While braces are often the stars for straightening smiles, they're not the only cast members in an orthodontic production. Orthodontists occasionally turn to other appliances if the bite problem is challenging. Whatever the tool, though, they usually have something in common—they use the principle of anchorage.
To understand anchorage, let's first consider the classic kid's game Tug of War. With teams on either end of a rope, the object is to pull the opposing team across the center line before they pull you. To maximize your pulling force, the player at the back of your rope, usually your stoutest member, holds steady or "anchors" the rest of the team.
Like a Tug of War team, braces exert force against the teeth. This stimulates the supporting periodontal ligament to remodel itself and allow the teeth to move. The braces use the teeth they are attached to as anchors, which in a lot of cases are the back teeth. By attaching a thin wire to the brackets or braces on the teeth, the orthodontist includes all the teeth on the arch, from one end to the other. Anchored in place, the wire can maintain a constant pressure against the teeth to move them.
But not all bite situations are this straightforward. Sometimes an orthodontist needs to influence jaw growth in addition to teeth movement. For this purpose, they often use orthodontic headgear, which runs around the back of the head or neck and attaches to orthodontic brackets on the teeth. It still involves an anchor but in this case it's the patient's own skull.
In some situations, an orthodontist may feel he or she needs more anchorage as the teeth alone may not be enough. For this, they might establish a separate or additional anchor point using a temporary anchorage device (TAD). A TAD resembles a tiny screw that's inserted into the jawbone near the tooth intended for movement. The orthodontist can then attach the TAD to braces hardware using some form of elastics. After treatment, they remove the TAD.
These are just a couple examples of specialized tools an orthodontist can use for bite correction. Thanks to them and similar devices, even the most complex bite problem can be overcome to create a healthier and more attractive smile.

Dental implants have soared in popularity thanks to their life-likeness, functionality and durability. But these prized qualities have also created an ironic downside—people are much more likely to replace a tooth with an implant rather than go through the time and effort to preserve it.
We say downside because even though an implant is as close to a real tooth as we can now achieve in dentistry, it still can't rival the real thing. It's usually in your long-term health interest to save a tooth if reasonably possible. And, there are effective ways to do so.
Most dental problems arise from two common oral diseases. One is tooth decay, caused by contact with acid produced by bacteria living in dental plaque. We can often minimize the damage by treating the early cavities decay can create. But if we don't treat it in time, the decay can advance into the tooth's pulp chamber, putting the tooth in danger of loss.
We can intervene, though, using root canal therapy, in which we drill into the tooth to access its interior. We clean out the decayed tooth structure, remove the diseased pulp tissue and fill the empty chamber and root canals to seal the tooth and later crown it to further protect it from re-infection.
Periodontal (gum) disease also begins with bacteria, but in this case the infection is in the gum tissues. Over time the ensuing inflammation locks into battle with the plaque-fueled infection. This stalemate ultimately weakens gum attachment, the roots and supporting bone that can also increases risk for tooth loss.
We can stop a gum infection through a variety of techniques, all following a similar principle—completely removing any accumulated plaque and tartar from the teeth and gums. This stops the infection and starts the process of gum and bone healing.
You should be under no illusions that either of these approaches will be easy. Advanced tooth decay can be complex and often require the skills of an endodontist (a specialist in root canals). Likewise, gum disease may require surgical intervention. But even with these difficulties, it's usually worth it to your dental health to consider saving your tooth first before you replace it with an implant.

