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.

In real life he was a hard-charging basketball player through high school and college. In TV and the movies, he has gone head-to-head with serial killers, assorted bad guys… even mysterious paranormal forces. So would you believe that David Duchovny, who played Agent Fox Mulder in The X-Files and starred in countless other large and small-screen productions, lost his front teeth… in an elevator accident?
“I was running for the elevator at my high school when the door shut on my arm,” he explained. “The next thing I knew, I was waking up in the hospital. I had fainted, fallen on my face, and knocked out my two front teeth.” Looking at Duchovny now, you’d never know his front teeth weren’t natural. But that’s not “movie magic” — it’s the art and science of modern dentistry.
How do dentists go about replacing lost teeth with natural-looking prosthetics? Today, there are two widely used tooth replacement procedures: dental implants and bridgework. When a natural tooth can’t be saved — due to advanced decay, periodontal disease, or an accident like Duchovny’s — these methods offer good looking, fully functional replacements. So what’s the difference between the two? Essentially, it’s a matter of how the replacement teeth are supported.
With state-of-the-art dental implants, support for the replacement tooth (or teeth) comes from small titanium inserts, which are implanted directly into the bone of the jaw. In time these become fused with the bone itself, providing a solid anchorage. What’s more, they actually help prevent the bone loss that naturally occurs after tooth loss. The crowns — lifelike replacements for the visible part of the tooth — are securely attached to the implants via special connectors called abutments.
In traditional bridgework, the existing natural teeth on either side of a gap are used to support the replacement crowns that “bridge” the gap. Here’s how it works: A one-piece unit is custom-fabricated, consisting of prosthetic crowns to replace missing teeth, plus caps to cover the adjacent (abutment) teeth on each side. Those abutment teeth must be shaped so the caps can fit over them; this is done by carefully removing some of the outer tooth material. Then the whole bridge unit is securely cemented in place.
While both systems have been used successfully for decades, bridgework is now being gradually supplanted by implants. That’s because dental implants don’t have any negative impact on nearby healthy teeth, while bridgework requires that abutment teeth be shaped for crowns, and puts additional stresses on them. Dental implants also generally last far longer than bridges — the rest of your life, if given proper care. However, they are initially more expensive (though they may prove more economical in the long run), and not everyone is a candidate for the minor surgery they require.

Although oral cancer isn't the most prevalent among metabolic diseases, it is one of the most deadly with only a 50% survival rate after five years. That's because it can be difficult to detect in its early stages when treatment is most effective.
That's why prevention to reduce your chances of oral cancer is so important. Many people know quitting tobacco products, including smokeless varieties, and moderating alcohol consumption are key to any prevention strategy. But there's one other factor you should also consider: your diet.
We've learned quite a bit in the last few decades about how certain foods we eat contribute to the cancer disease process. Cancer seems to originate when elements in the body or environment (known as carcinogens) damage DNA, our unique genetic code, on the cellular level. For example, a class of chemicals called nitrosamines is a known carcinogen: we often encounter it in the form of nitrites used to preserve meat (like bacon or ham) or as byproducts in beer, seafood or cheese.
Another form of carcinogen is the unstable molecules produced during normal cellular function called free radicals. But our bodies have a natural neutralizer for free radicals called antioxidants. We obtain these substances in our food in the form of vitamins and minerals. While you can also ingest these in the form of supplements, the best way to obtain them is through a diet rich in plant-based food, particularly fruits and vegetables.
So in addition to lifestyle changes like quitting tobacco or moderating alcohol consumption, make sure your diet is a healthy and nutritious one. Limit your intake of processed foods (especially meats) and increase your portions of fresh fruits, vegetables and dairy products.
And don't neglect practicing effective brushing and flossing each day, along with regular dental cleanings and checkups. All of these healthy practices will greatly decrease your chances for life-threatening oral cancer.
