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.

ChrissyTeigensTeeth-GrindingTroubles

It might seem that supermodels have a fairly easy life — except for the fact that they are expected to look perfect whenever they’re in front of a camera. Sometimes that’s easy — but other times, it can be pretty difficult. Just ask Chrissy Teigen: Recently, she was in Bangkok, Thailand, filming a restaurant scene for the TV travel series The Getaway, when some temporary restorations (bonding) on her teeth ended up in her food.

As she recounted in an interview, “I was… like, ‘Oh my god, is my tooth going to fall out on camera?’ This is going to be horrible.” Yet despite the mishap, Teigen managed to finish the scene — and to keep looking flawless. What caused her dental dilemma? “I had chipped my front tooth so I had temporaries in,” she explained. “I’m a grinder. I grind like crazy at night time. I had temporary teeth in that I actually ground off on the flight to Thailand.”

Like stress, teeth grinding is a problem that can affect anyone, supermodel or not. In fact, the two conditions are often related. Sometimes, the habit of bruxism (teeth clenching and grinding) occurs during the day, when you’re trying to cope with a stressful situation. Other times, it can occur at night — even while you’re asleep, so you retain no memory of it in the morning. Either way, it’s a behavior that can seriously damage your teeth.

When teeth are constantly subjected to the extreme forces produced by clenching and grinding, their hard outer covering (enamel) can quickly start to wear away. In time, teeth can become chipped, worn down — even loose! Any dental work on those teeth, such as fillings, bonded areas and crowns, may also be damaged, start to crumble or fall out. Your teeth may become extremely sensitive to hot and cold because of the lack of sufficient enamel. Bruxism can also result in headaches and jaw pain, due in part to the stress placed on muscles of the jaw and face.

You may not be aware of your own teeth-grinding behavior — but if you notice these symptoms, you might have a grinding problem. Likewise, after your routine dental exam, we may alert you to the possibility that you’re a “bruxer.” So what can you do about teeth clenching and grinding?

We can suggest a number of treatments, ranging from lifestyle changes to dental appliances or procedures. Becoming aware of the behavior is a good first step; in some cases, that may be all that’s needed to start controlling the habit. Finding healthy ways to relieve stress — meditation, relaxation, a warm bath and a soothing environment — may also help. If nighttime grinding keeps occurring, an “occlusal guard” (nightguard) may be recommended. This comfortable device is worn in the mouth at night, to protect teeth from damage. If a minor bite problem exists, it can sometimes be remedied with a simple procedure; in more complex situations, orthodontic work might be recommended.

Teeth grinding at night can damage your smile — but you don’t have to take it lying down! If you have questions about bruxism, please contact us or schedule an appointment for a consultation.
