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.

You may not always be able to tell if your child's bite isn't developing properly. Â That's why you should have them undergo an orthodontic evaluation around age 6 to uncover any emerging problems with tooth misalignment.
Still, there are some visible signs all's not well with their bite. As the primary (baby) teeth give way, the permanent teeth erupt sequentially around ages 6 to 8. As they come in, you should notice that each tooth fits uniformly next to each other without excessive gaps or, on the other end of the spectrum, not crowded together in crooked fashion. Upper teeth should also fit slightly over the lower teeth when the jaws are shut.
If their teeth appearance deviates from these norms, they may have a bite problem. Here are 4 abnormalities you should watch for.
Underbite or deep bite. As we mentioned, the front teeth should cover the lower teeth with the jaws shut. In an underbite, the reverse happens — the lower teeth are in front of the upper teeth. It's also a problem if the upper teeth cover the lower teeth too much (often referred to as “deeply”).
Open bite. This occurs when there's a gap between the upper and lower front teeth while the jaws are shut together. One possible cause is late thumb sucking, which can put undue pressure on the front teeth and cause them to develop too far forward while forcing the bottom front teeth further backwards.
Crossbites. This kind of bite occurs when some of the teeth don't fit properly over their counterparts, while others do. Crossbites can occur anywhere in the mouth, for example the upper front teeth fitting behind the lower front teeth while the back teeth overlap normally, or the reverse (front normal, back abnormal).
Misalignments and Abnormal Eruptions. Sometimes upper teeth may align too far forward, a situation known as protrusion. Conversely, lower teeth (or the jaw itself) may come in too far back (retrusion). Because a primary tooth might be out of position or not lost in the proper sequence, a permanent tooth might noticeably erupt out of its proper position.
If you notice any of these situations with your child's teeth see your dentist or orthodontist soon for a full examination. If caught early, we may be able to take action that will lessen or even eliminate the problem.
