Your teen is about to embark on an orthodontic journey to a straighter, more attractive smile. But although you're excited about the outcome, you both may be steeling yourselves for a few years of "life with braces."
But maybe not—your teen may be able to take advantage of a different kind of corrective appliance: clear aligners. This 21st Century teeth movement method has a number of advantages over braces. For teens, though, there's one big one that could have a huge impact on their social life—clear aligners are nearly invisible to other people.
Clear aligners consist of a series of clear, removable, computer-generated trays based on photographs, models and x-rays of an individual patient's teeth and bite. Each of the trays is slightly different from the previous one in the series, and by wearing each one for about two weeks before moving on to the next, the aligners gradually move the teeth to the desired new positions.
Besides reducing embarrassment often associated with wearing metal braces, clear aligners have other benefits. Unlike braces, they can be removed for eating, easier oral hygiene or for rare special occasions (although for best effectiveness, they should be worn for 20 to 22 hours each day). Recent developments like added elements that help target certain teeth for movement or "power ridges" for more controlled and efficient force have increased the range of bite problems they can be used to correct.
While this means clear aligners can be used for many bite problems, in some severe cases braces and other orthodontic treatments might still be necessary. And because they're not fixed like braces (only the orthodontist can remove them) the patient must have the maturity and self-discipline to wear them consistently.
Your teen will need to undergo a thorough orthodontic examination to see if clear aligners are a viable option for them. If so, it could make the next few treatment years less stressful for both of you.

For over a hundred years dental amalgam — a combination of silver, mercury, tin and other metals — has been an effective filling material for teeth damaged by decay. But it has one major drawback — its metallic appearance stands out in stark contrast to the natural color of teeth.
As an alternative, composite resin fillings can match the color, shape and texture of natural teeth. These materials and the techniques used to bond them are proving just as effective as and more aesthetically pleasing than dental amalgam.
Fillings help protect and preserve a decayed tooth. By first removing decayed tooth structure through drilling, the resulting void is filled with durable material that strengthens the tooth and provides it protection from further decay.
The ultimate goal for restoration is to return the tooth to as near normal form and function as possible. Dental amalgam serves well in terms of function, providing the tooth strength in the face of the daily biting forces it encounters. In contrast, composite resins excel in appearance, but haven’t always matched the durability of amalgam. They’re material construction has improved over time, though, as well as the techniques used to bond them to teeth.
Most of these bonding techniques incorporate layering. The first step is to seal the dentin (the porous, living tissue just below the enamel); we then build up the composite material layer by layer within the tooth using special bonding adhesive and curing lights. In some cases where a large volume of tooth structure must be replaced, the restoration is first formed on the tooth and then removed for curing before being cemented into the tooth or a separate restoration is formed by a dental lab.
The end result is a tooth which both looks and functions like a fully intact tooth. Though care must be taken not to subject composite resin restorations to undue forces (no cracking open nutshells, for example), your new filling should continue to serve you and look great for a long time to come.

At any given time some 4 million teens and pre-teens are wearing braces or other orthodontic appliances to correct a malocclusion (poor bite). While most cases are straightforward, some have difficulties that increase treatment time and cost.
But what if you could reduce some of these difficulties before they fully develop? We often can through interceptive orthodontics.
This growing concept involves early orthodontic treatment around 6 to 10 years of age with the goal of guiding the development of a child’s jaws and other mouth structures in the right direction. These early years are often the only time of life when many of these treatments will work.
For example, widening the roof of the mouth (the palate) in an abnormally narrow upper jaw takes advantage of a gap in the bone in the center of the palate that doesn’t fuse until later in adolescence. A device called a palatal expander exerts outward pressure on the back teeth to influence the jawbone to grow out. New bone fills in the gap to permanently expand the jaw.
In cases with a developing overbite (the upper front teeth extending too far over the lower teeth when closed), we can install a hinged device called a Herbst appliance to the jaws in the back of the mouth. The hinge mechanism coaxes the lower jaw to develop further forward, which may help avoid more extensive and expensive jaw surgery later.
Interceptive treatments can also be fairly simple in design like a space retainer, but still have a tremendous impact on bite development. A space maintainer is often used when a primary (“baby”) tooth is lost prematurely, which allows other teeth to drift into the empty space and crowd out the incoming permanent tooth. The wire loop device is placed within the open space to prevent drift and preserve the space for the permanent tooth.
To take advantage of these treatments, it’s best to have your child’s bite evaluated early. Professional organizations like the American Association of Orthodontists (AAO) recommend a screening by age 7. While it may reveal no abnormalities at all, it could also provide the first signs of an emerging problem. With interceptive orthodontics we may be able to correct them now or make them less of a problem for the future.

