What are Dental Crowns?
Dental crowns cover a natural tooth like a cap which provides an entirely new surface and adds stability. If you need a 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.
Dental Crown Before & After Photos
What Are Dental Crowns Made From?
A dental crown can be made from gold alloy, dental composite, porcelain-fused-to-metal, or all porcelain. Since Dr. Marshall only uses metal-free and mercury-free products in her office, all of our crowns are all-porcelain only. Dr. Marshall also offers composite crowns but they are not as strong, especially on back teeth where a sturdy chewing surface is essential.
To find out how a 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.

Benefits Of Dental Crowns
Crowns are a more comprehensive option than dental fillings for correcting a number of common issues that affect a tooth. A crown is often an ideal solution for problems like:
- Broken or cracked teeth
- Teeth with severe wear
- Oddly shaped teeth
If you need multiple restorations to treat a health or cosmetic issue, crowns can also help anchor a dental bridge in place. Dr. Marshall also sees patients who have dental implants and are in need of a custom restoration to complete their newly revitalized smile.
How Are Dental Crowns Placed?
First Dr. Marshall will remove all damage and decay and any old filling that are 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 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 teeth. 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 Porcelain Crowns
Unlike metal restorations, dental porcelain can be fabricated to look just like your natural teeth. Dr. Marshall will customize your porcelain crown so it matches the adjacent teeth in size, shape and color so not even you will know the difference.
Porcelain crowns also have health benefits over their metal counterparts. The heavy metals used in traditional crowns can expose patients to mercury, a toxic substance with a multitude of negative effects on the body. Dr. Marshall takes every care to ensure her patients’ safety by practicing metal-free and mercury-free dentistry.
In addition to being indistinguishable from your natural teeth, other benefits of porcelain crowns include:
- Bonded directly to the tooth, making the tooth stronger
- Aesthetic perfection
- No temperature sensitivity like metal crowns
- The ability to create single-visit crowns on-site with our CEREC machine
Ceramic restorations traditionally require two visits to complete – one to take impressions so an off-site lab can fabricate the crown, and another to put the permanent crown in place. CEREC technology reduces the need for the off-site lab and the second appointment by fabricating custom crowns right in our office.
Dr. Marshall will take precise measurements of your tooth, and the CEREC machine will mill the porcelain into a crown that meets those specifications. This process can be completed in approximately one hour – significant time savings compared to the two weeks most dental laboratories require.
CEREC Single-Visit Crowns
In the past, a dental crown has required two visits to the dentist: one to prepare the tooth, make a mold and place a temporary dental crown, and a second visit to place the permanent, custom-made crown. Now, thanks to CEREC (Chairside Economical Restoration of Esthetic Ceramics), it is possible to have crowns placed in a single visit. Dr. Lindsey Marshall uses CEREC to make dental restorations easier, faster and more comfortable for all of her patients.
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 the 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.
How Long Do CEREC Crowns Take To Create?
Only one appointment is required for the creation and placement of CEREC crowns, and the appointment only takes about 30 minutes! Dr. Marshall will prepare your teeth and create the crowns in her office using the CEREC technology. Crowns created with CEREC only take about 20 minutes or less to create, allowing Dr. Marshall to prepare, create, and place your crowns in around 30 minutes total.
Do CEREC Single Visit Crowns Require Any Special Care?
CEREC crowns don’t require any specific care other than general, proper oral hygiene. You should treat your crowns as you would your normal, healthy teeth by continuing to brush and floss. This will not only increase the longevity of the crown but promote overall dental health.
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 will require 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 crowns and porcelain fillings, CEREC does a top-level job and saves you time in the dental chair.
What Happens If My Dental Crown Comes Off?
If the 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 Crown Need?
It needs the same daily brushing and flossing you give your natural teeth. The crown is part of the tooth, and just as bacteria can spread down between the gums and teeth, 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.
