Most dentists feel that it is very important for their patients to understand the why’s and how’s of their treatment, and dentists often enjoy answering questions and explaining different options and procedures. Sometimes, though, a picture is worth a thousand words!
When your dentist prepares your tooth, the goal is usually to be as conservative as possible. While it may feel to your tongue that you have just a tiny little peg of a tooth remaining, the opposite is quite true! For an ideal tooth preparation, your dentist will remove only 1.5mm from the top of (occlusal) and around your tooth. In addition, there will be a 6’ angle around the sides of your tooth, which creates the maximum retention for your final crown.
The final impression captures a relief of your teeth, which is then used to create stone models of your teeth. These models are then used to fabricate your final crown. It is important that the impression includes the teeth next to, as well as opposing, the new crown so that the contacts and the bite can be correct. (You don’t want to “catch food” or “bang” your teeth together!)
This is a portion of a stone model based on final impressions. You can see that there is still plenty of strong tooth structure remaining!
”White” for your shade just isn’t good enough! Your dentist will always do a “shade check” so that your final crown will match the adjacent teeth.
Your final restoration might be a white zirconia-porcelain crown, a porcelain inlay, or a full-coverage gold crown.