During his former career as a professional footballer (that's a soccer star to U.S. sports fans) David Beckham was known for his skill at “bending” a soccer ball. His ability to make the ball curve in mid-flight — to avoid a defender or score a goal — led scores of kids to try to “bend it like Beckham.” But just recently, while enjoying a vacation in Canada with his family, “Becks” tried snowboarding for the first time — and in the process, broke one of his front teeth.
Some fans worried that the missing tooth could be a “red card” for Beckham's current modeling career… but fortunately, he headed straight to the dental office as soon as he arrived back in England. Exactly what kind of treatment is needed for a broken tooth? It all depends where the break is and how badly the tooth is damaged.
For a minor crack or chip, cosmetic bonding may offer a quick and effective solution. In this procedure, a composite resin, in a color custom-made to match the tooth, is applied in liquid form and cured (hardened) with a special light. Several layers of bonding material can be applied to re-construct a larger area of missing tooth, and chips that have been saved can sometimes be reattached as well.
When more tooth structure is missing, dental veneers may be the preferred restorative option. Veneers are wafer-thin shells that are bonded to the front surface of the teeth. They can not only correct small chips or cracks, but can also improve the color, spacing, and shape of your teeth.
But if the damage exposes the soft inner pulp of the tooth, root canal treatment will be needed to save the tooth. In this procedure, the inflamed or infected pulp tissue is removed and the tooth sealed against re-infection; if a root canal is not done when needed, the tooth will have an increased risk for extraction in the future. Following a root canal, a tooth is often restored with a crown (cap), which can look good and function well for many years.
Sometimes, a tooth may be knocked completely out of its socket; or, a severely damaged tooth may need to be extracted (removed). In either situation, the best option for restoration is a dental implant. Here, a tiny screw-like device made of titanium metal is inserted into the jaw bone in a minor surgical procedure. Over time, it fuses with the living bone to form a solid anchorage. A lifelike crown is attached, which provides aesthetic appeal and full function for the replacement tooth.
So how's Beckham holding up? According to sources, “David is a trooper and didn't make a fuss. He took it all in his stride." Maybe next time he hits the slopes, he'll heed the advice of dental experts and wear a custom-made mouthguard…

Your tooth is in peril if its innermost layer, the pulp, becomes infected and inflamed. Deep tooth decay, repeated dental procedures or fractures can all expose the pulp and ultimately the roots to infection and lead to tooth loss.
But that scenario isn't inevitable — we can often save the tooth with a root canal treatment. By accessing the tooth's interior through a prepared hole, we're able to clean out the infected tissue in the pulp chamber and root canals, and fill the empty space with a special filling. We then cap the tooth with a custom crown to protect it from a re-infection.
Root canal treatments have a very high success rate — chances are good your tooth will survive for many years afterward. But there's a slight chance the tooth may become re-infected; in that case, a second root canal treatment may be in order.
In a few cases, though, a second root canal may not be advisable, and could even accelerate damage to the tooth. For example, if past dental work resulted in an extensive crown restoration, accessing the root canals the conventional way will require disassembling that restoration. This could weaken the tooth significantly.
We can approach the problem from a different route: instead of accessing the tooth's interior through the crown (the visible part of the tooth), we instead perform a surgical procedure called an apicoectomy, which accesses the tooth at the root end through the gums.
In this procedure we numb the area with local anesthesia and then make a small incision through the gums at the level of the affected root. After access, we remove any diseased tissue around the root and a few millimeters of the root tip itself. We then insert a small filling in its place to seal the canal and prevent further infection. In some cases we may also insert a graft to encourage bone growth and aid in healing.
Over time, the affected area will heal and return to normal function. Even if a traditional root canal treatment can't be used, an apicoectomy could be another option for saving your tooth.
