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.

March is national nutrition month—a good time to look at the connection between diet and oral health. You probably know that sugar is a major culprit in dental problems. This is because bacteria feed on sugars and create acid that can lead to tooth decay and gum disease. Avoiding sugary foods and drinks as much as possible is a good rule of thumb, but there are some food choices that actually benefit your oral health. Here are nutrition tips that will help keep your smile healthy for life:
Say cheese. Dairy products such as milk, cheese and yogurt contain calcium and phosphorus to build teeth and strengthen the supporting bone. And cheese neutralizes acid in the mouth to help fight cavities and gum disease.
Choose lean proteins. Lean meats, poultry, fish, milk and eggs help strengthen teeth. They are rich in protein and phosphorous, which is essential for building strong bones and teeth.
Eat a rainbow. Fruits and vegetables provide many key nutrients, including vitamins necessary for healing, bone strength, and healthy gums. Besides being nutritious, fruits and veggies scrub your teeth while you chew and stimulate the production of saliva, which is necessary for neutralizing acid and rebuilding enamel.
Nibble on nuts. Nuts contain protein, fiber and healthy fats. They also contain essential vitamins and minerals to keep teeth strong and gums healthy. Further, chewing nuts stimulates saliva production, lowering the risk of tooth decay.
Go for the grains. Studies have shown that eating too many refined carbohydrates such as white bread and sweet bakery items can lead to chronic inflammation, which is a factor in gum disease, heart disease, stroke and other conditions. In contrast, eating complex carbohydrates such as whole grains may reduce inflammation in the body.
What you put in your body can play a big role in preventing tooth decay and gum disease, so choose foods that provide the right building blocks for optimal dental and overall health.
