Cementation of a permanent crown

Typically, it takes seven to ten business days to make a permanent crown in a dental lab. Your dentist will schedule a cementing appointment for you before you leave the office after your dental prep procedure.

When you return to the dentist's office to cement the permanent crown, your dentist will begin your appointment by numbing the prepared tooth and surrounding tissue with a local anesthetic.

Even if the tooth has already been prepared, the dentist should clean it thoroughly before cementing the permanent crown. If you have a root canal on a prepared tooth, you probably don't need a local anesthetic.

Standing crown

When the prepared tooth is completely numb, the dentist will remove the temporary crown from the tooth. All temporary cement is removed from the tooth and the tooth dries completely. Then your dentist will try on the permanent crown on the tooth.

With a piece of dental floss, your dentist will also check the contact between the crown and the adjacent teeth to ensure perfect contact between the teeth. Too close or no contact creates a problem for you in the long run.

Too much contact will cause problems flossing. The lack of contact between the teeth will prevent food from getting stuck between the teeth, which can lead to cavities.

If the contact is too tight, your dentist will cut a small amount of the adjacent tooth instead of the crown. If there is no contact, the crown may need to be sent to the lab for rework.

When the dentist is satisfied with the fit of the crown, the final cementation process begins. This process is to keep the tooth completely isolated from saliva or water in the mouth.

Cotton swabs can be placed on both sides of the tooth to keep the area dry. When the tooth is isolated and dried, a desensitizing agent can be applied to the tooth. The desensitizing agent will help with any post-operative tooth sensitivity.

Your dentist will apply an adhesive material to the prepared tooth. Some adhesives require a light to cure the material to anchor the material. Once the adhesive has cured, the dental assistant will fill your permanent crown with cement and gently hand the crown over to your dentist.

Your dentist will place the crown on the tooth and remove any excess cement that is coming out from under the crown. Depending on the cement selected, the light can be used again to fully set the cement.

Dental floss will be used to remove excess cement between the teeth and a dental scaler will be used to remove excess cement around the tooth and below the gum line.
