The right hand side, 2nd last tooth filling drop out partly n my tongue can feel some sharp thing (as shown in the pic). I had went to see dentist and had did x-ray. It has not affect my nerve but can see that tooth already no life as it won't feel pain even the dentist try to hit it. Dentist give me 2 choices, 1st choice is to remove this tooth, 2nd, she will remove the nerve n plant a tooth. I do not want to remove it as it still ok and no pain. I just wan to make it smooth n fill the drop out area. Any advice on this matter?
