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.

Today’s healthcare patients are asking questions. They want to know the “why” behind the “what” that their care providers are recommending for their health.
There’s a similar trend in dentistry — and it’s one we dentists encourage. We want you to know the “why” behind your treatment options — because you’re as much a participant in your own dental health as we are. The more informed you are, the better equipped you’ll be to make decisions to maintain or improve your health and the appearance of your smile.
As your dental care partner, it’s also essential we help you develop a long-term care plan based on your needs. There are aspects of dental care that are routine: daily brushing and flossing, an oral-friendly diet, and regular dental cleanings and checkups to assess your oral health. But we also need to think strategically, especially if you have risk factors that could impact your future dental health.
To do this we follow a four-step dental care cycle. In Step 1 we identify all the potential risk factors you personally face. These include your potential for dental disease, which could lead to bone and tooth loss, and the state of your bite and jaw structure that could complicate future health. We’ll also take into account any factors that could now or eventually affect your smile appearance.
Once we’ve identified these various factors, we’ll then assess their possible impact on your health in Step 2, not just what may be happening now but what potentially could happen in the future. From there we move to Step 3: treating any current issues and initiating preventive measures to protect your future health.
In Step 4 we’ll monitor and maintain the level of health we’ve been able to reach with the preceding steps. We’ll continue in this stage until we detect an emerging issue, in which we’ll then repeat our cycle of care.
Maintaining this continuum will help reduce the chances of an unpleasant surprise in your dental health. We’ll be in a better position to see issues coming and help reduce their impact now so you can continue to have a healthy mouth and an attractive smile.
