Porcelain crowns have been used to restore problem teeth since at least the early 20th Century. Crown technology has gradually progressed from the early use of precious metals like gold or silver to more life-like porcelain crowns, often with a metal interior for added strength. Today, most crowns are all-porcelain, made with newer materials that not only look attractive but can endure under the pressures of daily chewing or biting.
While crowns are often part of restorations for missing teeth, they’re also commonly used to cap or fit over a viable tooth with structural or appearance problems. Here are 4 situations where a crown could improve a tooth’s form and function.
Traumatized teeth. A significant blow to the face or mouth could generate enough force to chip away or fracture a significant amount of structure from a tooth. If the root remains healthy and firmly attached within the jaw, however, a crown can replace the missing structure and restore the tooth’s function and appearance.
Root canal treatments. Root canal treatments remove infected or dead tissue within a tooth’s pulp chamber, its inner core, and the root canals. The procedure rescues the tooth but can in the process significantly alter the tooth’s structure and appearance. A crown not only restores the tooth but also provides added protection against further decay or tooth fracture.
Teeth with multiple fillings. We can effectively treat cavities caused by tooth decay by filling them. But with each filling we must remove more of the decayed structure and shape the cavity to accommodate the filling. After a number of times, a tooth may not have enough structure left to support another filling. If the tooth is still viable, a crown could solve this dilemma.
Abnormally developed teeth. Teeth sometimes don’t erupt in the jaw as they should and may be only partly visible. The tooth not only looks out of place but it can’t fully function like a normal tooth. Capping an abnormally developed tooth with a crown will help normalize it and allow it to blend in with surrounding teeth.

If your tooth sustains damage that compromises its structure — typically through decay or trauma — you have several options depending on the extent of the damage: One of them is a crown. This method saves the tooth and its root and completely conceals the visible portion of the tooth, or crown, under a natural-looking cap made to mimic as closely as possible the size, shape and color of the original tooth.
Crowns also hide imperfections in the original tooth like discoloration, chipping, fractures, excessive wear (from bruxism, or tooth grinding, for example), or abnormalities in the way the tooth formed. And they’re used following root canal treatments, which treat infected pulp at the center (canal) of a tooth root by removing the pulp and replacing it with an inert, rubber-like material.
Saving the natural tooth has long been the goal of dentistry because normal micromovements of the tooth root, which is suspended in its jawbone socket by elastic ligaments, stimulate the surrounding bone to rejuvenate. Without that stimulation, the bone continues to lose old cells, but no longer replaces them. Crowns are also designed to restore tooth function.
The function and location of the damaged tooth can determine what material the crown will be made of. If the damaged tooth is clearly visible when you smile, porcelain, the most realistic-looking material, is almost always used. If the tooth receives significant bite force, a stronger material is considered — either, a gold/porcelain combination, or a high-strength ceramic. If you are restoring a second molar, an all-gold crown may be considered.
With the advent of dental implants, saving a damaged tooth is no longer the only option for preserving the health of the bone surrounding the tooth root. The implant — a tiny biocompatible, titanium screw-like artificial root — is placed in the jawbone and is then capped with a natural-looking crown of course!

Want to know the exact wrong way to pry open a stubborn lid? Just ask Jimmy Fallon, host of NBC-TV’s popular “Tonight Show.” When the 40-year-old funnyman had trouble opening a tube of scar tissue repair gel with his hands, he decided to try using his teeth.
What happened next wasn’t funny: Attempting to remove the cap, Fallon chipped his front tooth, adding another medical problem to the serious finger injury he suffered a few weeks before (the same wound he was trying to take care of with the gel). If there’s a moral to this story, it might be this: Use the right tool for the job… and that tool isn’t your teeth!
Yet Fallon is hardly alone in his dilemma. According to the American Association of Endodontists, chipped teeth account for the majority of dental injuries. Fortunately, modern dentistry offers a number of great ways to restore damaged teeth.
If the chip is relatively small, it’s often possible to fix it with cosmetic bonding. In this procedure, tough, natural-looking resin is used to fill in the part of the tooth that has been lost. Built up layer by layer, the composite resin is cured with a special light until it’s hard, shiny… and difficult to tell from your natural teeth. Best of all, cosmetic bonding can often be done in one office visit, with little or no discomfort. It can last for up to ten years, so it’s great for kids who may be getting more permanent repairs later.
For larger chips or cracks, veneers or crowns may be suggested. Veneers are wafer-thin porcelain coverings that go over the entire front surface of one or more teeth. They can be used to repair minor to moderate defects, such as chips, discolorations, or spacing irregularities. They can also give you the “Hollywood white” smile you’ve seen on many celebrities.
Veneers are generally custom-made in a lab, and require more than one office visit. Because a small amount of tooth structure must be removed in order to put them in place, veneers are considered an irreversible treatment. But durable and long-lasting veneers are the restorations of choice for many people.
Crowns (also called caps) are used when even more of the tooth structure is missing. They can replace the entire visible part of the tooth, as long as the tooth’s roots remain viable. Crowns, like veneers, are custom-fabricated to match your teeth in size, shape and color; they are generally made in a dental lab and require more than one office visit. However, teeth restored with crowns function well, look natural, and can last for many years.
So what happened to Jimmy Fallon? We aren’t sure which restoration he received… but we do know that he was back on TV the same night, flashing a big smile.
