Each year some 4 million teens and pre-teens have their teeth straightened with braces or clear aligners. But there's another facet of bite correction that can take place much earlier in a child's life—and which might reduce or eliminate orthodontic treatment later.
Techniques known as interceptive orthodontics do exactly what the name implies—get ahead of bite problems before they fully develop. Many of these treatments attempt to influence jaw development, a prime factor in many bite problems. Although braces may be a part of interceptive treatment, it often includes other devices.
Here are 3 examples of interventional treatments that can stop a growing bite problem in its tracks.
Palatal expanders. Sometimes, an upper jaw may be growing too narrowly. As a result, incoming permanent teeth don't have enough space and can erupt out of position. A palatal expander device, usually installed around age 7 against the roof of the mouth, puts pressure on the side teeth to "push" the jaw outward. This widens a gap in the center of the pallet, which then fills with new bone. By the time the gap closes in early adolescence, the jaw has gained width and more room for incoming teeth.
Herbst appliances. Supporting muscles and bones can pressure the upper jaw to grow too far forward, which in turn creates an overbite where the upper teeth severely overlap the lower. An orthodontist may attach a Herbst appliance, a device consisting of two metal hinges, to the upper and lower jaws toward the back of the mouth. The hinge action forces the jaw muscles and bones to move the lower jaw forward as it grows, resulting in a better relationship with the upper jaw.
Space maintainers. Not all interceptive techniques involve intricate appliances—a simple looped wire could prevent a later bite problem. Because primary (baby) teeth hold the spaces for future permanent teeth, losing one too early could create an empty space into which surrounding teeth can drift. This, then, reduces the space available for the incoming tooth, causing it to erupt out of position. Placing a looped wire called a space maintainer into the space prevents the teeth around the gap from moving into it.

Dental implants are often the ideal choice to replace missing teeth. Unfortunately, "ideal" and "affordable" don't always align simultaneously for people. Even if implants are right for you, you may have to put them off to a more financially appropriate season.
In the meantime, though, you're still missing teeth—and perhaps some of them are right square in the middle of your smile. What can you do now, even if temporarily?
The solution might be a flexible removable partial denture (RPD). These newer types of RPD fit somewhere between the lightweight "flipper" and the more traditional rigid plastic appliances often made for permanent use. The flexible RPD is made of nylon plastic (technically known as a super-polyamide), which although lightweight, is highly durable.
Super-polyamides change their shape under high heat, a characteristic dental technicians take advantage of by injection molding heated material into flexible denture bases, to which they then attach the replacement teeth. Like other RPDs, a flexible RPD is custom-designed for the individual patient to match their jaw contours, as well as the types and locations of their missing teeth.
Flexible RPDs also differ from other RPD types in how they stay in place. While the more rigid RPD depends on metal clasps that grip to some of the remaining natural teeth, a flexible RPD uses finger-like extensions of the nylon material to fit around teeth near the gum line where they're difficult to see. As such, the flexible RPD is both comfortable and securely held in place.
A flexible RPD, like their counterparts, does require regular maintenance. Any RPD can accumulate dental plaque, a thin biofilm buildup on teeth that causes dental disease. For this reason, wearers should regularly remove their RPD and clean it thoroughly with an antibacterial soap (never toothpaste). All RPDs should also be removed at night to limit bacterial growth.
With a little care, a flexible RPD could last for several years. It could be just the solution to buy you time while you're waiting to obtain dental implants.

