After months of wearing braces, the big day has arrived — they’re finally off! Your teeth have been realigned and your smile is dazzling. You’re finished with orthodontic treatment, right?
Not quite — because if you want to keep your new smile you have one more treatment phase to go — wearing a retainer. Without this phase there’s a distinct possibility you could lose all the time, effort and expense of braces because your teeth could revert to their previous position.
To understand why, we have to consider how teeth can move in the first place. Although it may seem like your teeth are rigidly fastened to the jawbone, they’re actually held in place by the periodontal ligament, a strong, elastic gum tissue that lies between the teeth and the bone. Tiny fibers from the ligament attach to the teeth on one side and to the bone in a similar manner on the other side.
When pressure is applied to the tooth as happens with braces, the bone around the side of the tooth in the direction of the force will begin to dissolve (resorb), allowing the tooth to move in that direction. New bone will then build up on the other side to stabilize the tooth. Once the pressure is removed (when we take the braces off), there’s a tendency for the teeth, bone and gums to “remember” the old position and try to revert back.
The answer is a removable mouth appliance known as a retainer. Custom-designed to fit the teeth’s new position, the retainer helps hold the teeth in place until the bone completely sets around them. In the beginning, you may need to wear the retainer around the clock and then later only at night while you sleep. While you may only need to wear it for a few months (especially if you’re an adolescent or young adult) some patients may need to wear some form of retainer indefinitely. Your orthodontist will advise you how long depending on your individual situation.
While retainers may seem like an inconvenience, they’re extremely important for keeping or “retaining” the teeth in their new and better position. Following through on this important phase of treatment will help ensure you’ll keep your new smile for a long time to come.

Orthodontists are able to achieve attractive results with traditional braces moving several teeth into a better position. In a way, braces are the original “smile makeover.”
But orthodontic treatment can also be useful if only a few teeth (like the two upper front teeth) need to be moved slightly. A treatment known as minor tooth movement takes only a few months as opposed to years for traditional multiple teeth movement, and with removable appliances that may use small springs or elastics to place gentle pressure on teeth to move them.
So, what constitutes a minor tooth movement scenario? As with any dental condition, the first step is a complete dental examination, particularly the bite. We also need to determine if enough room exists to close any space without compromising the bite with the opposing teeth, and if the teeth and their roots are in a good position to allow minor movement — otherwise, more extensive treatment may be called for. The surrounding gum tissues and bone also need to be healthy and disease-free, especially in adults.
We may also need to look more closely at the actual cause for a front tooth gap. If the gap is the result of the tongue habitually pressing against the back of the teeth and pushing them forward, it may then be difficult or impossible to close the gap with minor tooth movement techniques. The cause may also originate from the frenum (a thin, muscular tissue that rises up from between the upper front teeth toward the lip) if it has extended too far between the teeth. In this case we may first need to surgically remove some of the frenum tissue before attempting orthodontics or the teeth may gradually move back apart after closing the gap.
Although minor tooth movement normally doesn’t take as long as braces, it may still require several months. And just like with braces, you will need to wear a retainer for several months afterward until the bone stabilizes around the new position. Still, minor tooth movement could have a major impact on your smile.
