Orthodontics shares a principle with the classic tug of war game: if you want things to move in the right direction you need a good anchor. Anchors help braces and other appliances apply constant pressure to misaligned teeth in the direction they need to go to correct a malocclusion (poor bite).
Orthodontic treatments work in cooperation with an existing oral mechanism that already moves teeth naturally in response to biting forces or other environmental factors. The key to this mechanism is an elastic tissue known as the periodontal ligament that lies between the tooth and the bone. Besides holding teeth in place through tiny attached fibers, the ligament also allows the teeth to move in tiny increments.
Braces’ wires laced through brackets affixed to the teeth exert pressure on them in the desired direction of movement –the periodontal ligament and other structures do the rest. To maintain that pressure we need to attach them to an “anchor”—in basic malocclusions that’s usually the back molar teeth.
But not all malocclusions are that simple. Some may require moving only certain teeth while not moving their neighbors. Younger patients’ jaws and facial structures still under development may also need to be considered during orthodontic treatment. That’s why orthodontists have other anchorage methods to address these possible complications.
One example of an alternate anchorage is a headgear appliance that actually uses the patient’s skull as the anchor. The headgear consists of a strap running around the back of the head and attached in front to orthodontic brackets (usually on molar teeth). The pressure it exerts can trigger tooth movement, but it can also help influence jaw development if an upper or lower jaw is growing too far forward or back.
Another useful anchorage method is a tiny metal screw called a temporary anchorage device (TAD) that is implanted into the jawbone above the teeth through the gums. Orthodontists then attach elastic bands between implanted TADs and specific braces’ brackets or wires to exert pressure on certain teeth but not others with pinpoint accuracy. After treatment the TADs can be easily removed.
Using these and other appliances allows orthodontists to customize treatment to an individual patient’s particular malocclusion. With the right anchor, even the most complex bite problem can be transformed into a beautiful and healthy smile.

When your braces finally come off, you’ll hopefully be astounded by what you see –once-crooked teeth replaced by a more attractive smile. But you might also see something you didn’t expect: noticeable white spots on some of your teeth.
These spots called white spot lesions (WSLs) appear lighter than the surrounding tooth enamel due to mineral loss just beneath the surface. This happens because bacterial or food acids have contacted the enamel surface for too long and dissolved the underlying calcium and other minerals. This results in a small discolored and chalky-like area in the enamel.
WSLs are common during orthodontics because wires and brackets create hard to reach places for brushing and flossing, which can accumulate bacterial plaque. The bacteria produce acid, which weakens the enamel at these places. The tiny white spots that result are more than just unattractive—they can become entry points into the tooth for decay. That’s why they should be dealt with as soon as possible—and preferably before they’re created.
To that end, you’ll need to do as thorough a job as possible brushing and flossing while undergoing orthodontic treatment. To improve your thoroughness try using an interproximal toothbrush that can maneuver more closely around braces hardware than a regular brush. You can also improve your flossing with a floss threader or a water flosser, a device that sprays pressurized water to loosen and flush away plaque.
If you do develop WSLs, there are some things we can do to treat them. We can attempt to re-mineralize the affected enamel with the help of topical fluoride (either pastes or gels for home use or with an office application) or a re-mineralizing agent. We can also use techniques like microabrasion, which restores damaged areas beneath the surface, or inject a liquid, tooth-colored resin beneath the WSL’s surface to improve appearance and protect against decay.
If while wearing braces you do notice any white spots or other tooth discoloration let your dentist or orthodontist know right away. The sooner your dental providers can begin dealing with potential WSLs the better your chances for a healthy and beautiful outcome after braces.

