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.
Do You Need a Tooth Crown?
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.

Tooth Crown Treatment
Dr. Marshall is proud to practice metal-free dentistry to protect patients from potentially toxic substances. While many dentists use crowns made from gold and other alloys, all of our crowns are made from durable ceramic materials.
Porcelain crowns have a number of advantages over their metal counterparts. One of the major benefits is that your tooth crown will be fabricated in just a single visit.
Our office near Philadelphia uses a device called a CEREC machine to create custom porcelain dental crowns. Using precise measurements of your teeth as a blueprint, the machine mills the ceramic material into a custom crown that Dr. Marshall can immediately fit on your tooth. The entire process takes less than an hour.
What are Porcelain Crowns?
Porcelain Crowns 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.
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 Your Crown
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.
