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.
Magician Michael Grandinetti mystifies and astonishes audiences with his sleight of hand and mastery of illusion. But when he initially steps onto the stage, it’s his smile that grabs the attention. “The first thing… that an audience notices is your smile; it’s what really connects you as a person to them,” Michael told an interviewer.
He attributes his audience-pleasing smile to several years of orthodontic treatment as a teenager to straighten misaligned teeth, plus a lifetime of good oral care. “I’m so thankful that I did it,” he said about wearing orthodontic braces. “It was so beneficial. And… looking at the path I’ve chosen, it was life-changing.”
Orthodontics — the dental subspecialty focused on treating malocclusions (literally “bad bites”) — can indeed make life-changing improvements. Properly positioned teeth are integral to the aesthetics of any smile, and a smile that’s pleasing to look at boosts confidence and self-esteem and makes a terrific first impression. Studies have even linked having an attractive smile with greater professional success.
There can also be functional benefits such as improved biting/chewing and speech, and reduced strain on jaw muscles and joints. Additionally, well-aligned teeth are easier to clean and less likely to trap food particles that can lead to decay.
The Science Behind the Magic
There are more options than ever for correcting bites, but all capitalize on the fact that teeth are suspended in individual jawbone sockets by elastic periodontal ligaments that enable them to move. Orthodontic appliances (commonly called braces or clear aligners) place light, controlled forces on teeth in a calculated fashion to move them into their new desired alignment.
The “gold standard” in orthodontic treatment remains the orthodontic band for posterior (back) teeth and the bonded bracket for front teeth. Thin, flexible wires threaded through the brackets create the light forces needed for repositioning. Traditionally the brackets have been made of metal, but for those concerned about the aesthetics, they can also be made out of a clear material. Lingual braces, which are bonded to the back of teeth instead of the front, are another less visible option. The most discrete appliance is the removable clear aligner, which consists of a progression of custom-made clear trays that reposition teeth incrementally.
How’s that for a disappearing act?!

A loose permanent tooth is not a good thing—and not something you should put off having examined. That’s because a loose tooth could soon become a lost tooth.
How we treat it depends on its underlying cause, which could be one of two types. One is primary occlusal trauma, meaning the affected tooth has experienced accidental trauma or higher biting forces than it normally encounters. This usually happens because of teeth grinding habits.
It could also be secondary occlusal trauma. Unlike primary trauma where the supporting gums and bone may be reasonably healthy, secondary trauma occurs because these structures have been severely damaged by periodontal (gum) disease. As the gums begin to detach from a tooth and its underlying bone deteriorates, even normal biting forces can loosen it.
If gum disease is present, our first priority is to bring it under control. We do this primarily by removing all dental plaque (a thin film of bacteria and food particles that triggers the infection and sustains it) and calculus or tartar (calcified plaque). This can take several sessions and, in the case of deep infection, may require a surgical procedure.
On the other hand, if teeth grinding is the primary cause, we’ll focus on minimizing the habit and its effects. One way is to create a custom-fitted guard worn to prevent upper and lower teeth from making solid contact. You may also need to improve your management of stress—another factor in teeth grinding—through medication, therapy or biofeedback.
In either case, improved periodontal health will help the gums naturally regain their strong attachment with help, if necessary, from gum tissue or bone grafting surgery. But this healing process can take time, so we may need to secure a loose tooth in the interim by splinting it to neighboring stable teeth. This usually requires bonding rigid material or metal across the back of all involved teeth or in a channel cut along the teeth’s biting surfaces. In this way the more stable teeth support the loose one.
Splinting may be temporary as the mouth heals from disease or trauma and the teeth regain their stability. In some cases, though, it may be permanent. Either way, dealing promptly with a loose tooth can help ensure it’ll survive—so see your dentist as soon as possible.

