What a difference forty years can make: Dental bridges once occupied the top spot for choices to replace missing teeth until the arrival of dental implants in the 1980s. Today, dental implants are the gold standard for dental restoration.
But although bridgework may have lost “first chair” in the orchestra of restorations, it's still a viable option. In fact, it can be the best option in certain situations.
Bridges consist of a series of porcelain crowns fused together like fence pickets. The center crowns, known as the pontics, “bridge” the gap left by a missing tooth or teeth. The crowns on each end, the abutment teeth, crown the natural teeth on either side of the gap to support the bridge.
Bridges are effective and durable, but with a major downside: To accommodate the abutment crowns, we must reduce the size of the natural teeth to which they'll be attached. This alteration can weaken those teeth's structure and require them from then on to have some form of restoration. They're also at higher risk for tooth decay.
Implants, on the other hand, don't require this alteration, and may also be more durable than bridges. Why then consider a bridge?
Price can be a factor: Implants may be more expensive, especially involving multiple teeth. Keep in mind, though, that this only compares the initial cost: Because implants have a 95% or more ten-year success rate, with further evidence they could potentially last for decades, they may actually cost less in the long-run than bridge restorations that have a higher chance of being replaced sooner.
But the prime reason is that some dental situations aren't suitable for dental implants. For instance, implants require a certain amount of bone for proper placement, so people with extensive bone loss may not be able to acquire them. Health conditions like uncontrolled diabetes or a compromised immune system can also complicate implant installation. A bridge in these cases may represent a better alternative.
With the help of your dentist, you'll need to consider your individual situation, dental and financial, in deciding between an implant or a bridge. And, if a dental bridge is your best option, it will be a solid choice for restoring your missing teeth and your smile.

According to Forbes Magazine, Kylie Jenner is the world's youngest billionaire at age 22. Daughter of Caitlyn (Bruce) Jenner and Kris Jenner, Kylie is the founder and owner of the highly successful Kylie Cosmetics, and a rising celebrity in her own right. But even this busy CEO couldn't avoid an experience many young people her age go through each year: having her wisdom teeth removed.
At around 10 million removals each year, wisdom teeth extraction is the most common surgical procedure performed by oral surgeons. Also called the third molars, the wisdom teeth are in the back corners of the jaws, top and bottom. Most people have four of them, but some have more, some have fewer, and some never have any. They're typically the last permanent teeth to come in, usually between ages 17 and 25.
And therein lies the problem with wisdom teeth: Many times, they're coming in late on a jaw already crowded with teeth. Their eruption can cause these other teeth to move out of normal alignment, or the wisdom teeth themselves may not fully erupt and remain fully or partially within the gums (a condition called impaction). All of this can have a ripple effect, decreasing dental function and increasing disease risk.
As Kylie Jenner has just experienced, they're often removed when problems with bite or instances of diseases like tooth decay or gum disease begin to show. But not just when problems show: It's also been a common practice to remove them earlier in a kind of “preemptive strike” against dental dysfunction. But this practice of early wisdom teeth extraction has its critics. The main contention is that early extractions aren't really necessary from a medical or dental standpoint, and so patients are unduly exposed to surgical risks. Although negative outcomes are very rare, any surgical procedure carries some risk.
Over the last few years, a kind of middle ground consensus has developed among dentists on how to deal with wisdom teeth in younger patients. What has emerged is a “watch and wait” approach: Don't advise extraction unless there is clear evidence of developing problems. Instead, continue to monitor a young patient's dental development to see that it's progressing normally.
Taking this approach can lead to fewer early wisdom teeth extractions, which are postponed to a later time or even indefinitely. The key is to always do what's best for a patient's current development and future dental health.
Still, removing wisdom teeth remains a sound practice when necessary. Whether for a high school or college student or the CEO of a large company, wisdom teeth extraction can boost overall dental health and development.