Mayim Bialik has spent a good part of her life in front of TV cameras: first as the child star of the hit comedy series Blossom, and more recently as Sheldon Cooper’s love interest — a nerdy neuroscientist — on The Big Bang Theory. (In between, she actually earned a PhD in neuroscience from UCLA…but that’s another story.) As a child, Bialik had a serious overbite — but with all her time on camera, braces were just not an option.
“I never had braces,” she recently told Dear Doctor – Dentistry & Oral Health magazine. “I was on TV at the time, and there weren’t a lot of creative solutions for kids who were on TV.” Instead, her orthodontist managed to straighten her teeth using retainers and headgear worn only at night.
Today, there are several virtually invisible options available to fix orthodontic issues — and you don’t have to be a child star to take advantage of them. In fact, both children and adults can benefit from these unobtrusive appliances.
Tooth colored braces are just like traditional metal braces, with one big difference: The brackets attached to teeth are made from a ceramic material that blends in with the natural color of teeth. All that’s visible is the thin archwire that runs horizontally across the teeth — and from a distance it’s hard to notice. Celebs like Tom Cruise and Faith Hill opted for this type of appliance.
Clear aligners are custom-made plastic trays that fit over the teeth. Each one, worn for about two weeks, moves the teeth just a bit; after several months, you’ll see a big change for the better in your smile. Best of all, clear aligners are virtually impossible to notice while you’re wearing them — which you’ll need to do for 22 hours each day. But you can remove them to eat, or for special occasions. Zac Efron and Katherine Heigl, among others, chose to wear clear aligners.
Lingual braces really are invisible. That’s because they go behind your teeth (on the tongue side), where they can’t be seen; otherwise they are similar to traditional metal braces. Lingual braces are placed on teeth differently, and wearing them often takes some getting used to at first. But those trade-offs are worth it for plenty of people. Which celebs wore lingual braces? Rumor has it that the list includes some top models, a well-known pop singer, and at least one British royal.
So what’s the best way to straighten your teeth and keep the orthodontic appliances unnoticeable? Just ask us! We’d be happy to help you choose the option that’s just right for you. You’ll get an individualized evaluation, a solution that fits your lifestyle — and a great-looking smile!

The primary goal of dental care is to preserve teeth. But there are circumstances in which removing a tooth, even a relatively healthy one, could prove best in the long run.
A malocclusion (poor bite) related to crowding might fit such a circumstance. Crowding occurs when the size of the jaw is too small for the teeth coming in. With not enough space, some teeth could erupt out of their proper positions. Removing certain teeth frees up space to eventually allow braces or other orthodontic devices to re-align the teeth.
The teeth most frequently removed are the first bicuspids, located between the cuspid (the "eyeteeth" directly under the eyes) and the back teeth, and the second premolar. Removing these won't normally affect appearance or functionality once orthodontic or cosmetic treatments are complete.
Because of the mechanics of jaw development it might be necessary to perform these extractions several years before orthodontic treatment. This could create another potential problem: the time lag could adversely affect bone health.
This is because bone, as living tissue, has a life cycle with cells forming, functioning and then dissolving, and new cells taking their place. When teeth are chewing or in contact with each other they generate force that travels through the tooth roots to the bone and stimulates cell growth at a healthy replacement rate.
But when a tooth is missing, so is this stimulation. This slows the replacement rate and eventually leads to decreased bone volume. Too much bone loss could create obstacles for orthodontic treatment or a future dental implant.
To avoid this, the dentist will often place a bone graft with processed bone mineral within the empty tooth socket right after extraction. The graft serves as a scaffold for bone cells to grow upon. The graft (plus any other added growth boosters) can help maintain a healthy level of bone volume to facilitate future orthodontic or restorative treatments.
Since targeted extraction for orthodontics is time-sensitive, you should have your child's bite evaluated by an orthodontist by age 7 to see if any action is necessary. The earlier a malocclusion is detected, the more likely a more attractive and healthy smile will be the ultimate outcome.

At any given time some 4 million teens and pre-teens are wearing braces or other orthodontic appliances to correct a malocclusion (poor bite). While most cases are straightforward, some have difficulties that increase treatment time and cost.
But what if you could reduce some of these difficulties before they fully develop? We often can through interceptive orthodontics.
This growing concept involves early orthodontic treatment around 6 to 10 years of age with the goal of guiding the development of a child’s jaws and other mouth structures in the right direction. These early years are often the only time of life when many of these treatments will work.
For example, widening the roof of the mouth (the palate) in an abnormally narrow upper jaw takes advantage of a gap in the bone in the center of the palate that doesn’t fuse until later in adolescence. A device called a palatal expander exerts outward pressure on the back teeth to influence the jawbone to grow out. New bone fills in the gap to permanently expand the jaw.
In cases with a developing overbite (the upper front teeth extending too far over the lower teeth when closed), we can install a hinged device called a Herbst appliance to the jaws in the back of the mouth. The hinge mechanism coaxes the lower jaw to develop further forward, which may help avoid more extensive and expensive jaw surgery later.
Interceptive treatments can also be fairly simple in design like a space retainer, but still have a tremendous impact on bite development. A space maintainer is often used when a primary (“baby”) tooth is lost prematurely, which allows other teeth to drift into the empty space and crowd out the incoming permanent tooth. The wire loop device is placed within the open space to prevent drift and preserve the space for the permanent tooth.
To take advantage of these treatments, it’s best to have your child’s bite evaluated early. Professional organizations like the American Association of Orthodontists (AAO) recommend a screening by age 7. While it may reveal no abnormalities at all, it could also provide the first signs of an emerging problem. With interceptive orthodontics we may be able to correct them now or make them less of a problem for the future.
