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.

What makes an attractive smile? Of course, shiny, straight and defect-free teeth are a big factor. But there’s another equally important element: all your teeth have come in.
Sometimes, though, they don’t: one or more teeth may remain up in the gums, a condition known as impaction. And if they’re in the front like the upper canines (the pointed teeth on either side of the front four incisors) your smile’s natural balance and symmetry can suffer.
Impaction usually happens due to lack of space on a small jaw. Previously erupted teeth crowd into the space of teeth yet to come in, preventing them from doing so. As a result the latter remain hidden within the gums.
While impaction can interfere with the smile appearance, it can cause health problems too. Impacted teeth are at higher risk for abscesses (localized areas of infection) and can damage the roots of other teeth they may be pressing against. That’s why it’s desirable for both form and function to treat them.
We begin first with an orthodontic examination to fully assess the situation. At some point we’ll want to pinpoint the impacted teeth’s precise location and position. While x-rays are useful for locating impacted teeth, many specialists use cone beam CT (CBCT) technology that produces highly detailed three-dimensional images viewable from different vantage points.
If the tooth is in too extreme a position, it might be best to remove it and later replace it with a dental impact or similar restoration once we’ve completed other necessary orthodontic treatment. But if the tooth is in a reasonable position, we might be able to “move” the tooth into its proper place in the jaw in coordination with these other tooth-movement efforts to make room for it.
To begin this process, an oral surgeon or periodontist surgically exposes the tooth crown (the normally visible portion) through the gums. They then bond a small bracket to the crown and attach a small gold chain. An orthodontist will attach the other end to orthodontic hardware that will exert downward pressure on the tooth to gradually bring it into normal position.
Dealing with impacted teeth of this nature is often part of a comprehensive effort to correct the bite. If we’re successful, it could permanently transform both the smile and overall dental health.

Wearing braces takes time, but if all goes well the changes to your smile will be well worth it. In the meantime, though, you’ll have to contend with one particular difficulty—keeping your teeth clean of disease-causing, bacterial plaque.
Don’t worry, though—while keeping dental disease at bay with braces can be challenging, it is doable. Here are 4 tips for minimizing your chances of tooth decay or periodontal (gum) disease during orthodontic treatment.
Eat less sugar. Like any living organism, bacteria must eat—and they’re especially amenable to sugar. The more they have access to this favorite food source, the more they multiply—and the greater your risk of tooth decay or gum disease. Eating fewer sugary foods and snacks and more dental-friendly ones helps restrict bacteria populations in your mouth.
Brush thoroughly. Brushing with braces can be difficult, especially in areas blocked by orthodontic hardware. You need to be sure you brush all tooth and gum surfaces around your braces, including above and below the wire running through the brackets. A soft multi-tufted microline bristle brush is a good choice for getting into these hard to reach places. Brushing around braces takes more time, but it’s essential for effective plaque removal.
Use flossing tools. Flossing is important for removing plaque from between teeth—but, unfortunately, it might be even more difficult to perform with braces than brushing. If using string floss proves too daunting consider using a floss threader or a similar device that might be easier to maneuver. You can also use a water irrigator, a hand-held device that sprays water under pressure to loosen and flush away between-teeth plaque.
Keep up regular dental visits. While you’re seeing your orthodontist regularly for adjustments, you should also see your general dentist at least every six months or more. Besides dental cleaning, your dentist also monitors for signs of disease and can prescribe preventive measures like antibacterial mouth rinses. Of course, if you see abnormalities, like white spots on your teeth or red, puffy or bleeding gums, contact your dentist as soon as possible. The sooner a problem can be addressed the less impact it may have on your orthodontic treatment and overall oral health.

Your teenager is about to take a big step toward better health and a more attractive appearance — orthodontic treatment. You both know the benefits: better chewing function, lower risk of dental disease, and, of course, a straighter and more beautiful smile.
But your teen might also dread the next couple of years of wearing braces. And it's hard to blame them: although they're effective, wearing braces restricts eating certain snacks and foods, they require extra time and effort for brushing and flossing, and they're often uncomfortable to wear. And of high importance to a teenager, they may feel embarrassed to wear them.
But over the last couple of decades a braces alternative has emerged: clear aligners. This form of bite correction requires fewer food restrictions, allows greater ease in hygiene, and is considered more attractive than braces. In fact, most observers won't notice them when a wearer smiles.
Clear aligners are a series of clear plastic trays created by computer that are worn in a certain sequence. During wear each tray exerts pressure on the teeth to gradually move them in the desired direction. The patient wears a single tray for two weeks and then changes to the next tray in the sequence, which will be slightly different than the previous tray. At the end of the process, the teeth will have been moved to their new positions.
Clear aligners aren't appropriate for all bite problems. When they are, though, they offer a couple of advantages over braces. Unlike braces, a wearer can remove the aligner to brush and floss their teeth or for rare, special or important social occasions. And, of course, their appearance makes them less likely to cause embarrassment while wearing them.
In recent years, design improvements have increased the kinds of bites aligners can be used to correct. For example, they now often include “power ridges,” tiny features that precisely control the amount and direction of pressure applied to the teeth. They've also become thinner and more comfortable to wear.
If you're interested in clear aligners as a treatment option, talk with your orthodontist about whether your teen is a good candidate. If so, they could make orthodontic treatment for achieving a more attractive and healthy smile less of an ordeal.

Wearing braces isn't just for teenagers — straightening teeth can be just as viable a need when you're an adult. For example, it may be necessary to first move teeth away from an empty tooth socket before you obtain a dental implant or other restoration.
But braces could have complications, especially if you have periodontal (gum) disease. These infections caused by plaque, a thin film of bacteria and food particles, inflame and weaken gum tissues and erode supporting bone. It can be treated and brought under control — but keeping it under control requires daily brushing and flossing, along with frequent office cleanings and checkups.
Braces can make this more difficult: it's harder to brush and floss effectively through the hardware of brackets and wires, which can give plaque a chance to build up. Patients susceptible to gum disease are more likely to have re-infections while wearing braces. The hardware can also cause enamel to come in prolonged contact with acid, which can dissolve its mineral content and open the door to tooth decay.
Clear aligners are an alternative to braces that can accomplish tooth movement while minimizing infection flare-ups for people with gum disease. Aligners are a series of customized clear plastic trays worn over the teeth, with each succeeding tray incrementally moving the teeth further than the preceding one. After wearing one tray for a specified time period, you then switch to the next tray. The teeth gradually move to the desired new position over the course of the aligner series.
This option is especially advantageous for gum disease patients because the trays can be removed temporarily for brushing and flossing. There are also other benefits: we can hide a missing tooth space with a temporary false tooth attached to the aligner; and, they're nearly invisible so it won't be obvious to others you're undergoing orthodontic treatment.
Not all orthodontic situations benefit from this alternative, while some cases may call for a combination approach between aligners and braces. But in the right setting, clear aligners are a good choice for not only obtaining better teeth position, but also helping you avoid a new encounter with dental disease.