Most dental problems are caused by tooth decay or periodontal (gum) disease, easily preventable with dedicated daily hygiene and regular dental care. But there are a few other rare conditions to be on alert for that could pose just as serious a threat to your dental health.
One of these is a phenomenon called root resorption. Put simply, certain cells arise within a tooth root that eat away and dissolve (resorb) tooth structure. Left unchecked, it could eventually lead to the tooth's demise.
Although its exact cause remains elusive, we suspect root resorption is associated with trauma to the gum ligaments earlier in life, perhaps from an injury or too much force applied during orthodontics. Other possible contributing factors include teeth-grinding habits or internal tooth bleaching procedures.
Root resorption in adults isn't that common, so your chances of experiencing it are low. But it is still possible, so you should be on the lookout for potential signs: Early on, it may appear as faint pink spots on teeth where the enamel has filled with the destructive cells eating away at the tooth. In time, these spots can increase to form cavities.
More than likely, though, your dentist may detect the problem during a dental exam. That's why regular dental cleanings and checkups are essential—a routine exam is a prime opportunity to uncover conditions like root resorption that silently undermine your teeth.
If found early, we can often treat root resorption effectively. We can often expose a small affected area with minor gum surgery, remove the harmful cells and fill any cavities with a tooth-colored filling. In some cases, we may recommend orthodontics beforehand to encourage a buildup of bone around the root by moving the affected tooth outward from the jawbone. If the resorption has affected the tooth pulp, you may also need a root canal treatment.
There is also the possibility with advanced resorption that the best course of action is to remove the tooth and replace it with a dental implant. So, keep up your regular dental visits—early detection and intervention can stop this destructive dental condition from destroying your tooth.

Each year, millions of children and teenagers wear braces or clear aligners to straighten a crooked smile. But there may be a way to treat some of these bite problems and avoid braces—by intercepting the problem at an earlier age.
This can often be done if the bite problem stems from abnormal jaw development rather than misaligned teeth. An example of this occurs when the upper jaw growth outpaces the lower jaw, causing the upper teeth to protrude beyond the lower teeth. Aside from the effect on appearance, protruding front upper teeth may extend beyond the protection of the lip and be more prone to injury.
A device called a Herbst appliance could prevent this from happening. The top of the device has two hinged metal tubes that connect to elastic bands bonded to the back teeth on both sides of the upper jaw. The bottom also has tubes affixed in the same way to the bottom teeth, except they're slightly smaller and fit within the upper tubes.
The lower tubes sliding within the upper tubes produces slight pressure against the lower jaw to ease it forward. This gradually influences the lower jaw to grow at a pace equal with the upper jaw to decrease the chances of poor bite development. Unlike other corrective methods, the Herbst appliance fixed in place and out of the way won't interfere with sports or other physical activities.
An installed Herbst appliance may change a patient's sensations during swallowing, eating or speaking, but most children adapt to the changes within a few days. And, because the device can create challenges for keeping the back teeth clean, many dentists recommend adding a fluoride rinse to daily brushing and flossing as an added boost against tooth decay.
The Herbst appliance is most effective during the period of most rapid physical growth between the ages of 11 and 14, but if the teeth are already beginning to protrude it can be undertaken as early as 8 or 9. Either way, this important orthodontic tool could help address a complicated bite problem and reduce the need for more costly orthodontic treatment later on.

You can't correct a poor bite with braces or clear aligners overnight: Even the most cut-and-dried case can still require a few years to move teeth where they should be. It's a welcome relief, then, when you're finally done with braces or aligner trays.
That doesn't mean, however, that you're finished with orthodontic treatment. You now move into the next phase—protecting your new smile that took so much to gain. At least for a couple of more years you'll need to regularly wear an orthodontic retainer.
The name of this custom-made device explains its purpose: to keep or “retain” your teeth in their new, modified positions. This is necessary because the same mechanism that allows us to move teeth in the first place can work in reverse.
That mechanism centers around a tough but elastic tissue called the periodontal ligament. Although it primarily holds teeth in place, the ligament also allows for tiny, gradual tooth movement in response to mouth changes. Braces or aligner trays take advantage of this ability by exerting pressure on the teeth in the direction of intended movement. The periodontal ligament and nature do the rest.
But once we relieve the pressure when we remove the braces or aligners, a kind of “muscle memory” in the ligament can come into play, causing the teeth to move back to where they originally were. If we don't inhibit this reaction, all the time and effort put into orthodontic treatment can be lost.
Retainers, either the removable type or one fixed in place behind the teeth, gently “push” or “pull” against the teeth (depending on which type) just enough to halt any reversing movement. Initially, a patient will need to wear their retainer around the clock. After a while, wear time can be reduced to just a few hours a day, usually during sleep-time.
Most younger patients will only need to wear a retainer for a few years. Adults who undergo teeth-straightening later in life, however, may need to wear a retainer indefinitely. Even so, a few hours of wear every day is a small price to pay to protect your beautiful straightened smile.
