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.

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.

Orthodontic braces are a familiar sight, especially among tweens and teens: metal brackets and wires attached to the front of the teeth for all to see. Now imagine the opposite: much the same hardware, but now positioned out of sight on the back of the teeth.
It's not your imagination: It's the latest development in orthodontic technology called lingual braces. Developed simultaneously by two orthodontists in Japan and Beverly Hills, these appliances are placed on the tongue or “lingual” side of the teeth rather than the traditional labial or “lip-side.”
Generally, lingual braces can correct any bite problem labial braces can. The difference lies in how each method does its job: Traditional braces exert pressure or “push” against the teeth, while lingual braces “pull” the teeth into better alignment.
So, why choose lingual over labial? For one, they're “invisible” to others: all the hardware is on the backside of the teeth, out of sight. They're also not as readily exposed to blunt force facial trauma, which can damage traditional braces (a driving impetus for the Japanese doctor to develop them for his martial arts patients, and his American counterpart for a law enforcement patient working in a rough area).
Patients may also prefer lingual braces over removable clear aligners, another popular tooth-movement option. Fixed lingual braces achieve the same quality of “invisibility” as removable aligners, but without the inconvenience of removing them as patients must with aligners for eating, snacking or cleaning.
They can, however, be costly, running 15-35% more than labial braces. Patients may also have difficulty adjusting to them because they can affect speech and tongue comfort. However, any discomfort and initial regret with choosing lingual braces tends to fade as most patients grow more accustomed to them after a week or so.
There's one other “perk” to lingual braces—unlike patients with traditional braces who have to wait for their removal to see the finished bite correction, patients with lingual braces get an unobstructed view of their progress all during wear. That can definitely boost morale during the long treatment period!
Lingual braces haven't been around long, so not every orthodontist offers them. But the list is growing, and there soon may be a provider near you for this new teeth-straightening alternative.

What do a teenager with a poor bite, a senior citizen with multiple missing teeth or a middle-aged person with a teeth grinding habit all have in common? They may all depend on a dental appliance for better function or appearance.
There’s a wide variety of removable dental appliances like clear aligners or retainers for orthodontic treatment, dentures for tooth loss or night guards to minimize teeth grinding, just to name a few. But while different, they all share a common need: regular cleaning and maintenance to prevent them from triggering dental disease and to keep them functioning properly.
The first thing to remember about appliance cleaning is that it’s not the same as regular oral hygiene, especially if you have dentures. While they look like real teeth, they’re not. Toothpaste is a no-no because the abrasives in toothpaste designed for tooth enamel can scratch appliance surfaces. These microscopic scratches can develop havens for disease-causing bacteria.
Instead, use liquid dish detergent, hand soap or a specific cleaner for your appliance with a different brush from your regular toothbrush or a specialized tool for your particular appliance. Use warm but not very hot or boiling water: while heat indeed kills bacteria, the hot temperatures can warp the plastic in the appliance and distort its fit. You should also avoid bleach—while also a bacteria killer, it can fade out the gum color of appliance bases.
Be sure you exercise caution while cleaning your appliance. For example, place a towel in the sink basin so if the appliance slips from your hands it’s less likely to break hitting the soft towel rather than the hard sink. And while out of your mouth, be sure you store your appliance out of reach of small children and pets to avoid the chance of damage.
Cleaning and caring for your appliance reduces the risk of disease that might affect your gums or other natural teeth. It will also help keep your appliance working as it was designed for some time to come.
About one-quarter of people have teeth that never developed. While most of these congenitally missing teeth are wisdom teeth, they can also include premolars or lateral incisors (the teeth right next to the two front teeth, the central incisors).
Missing teeth can have an adverse effect on smile appearance. But that’s not all: because each type of tooth performs a specific function, one or more missing teeth can lead to bite problems and disruption of dental function. In the case of missing lateral incisors, the canines (eye teeth) normally positioned beside and toward the back of the mouth from them may begin to drift into the empty space and grow next to the central incisors. This can result in greater difficulty chewing and a smile that “doesn’t look right.”
To correct this situation, we must often first attempt to orthodontically move any out of place teeth to their normal positions. This re-establishes the space needed for the missing teeth to be replaced, which we can then restore with prosthetic (artificial) teeth. If the permanent restoration of choice involves dental implants, we’ll usually need to wait until the completion of jaw development around early adulthood. In the mean time, we can use a retainer appliance to hold the teeth in their new positions with prosthetic teeth attached to fill the empty space for a better smile appearance in the interim.
The real issue is timing—beginning orthodontic treatment when appropriate to a person’s oral development, as well as completing the implant restoration when the mouth has matured sufficiently. There are other considerations such as bone volume, which may have diminished due to the missing teeth. At some point we may need to consider grafting to build up the bone sufficiently to support dental implants.
This all may entail a team approach by various specialties like orthodontics, periodontics and implantology. Working together and coordinating within a timely schedule, a mouth and smile marred by undeveloped teeth can be transformed.
