All crowns are designed to restore functionality to a damaged tooth. But crowns can differ from one another in their appearance, in the material they’re made from, and how they blend with other teeth.
A crown is a metal or porcelain artifice that’s bonded permanently over a decayed or damaged tooth. Every crown process begins with preparation of the tooth so the crown will fit over it. Afterward, we make an impression of the prepared tooth digitally or with an elastic material that most often is sent to a dental laboratory to create the new crown.
It’s at this point where crown composition and design can diverge. Most of the first known crowns were made of metal (usually gold or silver), which is still a component in some crowns today. A few decades ago dental porcelain, a form of ceramic that could provide a tooth-like appearance, began to emerge as a crown material. The first types of porcelain could match a real tooth’s color or texture, but were brittle and didn’t hold up well to biting forces. Dentists developed a crown with a metal interior for strength and a fused outside layer of porcelain for appearance.
This hybrid became the crown design of choice up until the last decade. It is being overtaken, though, by all-ceramic crowns made with new forms of more durable porcelain, some strengthened with a material known as Lucite. Today, only about 40% of crowns installed annually are the metal-porcelain hybrid, while all-porcelain crowns are growing in popularity.
Of course, these newer porcelain crowns and the attention to the artistic detail they require are often more expensive than more traditional crowns. If you depend on dental insurance to help with your dental care costs, you may find your policy maximum benefit for these newer type crowns won’t cover the costs.
If you want the most affordable price and are satisfied primarily with restored function, a basic crown is still a viable choice. If, however, you would like a crown that does the most for your smile, you may want to consider one with newer, stronger porcelain and made with greater artistic detail by the dental technician. In either case, the crown you receive will restore lost function and provide some degree of improvement to the appearance of a damaged tooth.
Periodontal (gum) disease is a serious infection that can damage more than periodontal tissues — supporting bone structure is also at risk. Any bone loss could eventually lead to tooth loss.
To stop it from causing this kind of damage, we must match this disease's aggressiveness with equally aggressive treatment. The various treatment techniques all have the same goal: to remove bacterial plaque, the source of the infection, from all oral surfaces, including below the gum line. Buildup of plaque, a thin film of food particles, after only a few days without adequate brushing and flossing is enough time to trigger gum disease.
The basic removal technique is called scaling, using hand instruments called scalers to manually remove plaque and calculus (hardened plaque deposits) above or just below the gum line. If the disease or infection has advanced to the roots, we may use another technique called root planing in which we shave or “plane” plaque and tartar from the root surfaces.
Advancing gum disease also causes a number of complex problems like abscesses (localized infections in certain areas of gum tissue) or periodontal pockets. In the latter circumstance the slight normal gap between tooth and gums becomes deeper as the tissues weaken and pull away. This forms a void or pocket that fills with inflammation or infection that must be removed. Plaque buildup can also occur around furcations, the places where a tooth's roots divide off from one another.
It may be necessary in these more complex situations to perform a procedure known as flap surgery to gain access to these infected areas. As the name implies, we create an opening in the gums with a hinge, much like the flap of a paper envelope. Once the accessed area has been cleansed of plaque and infected tissues (and often treated with antibiotics to stop further infection), the flapped tissue is closed back in place and sutured.
To avoid these advanced stages it's important for you to see us at the first sign of problems: swollen, red or bleeding gums. Even more important is to reduce your risk for gum disease in the first place with dedicated daily brushing and flossing to remove plaque and regular dental visits for more thorough cleaning.
Gum disease can be devastating to your long-term dental health. But with diligent hygiene and early aggressive treatment you can stop this destructive disease in its tracks.

One of the best ways to cover up teeth that have undergone restorative procedures is using crowns. You dentist in Arlington, VA, Dr. Bruce Hanley, is more than happy to tell you more about crowns and their benefits.
What are dental crowns:
Crowns look like caps and are made of porcelain. Your Arlington dentist takes an impression of your teeth and sends them to a lab where custom crowns are made just for you. In the meantime though, you're given a temporary crown.
So why get a dental crown anyway?
During restorative procedures, such as root canals, a significant amount of natural tooth is removed. This leaves the tooth exposed to decay and susceptible to breakage, which is why a dental crown is placed over the tooth. The dental crown reinforces the tooth and allows it to withstand various degrees of pressure, meaning you can enjoy eating without the worry of ruining your tooth.
Here are some other procedures that use dental crowns:
- Attaching bridges
- Covering dental implants
- Covering an existing filling that may be dislocated
- Covering stained or discolored teeth
How do I take care of my crowns?
- It goes without saying that you need to brush twice a day and floss before bed. However, make sure to give special attention to the area around your dental crown. It's important to avoid plaque to reduce the chances of cavities forming and impacting the dental restoration.
