making a crown


Thanks to modern dentistry, people are keeping their teeth longer, often for their whole lives.  Over the years the restorations (fillings) on teeth will be replaced  due to wear, fracture, recurring decay or endodontics (root canal) treatment.  For whatever reason they are replaced, the "fillings" become larger so the teeth and their "fillings" become more brittle, or may even fracture.  I often recommend crowns as the restoration of choice to protect these teeth from fracture and help keep them functioning longer than they might with just a "filling".

Crowns can be used to change the appearance of a tooth (or teeth if many are treated).  Colour, shape size and position can be changed to give the desired appearance.  Crowns can be fabricated from various materials, depending on the need for strength and/or esthetics and the patients desires.  Gold, porcelain bonded to gold or all ceramic (porcelain) crowns are all quite common.  All porcelain crowns are becoming very popular today. As a matter of fact these days I almost only make single crowns from solid ceramic material and use no metal like the crown you see rotating below.porcelain fuse to gold crown


  • Strong
  • allow damaged teeth to last much longer
  • aesthetic lifelike look
  • long lasting
  • protection from fracture
  • can improve the  colour of teeth
  • can improve the  shape and appearance of teeth


  • cost
  • some additional tooth structure needs to be replace to allow for a naturally sized tooth
  • porcelain can fracture if patient grinds their teeth
  • porcealin can wear opposing teeth
  • takes at least two appointments to fabricate

Crowns have been used by dentistry for decades but todays crowns offer better esthetics, durability and wear than ever.  The techology behind making crowns is amazing and research continues as does the improvement in how we fabricate crowns.
