How long does it take to put a crown on a tooth and how is a crown placed?

Placing a permanent dental crown typically takes two dental office visits. 

On the first visit, the dentist will numb the tooth and surrounding gum tissue to shape the biting surface and sides of the tooth to allow space for a new crown. if the tooth is decayed or too small to hold the crown, the dentist will “build up” the tooth to hold the crown. 

Once the tooth is shaped, the dentist will then make an impression of the tooth to make the custom crown. The dentist will make a temporary crown to cover the prepared tooth until the permanent one is ready. The dentist may ask you to refrain from chewing gum or sticky substances while your temporary crown is in place. If a porcelain or porcelain fused to metal crown is being placed, the dentist will also have to determine the shade of porcelain to match the surrounding teeth.

On the second visit, the dentist may numb the tooth and surrounding gums in order to cement the crown in place. After the new crown has been placed, you may need a follow-up appointment to adjust the crown so it fits comfortably. 

Some new technology allows crowns to be produced in one day. 

Some dental offices may offer faster "same-day" crown services, but the availability will vary be office. Ask your dentist for more information.
