Crowns

Crowns are full coverage restorations that are used to cover a tooth that is likely to break, or is too broken down to be restored with a filling. They are most commonly done after root canal treatment, or when a large filling wears out. Even after a filling is put in a large cavity, a tooth is more likely to break. Keep in mind that the jaw muscles are the strongest in the human body. Teeth are subjected to tremendous pressures. Crowns ride over the weakened tooth, providing strength and protecting the tooth against breakage. A broken or cracked tooth is a far more serious matter and much more difficult to treat. Crowns prevent this, as well as making for a nice smile! 

 

Crowns can be done in a single appointment with our new CEREC 3D software and milling unit.

First we will administer an anesthetic and prepare your tooth for the restoration, removing decayed and weakened tooth tissue.  This preparation is just like we would do for many other restorative techniques.

Then, we take an Optical Impression of the prepared tooth.  Instead of filling a tray with impression "goop" that you must bite into and hold in your mouth until it hardens, we coat the tooth with a non-toxic, tasteless powder.  A camera is then used to take a digital picture of your tooth.  This whole Optical Impression process only takes a minute or two.

CEREC 3D SoftwareNext, the CEREC machine helps us create the restoration for your tooth.  The CEREC 3D software takes the digital picture and converts it into a 3-dimensional virtual model on the computer screen.  We then use our dental expertise to design the restoration using the CEREC 3D computer program.  Within a few minutes, and a few clicks of a  button, the restoration design data is sent to a separate milling machine in the office.  A ceramic block that matches your tooth shade is placed in the milling machine.  About 10 - 20 minutes later, your all-ceramic, tooth-colored restoration is finished and ready to bond in place.  Finally, we try the restoration in your mouth to ensure proper fit and bite.  The restoration is then polished and bonded to the prepared tooth.  Your tooth is restored with no "temporary" or return trip necessary.  All of this is done in a single appointment!  Ask us about CEREC today.

 

Some crowns still require two appointments to restore the tooth. In the first any decay is removed from the tooth and it is shaped to accept the crown. Then an impression is made of the tooth for use in fabricating a crown. Between the two visits the crown is made, usually of high-strength porcelain over gold alloy, all ceramic material, or gold. During this time a temporary crown is worn. In the second visit this temporary is removed. Then the permanent crown is adjusted as needed and then cemented in place.