- In addition to brushing and flossing, your diet can contribute to your crowns lasting up to 8 years, or more. Don't bite into ice and avoid sugary foods like soda and candy. Sugars contain the bacteria that produce plaque. So try eating healthy foods like apples and carrots that scrape the plaque off your teeth and incorporate more water into your diet.
- Bruxism, when someone grinds their teeth, can reduce how long your crowns last as well. So make sure you find a solution for it with your dentist, like getting a mouth guard or splints.
For more information on dental crowns and what they can do for you, contact Dr. Hanley in Arlington, VA, as soon as possible.
A recent episode of “America’s Got Talent” featured an engaging 93-year-old strongman called The Mighty Atom Jr. The mature muscleman’s stunt: moving a full-sized car (laden with his octogenarian “kid brother,” his brother’s wife, plus Atom’s “lady friend”) using just his teeth. Grinning for host Howie Mandel, Atom proudly told the TV audience that his teeth were all his own; then he grasped a leather strap in his mouth, and successfully pulled the car from a standstill.
We’re pleased to see that the Atom has kept his natural teeth in good shape: He must have found time for brushing and flossing in between stunts. Needless to say, his “talent” isn’t one we’d recommend trying at home. But aside from pulling vehicles, teeth can also be chipped or fractured by more mundane (yet still risky) activities — playing sports, nibbling on pencils, or biting too hard on ice. What can you do if that happens to your teeth?
Fortunately, we have a number of ways to repair cracked or chipped teeth. One of the easiest and fastest is cosmetic bonding with tooth-colored resins. Bonding can be used to fill in small chips, cracks and discolorations in the teeth. The bonding material is a high-tech mixture of plastic and glass components that’s extremely lifelike, and can last for several years. Plus, it’s a procedure that can be done right in the office, with minimal preparation or discomfort. However, it may not be suitable for larger chips, and it isn’t the longest-lasting type of restoration.
When more of the tooth structure is missing, a crown (or cap) might be needed to restore the tooth’s appearance and function. This involves creating a replacement for the entire visible part of the tooth in a dental lab — or in some cases, right in the office. It typically involves making a model of the damaged tooth and its neighbors, then fabricating a replica, which will fit perfectly into the bite. Finally, the replacement crown is permanently cemented to the damaged tooth. A crown replacement can last for many years if the tooth’s roots are in good shape. But what if the roots have been dislodged?
In some cases it’s possible to re-implant a tooth that has been knocked out — especially if it has been carefully preserved, and receives immediate professional attention. But if a tooth can’t be saved (due to a deeply fractured root, for example) a dental implant offers today’s best option for tooth replacement. This procedure has a success rate of over 95 percent, and gives you a natural looking replacement tooth that can last for the rest of your life.
So what have we learned? If you take care of your teeth, like strongman Atom, they can last a long time — but if you need to move your car, go get the keys.

Twice a year dental cleanings are an important aspect of optimal oral health. But if you’re not brushing and flossing every day, your dental visits could change from regular maintenance to teeth rescue missions.
These two hygiene tasks don’t take long—a single trip with floss around each tooth and a couple of minutes of brushing at least twice a day—but you’ll need to perform them effectively to get the most out of them. Not to worry, though: with a little practice and helpful advice from us, this small investment in time and effort could save your teeth—and your money.
The first thing to know, though, is the reason behind brushing and flossing: to remove disease-causing bacterial plaque that can build up daily on teeth. Bacteria produce acid, which at elevated levels can erode enamel and lead to decay; and some bacterial strains can cause periodontal (gum) disease. These infections could ultimately lead to gum recession, bone deterioration and tooth loss.
Daily brushing and flossing lowers your risk of this occurring. It’s your preference in what order you do them, but for now let’s start with flossing.
There are a number of techniques—and tools—for effective flossing. If you’re using thread floss, simply cut off about 18 inches and wrap each end around the middle finger from each hand. Use the remaining fingers to create a small amount of floss between the two best fingers for a particular area of the mouth and gently pull the floss in between the tooth gap. Form a “C” shape around one of the tooth sides and rub up and down until you hear a squeak (which you’ll only hear if you use un-waxed floss). Now, repeat the action with the adjacent tooth, then move to the next and each succeeding gap and do the same until you’ve cleaned each side of each tooth.
When brushing, hold your toothbrush gently like a paintbrush or pencil at about a 45-degree angle with just a small amount of toothpaste on the end bristles. All it takes is a gentle scrubbing or wiggling motion and the abrasives and detergents in the toothpaste will do the rest. Just make sure you fully brush all your teeth and gum surfaces, which should take about two minutes.
Along with regular dental visits and a low-sugar diet to discourage bacterial growth, brushing and flossing will help you avoid disease and enjoy the best oral health possible.
