What is a crown?

A crown is a cover or a cap that your dentist will put on a tooth. The crown restores the tooth to its standard size, shape and function. The purpose of this procedure is to make the tooth stronger and improve its aesthetics, thus restoring the tooth and protecting it from further damage.

Who needs a crown? 

We will recommend a crown if you:

- have a cavity that is too large for a filling

- have a missing tooth and need a bridge 

- need to cover a dental implant

- have a tooth that is cracked, worn down, or otherwise weakened

- have had a root canal treatment 

- want to cover a discoloured or poorly shaped tooth


How is a crown done?

  1. Your doctor gives you a local anesthetic.

  2. To make room for the crown, he files down the tooth that needs restoration.

  3. Your dentist will take an impression of the filed-down tooth and nearby teeth. This procedure will determine the shape of your permanent crown and using restorative material (the material used for fillings), we will build it. The final crown will be the right shape for your mouth.

  4. Until your final crown is ready, your dentist places a temporary crown over the tooth that needs the restoration. This temporary cap will protect your tooth until the final crown is ready. A temporary crown may not have the same shape and colour as a final crown.

  5. On your next visit, the dental doctor takes off the temporary crown and puts on the final one. We make sure the crown is the right fit, shape, colour and bite. If it is, your dentist cements it into place.


Different types of crowns

Crowns are made from various types of materials. Depending on which tooth needs a crown, Your dentist will suggest different materials or combinations of materials that are right for you.

  • Metal crowns are made of gold. They generally last a long time and won’t chip or break. They tend not to wear down your opposing natural teeth. However, the gold colour does not look natural, particularly on front teeth.

  • Composite crowns look natural. They won’t chip as easily as porcelain crowns, but they tend to wear more quickly from chewing. Tooth brushing tends to remove the highly polished surface of composite crowns, and this causes them to stain more easily.

  • Porcelain crowns look the most natural. They are more brittle than metal or composite and may chip more easily. Because of this, they are not usually placed on back teeth.

  • Porcelain-fused-to-metal crowns look natural and are stronger than porcelain or composite crowns. They won’t chip as easily as porcelain or ceramic crowns. However, depending on their design, the metal may show if your gums are thin or shrink.


What else should I know?

Crowns may not be as strong as your natural teeth. So like your natural teeth, remember not to bite down on hard objects or use your teeth to open or cut things.


Instructions after We Place a Temporary Crown


  •  Please do not chew on the temporary crown for approximately 30 minutes.

  • With the temporary crown, please refrain from chewing anything chewy or sticky (gum, taffy), and hard foods on that side.

  • Also, please avoid eating popcorn or nuts during this time.

  • Rinse with saltwater.

  • If the temporary crown does happen to come off, you can try to put it back on yourself with some toothpaste or denture adhesive. The crown only goes on one way, so if your bite feels okay, then it is on correctly.

  • Please call us to have the temporary crown re-cemented at your earliest convenience if this does happen.

  • Please brush the temporary crown like your other teeth, but avoid flossing around that tooth.

  • If something should get stuck between the teeth, floss through the contact and pull the floss out the side to avoid hooking the margin of the temporary crown and pulling it off.

  • Please return at your appointed date to have the permanent crown cemented.   


Instructions after We Cement a Permanent Crown:

  • After the dentist cements your new, finalized crown appointment, wait one hour to eat.

  • Avoid hard or sticky foods for a few hours.

  • Resume regular brushing/flossing habits, and follow any special hygiene instructions given by your dentist

  • The gums around the tooth may be sore for 2-3 days following the procedure. Advil or Tylenol is best to take if this does occur.
