At what age should you begin treating a poor bite? Many might say with braces around late childhood or early adolescence. But some bite problems could be addressed earlier—with the possibility of avoiding future orthodontic treatment.
A crossbite is a good example. In a normal bite, all of the upper teeth slightly cover the lower when the jaws are shut. But a crossbite occurs when some of the lower teeth, particularly in back, overlap the upper teeth. This situation often happens when the upper jaw develops too narrowly.
But one feature of a child's mouth structure provides an opportunity to intervene and alter jaw development. During a child's early years, the palate (roof of the mouth) consists of two bones next to each other with an open seam running between them. This seam, which runs through the center of the mouth from front to back, will fuse during puberty to form one continuous palatal bone.
An orthodontist can take advantage of this separation if the jaw isn't growing wide enough with a unique device called a palatal expander. This particular oral appliance consists of four, thin metal legs connected to a central mechanism. The orthodontist places the expander against the palate and then uses the mechanism to extend the legs firmly against the back of the teeth on both sides of the jaw.
The outward pressure exerted by the legs also widens the seam between the two palatal bones. The body will respond to this by adding new bone to the existing palatal bones to fill in the widened gap. At regular intervals, the patient or a caregiver will operate the mechanism with a key that will continue to widen the gap between the bones, causing more expansion of the palatal bones until the jaw has grown to a normal width.
The palatal expander is most effective when it's applied early enough to develop more bone before the seam closes. That's why it's important for children to undergo bite evaluation with an orthodontist around age 6. If it appears a bite problem is developing, early interventions like a palatal expander could slow or stop it before it gets worse.

Dentists extract millions of teeth each year, mostly because of disease. But sometimes a healthy tooth is removed to gain a more favorable, long-term dental health outcome.
An example of this is extracting teeth for the sake of orthodontic treatment. This is often beneficial when treating bite problems caused by crowding, a condition in which not enough space on the jaw exists to accommodate all of the teeth coming in. When this happens, the limited space can force teeth out of their proper alignment.
Crowding also complicates correcting the bite problem with braces: As with the eruption phase, there's no available room for orthodontic movement. One solution that may arise after a detailed examination is to open up space on the jaw by removing some of the teeth.
Planning this kind of tooth extrication requires careful forethought with the end in mind—ultimately, the dental providers involved want the resulting appearance after braces to look as natural as possible. For that reason, dentists usually choose teeth for extraction that are outside of the "smile zone" (the teeth visible while smiling) like premolars and molars.
Additionally, dentists are concerned about bone loss after extracting the teeth. Bone often diminishes around empty tooth sockets, especially if those sockets were damaged during extraction. This loss in bone can weaken the jaw structure and cause significant problems while moving teeth with braces.
To avoid this, dentists take great care during tooth removal not to damage the socket. Additionally, they may place a bone graft within the socket immediately after removing the tooth, especially if the space will remain vacant for a significant period of time. A bone graft serves as a scaffold upon which new bone cells can form and accumulate.
After the extractions, the orthodontist may then proceed with correcting the bite. Patients may also need some form of prosthetic teeth to fill in the spaces while wearing braces. Often prosthetic teeth can be incorporated with the braces for a more natural look. After braces, any remaining gaps may require further restoration, either with dentures, bridges or, later in adulthood, dental implants.
Complex bite problems like crowding pose unique challenges in correcting them. But using techniques like tooth extraction can help achieve a successful and satisfactory outcome.

Braces are so common that we often view them as "ho-hum." But there are aspects about braces that make them remarkable. For one, the fact that we can move teeth at all is a wonder of nature.
We normally experience our teeth as firmly set in the jaw, which can easily lead to assuming they're permanently fixed to the bone. They're not. Teeth are actually held in place by a fibrous gum tissue called the periodontal ligament that lies between them and the jawbone. The ligament anchors to both with tiny fibers, which on the tooth side affixes within a thin substance called cementum deposited on the tooth root.
As we said, we don't normally notice teeth moving. But the periodontal ligament does allow movement on a miniscule scale as a response to normal pressures that accompany biting and chewing. Although we're unaware of it, this movement takes place as the bone and cementum ahead of the direction of movement begin to dissolve. Simultaneously, new bone and cementum develops on the other side of the tooth to stabilize the movement.
Orthodontic treatment takes advantage of this natural process. The anchored wires of braces through attached brackets place pressure on the teeth in the intended direction for tooth movement. The natural mechanism described earlier does the rest. Over time, orthodontists have developed an amazing amount of precision working within this mechanism.
Another aspect about braces and other methods we may take for granted is our motive for even trying to move teeth in the first place. It may seem we're only realigning teeth to produce a more attractive smile—which they can do and why we often refer to braces as the "original smile makeover." But there's an even greater desire—straightening teeth can improve dental health.
Poor bites in turn cause other problems. Misaligned teeth are more difficult to keep clean of bacterial plaque, which increases the risk of disease. A poor bite can also accelerate teeth wear and contribute to gum problems like recession. We can eliminate or minimize these problems through bite correction.
Whatever your age, braces or other means can vastly benefit your health and your appearance. They may not always seem so, but braces are one of the true wonders of dental care.