If you're ready to put the "pizzazz" back into your smile, your dentist may be able to help. It's possible your dull, dingy smile could be transformed with teeth whitening.
Teeth whitening or bleaching is a technique that applies a solution with a bleaching agent (usually up to 35% hydrogen peroxide in an office setting) to the teeth to whiten them. Although there are Do-It-Yourself home whitening kits you can use, there are a few good reasons why you should first consider a whitening procedure in a dental office setting.
To begin with, you should first have your teeth examined by a dentist to determine why they're discolored. Certain foods and beverages we consume or tobacco habits are the usual culprits causing stains on the enamel, the outermost tooth layer. These are the kinds of stains targeted by most whitening solutions.
But the interior of a tooth can also become discolored for reasons like trauma, past dental work or tetracycline use at an early age. If your staining is internal (intrinsic) rather than external (extrinsic) reducing that discoloration will require an invasive procedure only a dentist can perform—a home kit won't be able to do the job.
Another reason for having your teeth whitened by your dentist (even extrinsic staining) involves your time and the degree of brightness you'd like. Because dentists use stronger bleaching solutions (home kits usually use a weaker solution of 10% carbamide peroxide) it takes fewer sessions than home kits to achieve results—and they may last longer. In addition, dentists have more control over the level of brightness to match your expectations of a more subdued, natural look or a dazzling "Hollywood" smile.
A dentist can also help you navigate special circumstances like matching and managing natural teeth whiteness with dental restorations (which don't bleach) or special whitening situations like a single discolored tooth.
Even if you eventually decide to go the home kit route, consulting with a dentist first can still prove helpful. You'll get expert advice on products, tips on how to apply them and how to prolong the whitening effect. Whichever way you go, home kit or dentist, you can gain a brighter, more confident smile with teeth whitening.

Unlike the months on either side, August isn't known for major holidays. But it does have one cause for celebration: National Fresh Breath Day! True, this observance will probably never achieve big-time recognition. Yet everyone would agree that fresh breath is something to appreciate! Unfortunately, bad breath is a persistent problem for many people. The first step in treating it is to identify the cause. Here are 5 common causes of bad breath:
1. Poor oral hygiene. Certain types of oral bacteria cause bad breath, and the mouth provides a perfect environment for them—especially when dental plaque and food debris is not well cleansed. So to keep your breath fresh, maintain a diligent oral hygiene routine. This includes brushing your teeth twice a day with fluoride toothpaste and flossing at least once a day. For an extra-clean mouth, use a tongue scraper—a plastic tool about the size of a toothbrush that's available in most drug stores. This will remove bacteria and food debris from your tongue for extra freshness.
2. Oral diseases. Bad odors in your mouth may also be caused by infections—which is what tooth decay and gum disease actually are. Sometimes old fillings wear out, allowing bacteria to re-infect a tooth that was once treated for decay. Other signs of these common oral diseases include tooth pain and bleeding or puffy gums. If you notice any of these, don't ignore it—make a dental appointment today!
3. Diet. Smelly foods will give you smelly breath; it's that simple. And the odors may linger after you have eaten them. When onion, garlic and other pungent foods are digested, their odor-producing substances enter your bloodstream and proceed to your lungs—which can affect how your breath smells. If you suspect your dietary habits are causing bad breath, try eliminating certain foods (at least temporarily) and see if that helps.
4. Dry mouth. Saliva helps cleanse your mouth, so reduced saliva flow can lead to bad breath. This accounts for "morning breath," which is caused when the mouth dries out during sleep (especially if you are a mouth-breather). However, some people don't produce enough saliva throughout the day. Sometimes it's just that they don't drink enough water. But a very common cause of chronic dry mouth is regular use of medications, both prescription and over-the-counter. If you notice that medication is drying out your mouth, let your doctor know. And stay hydrated!
5. Smoking. Given that smoking increases your risk for many serious diseases, including oral cancer, the fact that it can lead to bad breath seems almost trivial. Still, it's worth noting that smoking causes mouth odor both directly and indirectly by reducing the flow of saliva and promoting gum disease. In fact, tobacco in all forms is a hazard to your health.
