Dental crowns are an essential means for restoring damaged or unattractive teeth. A well-crafted crown not only functions well, it looks and blends seamlessly with the rest of the natural teeth.
Crowns are artificial caps that cover an entire visible tooth, often used for heavily decayed or damaged teeth or as added protection after a root canal treatment. Most crowns are produced by a dental lab, but some dentists are now creating them in-office with computer-based milling equipment. On the whole, the various crowns now available function adequately as teeth—but they can vary in their appearance quality.
In the early to mid 20th Century the all-metal crown was the standard; but while durable, it could be less than eye-pleasing. Although more life-like dental porcelain existed at the time, it tended to be brittle and could easily shatter under chewing stress.
Dentists then developed a crown that combined the strength of metal with the attractiveness of porcelain: the porcelain fused to metal or PFM crown. The PFM crown had a hollow, metal substructure that was cemented over the tooth. To this metal base was fused an outer shell of porcelain that gave the crown an attractive finish.
The PFM reigned as the most widely used crown until the mid 2000s. By then improved forms of porcelain reinforced with stronger materials like Lucite had made possible an all-ceramic crown. They’re now the most common crown used today, beautifully life-like yet durable without the need for a metal base.
All-ceramics may be the most common type of crown installed today, but past favorites’ metal and PFM are still available and sometimes used. So depending on the type and location of the tooth and your own expectations, there’s a right crown for you.
However, not all crowns even among all-ceramic have the same level of aesthetic quality or cost—the more life-like, the more expensive. If you have dental insurance, your plan’s benefits might be based on a utilitarian but less attractive crown. You may have to pay more out of pocket for the crown you and your dentist believe is best for you.
Whatever you choose, though, your modern dental crown will do an admirable, functional job. And it can certainly improve your natural tooth’s appearance.
Starting college is one of life’s biggest transition moments, the first time many young people can truly say they’re on their own. Their freshman year can be both exhilarating and frightening.
The reason for this seeming dichotomy is that both exciting opportunities and harmful pitfalls abound in college life. One such pitfall that’s often overlooked involves dental health: it’s all too easy to neglect good habits and adopt bad ones. But while it may not seem as harmful as other dangers, inattention to your dental health could create consequences that plague you long after graduation.
But being diligent about dental care can help you avoid serious problems now and in the future. At the top of the list: brush and floss your teeth daily and continue seeing a dentist at least twice a year. Hopefully, your parents or guardians have trained you in these vital habits—and they’re definitely habits you should continue for the rest of your life.
Close in importance to good oral hygiene is a healthy diet. Besides eating primarily “natural” food—fresh fruits and vegetables and less-processed foods—you should also set limits on your sugar consumption. This carbohydrate is a primary food for disease-causing bacteria, so limiting as much as possible the sugar you eat to just meal times will lower your risk for tooth decay.
Another area in which you should tread wisely is alcohol consumption. Besides the obvious consequences of alcohol abuse, immoderate drinking can also cause dental problems. Alcohol (and smoking) tends to dry out the mouth, which can increase the levels of oral bacteria and in turn increase your risk of both tooth decay and periodontal (gum) disease.
Finally, avoid getting piercings involving the lips, mouth or tongue even if it’s the thing to do. Piercing hardware can chip teeth and contribute to the shrinking back of the gums (recession). And be sure you practice safe sex: unprotected sexual activity could expose you to viral infections that cause oral problems including cancer.
Your college years should be an exciting and memorable experience. By practicing these and other common sense dental habits, you’ll be sure to remember these years fondly.

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.

Today’s dental care has advanced leaps and bound over the last century. But these advances are tiny steps compared to what many believe may be coming in the next few decades. This optimism arises from our growing understanding of deoxyribonucleic acid (DNA), the chain-like molecule that houses the genetic instructions for the growth, function and reproduction of every cell in the body.
As researchers unlock the secrets of this vast genetic blueprint unique to each individual the possible applications from this knowledge are astounding. Here are just a few possibilities that could one day impact everyone’s oral health.
Preventing tooth decay. This rampant disease, triggered by bacteria (particularly Streptococcus mutans), can cause extensive damage in otherwise healthy teeth. There’s already some indications from the study of genomics that we may be able to stop or at least hinder this disease in its tracks. Already we’re seeing advances in gene therapy that might be able to inhibit the growth of Strep mutans and reduce its colonies in the mouth.
Growing new teeth. Composed of various layers, a natural tooth is part of a dynamic system of bone and gum ligaments that allow movement, protection and nourishment. Although dental implants are the closest and most advanced artificial approximation we now have to them, implants still can’t fully measure up to the function and capabilities of a natural tooth. But further insight into the genetic code may one day allow us to reproduce a living replacement tooth for a lost one.
Harnessing saliva for detecting disease. The impact of genomics related to the mouth could impact more than just the mouth itself. Researchers have discovered that saliva contains genetic information similar to blood, urine and other bodily fluids with markers for various disease conditions. Unlike other fluids, though, saliva is relatively easy to collect. The key is new equipment and testing protocols to take advantage of the information already available in a single drop of saliva.
These examples illustrate the range of possibilities for better health in the future: a reduction in dental disease early in life; new and better ways to restore missing teeth; and quicker ways to diagnose dangerous health conditions.

There’s a lot to like about dental implants for replacing missing teeth. Not only are they life-like, but because they replace the root they also function much like a natural tooth. They also have another unique benefit: a track record for long-lasting durability. It’s estimated more than 95% of implants survive at least ten years, with a potential longevity of more than 40 years.
But even with this impressive record, we should still look at the few that didn’t and determine the reasons why they failed. We’ll soon find that a great number of those reasons will have to do with both oral and general health.
For example, implants rely on adequate bone structure for support. Over time bone cells grow and adhere to the implant’s titanium surface to create the durable hold responsible for their longevity. But if conditions like periodontal (gum) disease have damaged the bone, there might not be enough to support an implant.
We may be able to address this inadequacy at the outset with a bone graft to encourage growth, gaining enough perhaps to eventually support an implant. But if bone loss is too extensive, it may be necessary to opt for a different type of restoration.
Slower healing conditions caused by diseases like diabetes, osteoporosis or compromised immune systems can also impact implant success. If healing is impeded after placement surgery the implant may not integrate well with the bone. An infection that existed before surgery or resulted afterward could also have much the same effect.
Oral diseases, especially gum disease, can contribute to later implant failures. Although the implant’s materials won’t be affected by the infection, the surrounding gum tissues and bone can. An infection can quickly develop into a condition known as peri-implantitis that can weaken these supporting structures and cause the implant to loosen and give way. That’s why prompt treatment of gum disease is vital for an affected implant.
The bottom line: maintaining good oral and general health, or improving it, can help keep your implant out of the failure column. Perform daily brushing and flossing (even after you receive your implant) and see your dentist regularly to help stop dental disease. Don’t delay treatment for gum disease or other dental conditions. And seek medical care to bring any systemic diseases like diabetes under control.
