Orthodontics can produce an amazing smile transformation. With today’s advanced appliances and techniques even the most difficult malocclusions (bad bites) can be overcome. All of this innovation, however, depends on one basic anatomical fact: though firmly set in the mouth, our teeth can still move.
Teeth are actually held in place by the periodontal ligament, a strong, elastic tissue that attaches to them through tiny collagen fibers on one side of the ligament and to the jawbone with similar fibers on the other side. When pressure is placed against a tooth, the bone on the opposite side of the force begins to dissolve (resorb), allowing the tooth to move. As it moves, new bone is built up behind the tooth, to stabilize it. Orthodontists take advantage of this natural mechanism through orthodontic hardware like braces that applies pressure in the desired direction of movement, while the ligament and bone do the rest.
There is, though, a downside to this process. The teeth, bone and gum tissues can contain a kind of “memory” for the former natural position of the teeth. Over time, the lower front teeth tend to take a gradual migratory movement back towards their original position. Also, as we age the lower front teeth may crowd each other as there is a genetic influence for teeth to move to the midline of the face, causing a pressure that allows the skinny lower front teeth to slip behind each other. As a result of both of these tendencies, corrected teeth may retreat from their new positions.
To stop these tendencies, we use an appliance known as a retainer after braces or other hardware is removed. As the name implies, this appliance “retains” the teeth in their new position. For structural “memory,” the retainer will keep the teeth in their new position until the impulse to return to the old one has faded, about eighteen months. Retainers can also slow or stop the natural genetic influence of movement, but it may mean wearing a retainer for an indefinite period, especially individuals who’ve undergone orthodontic treatment later in life.
The length of time you’ll need to wear a retainer after braces — and what type, whether a removable appliance or one permanently attached — will depend on a number of factors including the type of malocclusion, your individual mouth structure and age. We’ll recommend the best option that ensures the best chance of keeping your teeth in their new position.

As is the case with most celebs today, Beyonce is no stranger to sharing on social media… but she really got our attention with a video she recently posted on instagram. The clip shows the superstar songstress — along with her adorable three-year old daughter Blue Ivy — flossing their teeth! In the background, a vocalist (sounding remarkably like her husband Jay-Z) repeats the phrase “flossin’…flossin’…” as mom and daughter appear to take care of their dental hygiene in time with the beat: https://instagram.com/p/073CF1vw07/?taken-by=beyonce
We’re happy that this clip highlights the importance of helping kids get an early start on good oral hygiene. And, according to authorities like the American Dental Association and the American Academy of Pediatric Dentistry, age 3 is about the right time for kids to begin getting involved in the care of their own teeth.
Of course, parents should start paying attention to their kids’ oral hygiene long before age three. In fact, as soon as baby’s tiny teeth make their first appearance, the teeth and gums can be cleaned with a soft brush or cloth and a smear of fluoride toothpaste, about the size of a grain of rice. Around age 3, kids will develop the ability to spit out toothpaste. That’s when you can increase the amount of toothpaste a little, and start explaining to them how you clean all around the teeth on the top and bottom of the mouth. Depending on your child’s dexterity, age 3 might be a good time to let them have a try at brushing by themselves.
Ready to help your kids take the first steps to a lifetime of good dental checkups? Place a pea-sized dab of fluoride toothpaste on a soft-bristled brush, and gently guide them as they clean in front, in back, on all surfaces of each tooth. At first, it’s a good idea to take turns brushing. That way, you can be sure they’re learning the right techniques and keeping their teeth plaque-free, while making the experience challenging and fun.
Most kids will need parental supervision and help with brushing until around age 6. As they develop better hand-eye coordination and the ability to follow through with the cleaning regimen, they can be left on their own more. But even the best may need some “brushing up” on their tooth-cleaning techniques from time to time.
What about flossing? While it’s an essential part of good oral hygiene, it does take a little more dexterity to do it properly. Flossing the gaps between teeth should be started when the teeth begin growing close to one another. Depending on how a child’s teeth are spaced, perhaps only the back ones will need to be flossed at first. Even after they learn to brush, kids may still need help flossing — but a floss holder (like the one Beyonce is using in the clip) can make the job a lot easier.
