TheSimpleBitewingX-RayisaGameChangerforMaintainingDentalHealth

X-rays are such a routine part of dental care that it's easy to overlook how much this technology has revolutionized detecting and treating tooth decay. It's safe to say x-rays have helped save hundreds of millions of teeth over the last hundred years.

Thanks to its unique properties these invisible electro-magnetic waves give us precise images of the interior structure of teeth and gums. It's so precise that we can clearly detect even a small spot of softened, decayed tooth structure on an exposed x-ray film, often before it becomes visible to the naked eye. As a result, we can begin treating the decay earlier, minimizing the damage and increasing the chances for preserving the tooth.

There are a variety of ways we can utilize x-ray technology in diagnosing dental problems. The one, though, that's used the most is called the bitewing. The name comes from wing-like tabs extending out from a thin frame holding a segment of unexposed film. A technician places the frame inside the patient's mouth with the film on the tongue side of the teeth, and has them bite down on the tabs to hold the frame still. They then aim a camera at the patient's outer cheek, which then emits a very short burst of x-ray energy to expose the film.

Bitewings are popular because they give a full view of the back and side teeth, where decay is often hard to detect, with very little radiation exposure to the patient. And as x-ray technology has progressed over the years with digital processing and more efficient equipment, we can acquire sharper images with even less exposure. We've also developed standard protocols for when and how often we perform x-rays, so that we're getting the most diagnostic benefit for the least amount of exposure time.

Those few minutes getting an x-ray may seem routine, but the benefits to your dental health are truly amazing. The bitewing and other forms of x-rays play a huge role in helping us keep your teeth as healthy as they possibly can.

Have you decided to put up with a less-than-perfect smile because you don't like the thought of wearing metal braces? There's no need toInvisalign live with misaligned teeth when Invisalign offers a discreet way to improve your smile. Our Jacksonville, FL, orthodontist, Dr. Kok-Tow Ng, offers Invisalign and can tell you if you would benefit from the clear brace alternative.

What is Invisalign?

Invisalign's clear aligner trays gradually change the position of your teeth. The trays fit over your upper and lower teeth snugly. Every two weeks, you'll begin wearing a new set of trays, which will help you achieve your straightening goals. Trays are usually worn for 20 to 22 hours per day.

Who can benefit from Invisalign?

Invisalign may be a good choice if:

  • You don't like the way metal braces look. Invisalign's clear aligner trays don't draw attention to your teeth. In fact, some people may not even realize that you're straightening your teeth, thanks to the nearly transparent trays.
  • You have a mild to moderate bite problem. Invisalign is an excellent choice if you want to correct an overbite, underbite, crossbite, open bite, crooked teeth, or spacing issues. If your orthodontic problem is severe, metal braces may still be the best option.
  • A complicated oral hygiene routine isn't for you. If you know you don't have the patience to clean under and around wires and brackets, Invisalign offers a better option. When you're ready to brush and floss, you'll remove your aligners, then rinse them and put them back in your mouth.
  • You don't want to give up certain foods. Any type of food that can damage your wires must be avoided when you wear metal braces. You'll need to give up gum, popcorn, some types of raw vegetables, corn on the cob and other foods for the entire time you wear your braces. Fortunately, changes to your diet aren't necessary with Invisalign. Because you'll take out your trays before you eat, you won't have any food restrictions at all.

Invisalign offers a clear advantage when it comes to improving your smile. Call our Jacksonville, FL, orthodontist, Dr. Ng, at (904) 731-0521 to schedule your appointment to discuss orthodontic options.

ALong-TermOrthodonticStrategyCouldHelpEnsureanAttractiveSmileLaterinLife

Orthodontics relies on certain mechanics in the mouth to move teeth to better positions. As the specialty has advanced, we've become ever more precise in moving teeth with braces, the “workhorse” of orthodontics, and other specialized appliances and techniques.

But although cooperating effectively with the mouth's natural ability for tooth movement is crucial for success, there's another aspect to consider if that success will be long-term: the growth and development of oral and facial structure. And not just development during childhood and adolescence: indeed, facial structure continues to change throughout a lifetime, including the senior years. Research has shown that although the rate of growth slows over time, it doesn't stop even for someone 80 years or older.

Our emerging understanding in this area has had an important impact on how and when we perform orthodontic treatment. As we develop a treatment strategy for an individual patient we consider not only the immediate outcome of a treatment, but also how it may change their facial appearance in the future. By taking continuing facial growth into consideration, we're more likely to achieve a new smile appearance that remains attractive later in life.

