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.

Although dental disease prevention has made great strides over the last century, tooth decay and periodontal (gum) disease continue to pose a major health threat. People who’ve lost all of their teeth (edentulism) or most of them suffer the most with adverse effects on their overall health, function and appearance.
Removable dentures have been the traditional and most affordable means to treat edentulism. But even with material and construction advances in recent years, dentures can still lose their fit over time as the bone in the jaw shrinks. This happens because the bone no longer has the stimulus of natural teeth and older cells can’t be replenished at a healthy rate; the continuing compression of traditional dentures on the jaw’s bony ridges compounds the problem.
As the bone shrinks the dentures become loose and uncomfortable to wear. Among other results, this poor fit can drastically affect how you eat: studies of denture wearers have found a decrease in their diet’s nutritional value because they’re eating fewer vegetables or fibrous, “chewy” foods and more foods with refined carbohydrates and fats that are easier to eat but less nutritious.
There is an alternative, though, that might slow bone loss and provide a better long-term fit: an overdenture supported by dental implants. With this appliance, a few implants are strategically installed in the upper or lower jaw. Matched attachments securely fasten the denture to the implants. In this case, the implants not the jaw ridge and gums support the denture thereby preserving the bone.
If you’re healthy enough to undergo a tooth extraction, you should be able to handle implant surgery, a minor procedure usually performed with local anesthesia and with little to no discomfort afterward. It may even be possible to retrofit your current denture to work with the implants, but that will need to be determined during the planning stages.
Although more expensive than a traditional denture, overdentures are much more affordable than fixed restorations stabilized with implants. The difference, though, is the increase in your quality of life — for better nutrition, physical health and social confidence.

There are good reasons, for both health and appearance, to replace a missing tooth with a dental implant or similar restoration as soon as is practical. The bone around a tooth socket diminishes the longer it remains empty, up to 25% the first year. And, of course, your smile is less attractive, especially with a highly visible tooth.
If it’s your teenager, though, you may need to wait on a permanent restoration because their jaws are still developing. An implant placed before completion of jaw development could eventually appear out of alignment with neighboring teeth.
Our biggest concern is protecting bone health at the site of the missing tooth. We can do this and encourage growth by placing bone grafts (processed minerals from another donor) that serve as scaffolds on which surrounding bone can grow. Grafts usually dissolve (resorb) over time, but the rate of resorption can be slowed for a younger patient in need of long-term bone growth.
Planned orthodontic treatment can usually go on as scheduled. The orthodontist may accommodate the tooth loss by adding a temporary tooth within the braces or other device that matches the color and shape of the patient’s natural teeth. The orthodontist will also take care to maintain the empty space for a future implant or other restoration.
A dental implant is considered the best option for a missing tooth, not only for its life-like appearance and durability, but also its ability to encourage bone maintenance. Timing, though, is essential for teenagers. As it grows, the upper jaw will tend to move forward and down. Natural teeth move with this growth; implants, though, are attached differently and won’t move with the jawbone. While the other teeth around them move, the implants can appear to shrink back resulting in an unattractive smile appearance. So waiting until the jaw has finished growing is important.
For most people, jaw growth finishes by age twenty-one for men, women usually faster, but each person is different. The dentist’s expertise and experience, coupled with comparisons of adult family members’ facial appearances, will help determine the right time to undertake a permanent restoration for the best outcome both for health and a permanent, attractive smile.

If you smoke, you know better than anyone how a hard a habit it is to kick. If you want to quit, it helps to have a motivating reason—like lowering your risk for cancer, cardiovascular disease or similar conditions.
Here’s another reason for quitting tobacco: it could be making your teeth and gums less healthy. And, if you’re facing a restoration like dental implants, smoking can make that process harder or even increase the risk of failure.
So, to give your willpower some needed pep talk material, here are 3 reasons why smoking doesn’t mix with dental implants.
Inhaled smoke damages mouth tissues. Though you may not realize it, the smoke from your cigarette or cigar is hot enough to burn the top layer of skin cells in your mouth, which then thickens them. This could affect your salivary glands causing them to produce less saliva, which in turn could set off a chain of events that increases your risk of tooth decay or periodontal (gum) disease. The end result might be bone loss, which could make installing dental implants difficult if not impossible.
Nicotine restricts healthy blood flow. Nicotine, the chemical tobacco users crave, can restrict blood flow in the tiny vessels that course through the mouth membranes and gums. With less blood flow, these tissues may not receive enough antibodies to fight infection and fully facilitate healing, which could interfere with the integration of bone and implants that create their durable hold. Slower healing, as well as the increased chances of infection, could interrupt this integration process.
Smoking contributes to other diseases that impact oral health. Smoking’s direct effect on the mouth isn’t the only impact it could have on your oral health. As is well known, tobacco use can increase the risk of systemic conditions like cardiovascular and lung disease, and cancer. These conditions may also trigger inflammation—and a number of studies are showing this triggered inflammatory response could also affect your body’s ability to fight bacterial infections in the mouth. Less healthy teeth, gums and underlying bone work against your chances of long-term success with implants.

Among dental restorations, implants are the closest prosthetic we have to real teeth. They not only replace the visible crown, but the titanium post imbedded in the jawbone adequately substitutes for the tooth root. Because of their unique design, implants are not only life-like, they’re highly durable and could potentially last for decades.
But while their success rate is remarkably high (more than 95% exceed the ten-year mark), they can fail. Ironically, one possible cause for implant failure is periodontal (gum) disease. Although an implant’s materials are themselves impervious to disease, the tissues and underlying bone that support the implant aren’t. If these natural tissues become infected, the secure hold the implant has can weaken and fail.
A gum infection usually begins with dental plaque, a thin biofilm of bacteria and food particles that builds up on tooth surfaces. Certain strains of bacteria within plaque can infect the gums. One particular form of the disease known as peri-implantitis starts as an initial infection and ensuing inflammation of gum tissues around an implant. The disease can quickly spread down to the bone and destroy the integration between the bone and the implant that helps keep the implant in place.
That’s why it’s important for you to keep the implant and the tissues around it clean of plaque, just as you would the rest of your natural teeth. This requires daily brushing and flossing around the implant and other teeth, and visiting your dentist regularly for more thorough dental cleanings.
You should also be alert to any signs of disease, especially around implants: gum redness, swelling, bleeding or pus formation. Because of the rapidity with which peri-implantitis can spread, you should see your dentist as soon as possible if you notice any of these signs.
Preventing gum disease, and treating it promptly if it occurs, is a key part of implant longevity. Preserving your overall dental health will help make sure your implant doesn’t become a loss statistic.
