AnAssortmentofOrthodonticToolshelpsusSolveComplexBiteProblems

There are an assortment of techniques and treatments in an orthodontist's toolkit, braces being the most common and best known. Of course, there wouldn't be any tools at all if teeth couldn't move naturally.

Teeth aren't directly connected to the jawbone. An elastic tissue called the periodontal ligament lies between each one, with tiny fibers attaching to the tooth on one side and to the bone on the other. The ligament's elasticity and other qualities allow micro-movements of the teeth as we bite.

The ligament can also adapt to changes in the mouth and teeth by allowing the teeth to move to different positions. That's the basic concept behind braces: we thread a thin wire through brackets attached to the teeth, which we then attach to anchor points (usually back teeth not intended to move) and apply tension to it. Gradually over time, the target teeth move.

But what if your malocclusion (poor bite) is more complicated or the back teeth can't supply enough anchorage for moving the intended teeth? That's where we take advantage of other sources of anchorage.

One such source is the patient's skull, which we can make use of through special headgear worn a few hours a day. The device consists of a strap under tension that runs around the back of the head or neck to a wire housing attached to brackets on the target teeth. If you want to “pull” the teeth forward, the strap would come over the chin, forehead or a combination of both.

We may sometimes want to isolate some teeth to move without moving nearby teeth, such as moving front teeth backward to close a space without affecting teeth further to the rear. We can create a separate anchor point in the jaw with a TAD or temporary anchorage device.

TADs are tiny screws made of stainless steel inserted temporarily into the bone. We loop an elastic band over the TAD on one end and to a bracket or tension wire attached to the target teeth on the other. When we've achieved the teeth's new position we can easily remove the TAD from the bone.

These various tools make it possible to correct difficult or complex malocclusions. They may not always look attractive, but they'll help ensure the final result is.

WhyaBondedRetainerMightbeaBetterChoiceAfterBraces

A lot of time and effort goes into straightening your smile. But there’s a possibility it might not stay that way—and all that hard work could be lost. The same natural mechanism that enables your teeth to move with braces could cause them to revert to their old, undesirable positions.

So for a little while (or longer for some people) you’ll need to wear a retainer, an appliance designed to keep or “retain” your teeth where they are now. And while the removable type is perhaps the best known, there’s at least one other choice you might want to consider: a bonded retainer.

Just as its name implies, this retainer consists of a thin metal wire bonded to the back of the teeth with a composite material. Unlike the removable appliance, a bonded retainer is fixed and can only be removed by an orthodontist.

Bonded retainers have several advantages. Perhaps the most important one is cosmetic—unlike the removable version, others can’t see a bonded retainer since it’s hidden behind the teeth. There’s also no keeping up with it—or losing it—since it’s fixed in place, which might be helpful with some younger patients who need reminding about keeping their retainer in their mouth.

There are, however, a few disadvantages. It’s much harder to floss with a bonded retainer, which could increase the risks of dental disease. It’s also possible for it to break, in which case it will need to be repaired by an orthodontist and as soon as possible. Without it in place for any length of time the teeth could move out of alignment.

If you or a family member is about to have braces removed, you’ll soon need to make a decision on which retainer to use. We’ll discuss these options with you and help you choose the one—removable or bonded—that’s right for you.

BaseballsFranciscoLindorShinesasMrSmile

At the first-ever Players Weekend in August 2017, Major League Baseball players wore jerseys with their nicknames on the back. One player — Cleveland Indians shortstop, Francisco Lindor — picked the perfect moniker to express his cheerful, fun-loving nature: “Mr. Smile.” And Lindor gave fans plenty to smile about when he belted a 2-run homer into the stands while wearing his new jersey!

Lindor has explained that he believes smiling is an important part of connecting with fans and teammates alike: “I’ve never been a fan of the guy that makes a great play and then acts like he’s done it 10,000 times — smile, man! We’ve got to enjoy the game.”

We think Lindor is right: Smiling is a great way to generate good will. And it feels great too… as long as you have a smile that’s healthy, and that looks as good as you want it to. But what if you don’t? Here are some things we can do at the dental office to help you enjoy smiling again:

Routine Professional Cleanings & Exams. This is a great place to start on the road toward a healthy, beautiful smile. Even if you are conscientious about brushing and flossing at home, you won’t be able to remove all of the disease-causing dental plaque that can hide beneath the gum line, especially if it has hardened into tartar, but we can do it easily in the office. Then, after a thorough dental exam, we can identify any problems that may be affecting your ability to smile freely, such as tooth decay, gum disease, or cosmetic dental issues.

