Frequently Asked Questions
What does a dental crown accomplish?
A crown is a tooth covering that gives new surfaces to that tooth and is used to restore a tooth that by itself is unstable and weak. The crown could:
- Strengthen a tooth threatened by a large filling
- Protect a cracked tooth
- Restore a chipped tooth
- Renew a severely worn tooth
- Provide new surfaces to cover deeply discolored surfaces
Teeth crowns can also be part of a bridge: Two neighboring healthy teeth are given crowns to hold the replacement tooth.
What materials is a dental crown made from?
A dental crown can be made from gold alloy, dental composite, porcelain-fused-to-metal, or all porcelain. Philadelphia cosmetic dentist Dr. Lindsey Marshall uses only metal-free, mercury-free products in her office, so we offer only all-porcelain crowns. Composite crowns could be done but they are not as strong, especially on back teeth where a sturdy chewing surface is essential.
How is a crown procedure done?
First Dr. Marshall will remove all damage and decay and any old filling that has worn out. After doing a thorough preparation, she will take an impression and photographs of the area and input them with measurements and other data into our CEREC systems. While you wait for a brief time, your crown will be milled according to Dr. Marshall’s specs. She will attach it with a temporary bond to test your bite and ask you how it feels. When you are both satisfied, she will bond it permanently to your tooth.
What happens if my crown comes off?
If the tooth crown is properly done by a qualified dentist, it should not come off. Dr. Marshall uses the best bonding material and high-quality porcelain, and has over 6 years of experience placing crowns. A temporary crown might come off, but since we have CEREC technology and can make your crown while you wait, we do not always need to give you a temporary crown.
What daily care does a dental crown need?
It needs the same daily brushing and flossing your give your natural teeth. The crown is part of the tooth, and just as bacteria can spread down between the gums and a tooth they can also spread between the gums and a crown. If you remove plaque and food particles thoroughly and regularly and come for your routine check-ups and professional cleaning, your dental crown should last many years — even decades.
