Q. I have asked my dentist if the 6 caps can be replaced as they are showing the metal at the top of my gums, they have said that the posts are very big and their is a chance that the roots can break, Is their any thing that can be done, I have also got 5 teeth missing lower left, I have tried to wear the denture, it makes me gag, I have problems eating with them, can this be sorted out, And if so what can be done and what would the cost of this approx be.
