Moving teeth through orthodontics may involve more than simply wearing braces. There are many bite conditions that require extra measures before, during or after traditional orthodontic treatment to improve the outcome.
One such measure is extracting one or more teeth. Whether or not we should will depend on the causes behind a patient's poor dental bite.
Here, then, are 4 situations where tooth extraction before orthodontics might be necessary.
Crowding. This happens when the jaw isn't large enough to accommodate all the teeth coming in. As a result, later erupting teeth could erupt out of position. We can often prevent this in younger children with space maintainers or a palatal expander, a device which helps widen the jaw. Where crowding has already occurred, though, it may be necessary to remove selected teeth first to open up jaw space for desired tooth movement.
Impacted teeth. Sometimes an incoming tooth becomes blocked and remains partially or fully submerged beneath the gums. Special orthodontic hardware can often be used to pull an impacted tooth down where it should be, but not always. It may be better to remove the impacted tooth completely, as well as its matching tooth on the other side of the jaw to maintain smile balance before orthodontically correcting the bite.
Front teeth protrusion. This bite problem involves front teeth that stick out at a more horizontal angle. Orthodontics can return the teeth to their proper alignment, but other teeth may be blocking that movement. To open up space for movement, it may be necessary to remove one or more of these obstructing teeth.
Congenitally missing teeth. The absence of permanent teeth that failed to develop can disrupt dental appearance and function, especially if they're near the front of the mouth. They're often replaced with a dental implant or other type of restoration. If only one tooth is missing, though, another option would be to remove the similar tooth on the other side of the jaw, and then close any resulting gaps with braces.
Extracting teeth in these and other situations can help improve the chances of a successful orthodontic outcome. The key is to accurately assess the bite condition and plan accordingly.

After living with braces for a couple of years, the “big reveal” finally happens and you see your new smile for the first time. But then you’re told you have to wear another mouth appliance—around the clock to start and then just at night. After all the new smile excitement, wearing a retainer can be a little anticlimactic.
But this part of your orthodontic treatment is as important as the earlier tooth movement phase. That’s because your new “forever smile” doesn’t necessarily come with a “forever” guaranty. In fact, your teeth could quickly begin moving back to where they were before braces if you don’t wear a retainer.
The reason why is because of a tough but elastic gum tissue called the periodontal ligament. This ligament lies between the teeth and the jawbone, attaching to both through tiny extending fibers. The periodontal ligament actually does most of the anchoring work to hold your teeth in place.
The ligament is also why we’re able to move your teeth to different positions: As braces apply pressure to the teeth and jaw in the direction of desired movement, the ligament remodels itself to allow the teeth to take up these new positions.
The tissues involved, though, still retain a kind of “memory” of where the teeth used to be. This creates an immediate tendency for the teeth to revert to these old positions. To prevent this, we use a retainer that when worn keeps or “retains” the teeth in their new positions until they’ve stabilized and the old tissue “memory” fades.
There are different types of retainers, some removable and some fixed in place. Choosing the best one for a particular patient will depend on the complexity of the bite treatment, the patient’s age and level of self-responsibility and the preferences of the orthodontist. Whichever type of retainer you eventually use, it’s important you wear it to preserve all of the time and effort that went into transforming your smile.
Wearing a retainer might not be high on your “exciting things to do” list. But it’s the best way to guarantee you’ll enjoy your new smile for years to come.

Braces are a common experience among teens and pre-teens. And although the treatment can be a major financial undertaking, more and more families pursue it to help their child attain a straighter, more attractive smile.
But orthodontics isn’t first and foremost a cosmetic treatment. Although an improved appearance is a benefit, the main reason for treatment is therapeutic—it can improve your child’s current and future dental health.
The teeth’s relationship to the jaws and gums makes moving them possible. Rather than simply being fixed within their jawbone socket, teeth are actually held in place by a strong, elastic tissue called the periodontal ligament. The ligament lies between the teeth and jawbone and attaches to both with tiny extending fibers. This attachment secures the teeth in place.
But the ligament also has a dynamic quality—it can reshape itself when necessary and allow teeth to move gradually into new positions. This is most necessary during the early years of mouth and jaw development, but it can also occur throughout life. Orthodontics takes advantage of this mechanism by applying precise pressure to the teeth in the direction of desired movement. The periodontal ligament does the rest by reshaping and allowing the teeth to move in response to this pressure.
The result is straighter teeth and a more normal bite. With the teeth now where they should be, it’s also easier to clean them of disease-causing dental plaque, whereas misaligned teeth are more prone to plaque accumulation that can be difficult to remove. And because the whole mouth including teeth are involved when we talk, teeth positioned in a more normal bite will improve speech.
Orthodontics is a long-term process, often encompassing more than the actual time wearing braces. Both orthodontists and pediatric dentists recommend a bite evaluation by an orthodontist around the age of 6. If it does appear an abnormal bite is forming, it may be possible to intervene and stop or at least slow the development. This could have a more positive impact on any future treatment.
Braces and other treatments can make a difference in your child’s self-image and social relationships. But the main beneficiary will be their dental health.

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.

Applying braces or clear aligners to move misaligned teeth is only part of an orthodontist's overall mission to eliminate poor bites (malocclusions). Sometimes a malocclusion isn't caused by the teeth at all—the size of the jaw is the problem!
One type in particular, a cross-bite, often happens because the upper jaw has developed too narrowly. As a result, many of the upper teeth fit inside the lower, the opposite of normal. But a tool called a palatal expander can alleviate the problem if it's applied at an early enough age.
The device works because the upper jawbone initially forms as two halves that fit together along a center line in the roof of the mouth (the palate) running from the back of the mouth to the front. These two bone halves remain separate during childhood to facilitate jaw growth, but eventually fuse around puberty.
Consisting of two sets of wire arms joined together by a hinge mechanism in the middle, the expander device is positioned up against the palate. The orthodontist extends each arm to press against the inside of the back teeth, then adds more outward pressure by turning the mechanism in the middle with a small key. During wear, the patient or caregiver will turn the mechanism in the same way to keep up the pressure on the two sides of the jaw.
This continual pressure keeps the two bones moving away from each other and maintaining a center gap between them. In response, more bone forms on the two halves to fill the gap. In time, the newly formed bone should widen the jaw enough to correct any developing malocclusion.
Timing is everything with a palatal expander—if not used before the jaw bones fuse, the patient will need a surgical procedure to separate the bones to pursue treatment. To catch the problem early enough, children should have an orthodontic evaluation on or before they turn six. An orthodontist may be able to identify this or other emerging bite problems and intervene before it becomes worse. Taking this approach can help save you and your child more expensive orthodontic treatment down the road.