A key factor is to be sure we're initiating treatments at appropriate ages. We may detect developing bite problems as early as age 6, which might prompt preventive treatment at that time to diminish or even eliminate the problem. But it may also be prudent to wait on full-scale orthodontic treatment until late childhood or puberty. Furthermore, some form of orthodontic treatment might need to continue into early adulthood to ensure the most optimal outcome.

By taking a longer view of the treatment process, we're better able to work within the natural growth and development taking place now and in the future. As a result, a person is more likely to enjoy an attractive and youthful appearance even in their later years.

FifthHarmonysCamilaCabelloChipsaToothbutConcertStillWorthIt

Everyone loves a concert where there's plenty of audience participation… until it starts to get out of hand. Recently, the platinum-selling band Fifth Harmony was playing to a packed house in Atlanta when things went awry for vocalist Camila Cabello. Fans were batting around a big plastic ball, and one unfortunate swing sent the ball hurtling toward the stage — and directly into Cabello's face. Pushing the microphone into her mouth, it left the “Worth It” singer with a chipped front tooth.

Ouch! Cabello finished the show nevertheless, and didn't seem too upset. “Atlanta… u wild… love u,” she tweeted later that night. “Gotta get it fixed now tho lol.” Fortunately, dentistry offers a number of ways to make that chipped tooth look as good as new.

A small chip at the edge of the tooth can sometimes be polished with dental instruments to remove the sharp edges. If it's a little bigger, a procedure called dental bonding may be recommended. Here, the missing part is filled in with a mixture of plastic resin and glass fillers, which are then cured (hardened) with a special light. The tooth-colored bonding material provides a tough, lifelike restoration that's hard to tell apart from your natural teeth. While bonding can be performed in just one office visit, the material can stain over time and may eventually need to be replaced.

Porcelain veneers are a more long-lasting solution. These wafer-thin coverings go over the entire front surface of the tooth, and can resolve a number of defects — including chips, discoloration, and even minor size or spacing irregularities. You can get a single veneer or have your whole smile redone, in shades ranging from a pearly luster to an ultra-bright white; that's why veneers are a favorite of Hollywood stars. Getting veneers is a procedure that takes several office visits, but the beautiful results can last for many years.

If a chip or crack extends into the inner part of a tooth, you'll probably need a crown (or cap) to restore the tooth's function and appearance. As long as the roots are healthy, the entire part of the tooth above the gum line can be replaced with a natural-looking restoration. You may also need a root canal to remove the damaged pulp material and prevent infection if the fracture went too far. While small chips or cracks aren't usually an emergency (unless accompanied by pain), damage to the tooth's pulp requires prompt attention.

YourChildsImpactedFrontTeethcanbeSaved-butDontWaittooLong

Children's permanent teeth normally erupt over several years after first forming below the gum line. All their permanent teeth should come in by the time they reach early adolescence.

Unfortunately, this process doesn't always happen as it should. If the erupting teeth become crowded due to a poor bite (malocclusion), teeth still to come in may not have enough room to fully erupt. They become impacted, a condition in which the visible crown remains partially or completely submerged below the gum line.

Impacted teeth create consequences for other teeth and dental health overall. They more readily cause abscesses (a localized infection within the gum tissue) and can damage the roots of nearby teeth. Impacted front canine (eye) teeth can interfere with bite function and their visual absence mars an otherwise attractive smile.

If your child's canine teeth have failed to erupt properly, there is a way to help them fully come in if you act before their mouth structure fully matures. The first step is an orthodontic evaluation of their entire bite. This will determine if there's enough space to move other teeth to make room for the impacted canines.

If so, we would then find the exact position of the impacted teeth using x-rays and possibly cone beam CT scanning for a detailed three-dimensional image. The teeth could be in a variety of positions, such as angled toward the roof of the mouth or cheek or buried high in the jawbone. If the teeth are too far out of position the best course of action may be to remove them and replace them later with a dental implant.

If the impacted teeth, though, are in a feasible position for retrieval, we first expose each tooth through the gums with a minor surgical procedure and bond a small bracket to it. We then attach a small gold chain to the bracket that loops over an orthodontic appliance attached to other teeth. The appliance will exert pressure over several months to pull the tooth into proper position.

If successful, your child will gain the use of these important teeth and a more attractive appearance. But don't delay — this desired outcome will become much harder if not impossible to attain as their teeth and jaws continue to develop.
