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.

Orthodontic treatment is a big investment. But given the benefits for future good health and a more attractive smile, it's well worth it.
In the here and now, though, braces wearers face a different threat to their dental well-being — dental disease. Wearing braces can actually increase the risk of disease and make it more difficult to fight.
Tooth decay and periodontal (gum) disease, the two most common forms of dental disease, usually arise from plaque, a thin film of bacteria and food particles on tooth surfaces. The bacteria produce acid, which erodes enamel and makes the teeth susceptible to decay. Certain bacteria can also infect the gums and eventually weaken their attachment to teeth. Thorough brushing and flossing everyday removes this disease-triggering plaque buildup.
But braces' hardware can make brushing and flossing more difficult. The brackets attached to the teeth and wires laced through them make it more difficult for floss and brush bristles to access all the areas around the teeth. Plaque can build up in certain spots; it's estimated braces wearers have two to three times the plaque of a person not wearing braces. Acid can also remain in contact with some of the enamel surface for too long.
It's important, therefore, if you wear braces to make a concerted effort to brush and floss thoroughly. Besides improving technique and taking more time, you might also consider additional aids. You can obtain toothbrushes specially designed for use with braces, as well as floss holders or threaders that make it easier to access between teeth. Another flossing alternative is an oral irrigator that sprays water under pressure between teeth is an alternative to flossing.
As a precaution against acid damage, we can boost enamel protection with additional fluoride applied to your teeth. We may also prescribe antibacterial rinses to keep the bacteria population low.
Above all, be sure to look out for signs of disease like swollen or bleeding gums or pain. As soon as you sense something out of the ordinary, be sure and contact us.

Wearing braces will probably never make your list of Most Pleasurable Life Experiences: you'll have to avoid certain foods and habits, endure some occasional discomfort, and perhaps feel some embarrassment about your appearance. The good news, though, is that at worst, these are mostly no more than inconveniences and additionally they're well worth the straighter, more attractive smile you'll achieve.
But there's one downside to braces that can lead to something more serious. The braces hardware makes brushing and flossing more difficult—and that could increase your risk of dental disease.
The principal goal of oral hygiene is to remove dental plaque, a thin film of accumulated bacteria and food particles that can cause tooth decay or periodontal (gum) disease. Without effective brushing and flossing, plaque can build up quickly and make the chances of having either of these two diseases more likely.
Not only does the braces hardware hinder your toothbrush's or floss's access to the parts of the teeth it covers, but it can also create "hiding places" for plaque build-up. Several studies have found that braces wearers on average have up to two to three times the plaque build-up of non-braces wearers.
There are ways, though, to make hygiene easier while wearing braces, particularly with flossing. Floss threaders or interproximal brushes can both be used to access between teeth while wearing braces. Another option is a water flosser or irrigator that sprays pressurized water between teeth (and beneath brackets and wires) to remove plaque. And braces wearers can get a prevention boost with topical fluoride applications or antibacterial mouth rinses to reduce disease-causing bacteria.
Besides taking a little extra time with brushing and flossing, you can also boost your mouth's health with good nutrition choices, less sugar consumption and keeping up regular dental visits. And, you should also see your dentist promptly if you notice any signs of tooth or gum problems—the sooner you have it checked and treated, the less damage any dental disease is likely to cause.
It's not easy keeping your teeth and gums plaque-free while wearing braces. But with a little extra time and effort, a few helpful tools and your dentist's support, you can maintain a healthy mouth during orthodontic treatment.

The longer many health problems go on, the worse they become. Treating them as early as possible could stop or slow their development.
That holds true for poor bites: while we can certainly correct them later in life, it's often better to "intercept" the problem during childhood. Interceptive orthodontics attempts to do this with treatments that influence how the jaws and other mouth structures develop during childhood. Many of these techniques are usually best implemented before puberty.
For example, some very complex problems called cross bites can occur if the upper jaw grows too narrowly. We might be able to stop this from happening by using an orthodontic appliance called a palatal expander during the childhood years. It works because the bone at the center of the palate (roof of the mouth) has a gap running back to front until the early teens when the gap closes.
We fit the palatal expander up under and against the palate, then extend out metal arms from a center mechanism to the back of the upper teeth that exert outward pressure on them. This widens the center gap, which the body continually fills with bone as the device gradually exerts more pressure. Over time this causes the jaw to widen and lessens the cross bite. Timing, though, is everything: it's most effective before the gap closes.
Another way to aid jaw growth is a Herbst appliance, a hinged device that alters the movement of the jaws. As a child wears it, a Herbst appliance draws the lower jaw forward to develop more in that direction. Like the palatal expander, it's best used before significant jaw growth occurs.
These are just two examples of techniques and tools that can guide structural growth and prevent bite problems. Because they're most effective in the early years of oral development, your child should undergo an orthodontic evaluation as early as age 6 to see if they need and can benefit from an interceptive treatment.
Interceptive orthodontics can stop or at least slow a growing bite problem. The effort and expense now could save you much more of both later on.

You’ve invested a lot of time and money in orthodontic treatment to improve your smile. If you’re not careful, though, your teeth could actually move back to their old positions. The reason why is related to the same natural tooth-moving mechanism we use to straighten teeth in the first place.
Teeth are held in place by an elastic, fibrous tissue called the periodontal ligament lying between the teeth and the jawbone and attaching to both with tiny collagen fibers. The periodontal ligament allows for incremental tooth movement in response to pressure generated around the teeth, as when we chew (or while wearing braces).
Unfortunately, this process can work in reverse. Out of a kind of “muscle memory,” the teeth can revert to the older positions once there’s no more pressure from the removed braces. You could eventually be right back where you started.
To avoid this, we have to employ measures to hold or “retain” the teeth in their new positions for some time after the braces come off. That’s why we have you wear a dental appliance called a retainer, which maintains tooth position to prevent a relapse. Depending on what’s best for your situation, this could be a removable retainer or one that’s fixed to the teeth.
Patients typically wear a retainer around the clock in the immediate period after braces, and then eventually taper off to just nighttime wear. Younger patients must wear one for several months until the new teeth positions become more secure and the chances of a rebound diminish. For older patients who’ve matured past the jaw development stage, though, wearing a retainer may be a permanent necessity to protect their smile.
Retainer wear can be an annoyance, but it’s an absolute necessity. Think of it as insurance on your investment in a new, more attractive smile.
