Applying braces or clear aligners to move misaligned teeth is only part of an orthodontist's overall mission to eliminate poor bites (malocclusions). Sometimes a malocclusion isn't caused by the teeth at all—the size of the jaw is the problem!
One type in particular, a cross-bite, often happens because the upper jaw has developed too narrowly. As a result, many of the upper teeth fit inside the lower, the opposite of normal. But a tool called a palatal expander can alleviate the problem if it's applied at an early enough age.
The device works because the upper jawbone initially forms as two halves that fit together along a center line in the roof of the mouth (the palate) running from the back of the mouth to the front. These two bone halves remain separate during childhood to facilitate jaw growth, but eventually fuse around puberty.
Consisting of two sets of wire arms joined together by a hinge mechanism in the middle, the expander device is positioned up against the palate. The orthodontist extends each arm to press against the inside of the back teeth, then adds more outward pressure by turning the mechanism in the middle with a small key. During wear, the patient or caregiver will turn the mechanism in the same way to keep up the pressure on the two sides of the jaw.
This continual pressure keeps the two bones moving away from each other and maintaining a center gap between them. In response, more bone forms on the two halves to fill the gap. In time, the newly formed bone should widen the jaw enough to correct any developing malocclusion.
Timing is everything with a palatal expander—if not used before the jaw bones fuse, the patient will need a surgical procedure to separate the bones to pursue treatment. To catch the problem early enough, children should have an orthodontic evaluation on or before they turn six. An orthodontist may be able to identify this or other emerging bite problems and intervene before it becomes worse. Taking this approach can help save you and your child more expensive orthodontic treatment down the road.

Multi-platinum recording artist Janet Jackson has long been known for her dazzling smile. And yet, Jackson admitted to InStyle Magazine that her trademark smile was once a major source of insecurity. The entertainer said, “To me, I looked like the Joker!” It was only after age 30 that the pop icon came to accept her unique look.
Jackson is not alone. A study commissioned by the American Association of Orthodontists found that more than one third of U.S. adults are dissatisfied with their smile. But there’s good news—modern dentistry can correct many flaws that can keep you from loving your smile, whether you’re unhappy with the color, size, or shape of your teeth. Here are some popular treatments:
Professional teeth whitening: Sometimes a professional teeth whitening will give you the boost you need. In-office whitening can dramatically brighten your smile in just one visit.
Tooth-colored fillings: If you have silver-colored fillings on teeth that show when you smile, consider replacing them with unnoticeable tooth-colored fillings.
Dental bonding: If you have chipped, cracked, or misshapen teeth, cosmetic bonding may be the fix you’re looking for. In this procedure, tooth colored material is applied to the tooth’s surface, sculpted into the desired shape, hardened with a special light, and polished for a smooth finish.
Porcelain veneers: Dental veneers provide a natural-looking, long-lasting solution to many dental problems. These very thin shells fit over your teeth, essentially replacing your tooth enamel to give you the smile you desire.
Replacement teeth: Is a missing tooth affecting your self-confidence? There are several options for replacing missing teeth, from a removable partial denture to a traditional fixed bridge to a state-of-the-art implant-supported replacement tooth. Removable partial dentures are an inexpensive way to replace one or more missing teeth, but they are less stable than non-removable options. Dental bridges, as the name implies, span the gap where a tooth is missing by attaching an artificial tooth to the teeth on either side of the space. In this procedure, the teeth on both sides of the gap must be filed down in order to support the bridgework. Dental implants, considered the gold standard in tooth replacement technology, anchor long-lasting, lifelike replacements that function like natural teeth.
After coming to embrace her smile, Jackson asserted, “Beautiful comes in all shapes, sizes, and colors." If you don’t feel that your smile expresses the beauty you have inside, call our office to schedule a consultation. It’s possible to love your smile. We can help.

As your dental provider, we're always alert for signs of tooth decay or periodontal (gum) disease, the two leading causes of tooth loss. But we're also watching for less common conditions that could be just as devastating.
Root resorption falls into this latter category: it occurs when a tooth's root structure begins to break down and dissolve (or resorb). It's a normal process in primary ("baby") teeth to allow them to loosen and give way when permanent teeth are ready to erupt.
It's not normal, though, for permanent teeth. Something internally or—more commonly—externally causes the root structure to break down. External resorption usually occurs at the neck-like or cervical area of a tooth around the gum line. Known as external cervical resorption (ECR), it can first appear as small, pinkish spots on the enamel. These spots contain abnormal cells that cause the actual damage to the root.
We don't fully understand how root resorption occurs, but we have identified certain factors that favor its development. For example, it may develop if a person has experienced too much force against the teeth during orthodontic treatment. Injury to the periodontal ligaments, teeth-grinding habits or some dental procedures like internal bleaching may also contribute to later root resorption.
Early diagnosis is a major part of effective treatment for root resorption. Because it's usually painless and easily overlooked, resorption is often too difficult to detect in its early stages without x-rays—a good reason for regular dental exams. Beginning spots or lesions are usually small enough to surgically remove the tissue cells causing the damage and then filled with a tooth-colored filling material. If it has advanced further, we may also need to perform a root canal treatment.
At some point, the damage from root resorption can be too great, in which case it might be best to remove the tooth and replace it with a dental implant or similar restoration. That's why catching root resorption early through regular dental exams can give you the edge for saving your tooth.
