This question refers to central upper incisors (the 2 front upper teeth). The reason I ask is because part of my teeth (lingual side) is nothing but dentin, the labial side as well as the lateral edges still have a good amount of enamel. Also, how much room do I need behind these teeth and the lower ones to make sure there is sufficient room for a porcelain crown - when I bite down that is? Thank you.

Answer: Are Porcelain Crowns a good chice to adhere to dentin.
The three porcelain systems you mentioned differ in chemical composition. Procera, the oldest is, is aluminum oxide with conventional feldspathic porcelain fired over the alu-oxide core. It is indicated in single tooth applications only and has largely been replaced by Emax which is lithium...
Yes, it is possible to drill through an EMAX crown. need a special bur ideally an an adept clinician with good skills. There is always the risk of weakening the porcelain and possible fracture, but that is pretty rare.
Without any xrays, it is hard to say, but I can suggest you change that crown and you will not need to touch the gums,that way they would be even,and looking healthy,taking x rays in different angles would help, to see the crown adjustment also, Hope this helps.
