Depending on the material used, three types of dental crowns exist: (#1) Porcelain Crowns, (#2) Porcelain-Fused-to-Metal Crowns, and (#3) Gold crowns. The three types are indicated in different situations because of their respective advantages and disadvantages:
1. Porcelain Crowns
Porcelain Crowns are dental crowns made completely of porcelain. Porcelain is an excellent material, since it is both extremely strong and aesthetic. Porcelain’s color and translucency closely matches enamel, making porcelain crowns very natural looking, creating beautiful crowns.

2. Porcelain-Fused-to-Metal Crowns
- Porcelain-Fused-to-Metal Crowns have metal inside and porcelain outside. The metal inside adapts perfectly to the tooth and provides strength and resistance to biting forces. The porcelain outside provides the beautiful appearance of the crown, matching the color and shape of your other teeth.
- The main advantage of Porcelain-Fused-to-Metal Crowns is their strength and durability. Due to the high force on molars while chewing, Porcelain-Fused-to-Metal Crowns are typically recommended when a dental crown is needed on a molar.
- The main disadvantage of a Porcelain-Fused-to-Metal Crown is that the metal can sometimes be seen through the porcelain close to the gum line, creating a grey line or grey shadow near the gums. This disadvantage is an aesthetic issue and does not affect your gums or the function of the crown.
3. Gold Crowns
Gold crowns are obviously made of gold, but they are rarely used anymore (despite their high quality) because of their poor aesthetics.
A special type of dental crown is an Implant Crown. An implant crown is a dental crown that is placed on top of an implant to replace a missing tooth. A dental implant is a titanium screw that is placed in the jaw bone in the area of a missing tooth. Then, an implant crown that looks and feels like a natural tooth is placed on top of the implant screw to replace the missing tooth.

A little about me and my experiences with dental crowns:
After graduating from Tufts Dental School, I completed a residency at Boston City Hospital. Following the residency, I worked in a practice near Boston while teaching at my dental school for a few years. My wife Joanne and I then decided to move to south Florida, where I have practiced for the past twenty-five years. Over this time, cosmetic dentistry has become my passion, especially making beautiful dental crowns. In the office, we make sure that every crown blends absolutely perfectly with our patients’ natural teeth. If the color of a dental crown is slightly off, we add a little color and bake the crown in our porcelain oven until it is the perfect shade. Also, we want every crown to look gorgeous and last as long as possible, so we only use the highest quality porcelain. If we are making a porcelain-fused-to-metal crown, we only use high precious metal. In addition, to make every crown, we confidently believe that we use the best dental laboratory in the country.
