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.
September is National Gum Care Month, an ideal time to talk about how to keep your gums healthy. Unfortunately, nearly half of adults have gum disease, which can damage the soft tissue and bone supporting the teeth. In fact, advanced gum disease is the number one reason for tooth loss among adults, and it’s associated with other health problems, including cardiovascular disease, diabetes and pregnancy complications. But there’s good news—gum disease is preventable and, in its early stages, even reversible. Here are some tips for taking care of your gums:
Keep up a good oral hygiene routine
Gum disease begins with plaque buildup, so attack the plaque in your mouth with good dental hygiene. Spend two minutes morning and night brushing all surfaces of your teeth, and floss once a day to get rid of plaque that forms between teeth.
Use a soft toothbrush
The American Dental Association recommends brushing gently with a soft toothbrush. Hard bristles can damage your gums and cause them to pull away from the teeth.
Swish with a mouth rinse
Consider using a mouth rinse. Over-the-counter and prescription oral rinses are available to help wash away food debris, reduce plaque and fight gum inflammation.
Say no to tobacco
Smoking is one of the biggest risk factors for developing gum disease. And it’s not just cigarettes but all forms of tobacco, including e-cigarettes, pipes and chewing tobacco, that raise your risk of gum disease.
Eat a healthy diet
For the best gum health, avoid refined carbohydrates (sugary and starchy foods) and make sure you are getting enough vitamin C, vitamin D and antioxidants (found in berries and green tea, for example). In addition, studies suggest that a diet rich in omega-3 fatty acids may reduce your risk of gum disease and other inflammatory conditions. These healthy fats are found in many fish, nuts, seeds, soy products and vegetable oils.
Come in for regular cleanings
Professional dental cleanings can remove plaque from the tiny spaces that are difficult to reach by simply brushing and flossing. And once plaque hardens to form calculus (tartar), it cannot be removed during your regular oral health care routine at home. Further, at the dental office we can detect gum disease in its early stages—and the earlier gum problems are caught, the more easily they can be reversed.
Everyone has to face the music at some time — even John Lydon, former lead singer of The Sex Pistols, arguably England’s best known punk rock band. The 59-year old musician was once better known by his stage name, Johnny Rotten — a brash reference to the visibly degraded state of his teeth. But in the decades since his band broke up, Lydon’s lifelong deficiency in dental hygiene had begun to cause him serious problems.
In recent years, Lydon has had several dental surgeries — including one to resolve two serious abscesses in his mouth, which left him with stitches in his gums and a temporary speech impediment. Photos show that he also had missing teeth, which, sources say, he opted to replace with dental implants.
For Lydon (and many others in the same situation) that’s likely to be an excellent choice. Dental implants are the gold standard for tooth replacement today, for some very good reasons. The most natural-looking of all tooth replacements, implants also have a higher success rate than any other method: over 95 percent. They can be used to replace one tooth, several teeth, or an entire arch (top or bottom row) of teeth. And with only routine care, they can last for the rest of your life.
Like natural teeth, dental implants get support from the bone in your jaw. The implant itself — a screw-like titanium post — is inserted into the jaw in a minor surgical operation. The lifelike, visible part of the tooth — the crown — is attached to the implant by a sturdy connector called an abutment. In time, the titanium metal of the implant actually becomes fused with the living bone tissue. This not only provides a solid anchorage for the prosthetic, but it also prevents bone loss at the site of the missing tooth — which is something neither bridgework nor dentures can do.
It’s true that implants may have a higher initial cost than other tooth replacement methods; in the long run, however, they may prove more economical. Over time, the cost of repeated dental treatments and periodic replacement of shorter-lived tooth restorations (not to mention lost time and discomfort) can easily exceed the expense of implants.
That’s a lesson John Lydon has learned. “A lot of ill health came from neglecting my teeth,” he told a newspaper reporter. “I felt sick all the time, and I decided to do something about it… I’ve had all kinds of abscesses, jaw surgery. It costs money and is very painful. So Johnny says: ‘Get your brush!’”
We couldn’t agree more. But if brushing isn’t enough, it may be time to consider dental implants.

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.

About one American baby in 700 is born with some form of lip or palate cleft—and the percentage is even higher in other parts of the world. At one time this kind of birth defect sentenced a child to a lifetime of social stigma and related health issues. But thanks to a surgical breakthrough over sixty years ago, cleft defects are now routinely treated and repaired.
Oral and facial clefts happen because a child’s facial structure fails to develop normally during pregnancy. This causes gaps or “clefts” to occur in various parts of the mouth or face like the upper lip, the palate (roof of the mouth), the nose or (more rarely) in the cheek or eye region. Clefts can have no tissue fusion at all (a “complete” cleft) or a limited amount (an “incomplete” cleft), and can affect only one side of the face (“unilateral”) or both (“bilateral”).
There was little that could be done up until the early 1950s. That’s when a U.S. Navy surgeon, Dr. Ralph Millard, stationed in Korea noticed after reviewing a series of cleft photos that tissue needed to repair a cleft was most often already present but distorted by the defect. From that discovery, he developed techniques that have since been refined in the ensuing decades to release the distorted tissue and move it to its proper location.
This revolutionary breakthrough has evolved into a multi-stage approach for cleft repair that often requires a team effort from several dental and medical professionals, including oral surgeons, orthodontists and general dentists. The approach may involve successive surgeries over several years with dental care front and center to minimize the threat of decay, maintain proper occlusion (the interaction between the upper and lower teeth, or “bite”), or restore missing teeth with crowns, bridgework or eventually dental implants.
While it’s quite possible this process can span a person’s entire childhood and adolescence, the end result is well worth it. Because of these important surgical advances, a cleft defect is no longer a life sentence of misery.
