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.
