If you press your tongue against your teeth, unless something is badly wrong they won't budge. In fact, your teeth are subjected to a fair amount of pressure each day as you chew and eat, and yet they remain firmly in place.
But there's a deeper reality—your teeth do move! No, it's not a paradox—the gum and bone tissues that hold your teeth in place allow for slight, imperceptible changes in the teeth's position. Their natural ability to move is also the basis for orthodontics. Here are 3 more facts you may not know about your teeth's natural ability to move.
Teeth are always on the move. Teeth are held firmly within the jawbone by an elastic gum tissue called the periodontal ligament and a thin layer of bony-like material called cementum. In response to pressure changes, though, the bone dissolves on the side of the teeth in the direction of pressure and then rebuilds behind it, solidifying the teeth's new position, a process that happens quite slowly and incrementally. And it will happen for most of us—some studies indicate more than 70% of people will see significant changes in their bite as they age.
Orthodontics works with the process. Orthodontic appliances like braces or clear aligners apply targeted pressure in the direction the orthodontist intends the teeth to move—the natural movement process does the rest. In the case of braces, a thin metal wire is laced through brackets bonded to the front of the teeth and then anchored, typically to the back teeth. The orthodontist incrementally tightens the wire against its anchors over time, encouraging tooth movement in response to the pressure. Clear aligners are a series of removable trays worn in succession that gradually accomplish the same outcome.
Watch out for the rebound. That nice, straight smile you've gained through orthodontics might not stay that way. That's because the same mechanism for tooth movement could cause the teeth to move back to their former positions, especially right after treatment. To avoid this outcome, patients need to wear a retainer, an appliance that holds or "retains" the teeth in their new positions. Depending on their individual situations and age, patients may have to wear a retainer for a few months, years or from then on.

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.

It’s a common sight to see someone wearing braces—and not just teens or pre-teens. In the last few decades, people in their adult years (even late in life) are transforming their smiles through orthodontics.
If you’re an adult considering treatment to straighten your teeth, this particular dental specialty might be an unfamiliar world to you. Here are 3 things you may not know about orthodontics.
Orthodontic treatment cooperates with nature. There would be no orthodontics if teeth couldn’t move naturally. Teeth are actually held in place by an elastic tissue called the periodontal ligament that lies between the teeth and bone. Small fibers from the ligament tightly attach to the teeth on one side and to the bone on the other. Although it feels like the teeth are rigidly in place, the ligament allows for micro-movements in response to changes in the mouth. One such change is the force applied by orthodontic appliances like braces, which causes the bone to remodel in the direction of the desired position.
Treatment achieves more than an attractive smile. While turning your misaligned teeth into a beautiful, confident smile is an obvious benefit, it isn’t the only one. Teeth in proper positions function better during chewing and eating, which can impact digestion and other aspects of health. Misaligned teeth are also more difficult to keep clean of bacterial plaque, so straightening them could help reduce your risk of tooth decay or periodontal (gum) disease.
Possible complications can be overcome. Some problems can develop while wearing braces. Too much applied force could lead to the roots dissolving (root resorption), which could make a tooth shorter and endanger its viability. Braces can also contribute to a loss of calcium in small areas of tooth enamel, which can make the teeth more vulnerable to oral acid attack. However, both these scenarios can be anticipated: the orthodontist will watch for and monitor signs of root resorption and adjust the tension on the braces accordingly; and diligent oral hygiene plus regular dental cleanings will help prevent damage to the tooth enamel.
