What are Dental Crowns?
Dental crowns cover a natural tooth like a cap, providing an entirely new surface and added stability. If you need a tooth crown, cosmetic dentist Dr. Lindsey Marshall uses advanced technology and quality materials to craft durable dental restorations for patients in and around the Philadelphia area.
To find out how a tooth crown can help you, please call the office of Lindsey Marshall, DMD, today at (610) 649-0696. Dr. Marshall welcomes patients from Philadelphia and other Main Line communities to her office in Ardmore, Pennsylvania.
Advantages of Dental Crowns
Crowns are a more comprehensive option than dental fillings for correcting a number of common issues affecting a tooth. A crown is often an ideal solution for problems like:
- A broken or cracked tooth
- A tooth with severe wear
- Severe stains
- An oddly shaped tooth
If you need multiple restorations to treat a health or cosmetic issue, crowns can also anchor a dental bridge in place. Dr. Marshall also sees patients who have dental implants and need a custom restoration to complete their newly revitalized smile.

Dental Crown Procedure
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 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.
What are Porcelain Crowns?
A porcelain crown is a glass-like ceramic not unlike delicate china. By itself it is brittle, but once bonded to your tooth it is hard, durable, and visually pleasing. It contains no metal.
Whatever a crown is made of must be hard enough to withstand chewing forces for years, yet not so hard that it will wear down the opposing tooth. Gold alloy fulfills those requirements, but looks unattractive. Dental porcelain also fulfills them and has the added benefit of looking like tooth enamel.
Tooth enamel and porcelain are not transparent, but they are semi-translucent. Some light penetrates them and some bounces off. The light that penetrates reflects off the layer beneath the surface. In the case of enamel, that is the dentin layer. In the case of porcelain, it is the dental cement attaching the porcelain restoration. By absorbing some light and reflecting some, enamel and porcelain achieve a similar pearly sheen.
Porcelain is also stain-resistant so that your dental crowns, or other porcelain restorations such as porcelain veneers or porcelain fillings, will remain a clean white color for their lifetime.
Benefits of All-Porcelain Tooth Crowns
Along with the health benefits of dental porcelain and the speed with which our advanced technology creates custom tooth crowns, other key advantages over traditional metal crowns include:
- A porcelain crown looks like a real tooth, unlike metal restorations
- Dental porcelain tends to be as durable as natural tooth enamel
- If your gums recede with age, no unbecoming dark streak will form at the gum line
- Greater stability – the ceramic won’t change shape when exposed to hot and cold
- With CEREC, you only need one appointment – no waiting several weeks for a lab to fabricate your crown
Porcelain is also stain resistant, meaning not only will the crown match the natural shade of your teeth but it will retain that lifelike color throughout the lifetime of the restoration.
CEREC Single-Visit Crowns
With CEREC technology, we can make your tooth crown here in our office.
CEREC is one of the most advanced and recent developments in dental technology. Most dental offices use a dental laboratory to make crowns. That means you must come for two visits: one to prepare the tooth and assemble the data for the lab and a second one to bond the crown. There is a waiting period of several weeks in between visits, during which you must wear a temporary crown and take care that it does not come off.
Because we have a CEREC system, you can have your crown made and placed in just one visit.
CEREC is a porcelain milling system with an advanced computer system, CAD-CAM software, and a milling unit. After Dr. Marshall has all the data for making your crown and has entered it into the CEREC system, we will mill the crown here while you wait for a few minutes.
The Color of Dental Crowns
Porcelain comes in different shades, and Dr. Marshall will choose one to match your tooth enamel. Since some light passes through porcelain, the shade of dental cement used to attach your crown will also affect your crown’s precise color. Therefore, when she attaches it, Dr. Marshall can tweak its color by her choice of cement.
If you intend to have a teeth whitening treatment, you should do this prior to having your crown made so Dr. Marshall can match your crown to your new tooth color.
To use CEREC technology well requires dedication and time. Dr. Marshall does not use it for dental bridges or porcelain veneers, as she feels her dental lab technician can do an even better job for those restorations. But for tooth crowns and porcelain fillings, CEREC does a top-level job and saves you time in the dental chair.
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.
