Types of Dental Crowns

Dental crowns are great restorative treatment for a tooth that’s chipped, badly decayed or otherwise damaged. They also provide support for a weak tooth atop a dental implant or serve as a cap after root canal therapy.


Before fitting a crown, dentists will take a mold of the existing tooth (either manually with impression paste or digitally with a scanner). Then they’ll shape the tooth to fit the crown and match it to the color of the surrounding teeth.

Porcelain Fused to Metal Crowns

Porcelain fused to metal crowns have been around for decades and are the most commonly used dental crown type. They are a durable restoration that is trusted by dentists all over the world and patients alike. These crowns have a metal alloy frame that adds strength so they can withstand the pressure of chewing, and they have a porcelain layer on top which helps them to blend in with natural teeth.

These crowns require two separate dental appointments, because your dentist needs to prepare the tooth before they can put in the PFM crown. Then, they will need to take a dental impression or oral scan, so they can send it off to a lab where the crown will be made. In the meantime, your dentist will place a temporary crown on the tooth. During the second appointment, your dentist will check the fit and adjust the crown as needed before they can permanently attach it to the tooth.

One downside of these crowns is that the metal may contact your gum tissue. This can cause sensitivity and irritation, especially if the crown is fabricated using non-precious or semi-precious base metal alloys like silver, cobalt-chrome, nickel, etc. If you choose to use a higher quality PFM crown that has more noble metal content, like gold, this may help to avoid this issue.

Modern alternatives to PFM crowns include ceramics like Emax and Zirconia that are stronger and look more life-like. These are typically milled with a computerized machine to precise specifications which can make them more accurate and ensure the best fit. These types of crowns are also more durable and can last a lifetime with proper care. They are an excellent choice for molars and premolars where durability is of the utmost importance.


BruxZir has been the choice of many dentists who are replacing PFM crowns with these new, esthetic and durable restorations. Unlike porcelain crowns, which are susceptible to chipping and cracking, BruxZir is much stronger and will not break under normal chewing forces. It is also more hygienic, as it is not porous like porcelain and will not collect plaque as easily.

These tooth-colored restorations are a great choice for those who grind their teeth and need a strong, esthetic option. They can be made of ceramic or titanium. Howard Beach Dental Associates specializes in both types, which are known for their strength and durability.

When choosing between IPS e.max and BruxZir, the decision usually depends on two main factors: durability and esthetics. BruxZir zirconia has been scientifically tested to demonstrate high survival rates against some of the toughest clinical forces. In addition, it is a monolithic material that can be used for a variety of indications, including crowns, bridges, inlays and onlays, screw-retained implant restorations and full-arch implant prostheses.

Each BruxZir restoration is fabricated using CAD/CAM technology from an impression or digital scan of the patient’s mouth and milled to the exact size. The finished restoration is then sintered for 9 hours, sandblasted to smooth the surface, then stained and glazed to create a natural appearance.

While some patients will experience gum swelling and tenderness following the placement of a BruxZir crown, over-the-counter pain relievers should be sufficient to control any discomfort. BruxZir crowns are typically more durable than porcelain crowns, but the best way to determine whether they will work for you is to visit Howard Beach Dental Associates for a consultation.

Ceramic Crowns

Dental crowns are used to repair or protect a tooth that has suffered from damage from decay, root canal treatment, injury, or a large filling. They are also used as cosmetic treatments to change the shape of a tooth. There are several types of crowns that vary in price, materials, and procedures. Most dental insurance plans cover most of the cost of a crown depending on the type of plan and the dentist.

A ceramic crown is made from an impression of the damaged tooth that’s taken and molded by a ceramist to make a cap for the tooth. It is a tooth colored restoration that is very strong and aesthetically pleasing. It is bonded to the tooth using resin bonding. This method requires minimal occlusal and axial reductions which helps preserve more of the original tooth structure. This is a great option for patients with sensitive teeth or those who have a metal allergy.

Zirconia crowns are a newer crown material that’s a cross between porcelain and metal. They’re stronger than PFMs and have a higher translucency similar to the look of real teeth. Zirconia can be crafted at the same office as PFMs but require less tooth removal and have a lower likelihood of breakage. This type of crown is a good choice for people who clench their teeth because the strength can help prevent wear and tear.

If you’re considering getting a dental crown, talk to your dentist about the different options and the costs involved. They will be able to give you an estimate and help you decide which crown is right for your needs. They may even offer payment plans to help you afford the procedure. Be sure to choose a dentist who works in-network with your insurance so you can get the most out of your coverage.
