AnchorsMakealltheDifferenceinSuccessfulOrthodonticTreatment

Orthodontics shares a principle with the classic tug of war game: if you want things to move in the right direction you need a good anchor. Anchors help braces and other appliances apply constant pressure to misaligned teeth in the direction they need to go to correct a malocclusion (poor bite).

Orthodontic treatments work in cooperation with an existing oral mechanism that already moves teeth naturally in response to biting forces or other environmental factors. The key to this mechanism is an elastic tissue known as the periodontal ligament that lies between the tooth and the bone. Besides holding teeth in place through tiny attached fibers, the ligament also allows the teeth to move in tiny increments.

Braces’ wires laced through brackets affixed to the teeth exert pressure on them in the desired direction of movement –the periodontal ligament and other structures do the rest. To maintain that pressure we need to attach them to an “anchor”—in basic malocclusions that’s usually the back molar teeth.

But not all malocclusions are that simple. Some may require moving only certain teeth while not moving their neighbors. Younger patients’ jaws and facial structures still under development may also need to be considered during orthodontic treatment. That’s why orthodontists have other anchorage methods to address these possible complications.

One example of an alternate anchorage is a headgear appliance that actually uses the patient’s skull as the anchor. The headgear consists of a strap running around the back of the head and attached in front to orthodontic brackets (usually on molar teeth). The pressure it exerts can trigger tooth movement, but it can also help influence jaw development if an upper or lower jaw is growing too far forward or back.

Another useful anchorage method is a tiny metal screw called a temporary anchorage device (TAD) that is implanted into the jawbone above the teeth through the gums. Orthodontists then attach elastic bands between implanted TADs and specific braces’ brackets or wires to exert pressure on certain teeth but not others with pinpoint accuracy. After treatment the TADs can be easily removed.

Using these and other appliances allows orthodontists to customize treatment to an individual patient’s particular malocclusion. With the right anchor, even the most complex bite problem can be transformed into a beautiful and healthy smile.

WemayNeedtoRemoveoneorMoreTeethBeforeApplyingBraces

“To gain something, sometimes you have to give up something else.”

No, that isn't the latest viral meme on the Internet. It's actually a practical consideration that could arise in orthodontics.

In this case, the “something” to gain is a straighter, more attractive smile; the “something” you may have to part with is a few teeth. This may be necessary if there are too many teeth on a dental arch for its capacity, a situation called crowding. A lack of space is the main reason teeth come in misaligned.

Before we can correct this, we'll need to free up space to allow for tooth movement by removing one or more of the existing teeth. The ideal candidates are those that are near to the teeth we wish to move but not highly visible. The first bicuspids are the most frequent choices for removal: they're located behind the cuspids or eyeteeth (the pointed teeth right under the eyes).

Ideally, we'll remove the target teeth some time before we apply braces to give the gums a chance to heal. At the same time we want to preserve the bone that once supported the teeth we've extracted. This is because when we chew the forces generated by the teeth stimulates bone replacement growth. When a tooth is no longer there the supporting bone doesn't receive this stimulation and may ultimately reduce in volume.

We may try to prevent this by placing a bone graft in the empty socket immediately after removing the tooth. The graft serves as a scaffold to encourage new bone to grow. Hopefully when we're ready to apply braces, the bone will be strong and healthy to handle the movement of the teeth.

As the teeth move under the influence of braces, they'll begin to fill up the space created by tooth removal. Once it's completed, the extracted teeth won't be missed — the other teeth now straightened will completely fill out the smile.

The different steps in this process must be carefully planned and executed precisely, and it will take months or even years to complete. In the end, though, this complicated bite problem can be corrected and replaced with an attractive, straight smile.

If you would like more information on correcting a poor bite, 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 “Tooth Removal for Orthodontic Reasons.”

BoneGraftingMightbeNecessaryBeforeYouObtainanImplant

Every year dentists place over 5 million dental implants for lost teeth, often removing the problem tooth and installing the implant at the same time. But getting a “tooth in a day” depends on a number of health factors, especially whether or not there’s adequate bone available for the implant. Otherwise, the implant’s placement accuracy and success could be compromised.

Bone loss can be a similar problem when a tooth has been missing for a long period of time. If this describes your situation, you may have already lost substantial bone in your jaw. To understand why, we need to know a little about bone’s growth cycle.

When bone cells reach the end of their useful life, they’re absorbed into the body by a process called resorption.  New cells then form to take the older cells’ place in a continuous cycle that keeps the bone healthy and strong. Forces generated when we chew travel through the teeth to the bone and help stimulate this growth. But when a tooth is missing, the bone doesn’t receive this stimulus. As a result, the bone may not replace itself at a healthy rate and diminish over time.

In extreme cases, we may need to consider some other dental restoration other than an implant. But if the bone loss isn’t too severe, we may be able to help increase it through bone grafting. We insert safe bone grafting material prepared in a lab directly into the jaw through a minor surgical procedure. The graft then acts like a scaffold for bone cells to form and grow upon. In a few months enough new bone may have formed to support an implant.

