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.

Like the rest of their bodies, children’s teeth and mouth are on a rapid development track. By the time they’re young adults, they will have had two sets of teeth, extensive bone growth and a noticeable change in their features. The natural process is truly amazing.
But dental disease can easily derail their development, with tooth decay the most common problem children encounter. More than at any other time of life, preventive dental care is a top priority.
True preventive care for your child includes the entire mouth, not just the teeth. Our main focus, of course, is to head off tooth decay before it develops, including the application of topical fluoride or sealants when appropriate. But we also monitor bite development and provide protection against sports injuries or other forms of trauma with customized mouth guards.
You also have a part to play in your child’s preventive dental care. It begins when your child’s first teeth begin to emerge in the mouth — the point when you should begin brushing them. You can also reduce the risk of dental disease by providing a nutritious diet that’s high in fresh fruits and vegetables and low in sugar, especially between-meal snacks.
You should also start regular dental visits around their first birthday. This is not only the best time to begin professional care, but your child will also have an easier time at this age becoming comfortable with visiting the dentist than waiting until they’re older.
Taking care of your child’s teeth is a working partnership between you and us: we provide the professional care your child needs to develop properly, while you look to their daily hygiene and nutrition, which is just as important for your child’s healthy development. Through our partnership, we can ensure your child is getting the very best start toward a lifetime of healthy teeth and gums.
As a basic orthodontic appliance, braces are what allows us to move teeth into better positions to improve a person’s bite. In certain cases, though, this treatment application gets a little assistance from Temporary Anchorage Devices (TADs) to improve accuracy and reduce treatment time.
Braces take advantage of our teeth’s natural ability to move. Teeth are held in place within the bone by the periodontal ligament, an elastic tissue that attaches to the teeth with microscopic fibers secured by a hardened substance called cementum. The periodontal ligament is constantly remodeling in response to changes in the mouth. As pressure is placed on a tooth, new bone, ligament and cementum are formed on the “pulling” side of the tooth; on the other side, the bone and ligament dissolve (resorb), allowing the tooth to move in that direction.
Braces allow this natural process to occur with controlled forces applied by thin flexible wires threaded through the small brackets attached to the front of the teeth and then affixed or “anchored” to other teeth. By attaching the teeth to the other teeth by wires running through all the brackets, “anchorage” is created to allow teeth to be moved where the dentist wants them to go. By adjusting the tension on the wires, we can apply light but constant pressure on the “unanchored” teeth to move them into a new desired position.
Teeth we do not want to move are referred to as the anchorage for teeth we do want to move. If, however, the situation calls for more precise isolation of teeth to be moved, TADs can be very useful. TADs are mini-implants imbedded in the bone to serve as anchorage at strategic locations in the mouth. In this way, the group of teeth to be moved receives forces that are applied through the additional anchorage provided by the TADs. That “tension” or “pressure” is applied only to them and not to adjacent teeth that should not move. This increases efficiency for tooth movement and helps reduce the treatment time.
TADs can be placed using local anesthesia and with little discomfort, and are removed when orthodontic treatment is completed. Although the procedure is pretty straightforward, it does require collaboration between orthodontist and surgeon to ensure correct positioning.
In the end, TADs increase our ability to control the forces that move teeth during orthodontic treatment. This lessens discomfort for the patient and helps ensure the end result — a more functional bite and a transformed smile.

Primary (baby) teeth might not last long, but their impact can last a lifetime. Their first set of teeth not only allows young children to eat solid foods, but also guide permanent teeth to form and erupt in the proper position.
Unfortunately, primary teeth aren't immune to tooth decay. If the decay is extensive, the tooth may not last as long as it should. Its absence will increase the chances the permanent teeth won't come in correctly, which could create a poor bite (malocclusion) that's costly to correct.
If a primary tooth is already missing, we can try to prevent a malocclusion by installing a “space appliance.” This keeps nearby teeth from drifting into the empty space intended for the permanent tooth. The best approach, though, is to try to save a primary tooth from premature loss.
We can often do this in much the same way as we would with a permanent tooth — by removing decayed material and filling the prepared space. We can also perform preventive applications like topical fluoride or sealants that strengthen or protect the tooth.
It becomes more complicated, though, if the pulp, the interior of the tooth, becomes decayed. The preferred treatment for this in a permanent adult tooth is a root canal treatment. But with a primary tooth we must also consider the permanent tooth forming below it in the jaw and its proximity to the primary tooth. We need to adapt our treatment for the least likely damage to the permanent tooth.
For example, it may be best to remove as much decayed structure as possible without entering the pulp and then apply an antibacterial agent to the area, a procedure known as an indirect pulp treatment. We might also remove only parts of the pulp, if we determine the rest of the pulp tissue appears healthy. We would then dress the wound and seal the tooth from further infection.
Whatever procedure we use will depend on the extent of decay. As we said before, our number one concern is the permanent tooth beneath the primary. By focusing on the health of both we can help make sure the permanent one comes in the right way.

Overbites, underbites, crossbites—these are just a few of the possible malocclusions (poor bites) you or a family member might be experiencing. But no matter which one, any malocclusion can cause problems.
Besides an unattractive smile, a malocclusion makes it more difficult to chew and to keep the teeth and gums clean of disease-causing bacterial plaque. Thus correcting a malocclusion improves dental health; a more attractive smile is an added bonus.
This art of correction—moving teeth back to the positions where they belong—is the focus of a dental specialty called orthodontics. And, as it has been for several decades, the workhorse for achieving this correction is traditional braces.
Braces are an assembly of metal brackets affixed to the teeth through which the orthodontist laces a metal wire. The wire is anchored in some way (commonly to the back teeth) and then tightened to apply pressure against the teeth. Over time this constant and targeted pressure gradually moves the teeth to their new desired positions.
The reason why this procedure works is because teeth can and do move naturally. Although it may seem like they’re rigidly set within the jawbone, teeth are actually held in place by an elastic tissue network known as the periodontal ligament. The ligament lies between the tooth and bone and keeps the tooth secure through tiny fibers attached to both it and the bone. But the ligament also allows teeth to continually make micro-movements in response to changes in chewing or other environmental factors.
In a sense, braces harness this tooth-moving capability like a sail captures the wind propelling a sailboat. With the constant gentle pressure from the wires regularly adjusted by the orthodontist, the periodontal ligament does the rest. If all goes according to plan, in time the teeth will move to new positions and correct the malocclusion.
In a way, braces are the original “smile makeover”—once crooked teeth can become straight and more visually appealing. More importantly, though, correcting a poor bite improves how the mouth works, especially while eating, and keeping things clean. A straighter smile isn’t just more attractive—it’s healthier.
