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.

July is Park and Recreation Month, when we Americans celebrate our ongoing love affair with the great outdoors. Since Yellowstone became our first national park in 1872, we've been passionate about preserving our country's natural resources for the enjoyment of this and future generations. As dental providers, it also reminds us of something else worth preserving: our natural teeth.
Not that we don't have amazing restoration options for lost teeth. With the advent of dental implants, you can get a replacement that looks and functions like the real thing. But even though implants are an exceptional choice, they are still not superior in terms of the overall health protections of real teeth. So unless keeping a sick tooth would cause more harm than good, going the extra mile to save it is often the best choice for long-term dental health.
First, though: Preserving natural teeth doesn't start when they're in peril, but with daily and regular care. The “daily” part is your job—brushing and flossing to remove dental plaque, the single biggest factor in the occurrence of dental disease. Doing this every day is critical in preserving your teeth in the long run.
The “regular” part is our job—professional teeth cleaning every six months. Using special tools, we clear away any plaque you might have missed, plus any tartar (hardened plaque), which can't be removed with brushing and flossing. Routine dental visits also give us a chance to check your teeth and gums for any signs of developing decay or infection.
That's important because although prevention can minimize your risk of tooth decay or gum disease, it can't eliminate the risk altogether. If disease does occur, we'll need to treat it as soon as possible to avoid the worst case scenario of a lost tooth. Often, root canal therapy can save a tooth that is diseased on the inside. Using dental treatments, even extensive ones, as needed to preserve teeth remains the best way to optimize dental health.
Teeth treated for disease may still be viable, but they may look the worse for wear. Fortunately, we can often give unattractive teeth a cosmetic makeover. Tooth-colored fillings and porcelain veneers or crowns, for example, can completely change a tooth's appearance for the better. With the right enhancement procedure, you can keep both your natural teeth and your smile.
It takes an ongoing effort to maintain your natural teeth. But just like preserving the natural surroundings of our national parks, it's well worth the effort.

Dental implants are far and away the most “tooth-like” restoration available today for missing teeth. Not only do they look real, they also mimic dental anatomy in replacing the tooth root.
To install an implant, though, requires a minor surgical procedure. And, as with any surgery, that includes a slight risk for a post-surgical infection. For most patients this isn't a major concern—but it can be for people with certain medical conditions.
One way to lessen the risk for implant patients whose health could be jeopardized by an infection is to prescribe a prophylactic (preventive) antibiotic before implant surgery. The American Dental Association (ADA) recommends the measure for patients with artificial heart valves, a history of infective endocarditis, a heart transplant and other heart-related issues.
In the past, their recommendation also extended to people with joint replacements. But in conjunction with the American Academy of Orthopedic Surgery (AAOS), the ADA downgraded this recommendation a few years ago and left it to the physician's discretion. Indeed, some orthopedic surgeons do recommend antibiotic therapy for patients before surgical procedures like implantation for up to two years after joint replacement.
These changes reflect the ongoing debate over the proper use of antibiotics. In essence, this particular argument is over risks vs. benefits: Are pre-surgical antibiotics worth the lower infection risk for patients at low to moderate risk in return for increased risk of allergic reactions and other side effects from the antibiotic? Another driver in this debate is the deep concern over the effect current antibiotic practices are having on the increasing problem of antibiotic-resistant bacteria.
As a result, dentists and physicians alike are reevaluating practices like prophylactic antibiotics before procedures, becoming more selective on who receives it and even the dosage levels. Some studies have shown, for example, that a low 2-gram dose of amoxicillin an hour before the procedure can be effective with much lower risks for side effects.
If you're considering dental implants and you have a medical condition you think could be impacted by the procedure, discuss the matter with your dentist and physician. It may be that pre-surgical antibiotics would be a prudent choice for you.
