Q. Hello, I had my first crown installed over a tooth that had broken. I was not in pain, it was a tooth that had been filled years ago. The tooth is a bottom, left, two teeth back from the canine. In any event, I have developed a slight lisp since the installation and it appears that my upper teeth are tilted (with the right side being lower). I went back to the dentist, he said he sees nothing wrong but that he would redo the crown if I wanted. He also offered the explanation of perhaps that perhaps air is now channeling differently through my mouth due to the width of the crown being less??? Is thsi a common occurence?