Cosmetic Dental Treatments. If your oral health is good but your smile is not as bright as you’d like it to be, we can discuss a number of cosmetic dental treatments that can help. These range from conservative procedures such as professional teeth whitening and bonding to more dramatic procedures like porcelain veneers or crowns.

Tooth Replacement. Many people hide their smiles because they are embarrassed by a gap from a missing tooth. That’s a shame, because there are several excellent tooth-replacement options in a variety of price ranges. These include partial and full dentures, bridgework, and dental implants. So don’t let a missing tooth stop you from being Mr. (or Ms.) Smile!

If you’d like more information about oral health or cosmetic dentistry, please contact us or schedule an appointment for a consultation. You can also learn more by reading the Dear Doctor magazine articles “Beautiful Smiles by Design” and “The Impact of a Smile Makeover.”

TheRiskforGumDiseaseIncreasesWhileWearingBraces

Your child has had braces for a few months and making good progress with correcting a poor bite (malocclusion), but you’ve also noticed something else: his gums are becoming red and swollen.

These are symptoms of gingivitis, a periodontal (gum) disease. It’s an infection that arises when plaque, a thin film of bacteria and food particles, isn’t adequately removed from teeth with daily brushing and flossing. The braces increase the risk for gingivitis.

This is because the hardware — metal or plastic brackets cemented to the teeth and joined together by metal bands — makes it more difficult to reach many areas of the teeth with a brush or floss string. The plaque left behind can trigger an infection that causes inflammation (swelling) and bleeding.

To exacerbate the situation, gums don’t always take well to braces and can react by overgrowing. Wearing braces may also coincide with a teenager’s surge in hormones that can accelerate the infection. Untreated, gingivitis can develop into advanced stages of disease that may eventually cause tooth loss. The effect is also heightened as we’re orthodontically putting stress on teeth to move them.

You can stay ahead of gingivitis through extra diligence with daily hygiene, especially taking a little more time to adequately get to all tooth surfaces with your brush and floss. It may also help to switch to a motorized brush or one designed to work around braces. You can make flossing easier by using special threaders to get around the wires or a water flosser that removes plaque with a pulsating water stream.

And don’t forget regular dental visits while wearing braces: we can monitor and treat overgrowth, perform thorough dental cleanings and treat occurrences of gingivitis. In some cases you may need to visit a periodontist, a specialist in gums and supporting teeth structures, for more advanced treatment. And if the disease becomes extensive, the braces may need to be removed temporarily to treat the gums and allow them to heal.

Orthodontic treatment is important for not only creating a new smile but also improving your teeth’s function. Keeping a close eye out for gum disease will make sure it doesn’t sidetrack your efforts in gaining straighter teeth.

CorrectaCross-BitebyWideningtheUpperJawwithanExpander

A poor bite (malocclusion) could be more than simply teeth out of alignment. There could be complex causes for the malocclusion, possibly involving the facial bone structure.

An example of this is the development of a cross-bite due to problems with the upper jaw and palate (the roof of the mouth), jointly called the maxilla. The maxilla is in fact formed by two bones fused together in the center of the palate in what's called the midline suture. The suture doesn't completely fuse until after puberty.

Sometimes a maxilla's development doesn't follow a normal track. The upper jaw doesn't widen as it should, which leads to the cross-bite where the upper back teeth abnormally bite inside the lower teeth. The upper front teeth continue to bite normally in front of the lower front teeth. This also can have profound influence on breathing, causing sleep apnea.

We can correct this by using an orthodontic appliance called a palatal expander before the midline suture fuses. The expander gradually widens the upper jaw to its normal width and thus eliminates the cross-bite.

Positioned at the roof of the mouth, the expander has metal arms that extend from a central hinge to exert pressure on the inside of the upper teeth. The patient or a caregiver uses a small key to turn a mechanism that extends the arms toward the teeth a tiny amount each day. This gradually widens the jaw, while at the same time stimulating bone growth at the midline suture. Eventually the gap fills with bone to solidify the new width as the suture fuses.

It's important to undertake this treatment before fusion. If you wait until after puberty, you will need to separate the bones first to attempt it. The overall impact and cost is much less if you act promptly in the early years.

Palatal expansion may not be the right treatment in every case, so we'll need to perform a thorough orthodontic exam first. If, however, we do determine it can help, using an expander can improve function, correct future breathing problems and make possible a more attractive future smile.

If you would like more information on orthodontic treatment options, please contact us or schedule an appointment for a consultation. You can also learn more about this topic by reading the Dear Doctor magazine article “Palatal Expanders: Orthodontics is more than just Moving Teeth.”
