While retainers are often viewed as a nuisance, they’re crucial to protect the gains made with bite correction. Without them, all of the progress achieved through braces or clear aligners could be lost.
Here’s why: The same elastic gum tissue called the periodontal ligament that holds teeth in place also allows them to move incrementally in response to changes in the mouth. That’s why we can move teeth with braces or aligners, which put pressure on the teeth toward a desired direction of movement while the periodontal ligament does the rest.
But the mechanics can also work in reverse: With pressure relieved when the braces are removed, the teeth could revert to their original positions through a kind of “muscle memory.” The light pressure provided by a retainer is enough to keep or “retain” teeth in their new positions.
The best known retainer is a removable appliance. Initially, a patient wears it continuously and only takes it out during oral hygiene. Wear duration may later be reduced to night time only and eventually not at all, depending on a patient’s individual needs.
While effective, removable retainers do have some downsides. Like braces, they’re visible to others. And because they’re removable, they’re frequently misplaced or lost, leading to the added expense of a new one.
An alternative is a bonded retainer, a thin piece of wire attached to the back of the newly moved teeth to keep them in place. Because it’s behind the teeth it’s not visible—and there’s no misplacing it because only a dentist can take it out.
A bonded retainer is a good option, especially if a patient is immature and not as diligent about wearing or keeping up with their appliance. But it can make flossing difficult to perform, and if they’re removed or broken prematurely, the teeth could revert to their former positions.
If you decide to go with a bonded retainer, be sure you get some tips from your dental hygienist on how to floss with it. And if you decide later to have it removed early, be sure to replace it with a removable retainer. Either of these two options can help you keep your new and improved smile.

The monarchs of the world experience the same health issues as their subjects—but they often tend to be hush-hush about it. Recently, though, the normally reticent Queen Elizabeth II let some young dental patients in on a lesser known fact about Her Majesty's teeth.
While touring a new dental hospital, the queen told some children being fitted for braces that she too “had wires” once upon a time. She also said, “I think it's worth it in the end.”
The queen isn't the only member of the House of Windsor to need help with a poor bite. Both Princes William and Harry have worn braces, as have other members of the royal family. A propensity for overbites, underbites and other malocclusions (poor bites) can indeed pass down through families, whether of noble or common lineage.
Fortunately, there are many ways to correct congenital malocclusions, depending on their type and severity. Here are 3 of them.
Braces and clear aligners. Braces are the tried and true way to straighten misaligned teeth, while the clear aligner method—removable plastic mouth trays—is the relative “new kid on the block.” Braces are indeed effective for a wide range of malocclusions, but their wires and brackets make it difficult to brush and floss, and they're not particularly attractive. Clear aligners solve both of these issues, though they may not handle more complex malocclusions as well as braces.
Palatal expanders. When the upper jaw develops too narrowly, a malocclusion may result from teeth crowding into too small a space. But before the upper jaw bones fuse together in late childhood, orthodontists can fit a device called a palatal expander inside the upper teeth, which exerts gentle outward pressure on the teeth. This encourages more bone growth in the center to widen the jaw and help prevent a difficult malocclusion from forming.
Specialized braces for impacted teeth. An impacted tooth, which remains partially or completely hidden in the gums, can impede dental health, function and appearance. But we may be able to coax some impacted teeth like the front canines into full eruption. This requires a special orthodontic technique in which a bracket is surgically attached to the impacted tooth's crown. A chain connected to the bracket is then looped over other orthodontic hardware to gradually pull the tooth down where it should be.
Although some techniques like palatal expanders are best undertaken in early dental development, people of any age and reasonably good health can have a problem bite corrected with other methods. If you are among those who benefit from orthodontics, you'll have something in common with the Sovereign of the British Isles: a healthy, attractive and straighter smile.
There are important reasons not to smoke, like minimizing your risk for deadly diseases like heart disease or lung cancer. But here's another good reason: Smoking increases your risk of gum disease and possible tooth loss. And although not necessarily life-threatening, losing your teeth can have a negative effect on your overall health.
According to the U.S. Centers for Disease Control, individuals who smoke cigarettes, cigars, pipes or e-cigarettes are twice as likely as non-smokers to develop gum disease, and four times as likely the infection will become advanced. Your risk may also increase if you're regularly exposed to second-hand smoke.
There are a number of reasons for this increased risk. For one, smokers are less likely than non-smokers to recognize they have gum disease, at least initially, because they may not display classic symptoms of an infection like red, swollen or bleeding gums. This happens because the nicotine in tobacco smoke interferes with normal blood circulation. As a result, their gums may appear healthy when they're not.
That same circulation interference can also inhibit the production and supply of antibodies to fight infection. Not only can this intensify the infection, it can also slow healing and complicate treatment. In fact, smokers are more likely to have repeated episodes of infection, a condition called refractory periodontitis.
But there is good news—smoking's effect on your gum health doesn't have to be permanent. As soon as you stop, your body will begin to repair the damage; the longer you abstain from the habit, the more your gum health will improve. For example, one national study found that former smokers who had not smoked for at least eleven years were able to achieve an equal risk of gum disease with someone who had never smoked.
Quitting smoking isn't easy, but it can be done. If abrupt cessation (“cold turkey”) is too much for you, there are medically-supported cessation programs using drugs or other techniques that can help you kick the habit. And while it may be a long road, leaving smoking behind is an important step toward improving and maintaining good dental health.
