There are an assortment of techniques and treatments in an orthodontist's toolkit, braces being the most common and best known. Of course, there wouldn't be any tools at all if teeth couldn't move naturally.
Teeth aren't directly connected to the jawbone. An elastic tissue called the periodontal ligament lies between each one, with tiny fibers attaching to the tooth on one side and to the bone on the other. The ligament's elasticity and other qualities allow micro-movements of the teeth as we bite.
The ligament can also adapt to changes in the mouth and teeth by allowing the teeth to move to different positions. That's the basic concept behind braces: we thread a thin wire through brackets attached to the teeth, which we then attach to anchor points (usually back teeth not intended to move) and apply tension to it. Gradually over time, the target teeth move.
But what if your malocclusion (poor bite) is more complicated or the back teeth can't supply enough anchorage for moving the intended teeth? That's where we take advantage of other sources of anchorage.
One such source is the patient's skull, which we can make use of through special headgear worn a few hours a day. The device consists of a strap under tension that runs around the back of the head or neck to a wire housing attached to brackets on the target teeth. If you want to “pull” the teeth forward, the strap would come over the chin, forehead or a combination of both.
We may sometimes want to isolate some teeth to move without moving nearby teeth, such as moving front teeth backward to close a space without affecting teeth further to the rear. We can create a separate anchor point in the jaw with a TAD or temporary anchorage device.
TADs are tiny screws made of stainless steel inserted temporarily into the bone. We loop an elastic band over the TAD on one end and to a bracket or tension wire attached to the target teeth on the other. When we've achieved the teeth's new position we can easily remove the TAD from the bone.
These various tools make it possible to correct difficult or complex malocclusions. They may not always look attractive, but they'll help ensure the final result is.

Cancer treatment can be an all-out battle with intense side effects for your entire body. One particular area that can suffer is your mouth.
Chemotherapy and radiation target and destroy cancer cells, which can lead to non-cancerous cells caught in the crossfire and also destroyed. The salivary glands in the mouth are prone to such damage, which could greatly impact your ability to ward off dental disease.
Saliva, what salivary glands produce, plays a major role in oral health. The bodily fluid disseminates antibodies throughout the mouth that fight disease-causing bacteria. It also neutralizes acid, which can erode tooth enamel, and helps restore lost minerals to the enamel.
If the salivary glands become damaged, however, they may produce less saliva and create a condition called xerostomia or “dry mouth.” This is a common occurrence for cancer patients, which can rob them of saliva’s benefits and make them more susceptible to tooth decay or periodontal (gum) disease. The end result could be tooth loss.
There are things you and your dentist can do to prevent this. First, have a complete dental checkup before undergoing cancer treatment. If at all possible have any necessary dental work undertaken (with adequate recovery time afterward) before beginning chemo or radiation. Your dentist and oncologist (cancer specialist) may need to coordinate any planned dental work.
You should also practice daily oral hygiene with brushing and flossing, along with keeping up your regular dental cleanings. This will prevent the buildup on teeth of bacterial plaque, which in turn will reduce your chances for dental disease. Your dentist may also prescribe antibacterial as well as fluoride mouth rinses to help limit the growth of oral bacteria.
To minimize dry mouth, increase your water consumption as much as possible. You may also use saliva boosters like xylitol, an alcohol-based sweetener found in many gums or mints that promotes salivation (it also deters oral bacterial growth).
And don’t forget to maintain a healthy diet, which will not only benefit your stamina during cancer treatment but can also help you maintain better dental health. Providing good care for your mouth during this trying time will help ensure your teeth and gums stay as healthy as possible.

A loose permanent tooth is not a good thing—and not something you should put off having examined. That’s because a loose tooth could soon become a lost tooth.
How we treat it depends on its underlying cause, which could be one of two types. One is primary occlusal trauma, meaning the affected tooth has experienced accidental trauma or higher biting forces than it normally encounters. This usually happens because of teeth grinding habits.
It could also be secondary occlusal trauma. Unlike primary trauma where the supporting gums and bone may be reasonably healthy, secondary trauma occurs because these structures have been severely damaged by periodontal (gum) disease. As the gums begin to detach from a tooth and its underlying bone deteriorates, even normal biting forces can loosen it.
If gum disease is present, our first priority is to bring it under control. We do this primarily by removing all dental plaque (a thin film of bacteria and food particles that triggers the infection and sustains it) and calculus or tartar (calcified plaque). This can take several sessions and, in the case of deep infection, may require a surgical procedure.
On the other hand, if teeth grinding is the primary cause, we’ll focus on minimizing the habit and its effects. One way is to create a custom-fitted guard worn to prevent upper and lower teeth from making solid contact. You may also need to improve your management of stress—another factor in teeth grinding—through medication, therapy or biofeedback.
In either case, improved periodontal health will help the gums naturally regain their strong attachment with help, if necessary, from gum tissue or bone grafting surgery. But this healing process can take time, so we may need to secure a loose tooth in the interim by splinting it to neighboring stable teeth. This usually requires bonding rigid material or metal across the back of all involved teeth or in a channel cut along the teeth’s biting surfaces. In this way the more stable teeth support the loose one.
Splinting may be temporary as the mouth heals from disease or trauma and the teeth regain their stability. In some cases, though, it may be permanent. Either way, dealing promptly with a loose tooth can help ensure it’ll survive—so see your dentist as soon as possible.
