. Hi Dr Safeer, i have recently had 4 lava crowns fitted to my front teeth . The 2 on my left side look wonderful ! the problem is the other two are not as good, on one the margin is visable (only a very small amount 1 mm ) and i am worried that the exposed original tooth is going to decay more quickly, and my other concern is my gum hasn’t filled the gap between the crowns leaving a deep recess and not only is it not athestetic it also gets food stuck in this gap ! do you think im within my rights to have the dentist rectify the work free of charge ? what can be done about the gum?? i am so worried! I had to work so hard to pay for the crowns. should i ask for a refund ? the dentist was a general dentist in haywards heath. thank you so much for helping me i am so pleased people like u help people like me god bless you
