While braces are often the stars for straightening smiles, they're not the only cast members in an orthodontic production. Orthodontists occasionally turn to other appliances if the bite problem is challenging. Whatever the tool, though, they usually have something in common—they use the principle of anchorage.
To understand anchorage, let's first consider the classic kid's game Tug of War. With teams on either end of a rope, the object is to pull the opposing team across the center line before they pull you. To maximize your pulling force, the player at the back of your rope, usually your stoutest member, holds steady or "anchors" the rest of the team.
Like a Tug of War team, braces exert force against the teeth. This stimulates the supporting periodontal ligament to remodel itself and allow the teeth to move. The braces use the teeth they are attached to as anchors, which in a lot of cases are the back teeth. By attaching a thin wire to the brackets or braces on the teeth, the orthodontist includes all the teeth on the arch, from one end to the other. Anchored in place, the wire can maintain a constant pressure against the teeth to move them.
But not all bite situations are this straightforward. Sometimes an orthodontist needs to influence jaw growth in addition to teeth movement. For this purpose, they often use orthodontic headgear, which runs around the back of the head or neck and attaches to orthodontic brackets on the teeth. It still involves an anchor but in this case it's the patient's own skull.
In some situations, an orthodontist may feel he or she needs more anchorage as the teeth alone may not be enough. For this, they might establish a separate or additional anchor point using a temporary anchorage device (TAD). A TAD resembles a tiny screw that's inserted into the jawbone near the tooth intended for movement. The orthodontist can then attach the TAD to braces hardware using some form of elastics. After treatment, they remove the TAD.
These are just a couple examples of specialized tools an orthodontist can use for bite correction. Thanks to them and similar devices, even the most complex bite problem can be overcome to create a healthier and more attractive smile.

When a tooth is beyond repair due to disease or injury, it may be necessary to remove it. A “simple” tooth extraction is among the most common in dentistry and certainly not the agonizing procedure depicted in common lore.
They’re referred to as simple extractions because the shape of the tooth and root allows for a fairly straightforward and uncomplicated removal. An example would be the normally cone-shaped upper front tooth that doesn’t offer a lot of resistance during the extraction process.
The process itself is fairly straightforward. Teeth are held in place by the periodontal ligament, an elastic tissue made of tiny fibers that attaches the tooth to the supporting bone. These fibers can be dislodged from the tooth with some careful manipulation — in the hands of an experienced dentist there’s a deft “feel” to the fibers loosening. Once they’ve detached, it requires little effort to remove the tooth; with the aid of local anesthesia, you won’t feel anything but a little pressure.
Immediately after the tooth is removed, we commonly insert bone grafting material in the socket to minimize bone loss until a permanent replacement like a dental implant can be installed after tissue healing. We then place sterile gauze over the site for a few minutes to control bleeding and, depending on the size of the wound opening, we may also place a few stitches to close it. We then give you instructions for caring and cleaning the site over the next few days, and prescribe antibiotics to reduce the chance of infection and anti-inflammatory drugs for any discomfort.
Although a simple extraction is a routine procedure, it’s important to perform a proper assessment of the tooth and the surrounding bone beforehand, including x-rays to determine the tooth’s exact shape and position. If we discover a complication that makes a simple extraction impractical (like multiple roots at acute angles), we may then refer you to an oral surgeon for a more complicated surgical extraction.
It’s our hope you’ll have your natural teeth for as long as you live. But if you must have one removed, you can rest assured it’s a common — and uneventful — experience.

As Spring turns to Summer, millions of students will depart high school in the time-honored rite of passage called graduation. At the same time, quite a few of these graduates will be experiencing another maturity milestone: the eruption (coming in) of their last permanent teeth.
Typically, these are the back third molars, better known as “wisdom teeth,” emerging on either end of both the top and bottom jaws sometime between the ages of 18 and 24. Their arrival heralds the end of a long development process that began in infancy.
But this auspicious event can give rise to dental problems. Because they’re the last to come in, wisdom teeth often erupt in an environment crowded by earlier teeth. Depending on jaw size and other factors, there may not be enough room for a normal eruption.
Wisdom teeth can thus erupt out of position, creating a poor bite (malocclusion). Or they might not erupt at all—becoming stuck fully or partially within the gums and bone, a condition known as impaction. Impacted teeth can also cause problems for the adjacent teeth, damaging the roots of the second molars or disrupting the surrounding gum tissue, making them more susceptible to periodontal (gum) disease.
Because of these and other issues, impacted wisdom teeth are among the most common type of teeth removed: an estimated 10 million each year. And many of these are removed before they show signs of disease or complications as a preemptive strike against developing dental problems.
Although unnecessary surgery should always be avoided, according to some research, there’s a one in three chance that erupting wisdom teeth that are not showing signs of trouble will eventually become problematic. And the earlier they’re removed, the lower the risk of post-extraction complications.
Wisdom teeth should always be evaluated on a case by case basis. Those with obvious signs of disease or complications do require prompt treatment, including possible extraction. Others that are asymptomatic can be monitored over time: If they’re tending to become problematic, we can adjust the treatment plan accordingly. Our goal is to ensure these particular teeth signaling the end of childhood won’t detract from dental health in adulthood, so a measured approach seems to be the best and safest one.