May is National Save Your Tooth Month, and tooth decay is a leading cause of lost teeth. It all begins with oral bacteria growing rapidly in built-up deposits of dental plaque, and in turn producing high levels of acid. At these levels, acid can erode the minerals in tooth enamel to create holes (“cavities”) that allow bacteria to enter the tooth and infect it.
If at all possible, we need to try to stop tooth decay early by disinfecting and filling these cavities. If not, decay can spread through the teeth to the underlying nerve (pulp) tissue, following passageways known as root canals. If this happens, the chances for saving the tooth are extremely low.
But if the decay does reach the tooth’s innermost layer—the pulp—filling the cavities won’t be enough. Decay this advanced requires a procedure known as root canal therapy, or a root canal for short.
If you winced a little, it’s understandable: Root canals have gained an unfair reputation as an unpleasant experience. In reality, a root canal performed by a skilled dentist or endodontist (a specialist in root canals) isn’t painful. In fact, if you come in with a painful tooth, you’re very likely to leave after the procedure without any pain.
Root canal procedures can vary depending on the type of tooth and the intricacy of its root canal network. Essentially, though, we remove the diseased pulp tissue, and then clean and fill the empty pulp chamber and root canals. This stops the infection and, along with sealing and crowning the tooth, helps prevent a future re-infection.
How do you know if you need a root canal? You may find out from us if we discover advanced decay during a checkup or cleaning appointment. But you may encounter signs yourself like a throbbing toothache, pain during and after eating and drinking, or gum tenderness around a tooth. These are all possible indications of tooth decay.
If you experience any of these signs, you should see us as soon as possible for an examination. And don’t cancel your appointment if the pain goes away—this could simply mean the nerves in the pulp have died and are no longer transmitting pain signals. The infection, though, could still be there and continuing its rampage beyond the tooth and into the surrounding bone tissue.
Root canal therapy may not seem glamorous, but it’s an excellent option for a diseased tooth that would otherwise have to be removed. A root canal could get rid of your pain and give your troubled tooth a new lease on life!

Teenagers and adults alike can improve their smile appearance with dental solutions like teeth whitening or orthodontics. But there are a few cosmetic solutions like porcelain veneers that are better suited for more mature teeth.
Veneers are composed of thin layers of dental porcelain that are bonded to the outside of teeth. They're kind of a tooth "mask" that hides blemishes like chips, discoloration or mild bite problems. They're often less involved and expensive than other types of dental restoration.
Even so, we usually need to remove some of the natural tooth's enamel before applying them. Veneers placed directly on unprepared teeth can appear bulky, so we remove some of the enamel to create a more natural look. And although usually only a slight amount, the alteration is permanent and will require the tooth to have some form of restoration from then on.
This usually doesn't pose a major issue for adults, but it could for a teenager's younger teeth. The nerve-filled dentin in a teenager's still developing tooth is thinner and closer to the pulp (nerve tissue) than in more mature teeth.
There's at least one situation, though, where veneers might be applied safely to a teenager's teeth without this concern. If the teen has abnormally small teeth and are receiving veneers to improve their appearance, they might not need alteration. Because the teeth are already thinner than normal, the "no-prep" veneers may not look bulky when directly bonded to them without preparation.
With most cases, though, it might be best to pursue other options that at the very least can make a cosmetic difference until their teeth are mature enough for veneers. For example, we might be able to repair chipped areas with composite resin material that we form and bond to the tooth to achieve a life-like appearance.
We can discuss these and other options for safely improving your teenager's smile. The important thing is to achieve a more confident appearance without endangering their future health.

Applying braces or clear aligners to move misaligned teeth is only part of an orthodontist's overall mission to eliminate poor bites (malocclusions). Sometimes a malocclusion isn't caused by the teeth at all—the size of the jaw is the problem!
One type in particular, a cross-bite, often happens because the upper jaw has developed too narrowly. As a result, many of the upper teeth fit inside the lower, the opposite of normal. But a tool called a palatal expander can alleviate the problem if it's applied at an early enough age.
The device works because the upper jawbone initially forms as two halves that fit together along a center line in the roof of the mouth (the palate) running from the back of the mouth to the front. These two bone halves remain separate during childhood to facilitate jaw growth, but eventually fuse around puberty.
Consisting of two sets of wire arms joined together by a hinge mechanism in the middle, the expander device is positioned up against the palate. The orthodontist extends each arm to press against the inside of the back teeth, then adds more outward pressure by turning the mechanism in the middle with a small key. During wear, the patient or caregiver will turn the mechanism in the same way to keep up the pressure on the two sides of the jaw.
This continual pressure keeps the two bones moving away from each other and maintaining a center gap between them. In response, more bone forms on the two halves to fill the gap. In time, the newly formed bone should widen the jaw enough to correct any developing malocclusion.
Timing is everything with a palatal expander—if not used before the jaw bones fuse, the patient will need a surgical procedure to separate the bones to pursue treatment. To catch the problem early enough, children should have an orthodontic evaluation on or before they turn six. An orthodontist may be able to identify this or other emerging bite problems and intervene before it becomes worse. Taking this approach can help save you and your child more expensive orthodontic treatment down the road.
