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.

After years of research, we're confident in saying that brushing and flossing daily are essential for maintaining a healthy mouth. A mere five minutes a day performing these tasks will significantly lower your risk of dental disease.
We're also sure about the essentials you'll need to perform these tasks: a soft-bristled toothbrush using fluoride toothpaste, and a roll (or picks) of dental floss. The only deviation might be a water flosser appliance instead of flossing thread.
Unfortunately, some folks deviate even more from the norm for both of these tasks. One of the strangest is a social media trend substituting regular toothpaste with substances containing activated charcoal. The proponents of brushing with charcoal claim it will help whiten teeth and kill harmful microorganisms. People brushing with a black, tarry substance also seem to make for good “gross-out” videos.
There's no substantial evidence to support these claims. Perhaps proponents of charcoal's whitening ability are assuming it can remove stains based on its natural abrasiveness. It could, however, remove more than that: Used over time, charcoal could wear down the protective enamel coating on your teeth. If that happens, your teeth will be more yellow and at much greater risk for tooth decay.
When it comes to flossing (or more precisely, removing food material from between teeth), people can be highly inventive, substituting what might be at hand for dental floss. In a recent survey, a thousand adults were asked if they had ever used household items to clean between their teeth and what kind. Eighty percent said they had, using among other things twigs, nails (the finger or toe variety) and screwdrivers.
Such items aren't meant for dental use and can harm tooth surfaces and gum tissues. Those around you, especially at the dinner table, might also find their use off-putting. Instead, use items approved by the American Dental Association like floss, floss picks or toothpicks. Some of these items are small enough to carry with you for the occasional social “emergency.”
Brushing and flossing can absolutely make a difference keeping your teeth and gums healthy. But the real benefit comes when you perform these tasks correctly—and use the right products for the job.
