AJ, a patient from Mississippi, asks for help:
I had a dental implant put in 4 years ago. I have returned to my dentist 3 times because the crown became loose. Now after seeing a different dentist who reviewed my x-rays for the past 4 years, he says that the abutment was never properly seated onto the implant and that is why the crown keeps coming loose. After cutting off the crown and removing the abutment the screw is stuck fast in the dental implant and he cannot get it out. What do you recommend to correct this?
