UnderstandingtheAgingProcessLeadstoMoreEffectiveOrthodontics

If you’ve ever looked at younger photos of yourself, you’re sure to notice differences with your present appearance. Of course, your basic features might appear much the same. But maybe your lips seemed a little thicker back then, or your nose a bit less prominent.

This is because your facial features don’t stop growing when you reach adulthood—they continue to change throughout your life. For example, lips reach their maximum thickness by around age 14 for girls or age 16 for boys; they’ll remain at that level of thickness for a few years before gradually thinning throughout adulthood. The nose will also continue to grow, becoming more prominent especially as changes in the lower part of the face can make the chin appear shorter.

Although each of us ages at different rates and in different ways, these general physical trends are somewhat predictable. That’s why we can use the knowledge of how our facial physiology changes with age to fine tune orthodontic or other cosmetic dental treatments. The most optimum approach is to consider treatment in the early stages of bite development during childhood or early adolescence.

This means we’re doing more than correcting a patient’s current bite: we’re also taking into account how tooth movement now might affect the jaw and facial structures later in life. By incorporating our understanding of age-related changes into our treatment we might be able to provide some hedge against the effects of aging.

This approach starts with early comprehensive dental care, preferably before a child’s first birthday, and an orthodontic evaluation at around age 6 to assess bite development. It may also be necessary to initiate interceptive treatment at an early age to lessen or even eliminate a growing bite problem to help ease the extent of future treatment. And if a bite requires correction, early evaluation can help create a timetable for effective treatment in later years.

Taking this approach can correct problems now affecting both dental health and appearance. But by acknowledging the aging process in our treatments, we can build the foundation for a beautiful smile well into the future.

RemovingTeethCouldImproveanOrthodonticOutcome

Teeth crowding is a difficult bite problem (malocclusion) that often involves the entire jaw structure to be evaluated. Normally occurring when the jaw doesn’t have adequate space for normal tooth eruption, teeth coming in later put pressure on other teeth, causing them to develop improperly.

Crowding also makes it difficult to realign teeth with braces because there’s simply not enough room for sufficient movement to take place. The solution may then be to consider the removal of some of the teeth to create enough space for orthodontic treatment.

Not just any tooth can be removed, however — we must first conduct a careful analysis to determine which can be removed to facilitate optimum movement of the remaining teeth without disrupting normal mouth function or affecting appearance. The teeth most frequently removed for this purpose are the bicuspids, located between the cuspids or eyeteeth (which are positioned directly under the eyes) and the molars, the largest teeth in the back of the mouth. Sometimes one premolar tooth on each side of the jaw can be removed without sacrificing future form or function.

There are a few important considerations we must keep in mind when extracting teeth for orthodontic reasons; perhaps the most important is preserving bone at the extraction site. Because continuing bone growth depends on the forces generated by teeth when we bite or chew, bone near a missing tooth socket will tend to diminish over time. If there’s insufficient bone during orthodontic treatment, it may result in gum recession and root exposure — not only damaging to the teeth themselves but also to a person’s smile appearance. To avoid this, we sometimes will consider inserting a bone graft, which will stimulate bone growth, into the empty socket immediately after extraction. While this isn’t commonly done, it’s being considered if the patient’s bone is thin and a concern during healing.

We must also consider how to accommodate other, unrelated tooth loss to assure the final result is visually appealing. It may be necessary in these cases to maintain the space at the missing tooth site for a future restoration once the orthodontics is completed. This takes planning as well as the use of restorations like dental implants, bridges or partial dentures.

Regardless of your bite issues, the field of orthodontics has the appliances and techniques to overcome even the most complicated condition. When necessary, using procedures like tooth extraction can help turn an unappealing, dysfunctional bite problem into a beautiful smile.

AnAssortmentofOrthodonticToolshelpsusSolveComplexBiteProblems

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.

AnEarlyOrthodonticEvaluationMayAlerttoDevelopingBiteProblems

Lately, you’ve noticed your young child’s primary teeth don’t appear to be coming in straight. Is it a problem?

The answer to that question is best answered by an early orthodontic evaluation performed by an orthodontist. It’s advisable for a child as young as 7 to undergo such an exam.

While a child’s primary teeth have a short life span of a few years, that doesn’t make them less important than the permanent teeth that replace them. In fact, they’re extremely influential for permanent tooth development — each one serves as a guide for its replacement to erupt in a proper position. A future malocclusion (bad bite) that becomes more apparent later in life would have been well underway years before.

Orthodontists have the training and expertise to spot these emerging problems in their early stages. Early detection can reduce the extent — and costliness — of future orthodontic treatment by introducing preventative or interceptive measures — even while there’s still a mix of primary and permanent teeth in the mouth. For example, a child wearing a simple type of retainer that influences the development of the bite could minimize or even correct a growing malocclusion.

You can also take advantage of opportunities to discover potential orthodontic problems early through a general or pediatric dentist. By having regular dental cleanings and checkups, the dentist might observe early bite development that should be reviewed by an orthodontist. If not, it’s still a good idea to undergo an orthodontic evaluation no later than age 7.

Given the stage of jaw and facial structure development, waiting until puberty to focus on orthodontic problems may be too late for some problems — and much more expensive than if caught and treated earlier. Getting ahead of these issues earlier in your child’s dental development will help ensure they’ll have a healthy bite throughout their life.

ARetainerHelpsYouKeepYourNewSmileAfterBraces

Moving your teeth to a more functional and attractive alignment is a big undertaking. You can invest months — even years — and a lot of expense to correct a bad bite. But all that effort could be for nothing if your teeth return to their original positions.

The very aspect of dental physiology that makes orthodontics possible can work against you in reverse. Your teeth are not actually rigidly fixed in the bone: they're held in place by an elastic gum tissue known as the periodontal ligament. The ligament lies between the tooth and the bone and attaches to both with tiny fibers.

While this mechanism holds the teeth firmly in place, it also allows the teeth to move in response to changes in the mouth. As we age, for example, and the teeth wear, the ligament allows movement of the teeth to accommodate for the loss of tooth surface that might have been created by the wear.

When we employ braces we're changing the mouth environment by applying pressure to the teeth in a certain direction. The teeth move in response to this pressure. But when the pressure is no longer there after removing the braces or other orthodontic devices, the ligament mechanism may then respond with a kind of “muscle memory” to pull the teeth back to where they were before.

To prevent this, we need to help the teeth maintain their new position, at least until they've become firmly set. We do this with an oral appliance known as a retainer. Just as its name implies it helps the teeth “retain” their new position.

We require most patients to initially wear their retainer around the clock. After a while we can scale back to just a few hours a day, usually at nighttime. Younger patients may only need to wear a retainer for eighteen months or so. Adults, though, may need to wear one for much longer or in some cases permanently to maintain their new bite.

Although having to wear a retainer can be tedious at times, it's a crucial part of your orthodontic treatment. By wearing one you'll have a better chance of permanently keeping your new smile.
