Dental Crown Procedures: What To Expect

This restorative dental treatment option can help the function, strength and appearance of a crooked, discoloured, damaged or decayed tooth. Today, our dentists in Nepean share what you can expect during a dental crown procedure. 

What is a Dental Crown?

Also referred to as a cap, a dental crown is a dental restoration that covers (or 'caps') a tooth to restore its size, shape and colour. 

Dental crowns can help the appearance, strength and function of a damaged or decayed tooth that would otherwise need to be replaced or extracted. 

Plus, dental crowns can be used for cosmetic reasons such as to cover a discoloured or uneven tooth, and to change the overall appearance of your smile. 

Because they are often made of porcelain (a material that strengthens and protects the remaining structure of the tooth), crowns are quite strong. 

The Crown Procedure

At least two appointments at your dental office are typically needed to replace a dental crown. Once the dentist has determined you need a crown, here's what you can expect during each appointment. 

The First Appointment

In order to prepare for a crown, your dentist will first examine your mouth and then prepare the tooth.

To prepare the tooth, your dentist will file down and remove part of the outer layer of the tooth. Next, they will take an impression of the trimmed tooth and the surrounding teeth, and place a temporary crown over the tooth to protect it. The temporary crown is placed using temporary cement so that it can come off easily when the permanent crown is ready.

Your dental office will send your unique tooth impression to a dental laboratory to make your permanent crown, which may take several weeks. 

Using your impression, the laboratory technician is able to examine all aspects of your bite and jaw movements and sculpt a crown just for you. Your dentist will also be sure to determine the shade of your teeth to help the technician make a crown that will match the colour of the rest of your teeth. 

The Second Appointment

Once the crown is ready, you’ll return to your dental office for the second appointment. During this visit, your dentist will remove the temporary crown and place the permanent crown on your tooth.

The permanent crown is first placed on the tooth and inspected for acceptable fit, bite and smooth margins. After any necessary adjustments have been made, the crown is cemented with permanent cement or dental glue.

Caring for a Dental Crown

With the proper care, dental crowns can last on average from 10 to 20 years. They are still subject to damage, so it is important to take care in brushing and flossing around crowned teeth to prevent them from needing to be replaced too soon.
