Have you heard about interceptive orthodontics? This type of early intervention could benefit perhaps 10â??20% of children who need orthodontic treatment, making a positive impact on tooth and jaw development, facial symmetry, and overall self esteem. In case you’re not familiar with it, here are the answers to some common questions about interceptive orthodontic treatment.
Q: What’s the difference between interceptive orthodontics and regular orthodontics?
A: Standard orthodontic treatment typically involves moving teeth into better positions (usually with braces or aligners), and can be done at any age. Interceptive orthodontics uses a variety of techniques to influence the growth and development of teeth and jaws, with the aim of improving their function and appearance. Because it works with the body’s natural growth processes, interceptive treatment is most effective before the onset of puberty (around age 10-14), when growth begins to stop. It is generally not appropriate for adults.
Q: What are the advantages of early treatment with interceptive orthodontics?
A: When it’s done at the right time, interceptive treatment offers results that would be difficult or impossible to achieve at an older age without using more complex or invasive methods — for example, tooth extraction or jaw surgery. That’s why the American Association of Orthodontists, among other professional organizations, recommends that all kids have their first orthodontic screening at age 7.
Q: What are some common issues that can be treated with interceptive orthodontics?
A: One is crowding, where there is not enough room in the jaw to accommodate all the permanent teeth with proper spacing in between. A palatal expander can be used to create more room in the jaw and avoid the need for tooth extraction. Another is a situation where the top and bottom jaws don’t develop at the same rate, resulting in a serious malocclusion (bad bite). A number of special appliances may be used to promote or restrict jaw growth, which can help resolve these problems.
Q: How long does interceptive orthodontic treatment take?
A: Depending on what’s needed, a child might wear a device like a palatal expander or another type of appliance for 6-12 months, followed by a retainer for a period of time. Or, a space maintainer may be left in place for a period of months to hold a place for a permanent tooth to erupt (emerge from the gums). Interceptive treatment ends when a child’s jaw stops growing.
Q: Will braces still be needed after interceptive treatment?
A: Often, but not always, the answer is yes. However, interceptive treatment may shorten the period of time where braces need to be worn, and can help prevent many problems later on.

While lasers still seem like science fiction, they’ve been used commercially (and medically) for decades. But there’s still room for growth in practical applications with this developing technology. One promising area is in the treatment of periodontal (gum) disease.
Gum disease is a bacterial infection triggered by plaque, a thin film of bacteria and food particles caused by inadequate oral hygiene. The disease is highly destructive and can eventually lead to both tooth and bone loss. Treatment procedures vary widely, but they all have the same goal: remove the offending plaque and calculus (tartar) from tooth and gum surfaces. Without plaque the infection subsides and the gums can heal.
For decades now, dentists have removed plaque and calculus manually with special hand instruments or ultrasonic equipment. If the disease has advanced below the gum line or formed deep voids filled with infection called periodontal pockets, the dentist may also employ surgical techniques to access the infected areas.
While all these techniques have a long track record for effectiveness, they can cause the inadvertent destruction of healthy tissue, as well as create discomfort for some patients afterward. This is where a new protocol called Laser Assisted New Attachment Procedure (LANAP®) may be able to make a difference in the future.
With the LANAP® protocol, surgeons direct a laser beam of light through a fiber optic the width of three human hairs onto diseased tissue. The particular color of light interacts with the tissue, which contains the darkly-pigmented bacteria causing the disease, and “vaporizes” it. The beam, however, passes harmlessly through lighter-pigmented healthy tissue; as a result diseased tissue is eradicated with little to no harm to adjacent healthy tissue.
With these capabilities, trained dentists using LANAP® for gum disease treatment might be able to achieve conventional results with less tissue removal and bleeding, less discomfort for patients, and less tissue shrinkage than traditional procedures — and without scalpels or sutures. And some post-surgical studies have indicated LANAP® might also encourage gum tissue regeneration in the months following.
LANAP®, however, is still developing and requires further research. Thus far, though, the results have been encouraging. As laser technology advances, it’s quite possible tomorrow’s patient may experience less discomfort and more effective healing with their gum disease treatment.

Over the last century and a half millions of people have had a tooth cavity filled with “silver” amalgam. Perhaps you’re one of them. The use of this effective and durable filling has declined in recent years, but only because of the development of more attractive tooth-colored materials.
At the same time there’s another issue that’s been brewing in recent years about this otherwise dependable metal alloy: the inclusion of mercury in amalgam, about half of its starting mixture. Various studies have shown mercury exposure can have a cumulative toxic effect on humans. As a result, you may already be heeding warnings to limit certain seafood in your diet.
So, should you be equally concerned about amalgam fillings — even going so far as to have any existing ones removed?
Before taking such a drastic step, let’s look at the facts. To begin with, not all forms of mercury are equally toxic. The form causing the most concern is called methylmercury, a compound formed when mercury released in the environment combines with organic molecules. This is the form certain large fish like salmon and tuna ingest, which we then ingest when we eat them. Methylmercury can accumulate in the body’s tissues where at high levels it can damage various organ systems.
Dental amalgam, on the other hand, uses elemental mercury. Dentists take it in liquid form and mix it with a powder of other metals like silver, tin and copper to create a pliable paste. After it’s placed in a prepared cavity, the amalgam hardens into a compound in which the mercury interlaces with the other metals and becomes “trapped.”
Although over time the filling may emit trace amounts of mercury vapor, it’s well below harmful levels. You’re more likely to encounter “un-trapped” mercury in your diet than from a dental filling. And scores of studies over amalgam’s 150-year history have produced no demonstrable ill effects due to mercury.
Although it now competes with more attractive materials, amalgam still fills (no pun intended) a necessary role. Dentists frequently use amalgam in less visible back teeth, which encounter higher chewing pressures than front teeth. So, if you already have an amalgam filling or we recommend one to you, relax — you’re really in no danger of mercury poisoning.
