It’s been a long road with your braces, but now they’re finally off. Hopefully the first glimpse of your new smile more than made up for the time and effort they required.
But while braces removal is a big milestone, it’s not the end of your treatment—not, that is, if you want to keep that new smile! You’ll now need to wear an appliance called a retainer for a few years or, in some cases, from now on.
Orthodontic retainers are a must after braces for the same reason braces work in the first place—your teeth can move. While the teeth attach to the jawbone via the roots, they’re firmly held in place by an elastic gum tissue network called the periodontal ligament. This tough but elastic tissue lies between the teeth and gums and attaches securely to both with tiny fibers.
While the ligament provides stability, it’s also dynamic—constantly remodeling to allow the teeth to move in response to biting pressure and other mouth factors. Orthodontists use this mechanism when moving teeth to better positions. The braces apply pressure on the teeth in the desired direction and the periodontal ligament responds as the teeth move.
Afterward, however, the ligament can still retain a kind of “muscle memory” for a time of the teeth’s old positions. Free of the pressure once supplied by the braces the teeth have a tendency, especially early on, to “rebound” to where they were.
A retainer helps prevent this by exerting just enough pressure to “retain” the teeth in their new positions. In the beginning this may require wearing the appliance around the clock, but you may be able later to reduce wear time to just a few hours a day. Rebounding is unpredictable, so you should continue to follow your orthodontist’s recommendations on retainer wear.
Wearing a retainer may seem like a drag, but it’s absolutely essential. Being diligent about it will help ensure that the beautiful smile you and your orthodontist worked so hard to obtain stays with you for years to come.

What do young saber tooth tigers, which have been extinct about 10,000 years, have in common with human kids today? At first glance, not a lot. Smilodon fatalis, the big cat of North America, reached adulthood at around age three and weighed up to 600 pounds. But these ice-age mammals are probably best known for their dagger-like canine teeth, which (as shown by many well-preserved skeletons) grew up to 7 inches long. And that’s where the comparison between kids and kitties gets interesting.
The toothy felines had primary (baby) teeth and adult teeth, which developed in a similar way to human dentition. The primary teeth came in first, persisted during the young cat’s development, and shared space in the mouth as the adult teeth were erupting (growing in) — with one big difference. According to a recent study reported in the academic journal PLOS ONE, those colossal canines grew at an astonishing rate: up to 6 millimeters per month! By comparison, human primary teeth emerge from the gums at around 0.7mm per month, while permanent teeth may grow up to 2mm per month.
It’s understandable why those tiger teeth developed so rapidly: Life in the Ice Age was hard, and predators needed every advantage just to stay alive. But while human baby teeth take longer to develop (and to go away), they, too, are vitally important.Â For one thing, the primary teeth let kids bite, chew, speak (and smile) properly, until they are replaced by adult teeth — a process that isn’t usually finished until a child reaches the age of 12-13. So those “baby” teeth allow kids to have good nutrition — and positive social interactions — for a significant part of childhood!
There’s another important thing primary teeth do before they’re gone: They help ensure that the succeeding teeth come in properly, by holding a space in the jaw that will later be filled by a permanent tooth. If baby teeth are lost prematurely, those spaces can close up, resulting in permanent teeth that emerge too close together, or in the wrong places. This condition, called malocclusion (bad bite), can usually be corrected by orthodontics. But it’s better to avoid the inconvenience (and cost) of braces, if possible.
That’s why it’s so important to take care of your child’s baby teeth. Even though they won’t be around forever, they have a vital role to play right now. So be sure proper attention is paid to your child’s oral hygiene: That means avoiding sugar, and remembering to brush and floss every day. And be sure to come in regularly for routine exams, cleanings, and needed care. It’s the best way to keep those little teeth from “going extinct” too soon!

