I have a crown with post in front, which revently got chipped It is very unconfortable and is sharp , which needs me to be extra catious as my tongue has been slit multiple times by the sharp corner. My question is can this be fixed without replacing the crown? As my crown has a post and as i was told by one of the dentist that it is impossible to replace the crown. I just want my crown to look normal and fet rid of sharp edge.