Bone grafting can also be used if you’re having a tooth removed to preserve the bone even if you’re not yet ready to obtain an implant. By placing a bone graft immediately after extraction, it’s possible to retain the bone for up to ten years—enough time to decide on your options for permanent restoration.

Whatever your situation, it’s important that you visit us as soon as possible for a complete examination. Afterward we can assess your options and hopefully come up with a treatment strategy that will eventually include smile-transforming dental implants.

DontBreakItLikeBeckham

During his former career as a professional footballer (that's a soccer star to U.S. sports fans) David Beckham was known for his skill at “bending” a soccer ball. His ability to make the ball curve in mid-flight — to avoid a defender or score a goal — led scores of kids to try to “bend it like Beckham.” But just recently, while enjoying a vacation in Canada with his family, “Becks” tried snowboarding for the first time — and in the process, broke one of his front teeth.

Some fans worried that the missing tooth could be a “red card” for Beckham's current modeling career… but fortunately, he headed straight to the dental office as soon as he arrived back in England. Exactly what kind of treatment is needed for a broken tooth? It all depends where the break is and how badly the tooth is damaged.

For a minor crack or chip, cosmetic bonding may offer a quick and effective solution. In this procedure, a composite resin, in a color custom-made to match the tooth, is applied in liquid form and cured (hardened) with a special light. Several layers of bonding material can be applied to re-construct a larger area of missing tooth, and chips that have been saved can sometimes be reattached as well.

When more tooth structure is missing, dental veneers may be the preferred restorative option. Veneers are wafer-thin shells that are bonded to the front surface of the teeth. They can not only correct small chips or cracks, but can also improve the color, spacing, and shape of your teeth.

But if the damage exposes the soft inner pulp of the tooth, root canal treatment will be needed to save the tooth. In this procedure, the inflamed or infected pulp tissue is removed and the tooth sealed against re-infection; if a root canal is not done when needed, the tooth will have an increased risk for extraction in the future. Following a root canal, a tooth is often restored with a crown (cap), which can look good and function well for many years.

Sometimes, a tooth may be knocked completely out of its socket; or, a severely damaged tooth may need to be extracted (removed). In either situation, the best option for restoration is a dental implant. Here, a tiny screw-like device made of titanium metal is inserted into the jaw bone in a minor surgical procedure. Over time, it fuses with the living bone to form a solid anchorage. A lifelike crown is attached, which provides aesthetic appeal and full function for the replacement tooth.

So how's Beckham holding up? According to sources, “David is a trooper and didn't make a fuss. He took it all in his stride." Maybe next time he hits the slopes, he'll heed the advice of dental experts and wear a custom-made mouthguard…

If you have questions about restoring damaged teeth, please contact our office to schedule a consultation. You can read more in the Dear Doctor magazine articles “Trauma and Nerve Damage to Teeth” and “Children's Dental Concerns and Injuries.”

StopGumDiseaseBeforeitBecomesaMajorHealthIssue

If you think gum disease only happens to the other guy (or gal), think again. If you’re over 30 you have a 50-50 chance for an infection. After 65 the risk climbs to 70 percent.

Fortunately, we can effectively treat most cases of gum disease. But depending on its severity, treatment can involve numerous intensive sessions and possible surgery to bring the disease under control. So, why not prevent gum disease before it happens?

First, though, let’s look at how gum disease most often begins—with dental plaque, a thin film of bacteria and food particles built up on teeth and gum surfaces. If plaque isn’t consistently removed through daily brushing and flossing, it doesn’t take long—just a few days—for the bacteria to infect the gums.

While it’s not always easy to detect gum disease early on, there are signs to look for like red, swollen and tender gums that bleed easily when you brush or floss, and bad breath or taste. The infection is usually more advanced if you notice pus-filled areas around your gums or loose teeth. If you see any of these (especially advanced signs like loose teeth) you should contact us as soon as possible.

Obviously, the name of the game with prevention is stopping plaque buildup, mainly through daily brushing and flossing. Technique is the key to effectiveness, especially with brushing: you should gently but thoroughly scrub all tooth surfaces and around the gum line, coupled with flossing between teeth.

To find out how well you’re doing, you can rub your tongue along your teeth after you brush and floss—you should feel a smooth, almost squeaky sensation. You can also use plaque-disclosing agents that dye bacterial plaque a particular color so you can easily see surface areas you’ve missed. You can also ask us for a “report card” on how well you’re doing during your next dental visit.

Dental visits, of course, are the other essential part of gum disease prevention—at least every six months (or more, if we recommend) for cleaning and checkups. Not only will we be able to remove hard-to-reach plaque and tartar, we’ll also give your gums a thorough assessment. By following this prevention regimen you’ll increase your chances of not becoming a gum disease statistic.

If you would like more information on recognizing and treating gum disease, 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 “How Gum Disease Gets Started.”
