I just had a dental implant placed(#18) two weeks ago. Since the placement, I have been becoming increasingly more uncomfortable everyday. I have throbbing in my jaw, a horrid taste in my mouth, foul smell, and some sort of sore. I really want this implant to work, and so I'm wondering what the symptoms are for failure of dental implants? Is what I am experiencing normal? What would be abnormal and indicate failure? Thanks.