When it comes to our children’s safety, there isn’t much nowadays that isn’t under scrutiny. Whether food, clothing, toys and more, we ask the same question: can it be harmful to children?
That also includes tried and true healthcare practices. One in particular, the routine x-ray, has been an integral part of dental care for nearly a century. As a means for detecting tooth decay much earlier than by sight, it has without a doubt helped save billions of teeth.
But is it safe for children? The reason to ask is because x-rays are an invisible form of electromagnetic radiation that can penetrate human tissue. As with other forms of radiation, elevated or frequent exposure to x-rays could damage tissue and increase the future risk of cancer.
But while there is potential for harm, dentists take great care to never expose patients, especially children, to that level or frequency of radiation. They incorporate a number of safeguards based on a principle followed by all healthcare professionals in regard to x-rays called ALARA, an acronym for “as low as reasonably achievable.” This means dentists and physicians use as low an exposure of x-ray energy as is needed to achieve a reasonable beneficial outcome. In dentistry, that’s identifying and treating tooth decay.
X-ray equipment advances are a good example of ALARA in action. Digital imaging, which has largely replaced film, requires less x-ray radiation for the same results than its older counterpart. Camera equipment has also become more efficient, with modern units containing lower settings for children to ensure the proper amount of exposure.
Dentists are also careful how often they take x-ray images with their patients, only doing so when absolutely necessary. As a result, dental patients by and large experience lower dosages of x-ray radiation in a year than they receive from natural radiation background sources found every day in the environment.
Dentists are committed to using x-ray technology in as safe and beneficial a way as possible. Still, if you have concerns please feel free to discuss it further with your dental provider. Both of you have the same goal—that your children have both healthy mouths and healthy bodies for the rest of their lives.

Although energy and sports drinks have different purposes, they have one thing in common: they often contain added citric and other acids to improve taste and prolong shelf life. Their high acid content can harm tooth enamel.
Although enamel is the strongest substance in the body, acid can dissolve its mineral content. And although saliva neutralizes acid after eating or drinking and helps restore lost minerals to the enamel, it may not be able to keep up if the mouth remains acidic for a prolonged period of time.
That could happen with both beverage types. While energy drinks have higher acid levels than sports drinks, both are high compared with other beverages.
A recent laboratory experiment studied the two beverages’ effect on tooth enamel. The researchers submerged samples of enamel in six different beverage brands (three from each category) for fifteen minutes, and then in artificial saliva for two hours to simulate mouth conditions. They repeated this cycle four times a day for five days.
At the end of the experiment the enamel in the energy drinks lost on average 3.1 % of their structure, while the sports drink samples lost 1.5%. Although energy drinks appeared more destructive, the acid in both beverages caused enamel damage. Although there are other factors to consider in real life, the experiment results do raise concerns about both beverages’ effect on dental health.
You can, however, minimize the potential harm to your enamel from energy or sports drinks. First, try other beverage choices lower in acid; water, for example, is a natural hydrator and neutral in pH. Try to only drink energy or sports beverages at mealtimes when your saliva is most active. And after drinking, rinse your mouth out with water to dilute any remaining acid.
And although it sounds counterintuitive, wait about an hour to brush your teeth after drinking one of these beverages. Your enamel can be in a softened state before saliva can re-mineralize it, so brushing earlier could remove tiny amounts of enamel minerals.
Taking these steps with energy or sports beverages could help you reduce the chances for enamel erosion. Doing so may help you avoid unnecessary damage to your teeth and overall dental health.

After months of wearing braces it's time for the big reveal: your new and improved smile! Your once crooked teeth are now straight and uniform.
But a look in the mirror at your straighter teeth might still reveal something out of place: small chalky-white spots dotting the enamel. These are most likely white spot lesions (WSLs), points on the enamel that have incurred mineral loss. It happens because mouth acid shielded by your braces contacted the teeth at those points for too long.
Most mouth acid is the waste product of bacteria that thrive in dental plaque, a thin film of food particles that can build up on tooth surfaces. High levels of acid are a definite sign that plaque hasn't been removed effectively through brushing and flossing.
But normal hygiene can be difficult while wearing braces: it's not easy to maneuver around brackets and wires to reach every area of tooth surface. Specialized tooth brushes can help, as well as floss threaders that help maneuver floss more easily through the wires. A water irrigator that uses pulsating water to remove plaque between teeth is another option.
However, if in spite of stepped-up hygiene efforts WSLs still develop, we can treat them when we've removed your braces. One way is to help re-mineralize the affected tooth surfaces through over-the-counter or prescription fluoride pastes or gels. It's also possible re-mineralization will occur naturally without external help.
While your teeth are sound, their appearance might be diminished by WSLs. We can improve this by injecting a liquid tooth-colored resin below the enamel surface. After hardening with a curing light, the spot will appear less opaque and more like a normal translucent tooth surface. In extreme cases we may need to consider porcelain veneers to cosmetically improve the tooth appearance.
In the meantime while wearing braces, practice thorough dental hygiene and keep up your regular cleaning visits with your general dentist. If you do notice any unusual white spots around your braces, be sure to see your dentist or orthodontist as soon as possible.
