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.

In real life he was a hard-charging basketball player through high school and college. In TV and the movies, he has gone head-to-head with serial killers, assorted bad guys… even mysterious paranormal forces. So would you believe that David Duchovny, who played Agent Fox Mulder in The X-Files and starred in countless other large and small-screen productions, lost his front teeth… in an elevator accident?
“I was running for the elevator at my high school when the door shut on my arm,” he explained. “The next thing I knew, I was waking up in the hospital. I had fainted, fallen on my face, and knocked out my two front teeth.” Looking at Duchovny now, you’d never know his front teeth weren’t natural. But that’s not “movie magic” — it’s the art and science of modern dentistry.
How do dentists go about replacing lost teeth with natural-looking prosthetics? Today, there are two widely used tooth replacement procedures: dental implants and bridgework. When a natural tooth can’t be saved — due to advanced decay, periodontal disease, or an accident like Duchovny’s — these methods offer good looking, fully functional replacements. So what’s the difference between the two? Essentially, it’s a matter of how the replacement teeth are supported.
With state-of-the-art dental implants, support for the replacement tooth (or teeth) comes from small titanium inserts, which are implanted directly into the bone of the jaw. In time these become fused with the bone itself, providing a solid anchorage. What’s more, they actually help prevent the bone loss that naturally occurs after tooth loss. The crowns — lifelike replacements for the visible part of the tooth — are securely attached to the implants via special connectors called abutments.
In traditional bridgework, the existing natural teeth on either side of a gap are used to support the replacement crowns that “bridge” the gap. Here’s how it works: A one-piece unit is custom-fabricated, consisting of prosthetic crowns to replace missing teeth, plus caps to cover the adjacent (abutment) teeth on each side. Those abutment teeth must be shaped so the caps can fit over them; this is done by carefully removing some of the outer tooth material. Then the whole bridge unit is securely cemented in place.
While both systems have been used successfully for decades, bridgework is now being gradually supplanted by implants. That’s because dental implants don’t have any negative impact on nearby healthy teeth, while bridgework requires that abutment teeth be shaped for crowns, and puts additional stresses on them. Dental implants also generally last far longer than bridges — the rest of your life, if given proper care. However, they are initially more expensive (though they may prove more economical in the long run), and not everyone is a candidate for the minor surgery they require.

We often associate orthodontics with moving several teeth on the upper or lower arches (or both) with braces or clear aligners. But not all patients require a major endeavor — sometimes only one or a few teeth need to be moved, and not very far.
A slight gap between the two upper front teeth is one type of situation that only requires minor tooth movement: just a few teeth need to be moved and usually just a millimeter or two. The appliances needed to achieve this are also relatively simple in design: removable retainers or small scale fixed braces with small springs or elastics that place pressure against the teeth. The process may also only take a few months rather than two years as with major tooth movement.
Preparing for the procedure, though, must be undertaken with great care. We need to first determine if moving the teeth even slightly could affect the bite with the opposite teeth. We must also ensure the roots of the teeth intended for movement are in good position for allowing the space to be closed.
We must then consider the other supporting structures for the teeth. It’s important for gums and bone to be healthy — if not, treating any found disease may be necessary first before beginning orthodontics. And, if the gap between the two upper teeth was created by an abnormally large frenum, the small strip of tissue connecting the lip to the upper gum, it may be necessary to remove it before tooth movement can begin to ensure the closed gap stays closed.
Like any other orthodontic treatment, minor tooth movement first requires a thorough examination with x-ray imaging to determine the exact tooth position, bite issues and the surrounding gum and bone health. We can then be reasonably certain if this straightforward procedure is right for you, and could help you obtain a more attractive smile.

Like other aspects of our lives, aging can take a toll on our smile. Over a lifetime the effects of disease, teeth wearing and the foods we eat can cause our teeth and gums to look unattractive.
Here are 3 of the most common age-related dental problems and how we can help you "turn back the clock" on each one.
Discoloration. Teeth can dull and grow darker over time. And not just from what we eat or drink—age-related structural changes in the tooth can also cause discoloration. We can often alleviate external staining temporarily with teeth whitening. If the staining is heavy or it originates inside the tooth, then we can install life-like porcelain veneers or crowns to cover the discoloration. We can also use composite dental materials to alter the color of one darkened tooth so that it doesn't stand out from the rest of your teeth.
Wearing. Our teeth naturally wear down over time. If the wearing is excessive, though, teeth can look shorter and less youthful. Again, we can use veneers or crowns to change a tooth's outward appearance and make them look longer. We can also employ enamel contouring and reshaping that smoothes out sharper edges caused by wearing to give your teeth a softer, more youthful look.
Receding gums. On the other end of the spectrum, gums that have shrunk back or receded from the teeth can make them look much larger and unattractive. Our first step is to treat any gum disease present—the most common cause of recession—which often helps the tissues to regenerate. If your case is more advanced, though, you may also need grafting surgery to restore lost gum tissue. Using in-depth microsurgical techniques, surgeons attach grafted gum tissue at the recession site. Over time new tissue will grow, restoring adequate gum coverage.
You can also improve your appearance at any age with orthodontics. Besides a more attractive smile, properly aligned teeth tend to wear more slowly and evenly. This and proper daily oral hygiene and regular dental care can keep your teeth looking younger even in your later years.

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.
