The tooth does not hurt but it does bother me that the sensation is constant.The sensation is similar to having a cavity and eating sweets but it is waaay milder.I had x-rays taken and they do not show anything.Neither does the actual tooth under the crown.(I have a temp).The crown was loose at some point over the years but I had a dentist put it back in.Any idea what this might be?Should I ask the dentist to remove post so I can have an endo take a look with a microscope?Will it solve the prob?
