What is it?

A crown is a full coverage restoration that is cemented on top of prepared tooth structure to replace, restore or enhance a tooth to its previous shape and function. The crown is usually made out of a combination of gold, porcelain or ceramic.

Why do I need it?

A crown is usually recommended in the following circumstances:

1. Over an endodontically treated tooth.
2. To restore a tooth with a large filling to prevent tooth fracture.
3. Trauma.
4. To replace if there is recurrent decay.
5. To replace a broken crown.
6. To improve aesthetics.
7. To correct a bite.
8. Other cosmetic problems.

What does it involve?

Prior to initiating a crown

• Root canal therapy may be indicated.
• Crown lengthening may be indicated in some cases.

Preparing a crown involves:

1^st appointment.

1. Reducing the existing tooth structure in order to achieve adequate retention.
2. Taking impressions.
3. Fabricating a temporary crown.
4. Shade selection.

***In between the 1^st and 2^nd appointment a patient may choose to have custom staining completed by the lab.

2^nd appointment.

1. Removing the temporary crown
2. Trying in the crown.
3. Cementing the crown.

How successful is it?

Crowns are not permanent and may need to be replaced. Proper oral hygiene is critical to the long term success of a crown. Crowns are usually expected to last between 5-20 years. If the tissues surrounding the crown recede with time as patient ages a new crown may be needed for aesthetic reasons.

**Crowns usually have the longest lifespan of any restoration.**

What happens after?

Regular maintenance is critical, including a customized oral hygiene regiment and routine recall exams and cleanings which may range between 3-6 months as advised by the dentist.
