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.

JulianneHoughSharesaVideo-andaSong-AfterWisdomTeethComeOut

Once upon a time, celebrities tried hard to maintain the appearance of red-carpet glamour at all times. That meant keeping the more mundane aspects of their lives out of the spotlight: things like shopping, walking the dog and having oral surgery, for example.

That was then. Today, you can find plenty of celebs posting pictures from the dentist on social media. Take Julianne Hough, for example: In 2011 and 2013, she tweeted from the dental office. Then, not long ago, she shared a video taken after her wisdom teeth were removed in December 2016. In it, the 28-year-old actress and dancer cracked jokes and sang a loopy rendition of a Christmas carol, her mouth filled with gauze. Clearly, she was feeling relaxed and comfortable!

Lots of us enjoy seeing the human side of celebrities. But as dentists, we’re also glad when posts such as these help demystify a procedure that could be scary for some people.

Like having a root canal, the thought of extracting wisdom teeth (also called third molars) makes some folks shudder. Yet this routine procedure is performed more often than any other type of oral surgery. Why? Because wisdom teeth, which usually begin to erupt (emerge from beneath the gums) around age 17-25, have the potential to cause serious problems in the mouth. When these molars lack enough space to fully erupt in their normal positions, they are said to be “impacted.”

One potential problem with impacted wisdom teeth is crowding. Many people don’t have enough space in the jaw to accommodate another set of molars; when their wisdom teeth come in, other teeth can be damaged. Impacted wisdom teeth may also have an increased potential to cause periodontal disease, bacterial infection, and other issues.

Not all wisdom teeth need to be removed; after a complete examination, including x-rays and/or other diagnostic imaging, a recommendation will be made based on each individual’s situation. It may involve continued monitoring of the situation, orthodontics or extraction.

Wisdom tooth extraction is usually done right in the office, often with a type of anesthesia called “conscious sedation.”  Here, the patient is able to breathe normally and respond to stimuli (such as verbal directions), but remains free from pain. For people who are especially apprehensive about dental procedures, anti-anxiety mediation may also be given. After the procedure, prescription or over-the-counter pain medication may be used for a few days. If you feel like singing a few bars, as Julianne did, it’s up to you.

If you would like more information about wisdom tooth extraction, please call our office to arrange a consultation. You can learn more in the Dear Doctor magazine articles “Wisdom Teeth” and “Removing Wisdom Teeth.”

DontStressOverYourChildsTeethGrindingHabitUnlessitPersists

Along with thumb sucking, childhood teeth grinding is one of the top concerns anxious parents bring to their dentists. It’s so prevalent, though, many providers consider it normal behavior—the sleep-disturbing sound it can generate is often the worst consequence for the habit.

But that doesn’t mean you should brush aside all concern, especially if the habit continues into late childhood. Long-term teeth grinding could eventually damage the teeth and gums.

Teeth grinding (or clenching) is the involuntary movement of the jaws when not engaged in normal functions like chewing, speaking or swallowing. The action often produces higher than normal chewing forces, which over time can accelerate tooth wear, cause fractures, or contribute to loose teeth, all of which could increase the risk of dental disease. While it can occur at any time it’s most common among children during nighttime sleep.

While stress is the usual trigger for teeth grinding in adults, with young children the causes for the habit are more complex and less understood. Most doctors hold to the theory that most pediatric teeth grinding arises during shifts from lighter to heavier, rapid-eye-movement (REM) sleep. The child’s immature neuromuscular chewing control may engage involuntarily during this shift. Teeth grinding is also prevalent among children who snore or mouth-breathe, or who take anti-depressant medication.

But as mentioned before, there’s usually no cause for concern unless the habit persists beyond about age 11. If the habit isn’t fading, you should speak to your dentist about ways to reduce it or its effects. One way is with a custom-made night guard worn during sleep. The smooth, plastic surface of the appliance prevents teeth from making solid contact with each other during a grinding episode.

You might also seek treatment from an ear, nose and throat (ENT) specialist if your child is having issues with airway obstruction, which could also relieve teeth grinding. And children experiencing stressful situations or events may find relief both emotionally and physically from psychological therapy.

At younger ages, you can safely regard your child’s grinding habit as normal. But if it persists, it’s worth looking for ways to reduce it.
