In many ways, the teenage years are the best time to have orthodontic treatment. It’s a good time emotionally because your teen is likely to have friends who also wear braces; orthodontic treatment becomes a rite of passage they can go through together. It’s also advantageous in a physical sense because all 20 baby teeth have come out, and most of the 32 adult teeth (except the 4 wisdom teeth) have emerged. At the same time, especially with younger teens, jaw growth is not yet complete — allowing orthodontists to harness the growing body’s natural adaptability. We can use a variety of appliances to do that — some of which weren’t around a generation ago!
In many cases, traditional metal braces are still the best way to achieve the desired results. However, these are not the “train tracks” of old. Braces are smaller and lighter, with brackets that are cemented to the front surfaces of teeth rather than to bands that encircle the entire tooth (except in the very back). Braces can be made much less noticeable by using ceramic brackets that are clear or tooth-colored; however, ceramic brackets are easier to break than metal. An even stealthier way to undergo orthodontic treatment is with clear aligners. These removable clear plastic “trays” are custom made with the help of computer software that divides the treatment process into two-week stages. After each two-week period, the tray is changed and the next stage of movement takes place until the teeth are in correct alignment. The Invisalign system has two modifications especially for teens: “eruption tabs” that hold space open for emerging molars, and “compliance indicators” that can tell parents and orthodontists if the teen is keeping the trays in for the prescribed amount of time. We’d be happy to discuss whether clear aligners would be an option for your child.
Keeping It Clean
No matter which type of appliance is used, oral hygiene becomes even more important during orthodontic treatment. Wearing braces presents special challenges in terms of keeping teeth clean; however, it’s extremely important to do an effective job every day so that gums do not become inflamed and cavities do not develop. It’s far easier to clean teeth with clear aligners, which can be removed, but the aligners themselves can build up bacteria, leading to the same types of oral health issues if they are not cleaned each day.
Making It Count
Another way in which orthodontic treatment will not vary regardless of the type of appliance chosen is the necessity of a retention phase. Everyone who has their teeth straightened (and this goes for adults and younger kids, too) must wear a retainer to hold the teeth in their new and improved alignment while new bone grows around them. Yes, braces are easier to wear than they used to be… but no one wants to wear them twice!

In real life he was a hard-charging basketball player through high school and college. In TV and the movies, he has gone head-to-head with serial killers, assorted bad guys… even mysterious paranormal forces. So would you believe that David Duchovny, who played Agent Fox Mulder in The X-Files and starred in countless other large and small-screen productions, lost his front teeth… in an elevator accident?
“I was running for the elevator at my high school when the door shut on my arm,” he explained. “The next thing I knew, I was waking up in the hospital. I had fainted, fallen on my face, and knocked out my two front teeth.” Looking at Duchovny now, you’d never know his front teeth weren’t natural. But that’s not “movie magic” — it’s the art and science of modern dentistry.
How do dentists go about replacing lost teeth with natural-looking prosthetics? Today, there are two widely used tooth replacement procedures: dental implants and bridgework. When a natural tooth can’t be saved — due to advanced decay, periodontal disease, or an accident like Duchovny’s — these methods offer good looking, fully functional replacements. So what’s the difference between the two? Essentially, it’s a matter of how the replacement teeth are supported.
With state-of-the-art dental implants, support for the replacement tooth (or teeth) comes from small titanium inserts, which are implanted directly into the bone of the jaw. In time these become fused with the bone itself, providing a solid anchorage. What’s more, they actually help prevent the bone loss that naturally occurs after tooth loss. The crowns — lifelike replacements for the visible part of the tooth — are securely attached to the implants via special connectors called abutments.
In traditional bridgework, the existing natural teeth on either side of a gap are used to support the replacement crowns that “bridge” the gap. Here’s how it works: A one-piece unit is custom-fabricated, consisting of prosthetic crowns to replace missing teeth, plus caps to cover the adjacent (abutment) teeth on each side. Those abutment teeth must be shaped so the caps can fit over them; this is done by carefully removing some of the outer tooth material. Then the whole bridge unit is securely cemented in place.
While both systems have been used successfully for decades, bridgework is now being gradually supplanted by implants. That’s because dental implants don’t have any negative impact on nearby healthy teeth, while bridgework requires that abutment teeth be shaped for crowns, and puts additional stresses on them. Dental implants also generally last far longer than bridges — the rest of your life, if given proper care. However, they are initially more expensive (though they may prove more economical in the long run), and not everyone is a candidate for the minor surgery they require.

People mainly identify orthodontics with braces. But while they’re a major part of it, braces aren’t the only way this important dental specialty can make a difference in a person’s bite.
For example, orthodontics can help guide the development of a younger patient’s facial structure that could head off future upper teeth misalignment. The area of focus is the upper jaw and palate (the roof of the mouth) that jointly make up a structure called the maxilla. The maxilla is actually formed by two bones fused together in the center of the palate along what is known as the midline suture running from front to back in the mouth.
The two bones remain separated until puberty, which helps accommodate rapid structural growth during childhood. But problems can arise if the upper jaw is too narrow, causing a “cross-bite” where the lower back teeth bite abnormally outside the upper ones. This can crowd upper permanent teeth and cause them to erupt improperly.
Using a technique called palatal expansion we can correct this abnormality if we act before the maxillary bones fuse. The technique employs a custom-made appliance called a palatal expander that attaches to the posterior teeth of the upper arch. Expanders have two halves joined by a small screw device to increase tension against the teeth to widen the jaw. A parent or the patient (if old enough) increases the tension by using a special key to turn the adjustment screw a tiny amount each day. This may cause minor discomfort that normally eases in a few minutes.
The patient wears the device until the jaw expands to the desired width and then allows the bones to stabilize in the new position. This can sometimes create a small gap between the upper front teeth, but it often closes on its own or it may require braces to close it.
While palatal expanders are not for every case, they can help normalize development and improve the bite, and thus preclude more extensive orthodontic treatment later. But time is of the essence: after the maxilla has fused, surgery will be necessary to separate them and widen the palate. It’s important then not to delay if your child could benefit from this effective treatment.
