How do you prepare for a crown?
Before the process of making a crown begins, your dentist will anesthetize (numb) the tooth and the gum tissue around the tooth. Next, the tooth receiving the crown is filed down along the chewing surface and sides to make room for the crown.
What are the steps of PFM crown preparation?
Tooth preparation involves several distinct steps which include, creating the guiding grooves for incisal or occlusal reduction, reducing the labial or buccal surfaces and axial reduction of the lingual and proximal surfaces. After those chosen steps are complete, all prepared surfaces can be finished.
Is crown prep painful?
It will feel uncomfortable at first, but after some time it will feel and function just like a natural tooth! Like any other dental procedure, you may be wondering if there is any Pain after Crown Prep. After your treatment, you can expect the area to be sore for up to a week and sensitive to hot and cold.

How much should I reduce for PFM crown?
PFM crown preparation requires deep facial reduction to give enough space for metal and porcelain, and thus avoiding over contouring and poor esthetic which would inevitably occur when no enough tooth structure is removed. The amount of labial reduction is 1.5-2 mm.
How long should a crown prep hurt?
Following crown preparation, expect the treated area to be sore for 4-7 days. It also may be sensitive to hot and cold for 4-7 days if the treated tooth is still vital (does not have a root canal). Bleeding and discoloration of the gums around the tooth is normal and will subside after a few days with proper care.

What should I use to prepare my tooth for a PFM Crown?
It should extend into the proximal embrasures. The easiest way to shape the lingual surface of an anterior tooth is using a football-shaped diamond. Generally, for anterior teeth, a single guiding groove is placed in the central lingual surface. Preparation is completed with a fine grit diamond bur.
What kind of crowns are used for porcelain teeth?
Porcelain-fused-to-metal (PFM) crowns are among the most popular and reliable restorations. Using a cast metal substructure that is veneered with porcelain, this material closely mimics the appearance of a natural tooth.
How big should buccal preparation be for PFM crowns?
The buccal shoulder preparation should extend at least 1mm lingually to the proximal contact. The preparation should extend slightly further mesially than distally, as it is more visible. The occlusal surfaces of posterior teeth generally require 1.5 to 2 mm of clearance.
What are the guidelines for preparing a crown?
The crown must be sufficiently thick enough to hide the metal substructure and the opacious porcelain used to mask this alloy. When preparing a tooth, a systematic and organized approach helps to ensure the prep is correctly shaped.
