Earlier this year, I completed the six month or so long process of getting a dental implant on #18. Ever since the crown was placed on the implant, the implant hasn't felt right, despite my dentist making several adjustments and my oral surgeon's assurances that nothing seems wrong with the implant (x-rays and examination of it). When I bite down on it with certain foods, it feels uncomfortable, almost like it has moved, but apparently it hasn't.
