PalatalExpansionCouldHeadOffFutureOrthodonticTreatment

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.

ViggoMortensensRed-CarpetSmile

The Golden Globes ceremony is a night when Hollywood stars shine their brightest. At the recent red-carpet event, leading man Viggo Mortensen had plenty to smile about: Green Book, the movie in which he co-starred, picked up the award for Best Motion Picture—Musical or Comedy. But fans looking at the veteran actor's big smile today might not realize that it once looked very different. A few years ago, an accident during the filming of The Two Towers took a major chip out of Mortensen's front tooth!

That might be OK for some movies (think The Hangover or Dumb and Dumber)—but it's not so great for everyday life. Fortunately, Mortensen visited a dentist promptly, and now his smile is picture-perfect. How was that accomplished? He didn't say…but generally, the best treatment for a chipped tooth depends on how much of the tooth's structure is missing.

If the tooth has only a small chip or crack, it's often possible to restore it via cosmetic bonding. This procedure can be done right in the dental office, frequently in a single visit. Here's how it works: First the tooth is cleaned and prepared, and then a tooth-colored resin is applied to the area being restored. After it is cured (hardened) with a special light, additional layers may be applied to build up the missing structure. When properly cared for, a tooth restored this way can look good for several years.

For a longer-lasting restoration, veneers may be recommended. These are wafer-thin shells made of durable material (most often porcelain) that cover the front (visible) surfaces of teeth. Strong and lifelike, veneers can match the exact color of your natural teeth—or give you the bright, high-wattage smile you've always wanted. No wonder they're so popular in Hollywood! Because veneers are custom-made for you, getting them may require several office visits.

If a chip or crack extends to the inner pulp of the tooth, a root canal procedure will be needed to keep the tooth from becoming infected—a situation that could have serious consequences. But you shouldn't fear a root canal! The procedure generally causes no more discomfort than filling a cavity (though it takes a little longer), and it can help save teeth that would otherwise be lost. After a root canal, a crown (cap) is generally needed to restore the visible part of the tooth.

When a damaged tooth can't be restored, it needs to be extracted (removed) and replaced. Today's best option for tooth replacement is a dental implant—a small, screw-shaped post inserted into the bone of your jaw that anchors a lifelike, fully functional crown. Implants require very little special care and can look great for many years, making them a top choice for tooth replacement

If you have questions about chipped or damaged teeth, please contact our office or schedule a consultation. You can read more in the Dear Doctor magazine articles “Artistic Repair Of Front Teeth With Composite Resin” and “Porcelain Veneers.”

TestYoureBrushingandFlossingSuccesswithaPlaqueDisclosingAgent

Brushing and flossing your teeth provides a lot of benefits, including a brighter smile and fresher breath. But the primary benefit—and ultimate goal—is removing dental plaque. This biofilm of bacteria and food remnants on tooth and gum surfaces is the number one cause for dental disease.

Brushing and flossing can effectively keep plaque under control. Unfortunately, plaque can be a stubborn foe, hiding in areas easily missed if you're not thorough enough.

So how do you know you're doing a good job brushing and flossing? One quick way is to use your tongue or dental floss to feel for any grittiness, a possible sign of remaining plaque. Ultimately, your dentist or hygienist can give you the best evaluation of your hygiene efforts during your three or six-month checkup.

But there's another way to find out more definitively how well you're removing plaque in between dental visits: a plaque disclosing agent. These over-the-counter products contain a dye solution that stains plaque so it stands out from clean tooth surfaces.

A disclosing agent, which can come in the form of tablets, swabs or a liquid, is easy to use. After brushing and flossing, you apply the agent according to the product's directions. The dye reacts with plaque to stain it a distinct color. You may also find products with two-tone dyes that stain older and newer plaque different colors to better gauge your overall effectiveness.

You then examine your teeth in the bathroom mirror, looking especially for patterns of missed plaque. For example, if you see dyed plaque running along the gum line, you'll know you need to concentrate your hygiene there.

