How is it possible for a dental crown to be the wrong size if the lab has a mold of my mouth?

Many factors go in to creating a crown.  It is necessary to have a very skilled ceramist to ensure a natural and precise result.  Don't have the crown permanently placed until you are happy.

There are so many reasons a crown could not fit, for example, there's a percentage of expansion or shrinkage that happens with not just the impressions taken, but also the stone models, which can cause fit issues.  Don't be nervous about the turn out, just make sure you're able to see it before it's permanently put in.

There are more than a dozen factors involved in making a crown.  If a dentist is skilled, allows adequate time, uses the best materials, and the best lab, every crown he cements permanently will fit well, look good, and last indefinitely.  Unfortunately dental insurance has created a downward pressure on fees for crowns and for that  matter all dental work.  The result is dentists are focused more on doing dental work faster and cheaper rather than on quality and durability.  Our office is a fee for service office where you can use your dental insurance, but the dentist has not signed up with the insurance company and therefore can focus on excellence.  We guarantee all our work indefinitely.