Just a century ago a heavily decayed tooth was most likely a goner, but that all changed in the early 1900s when various treatments finally coalesced into what we now call root canal therapy. The odds have now flip-flopped—you're more likely to preserve a decayed tooth than to lose it.
By decay, we're not referring only to cavities in a tooth's enamel or outer dentin. That's just the start—decay can quickly spread deeper into the dentin close to the pulp, the central portion of a tooth containing bundles of nerves and blood vessels. It can then move into the tooth's pulp chamber, causing the pulp to die and producing infection that will eventually infect the surrounding supporting bone.
Root canal treatments are often a lifeline to a tooth in this perilous condition. After numbing the tooth and surrounding tissues with local anesthesia, we start the procedure by drilling a tiny hole to access the central pulp and root canals. We then use specialized tools to remove all of the infected tissue within these interior spaces.
After thoroughly disinfecting the tooth of any decay, we shape up the root canals for filling. We then inject a rubbery substance known as gutta percha and completely fill the tooth's resulting empty spaces. This filling helps to prevent a recurrence of infection within the tooth.
Once we've filled the tooth, we seal off the access hole to complete the procedure. You may experience a few days of mild discomfort, but it's usually manageable with over-the-counter pain relievers. Later, we'll cement a crown over the tooth: This provides additional protection against infection, as well as adds support to the tooth structure.
One more thing! You may have encountered the notion that undergoing a root canal is painful. We're here to dispel that once and for all—dentists take great care to ensure the tooth and the area around it are completely dead to pain. In fact, if you were experiencing a toothache beforehand, a root canal will alleviate the pain.
To get the best treatment outcome for tooth decay, it's important to uncover it as soon as possible. The earlier we begin treatment, the more likely we can bring your tooth back to good health.

Dental accidents do happen, especially among active tweens and teens. When it does, saving traumatized teeth becomes priority one. It's especially important for these younger age groups whose developing dental structures depend on having a jaw-full of permanent teeth.
But because their permanent teeth are still developing, it's often more difficult to treat them than fully grown teeth. That's because the standard treatment—root canal therapy—isn't advisable for an immature tooth.
During a root canal, a dentist removes the diseased or traumatized tissues inside the pulp and root canals, and subsequently fills the empty spaces to prevent further infection. It's safe to do this, even though we remove much of the pulp's nerve and blood vessel tissue in the process, because these tissues aren't as critical to a fully matured tooth.
But these tissues within the pulp are quite important to a tooth still under development—they help the tooth form strong roots and a normal layer of dentin. Their absence could stunt further growth and lead to future problems with the tooth.
For that and other reasons, we avoid a traditional root canal therapy in immature teeth as much as possible, opting instead for techniques that leave the pulp as intact as possible. The approach we use depends on the condition of the pulp after an injury.
For injuries where the pulp remains unexposed and undamaged within the dentin layer, we might remove as much of the damaged tooth structure as possible, while leaving a small portion of dentin around the pulp. We would then apply an antibacterial agent to this remaining dentin to protect the pulp from infection, and fill the tooth.
If an injury exposes the pulp and partially damages it, we might fully remove any damaged tissues and apply a material to the exposed pulp to stimulate new dentin growth. If successful, the dentin around the pulp will regenerate to restore protective coverage.
The methods we use will depend on the degree of damage to the tooth and pulp tissues, a traditional root canal serving as a last resort. Our aim is to not only save the tooth now, but also give it the best chance for long-term survival.

As you get older, you may find yourself regretting things from your youth: getting that tattoo with your (ex) lover's name; giving up on piano lessons; or, not investing in that fledgling, little company called Facebook. Here's another thing you might regret: Not having your crooked smile straightened when you were a teenager.
We can't advise you on your other life issues, but we can on the latter—stop regretting your less than perfect smile and take action, because you still can! Even several years removed from adolescence you can still straighten your smile. Age makes no difference: as long as you and your mouth are relatively healthy, you can undergo bite correction even late in life. And, you'll be joining the current 1 in 5 orthodontic patients who are adults.
Straightening your teeth—what some call "the original smile makeover"—can radically transform your appearance and boost your self-confidence. But orthodontic treatment could also boost your dental health: Misaligned teeth are harder to keep clean, so realigning them reduces your risk for dental disease.
You're sold…but, one thing may still hold you back: you're not crazy about how you, a grown adult, might look in braces. You may, however, have a more attractive option with clear aligners.
Clear aligners are a series of clear plastic mouth trays computer-generated from measurements of your teeth and jaws. During treatment, you'll wear each tray for about two weeks before changing to the next one in the sequence. The dimensions on each tray vary slightly so that they move your teeth gradually, just like braces.
Because they're nearly invisible, they don't stand out like braces. And unlike braces, you can also remove them for meals, oral hygiene, or special occasions (although to be effective, you'll need to wear them most of the time).
If you'd like to know more, visit your orthodontist for a complete exam and consultation. After reviewing your options, you may decide to bid adieu to at least one life regret—and get the perfect smile you've always wanted.
