Restorative dentistry has made incredible advancements in the technology of restorative dental materials, and there are more options than ever today for your dental crown or dental bridge. Zirconium and porcelain have proven to provide lasting strength and durability, exhibiting the most natural cosmetic dental restorations available today. Each tooth in each mouth is different, however, and in some cases, resin composite or metal alloy might be the choice recommended for you.
Metals are a common choice for dental crowns and dental bridges. Gold or palladium alloys, as well as chromium or nickel (base-metal) alloys can be excellent choices. Metal alloy crowns show the least “wear down” over years of use. They almost never chip, break or wear down opposing teeth. The primary complaint about metal alloy materials is that their color is metallic and thereby unnatural. They will not blend with the surrounding teeth, and as such, they are chosen more for back molars where they won’t draw attention.
Dental composite/resin materials are a popular choice that can be made to blend with the surrounding teeth, but they’ve been shown to wear down over time and are more prone to fractures and breaking than other materials.
Porcelain can be fused to metal to form a natural-appearing crown or bridge, and because of their appearance, are a good choice for front or back teeth. Over time, however, discoloration can appear along the gum line as the porcelain wears away, leaving a dark, unsightly line. The porcelain can be fused to zirconium, however, which eliminates the dark line and is a good cosmetic choice for front teeth.
Crowns and bridges can also be made from all-porcelain or all-ceramic materials. These materials are the best choice for natural-looking teeth of the types of dental crown and dental bridge materials available in restorative dentistry today. Because they contain no metal, they are excellent choices for patients with metal allergies. They tend to be weaker and less durable than materials containing metals, however.

Frequently Asked Questions
What are the different types of dental crown and bridge materials?
The main dental crown and bridge materials available today include metal alloys (gold, palladium, or base-metal alloys), dental composite/resin, porcelain fused to metal, porcelain fused to zirconia, and all-porcelain or all-ceramic. Each has different strengths in terms of durability, appearance, and cost. At Spring St. Dental in Bastrop, we help each patient choose the right material based on the location of the tooth, bite forces involved, cosmetic goals, and any metal sensitivities. Advances in zirconia and porcelain technology now make it possible to get restorations that are both strong and indistinguishable from natural teeth.
Which dental crown material is the most natural-looking?
All-ceramic and all-porcelain crowns offer the most natural appearance because they contain no metal and closely mimic the light-reflecting properties of natural tooth enamel. Porcelain fused to zirconia is also an excellent aesthetic option, it eliminates the dark line at the gum line that can sometimes appear with older porcelain-fused-to-metal crowns. These materials are particularly well suited for front teeth where appearance is most important. At Spring St. Dental, we also offer CEREC same-day crowns, which are milled from a single high-quality ceramic block for a precise, natural-looking fit.
Which crown material is the most durable?
Metal alloy crowns, particularly those made from gold or palladium are the most durable option in terms of long-term wear resistance. They almost never chip or crack and cause minimal wear on opposing teeth. However, their metallic appearance makes them most suitable for back molars where they are less visible. Zirconia crowns offer a strong middle ground: they are significantly more durable than traditional porcelain while still providing a tooth-colored appearance appropriate for any position in the mouth. Your Bastrop dentist will recommend the best balance of strength and aesthetics for your specific tooth.
What is the best material for a dental bridge?
The best dental bridge material depends on where the bridge is located and your priorities. All-ceramic and porcelain-fused-to-zirconia bridges are popular for front teeth because of their natural appearance and biocompatibility. Metal alloy bridges are extremely durable and are often chosen for back teeth where chewing forces are greatest. Porcelain-fused-to-metal bridges offer a compromise of strength and aesthetics, though over time a gray line may appear at the gum margin. At Spring St. Dental in Bastrop, we discuss all options during your crown and bridge consultation so you can make a fully informed decision.
Are there crown options that do not contain metal?
Yes, all-ceramic and all-porcelain crowns contain no metal whatsoever, making them an excellent choice for patients with known metal allergies or sensitivities. Zirconia crowns are also metal-free and offer exceptional strength comparable to metal options. At Spring St. Dental, we offer CEREC technology that allows us to mill a custom all-ceramic crown in a single visit, no metal, no second appointment, no temporary crown. This is a popular option for Bastrop patients seeking a metal-free restoration with minimal chair time.
