Crowns are used for restoring cracked, chipped, or worn-down teeth. A crown, also called a cap, covers a damaged tooth with an artificial material. It may save your existing tooth, instead of completely replacing the tooth. Your dentist will be able to tell you if a crown is right for you, but here are some answers to common questions to help you decide.

Why would I need a crown?

Crowns are most often used in the following situations:
• If a significant amount of decayed matter has been drilled out and filled, and the remaining enamel isn’t strong enough to support chewing or biting.
• If support is needed for a bridge.
• If a tooth is about to break.
• If a tooth is misshapen or badly discolored, crowns can improve appearance.

What does getting a crown involve?

Your dentist will numb the area, and trim off about 25% of the tooth. An impression will be made for use in creating a temporary crown in the dentist’s office and a permanent crown at a lab. A temporary crown is often used while the permanent one is being developed. Temporary crowns aren’t meant to last as long, so a permanent one needs to be placed that will be stronger and last longer. Once received, your dentist will place the crown to ensure proper fit. Then the crown will be cemented into your mouth.

What are crowns made of?

Temporary crowns are made in the dentist’s office with stainless steel or acrylics. Permanent crowns are made in a lab using resins, porcelain, metals, or combinations of these materials. Your dentist can make recommendation of the type of crown that would work best for you.

How long will crowns last?

Crowns typically last at least seven years, but in many cases they last much longer. Some last as much as forty years. To increase the life of your crown, you should practice good oral hygiene. Also, avoid chewing excessively hard foods because they can damage your crown.
