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.

Infancy is perhaps the only time in a person's life where a smile with just a few tiny teeth is still endearing. More will come—and then each will gradually depart, succeeded by permanent replacements.
That short lifespan, though, doesn't diminish their importance. Primary teeth not only provide children the ability to eat solid food and develop speech, but they set the stage for future dental health.
The latter arises from primary teeth's role as placeholders for incoming permanent teeth. Because permanent teeth eruption occurs in stages, primary teeth prevent earlier erupted teeth from drifting into the space intended for a later tooth. If they're lost prematurely and other teeth crowd into the space, the intended tooth may not have enough room to erupt properly, cascading from there into a poor bite (malocclusion).
The most common reason for premature loss is an aggressive form of tooth decay in children under 6 called early childhood caries (ECC). About one in four U.S. children encounter ECC, with those in poverty at higher risk. Infection in one tooth can spread to others, including newly erupted permanent teeth.
The goal then is to prevent ECC as much as possible, and initiate prompt treatment should it still occur. A good prevention strategy has two prongs: the actions and habits of parents or caregivers; and the prevention and treatment measures taken by dental providers.
At home, it's important that you wipe your newborn's gums with a clean, damp cloth after each feeding to reduce bacterial growth. As teeth erupt, switch then to gentle brushing with a rice grain-sized amount of baby toothpaste. You should also limit their sugar consumption, including not allowing them to sleep with a bedtime bottle of any liquid other than water.
It's also important that you start your child's regular dental visits around their first birthday. This allows us to detect any developing cavities, as well as apply sealants and topical fluoride to help prevent decay. And should a cavity develop, regular visits help ensure prompt treatment to preserve the tooth.
Your child's set of primary teeth only last a few short years, but their contribution echoes for a lifetime. Taking these measures to protect them from tooth decay ensures they'll fully make that contribution.

Think no one is looking at your smile when you’re out in public? Nick Jonas’ recent experience might convince you otherwise. While the Jonas Brothers were performing during the 2020 Grammys, fans watching on television picked up on some dark matter between his teeth.
To say Twitter lit up is an understatement. For many, it was that thing you couldn’t unsee: Forget the performance, what was that between his teeth? Jonas later fessed up by tweeting, “…At least you all know I eat my greens.”
We’re sure Nick and his brothers take care of their teeth, as most any high-profile entertainer would. You can probably attribute his dental faux pas to trying to squeeze in some nourishment during a rushed performance schedule.
Still, the Grammy incident (Spinachgate?) shows that people do notice when your teeth aren’t as clean as they should be. To avoid that embarrassment, here are some handy tips for keeping your teeth looking their best while you’re on the go.
Start with a clean mouth. You’re more apt to collect food debris during the day if you have built-up plaque on your teeth. This sticky bacterial biofilm attracts new food particles like a magnet. Remove plaque by thoroughly brushing and flossing before you head out the door.
Rinse after eating. Although your saliva helps clear leftover food from your mouth, it may not adequately flush away all the debris. You can assist this process by swishing and rinsing with clean water after a meal.
Keep a little floss handy. Even after rinsing, stubborn bits of food can remain lodged between teeth. So just in case, keep a small bit of emergency floss (or a floss pick) in your purse or wallet to remove any debris you see or feel between your teeth.
Watch what you eat. Some foods—like popcorn, sticky snacks or fibrous vegetables—are notorious for sticking in teeth. Try to avoid eating these foods right before a public appearance where your smile may be critical.
And here’s an added bonus: Not only will these tips help keep your smile attractive on the go, they’ll also help keep it healthy. Rinsing with water, for example, helps lower your mouth’s acid level after eating, a prime factor in tooth decay. And flossing, both as a regular practice and for occasional stuck food, decreases plaque and subsequently your risk of tooth decay and gum disease.
Remember, a healthy mouth is the starting place for a beautiful smile. Keep it that way with dedicated hygiene habits at home or on the go.
