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.

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.

Kill Bill fans have been pressing for a third installment of the stylized revenge tale since Kill Bill, Volume 2 hit the theaters in 2004. Finally, filmmaker Quentin Tarantino is talking about the long-awaited Volume 3 as if it might soon become a reality. The third movie in the franchise would most likely focus on the now-grown daughter of the character played by Vivica A. Fox in the first two. Vivica recently made known that should Kill Bill, Volume 3 go into production, she thinks 24-year-old actress and singer Zendaya would be perfect for the role.
Although Zendaya is a few inches taller than Vivica, the two women have a few things in common. Besides being talented movie and television actresses who have won awards for their roles, they both have camera-ready smiles. And both Vivica and Zendaya can thank their dentists for helping their smiles be their best.
In 2016, Vivica told Dear Doctor magazine that her smile needed a boost, so she opted for dental veneers to correct gaps between her teeth—and she's very happy with them. “I love my veneers!” she exclaimed. Zendaya also had help in achieving her Hollywood-perfect smile. In 2011, early in her career on the Disney channel, she wore clear orthodontic aligners to straighten her teeth. To further perfect her smile, she visited her dentist for professional teeth whitening in 2016, inviting a film crew along to show how easy and effective in-office tooth whitening is.
But you don't have to be a celebrity to enjoy smile-enhancing dental treatments. They are great options for anyone who wants to improve the look of their smile.
Teeth whitening. If your teeth are looking yellowed, in-office whitening can make them up to 10 shades brighter in one visit! Some people prefer professional at-home whitening kits, which produce great results more gradually.
Bonding or veneers. For small chips and cracks, cosmetic bonding can cover flaws by adding layers of a tooth-colored material over the tooth. For bigger flaws, heavy discoloration or gaps between teeth as Vivica had, dental veneers may be the answer. These custom-made thin porcelain shells cover the front-facing surface of the tooth, hiding imperfections to give anyone a Hollywood smile.
Orthodontics. Crooked teeth can detract from the look of a smile. While traditional braces are an option, many people with mild to moderate alignment issues find removable clear aligners the perfect way to get the smile they desire with minimal impact on their daily activities. Clear aligners are very subtle and can be removed for eating and cleaning as well as for special occasions—or for filming scenes, as Zendaya knows.