After observing what you can do to improve your future efforts, you can then brush and floss your teeth to remove as much of the dyed plaque as you can. The staining from the dye is temporary and any remaining will fade over a few hours.

Using a disclosing agent regularly could help you improve your overall hygiene technique and reduce your risk of disease. Ask your dentist for recommendations on products.

YourRegularDentalVisitsMightChangeifYouvehadGumDisease

Periodontal (gum) disease is as common as it is destructive. Almost half of all adults 30 and older have some form—and those numbers increase to nearly three-quarters by age 65.

Fortunately, we have effective ways to treat this bacterial infection, especially if we catch it early. By thoroughly removing all plaque, the disease-causing, bacterial biofilm that accumulates on tooth surfaces, we can stop the infection and help the gums return to normal.

Unfortunately, though, you're at a greater risk for a repeat infection if you've already had gum disease. To lower your chances of future occurrences, we'll need to take your regular dental exams and cleanings to another level.

Although everyone benefits from routine dental care, if you've had gum disease you may see these and other changes in your normal dental visits.

More frequent visits. For most people, the frequency norm between dental cleanings and exams is about six months. But we may recommend more visits for you as a former gum disease patient: depending on the advancement of your disease, we might see you every three months once you've completed your initial treatment, and if your treatment required a periodontist, we may alternate maintenance appointments every three months.

Other treatments and medications. To control any increases in disease-causing bacteria, dentists may prescribe on-going medications or anti-bacterial applications. If you're on medication, we'll use your regular dental visits to monitor how well they're doing and modify your prescriptions as needed.

Long-term planning. Both dentist and patient must keep an eye out for the ongoing threat of another gum infection. It's helpful then to develop a plan for maintaining periodontal health and then revisiting and updating that plan as necessary. It may also be beneficial to perform certain procedures on the teeth and gums to make it easier to keep them clean in the future.

While everyone should take their oral health seriously, there's even greater reason to increase your vigilance if you've already had gum disease. With a little extra care, you can greatly reduce your chances of another bout with this destructive and aggressive disease.

If you would like more information on preventing recurring 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 “Periodontal Cleanings.”

CompositeResinCouldAmpupYourTeethsAttractivenessinJustOneVisit

It might not rise to the level of a miracle, but cosmetic dentistry can achieve some amazing outcomes with unattractive teeth. A skilled and experienced dentist can turn "ugly ducklings" into beautiful "swans." And that achievement might not be as in-depth or expensive as you might think, thanks to the increased use of dental materials called composite resins.

Composite resins are pliable, tooth-colored materials we apply directly to tooth surfaces. They're most often used with broken, chipped or misshapen front teeth—the composite material replaces the missing tooth structure.

Composite resins have been around for decades, but haven't been widely used because they didn't have the strength of dental porcelain. In recent years, though, dentists have perfected techniques for bonding and shaping composites to teeth that have increased their durability. With just the right skill and artistry, composites can look like natural teeth.

We can correct many tooth flaws using composite resins right in our office. After roughening up the outer enamel surface of the tooth and performing other steps to aid bonding, we begin applying liquid resins to form a base layer that we then harden with a special light source. We continue to add layers to increase the color depth and shape of the restoration, before finally polishing it to resemble natural teeth.

Composite restorations are ideal for moderate tooth structure loss, but may not be appropriate for heavily worn, previously root canal-treated or fractured teeth. These and other kinds of flaws may require a different solution such as a dental porcelain restoration with veneers or crowns. Where composites can be used, though, they provide an affordable option that doesn't require an outside dental lab for fabrication—we can often perform it in one visit.

If you'd like to consider a composite resin restoration for a less than perfect tooth, see us for a complete examination and consultation. If your situation appears to be compatible for using this particular technique, composite resins could change your smile for the better in just a few minutes.
