There are an assortment of techniques and treatments in an orthodontist's toolkit, braces being the most common and best known. Of course, there wouldn't be any tools at all if teeth couldn't move naturally.
Teeth aren't directly connected to the jawbone. An elastic tissue called the periodontal ligament lies between each one, with tiny fibers attaching to the tooth on one side and to the bone on the other. The ligament's elasticity and other qualities allow micro-movements of the teeth as we bite.
The ligament can also adapt to changes in the mouth and teeth by allowing the teeth to move to different positions. That's the basic concept behind braces: we thread a thin wire through brackets attached to the teeth, which we then attach to anchor points (usually back teeth not intended to move) and apply tension to it. Gradually over time, the target teeth move.
But what if your malocclusion (poor bite) is more complicated or the back teeth can't supply enough anchorage for moving the intended teeth? That's where we take advantage of other sources of anchorage.
One such source is the patient's skull, which we can make use of through special headgear worn a few hours a day. The device consists of a strap under tension that runs around the back of the head or neck to a wire housing attached to brackets on the target teeth. If you want to “pull” the teeth forward, the strap would come over the chin, forehead or a combination of both.
We may sometimes want to isolate some teeth to move without moving nearby teeth, such as moving front teeth backward to close a space without affecting teeth further to the rear. We can create a separate anchor point in the jaw with a TAD or temporary anchorage device.
TADs are tiny screws made of stainless steel inserted temporarily into the bone. We loop an elastic band over the TAD on one end and to a bracket or tension wire attached to the target teeth on the other. When we've achieved the teeth's new position we can easily remove the TAD from the bone.
These various tools make it possible to correct difficult or complex malocclusions. They may not always look attractive, but they'll help ensure the final result is.

A lot of people don’t like dental work because they believe it will be painful or uncomfortable. There’s an anatomical reason to back up that concern — the mouth with its dense network of nerves in the teeth and gums is one of the most sensitive parts of the human body.
But modern dentistry has helped solve much of the problem of pain with advances in local anesthesia. Using substances that temporarily block electrical impulses within the nerves of a selected area of oral tissues, there’s a good chance you’ll feel little to no discomfort even during moderately invasive procedures.
Unfortunately, you might have heard some complaints from others about local anesthesia that might make you wary of it. Many of these complaints, however, aren’t fully based on all the facts. So, let’s set the record straight about local anesthesia and what you can expect.
No need to be afraid of needles. Nobody enjoys the painful prick from an injection needle, and some people are highly fearful of them. But although it’s necessary to use a needle to deliver anesthesia to deeper levels of tissue, it’s possible you won’t feel it. That’s because we’ll typically apply a topical numbing agent to the skin surface that deadens the top layers where we insert the needle.
That numb feeling afterward won’t last long. One of the chief complaints in the past about local anesthesia was the irritating numbness that could long linger after a procedure. Today, however, with more advanced anesthetics and formulae, we’re better able to gauge the duration of the medication’s effect. This has greatly reduced the length of time afterward your mouth might have that awkward numbing sensation.
Anesthesia isn’t necessary for every procedure. Unless you have hypersensitive teeth, a lot of dental procedures don’t require anesthesia. Your enamel, for example, has no nerves and actually serves as a kind of “muffler” for sensations to lessen their effect. Cleaning your teeth or removing portions of the enamel can normally be performed without the need for numbing medication.
For procedures, though, where pain could be a factor, local anesthesia can make all the difference in the world. In these cases, anesthesia is your friend — it can help you receive the dental care you need without the discomfort.
