There are many new and exciting ways now to transform an unattractive smile into one you'll be confident to display. But not all “smile makeover” techniques are new — one in particular has been around for generations: using braces to correct crooked teeth.
Braces have improved the smiles (and also dental health) for millions of people. But as commonplace this orthodontic treatment is, it wouldn't work at all if a natural mechanism for moving teeth didn't already exist. Braces “partner” with this mechanism to move teeth to better positions.
The jawbone doesn't actually hold teeth in place — that's the job of an elastic gum tissue between the teeth and bone called the periodontal ligament. Tiny fibers extending from the ligament attach to the teeth on one side and to the bone on the other. In addition to securing them, the dynamic, moldable nature of the ligament allows teeth to move incrementally in response to forces applied against them.
To us, the teeth feel quite stationary (if they don't, that's a problem!). That's because there's sufficient length of the tooth roots that are surrounded by bone, periodontal ligament and gum tissue. But when pressure is applied against the teeth, the periodontal ligament forms both osteoblasts (bone-forming cells) and osteoclasts (bone-resorbing cells) causing the bone to remodel. This allows the teeth to move to a new position.
Braces take advantage of this in a controlled manner. The orthodontist bonds brackets to the outside face of the teeth through which they pass a thin metal wire. They attach the ends of the wire to the brackets (braces), usually on the back teeth. By using the tension placed in the wire, the orthodontist can control the gradual movement of teeth to achieve proper function and aesthetics. The orthodontist continues to monitor the treatment progress, while making periodic adjustments to the tension.
It takes time, but through this marvelous interplay between nature and dental science you'll gain a more healthy and beautiful smile.

Ever since childhood, when her career as a model and actress took off, Brooke Shields has enjoyed worldwide recognition — through advertisements for designer jeans, appearances on The Muppet Show, and starring roles in big-screen films. But not long ago, that familiar face was spotted in an unusual place: wearing a nasal anesthesia mask at the dentist's office. In fact, Shields posted the photo to her own Instagram account, with the caption “More dental surgery! I grind my teeth!” And judging by the number of comments the post received, she's far from alone.
In fact, researchers estimate that around one in ten adults have dental issues that stem from teeth grinding, which is also called bruxism. (Many children also grind their teeth, but it rarely causes serious problems, and is often outgrown.) About half of the people who are teeth grinders report problems like persistent headaches, jaw tenderness and sore teeth. Bruxism may also result in excessive tooth wear, and may damage dental work like crowns and bridges; in severe cases, loosened or fractured teeth have been reported.
Researchers have been studying teeth grinding for many years; their findings seem to indicate that it has no single cause. However, there are a number of factors that play a significant role in this condition. One is the anatomy of the jaw itself, and the effect of worn or misaligned teeth on the bite. Another factor relates to changes in brain activity that occur during the sleep cycle. In fact, nocturnal (nighttime) bruxism is now classified as a sleep-related movement disorder. Still other factors, such as the use of tobacco, alcohol and drugs, and a high level of stress or anxiety, can make an individual more likely to experience bruxism.
What can be done for people whose teeth grinding is causing problems? Since this condition may have many causes, a number of different treatments are available. Successful management of bruxism often begins by striving to eliminate the factors that may cause problems — for example, making lifestyle changes to improve your health, creating a soothing nighttime environment, and trying stress-reduction techniques; these may include anything from warm baths and soft music at bedtime, to meditation and mindfulness exercises.
Several dental treatments are also available, including a custom-made occlusal guard (night guard) that can keep your teeth from being damaged by grinding. In some cases, a bite adjustment may also be recommended: In this procedure, a small amount of enamel is removed from a tooth to change the way it contacts the opposite tooth, thereby lessening the biting force on it. More invasive techniques (such as surgery) are rarely needed.
A little tooth grinding once in a while can be a normal response to stress; in fact, becoming aware of the condition is often the first step to controlling it. But if you begin to notice issues that could stem from bruxism — or if the loud grinding sounds cause problems for your sleeping partner — it may be time to contact us or schedule an appointment.

Do-it-yourself (DIY) whitening kits are a popular option for restoring a healthy shine to stained and dulled teeth. They're relatively safe and generally live up to their packaging claims.
But a home kit might not always be your best option. Here are 4 reasons why DIY whitening might not be right for you.
You're on the early side of your teen years. Tooth whitening at home is quite popular with teenagers. For older teens it doesn't really pose a dental risk as long as you use the product appropriately (more on that in a moment). However, the immature enamel of younger teens' permanent teeth is still developing and can be vulnerable to damage by whitening processes.
You don't follow instructions well. Not to say you have this particular character quirk — but if you do you may run into trouble with DIY whitening. Home kits are safe if you follow their instructions carefully. If you use them to excess as one 13-year old boy was reported to have done, you could severely (and permanently) erode your teeth's protective enamel.
Your teeth are in need of dental work. Tooth whitening can't fix everything that may be contributing to an unattractive smile. It's always better to have issues like dental disease or chipped teeth addressed first before whitening. And, if your tooth discoloration originates from inside your tooth, a whitening kit won't help — they're only designed for staining on the enamel's outside surface. You'll need a special dental procedure to whiten internal (or intrinsic) tooth staining.
You want to control the amount of brightness. Home kits don't have the level of fine-tuning that a clinical procedure can achieve. While the bleaching agent in a professional whitening solution is much stronger than a home kit, your dentist is trained in techniques that can vary the amount of bleaching, from a softer white to dazzling “Hollywood” bright. And clinical whitening usually takes fewer sessions and may last longer than a home kit.
If you're interested in teeth whitening, see your dentist for a dental examination first before purchasing a DIY kit. Even if you decide to do it yourself, your dentist can give you buying advice for whitening kits, as well as how-to tips.
