All-ceramic crowns (or "porcelain" crowns) will provide you with the most natural-looking esthetics, but one should know that there are several types of porcelain available to clinicians today, each type having advantages and/or disadvantages. The following must be considered prior to the placement of a generic "ceramic" crown:
Where will the crown be placed (in front of the mouth or in the back)?
Will the ceramic crown be adhered or cemented onto natural tooth structure, a post, or an implant?
Is parafunction present (grinding, clenching, etc.)?
Are any habits present (nail-biting, gum-chewing, etc.)?
Today's ceramics are exceedingly strong and can be placed in the front of the mouth or in the back of the mouth. If you're concerned about longevity, be sure to ask your dentist what type of ceramic he/she is placing. MORE IMPORTANTLY, make sure that your dentist is up-to-date with adhesive bonding, which is the process used to adhere ceramic crowns to tooth structure.
