At your child's latest dental visit, you found out one of their primary (“baby”) teeth has become decayed and in danger of loss. Of course, you may think, it's only a primary tooth — it's going to come out sooner or later.
But a primary tooth lost “sooner” rather than “later” can create long-term negative consequences for your child's dental health. For the sake of the future permanent tooth, the best treatment strategy could be to put forth the effort and expense to save it.
Besides its role in eating and chewing, a primary tooth's most important function is as a “trailblazer” for the permanent tooth developing below it. A primary tooth doesn't normally loosen and let go until the new permanent tooth is ready to erupt. Until then they hold the new tooth's space in the jaw.
But if the primary tooth is lost prematurely, nearby teeth can drift into and crowd the space so that the permanent tooth comes in out of position. This can result in a malocclusion, or poor bite.
Depending on the state of your child's jaw development, it may be advisable to attempt saving the tooth through a filling or, in the case of deep decay, a modified root canal treatment. If the tooth can't be saved, then placing an orthodontic appliance known as a space maintainer might be necessary. Cemented to a tooth next to the empty space, this appliance has a looped band of metal that butts against the tooth on the other side of the gap, and prevents both teeth from drifting into the space.
Intervening for a decayed primary tooth can seem a waste of time and money since it has a limited lifespan to begin with. But for the health of its companion permanent tooth, as well as possibly avoiding orthodontic treatment, it could be well worth it for your child's long-term dental health.

The final emergence of permanent teeth in late adolescence marks the end of a long process beginning in the womb with the formation of our primary or “baby” teeth. Permanent teeth form in a similar way as buds high in the jaw, continuing to grow until the primary teeth ahead of them fall away. The crowns of the new adult teeth eventually break through the gum tissue and emerge (erupt) into view.
At least, that’s normally what should happen; sometimes, though, a tooth may only erupt partially or not at all, a condition known as impaction. The crown remains partially or fully submerged below the gum line, causing the tooth to press against other teeth, potentially damaging them. It can also make periodontal (gum) tissues adjacent to the area more susceptible to disease. Wisdom teeth are especially prone to this kind of impaction, to the extent they’re often surgically removed (extracted) to avoid future problems to adjacent teeth or the bite.
Upper canines (the “eye teeth” normally located directly below the eyes) are also subject to impaction. But because of their highly visible position, extracting them could have an adverse impact on the patient’s smile. In this case, we often attempt instead to expose and ultimately save the tooth.
Before taking any action, however, an orthodontic examination is conducted first to pinpoint the exact position of the impacted tooth and determine how that position might affect moving teeth into a more desired alignment. If we find the impacted canine is in a workable position, the next step is to surgically uncover the tooth from the gum tissue (a minor procedure usually performed by an oral surgeon or periodontist). Once exposed, an orthodontic bracket with a small attached gold chain is bonded to the tooth. The gums are then sutured back into place with the chain exposed and allowed to heal.
At some future point an orthodontist will attach the chain to orthodontic hardware that will pull the impacted tooth into proper position over several months. As a result, the upper canine becomes “un-impacted”; the dangers to surrounding teeth and tissues are also reduced. And, just as important, we can preserve the tooth and with orthodontics achieve an attractive, normal smile.