It's been a rough year for all of us, but especially for Simon Cowell. The famous entrepreneur and brutally honest talent judge on American Idol and America's Got Talent underwent emergency back surgery in August after an accident on a new electric bike. But the good news is he's well on his way to recovery—and well enough in October to undergo another, less-stressful, procedure: a smile makeover with dental veneers.
This latest trip to the dentist wasn't Cowell's first experience with the popular restoration, wanting this time to update his smile to more closely resemble what he had when he was younger. He even brought along some older photos for reference.
Veneers aren't exclusive to celebrities like Simon Cowell, as thousands of people who get them every year can attest. These thin wafers of porcelain bonded to teeth can mask a wide range of defects, from chips, wear or discoloration to slight tooth gaps or misalignments. And every veneer is custom-made to match an individual patient's dental dimensions and coloring.
If you're thinking about a smile upgrade, here are a few reasons to consider dental veneers.
More bang for your buck. Compared to other transformative cosmetic options, veneers are relatively affordable, with the cost dependent largely on the extent of your dental needs. Still, dental veneers are an investment that can give long-lasting yields of a more attractive smile and even a completely new look.
Little to no tooth alteration. In most veneer cases, we need only remove a small amount of enamel so the veneers don't appear bulky (the alteration is permanent, though, so you'll need a veneer on the tooth from then on). It's also possible to get “no-prep” veneers requiring little to no alteration.
Durable and long-lasting. Continuing improvements in porcelain and other dental ceramics have led to stronger forms that can better withstand the biting forces your teeth encounter every day. Although you'll still need to be careful biting into hard items, your veneers can last for several years.
Easy to maintain. Veneer cleaning and maintenance is much the same as with natural teeth—daily brushing and flossing, and regular dental cleanings and checkups. Outside of that, you'll need to watch what you chomp down on: Veneers are strong, but not indestructible, and they can break.
As Simon Cowell knows, getting veneers isn't difficult. It starts with an initial visit so we can evaluate your dental health and needs. From there, we can present options on how to update your smile.

If you've decided on a dental implant to replace a missing tooth, you've made a great choice. Implants are a big favorite of both dentists and patients, not only for their life-likeness, but also their durability. Studies show that more than 95% of implants survive after ten years.
As you may know, single tooth implants are composed of two main parts: a metal post (usually titanium) imbedded in the jawbone; and a life-like crown affixed to the end of the post. But what you may not know is that there are two ways to attach the crown—either with screws or with dental cement.
Neither way is superior to the other—both have their own set of advantages and disadvantages. A cemented crown, for instance, usually looks more like a natural tooth than a screw-retained crown (more about that later) and dentists have more flexibility in making them look natural.
But cemented crowns require an additional piece of hardware called an abutment to better match it with the implant, something unnecessary with a screw-retained crown. Some people can also experience a reaction to the cement resulting in inflammation or even bone loss. And once installed, removing the crown later for repair or replacement is much more difficult than with a screw-retained crown.
Besides attaching directly to the implant, screw-retained crowns don't require cement and are more easily attached and removed. But the screw-hole can pose some aesthetic problems: Although it can be filled with a tooth-colored filling, the tooth's appearance isn't as ideal as a cemented crown.
So, which one is best for you? That will depend on the type and location of teeth being replaced, as well as your dentist's preferences. For instance, a more attractive cemented crown may be better for a visible front tooth, while a screw-retained crown might be a good choice for a back premolar or molar where appearance isn't as big a factor.
In the end, it's likely your dentist will discuss the pros and cons for each method as it pertains to your individual case. Whichever way your crown attaches, the end result will still be a life-like tooth that could last you for years to come.
