question: A few weeks ago I got a new crown. Last molar in bottom back left side. I cannot afford to loose the tooth. He used the new technology. Two hours and all done. But it sits too low. He has tried to adjust my bite by taking a little off my front bottom teeth but it still is too low. Can the crown be built up with porcelain while in my mouth. I am afraid of taking it off and redoing it because the tooth has a crack in it.