Children losing their primary (“baby”) teeth is both natural and necessary. So, is it really that much of a concern if they lose one early?
The answer is yes — premature primary tooth loss could have long-term consequences for the permanent teeth as they develop within the jaw before eruption. Primary teeth play a crucial role in this development: as the permanent teeth form and grow the primary teeth serve as placeholders until they’re ready to erupt. A natural process then takes place in which the primary tooth’s roots dissolve (resorb) to allow them to fall out. Once they’re out of the way, the permanent teeth can then erupt.
If, however, they’re lost before the permanent teeth are ready, it leaves a space in the child’s bite. The dynamic mechanism between teeth and the periodontal ligament causes adjacent teeth to move or “drift” into the space. This can crowd out the permanent tooth intended for the space, causing it to come in improperly forming a malocclusion (bad bite), or it may become impacted and remain partially or fully below the surface of the gums.
This poor dental development could lead to extensive orthodontic treatment later in life, which is why we seek to preserve even decayed primary teeth for their entire natural lifespan. If the tooth is lost, however, we need to take action to preserve the space for the permanent tooth and avoid costly treatment later.
This usually calls for a “space maintenance” appliance — a type of orthodontic “retainer” — worn by the child to prevent other teeth from drifting into the space. Designed by your orthodontist, the appliance can also perform a cosmetic and social function by causing the space to appear unnoticeable.
Maintaining that space requires monitoring — especially by an orthodontist — and continued dental hygiene and care both at home and at the dentist’s office. The extra care preserving the space caused by premature tooth loss will help to ensure your child’s dental structure develops properly and their future smile will be an attractive one.

When most people think of orthodontic treatment, they may think of braces worn during the teenage years. But there are some types of malocclusions (bad bites) that may benefit from intervention much earlier than adolescence. A cross-bite is one example.
A cross-bite occurs when the front teeth of the lower arch bite in front of the upper teeth rather than behind them. The condition can have an adverse effect on any of the six front teeth of either arch. This type of malocclusion can develop quite early in childhood.
Orthodontists have developed a two-phase treatment for a cross-bite, with the possibility that the first phase may be all that’s needed. If your child has a cross-bite, your orthodontist may first recommend he or she wear a specially-designed retainer for a few months. The retainer could stop and correct an existing problem before it becomes worse, or it could prevent a deeper problem from developing in the first place. The retainer could also help guide jawbone development during these formative years, even as early as age 7, for children at risk.
Even if this first phase doesn’t fully correct the cross-bite and the second phase (most likely braces or a similar orthodontic device) becomes necessary, it could still help to make the second phase easier and less costly. On the other hand, if orthodontic treatment is postponed until adolescence when the mouth structures are more fully formed it may become quite difficult or even impossible to correct the problems that have developed.
As a result, early intervention for this or similar orthodontic conditions is the most efficient strategy, even when later treatment is necessary. As part of your child’s regular dental care (which should begin ideally around their first birthday), we can advise you on any need for an orthodontic evaluation based on our observations. An orthodontist can then best advise whether waiting until later for treatment is best, or whether intervention now could lessen problems later.

We in dentistry, advise parents to have an orthodontic evaluation some time before your child is 7 years of age. At this time, some of your child's adult teeth have come in and some primary (baby) teeth remain. This is a good time to check for developing problems. Treatment that begins while your child's teeth are coming in is called “interceptive orthodontics.” It provides an opportunity to achieve the best results in orthodontic treatment.
Once this evaluation takes place, it may mean that orthodontic treatment may need to take place in two-stages. A first phase of orthodontic treatment may prevent, intercept or minimize future orthodontic treatment. The first stage may be a process of guiding the growth of the jawbones that support the teeth. This is called “growth modification.” Then when the adult teeth have erupted through the gums, it may be time to do the second and final stage.
If a second phase of treatment is necessary it will probably require braces. These are small metal brackets that are bonded to the teeth. Thin flexible wires are threaded through them, and the wires are designed to push or pull on the teeth to provide a small amount of pressure that makes the teeth slowly reposition themselves within the jawbone. A light and controlled force pulling on a tooth causes new bone and ligament (the fibers that hold teeth in place) to be formed. These are living tissues that are constantly changing and remodeling themselves.
If you wait until your child's permanent (adult) teeth have all come in to start this process, it will be too late to correct some types of orthodontic problems, such as some types of malocclusions (“mal” – bad, “occlusion” – bite). It's better to work together with your child's stages of growth and development in order to have an optimum correction, both in looks and function.
You may be wondering whether a two-stage treatment costs twice as much. In fact, it is likely to be less expensive than a late one-stage treatment would be. Sometimes, the first stage may correct an underlying problem and make further treatment unnecessary. If a second phase is needed, it is likely to be easier and less costly.
