Braces utilize the mouth’s existing teeth-moving mechanism by applying pressure in the direction of the desired movement. This is done with a wire laced through metal brackets affixed to the outside of the teeth that’s then usually anchored to brackets on the back teeth to maintain constant tension.
This anchorage set-up alone, however, may not work effectively with all bite situations, which might require other points of anchorage. That’s where these other tools in the orthodontist’s toolkit can come in handy.
Headgear. These appliances not only aid with moving teeth but they also help influence the proper growth of facial structures (as when one of the jaws is too far forward or too far back). Because of this influence on jaw growth you’ll only find them used with pre-teens. The most typical application is a strap running around the back of the head or neck (or sometimes over the chin or forehead) that attaches in the front to brackets usually bonded to the molars. In this case the back of the patient’s skull serves as the anchor point.
Temporary anchorage devices (TADs). Orthodontists sometimes wish to isolate the teeth to be moved from nearby teeth that shouldn’t be. For example, they may want to move front teeth back to close a space without the back teeth moving forward. In this case, it may be necessary to create a separate anchorage point in the jaw. This can be done with TADs, which are made of either biotolerant (stainless steel, chromiumâ??cobalt alloy), bioinert (titanium, carbon), or bioactive (hydroxyapatite, ceramic oxidized aluminum) materials and shaped like mini-screws. Orthodontists insert them into the bone and then attach them to the braces using elastics (rubber bands). After completing orthodontic treatment they’re easily removed.
Elastics. We’ve already mentioned them, but elastics deserve their own category because they can be used in various kinds of anchorage. They play an important role, for example, in cross-arch anchorage that maintains tension between the upper and lower jaws. They can also be used to help move one or more groups of teeth — or isolate certain teeth from moving. They truly are flexible (no pun intended) in their uses for fine-tuned tooth movement.
All these devices can be used in various combinations to match and correct whatever bite situation a patient may have. The end result is straighter and better-functioning teeth — and a more attractive smile.

Whether she’s singing, dancing or acting, Jennifer Lopez is a performer who is known for giving it all she’s got. But during one show, Lopez recently admitted, she gave a bit more then she had planned.
“I chipped my tooth on stage,” she told interviewers from Entertainment Tonight, “and had to finish the show….I went back thinking ‘Can I finish the show like this?’”
With that unlucky break, J-Lo joins a growing list of superstar singers—including Taylor Swift and Michael Buble—who have something in common: All have chipped their teeth on microphones while giving a performance.
But it’s not just celebs who have accidental dental trouble. Chips are among the most common dental injuries—and the front teeth, due to their position, are particularly susceptible. Unfortunately, they are also the most visible. But there are also a number of good ways to repair chipped, cracked or broken teeth short of replacing them.
For minor to moderate chips, cosmetic bonding might be recommended. In this method, special high-tech resins, in shades that match your natural teeth, are applied to the tooth’s surface. Layers of resin, cured with a special light, will often restore the tooth to good appearance. Best of all, the whole process can often be done in just one visit to the dental office, and the results can last for several years.
For a more permanent repair—or if the damage is more extensive—dental veneers may be another option. Veneers are wafer-thin shells that cover the entire front surface of one or more teeth. Strong, durable and natural-looking, they can be used to repair moderate chips, cracks or irregularities. They can also help you get a “red-carpet” smile: brilliant white teeth with perfectly even spacing. That’s why veneers are so popular among Hollywood celebs—even those who haven’t chipped their teeth!
Fortunately, even if the tooth is extensively damaged, it’s usually possible to restore it with a crown (cap), a bridge—or a dental implant, today’s gold standard for whole-tooth replacement. But in many cases, a less complex type of restoration will do the trick.
Which tooth restoration method did J-Lo choose? She didn’t say—but luckily for her adoring fans, after the microphone mishap she went right back up on stage and finished the show.

Bad news at your last dental visit: You have a decayed tooth. And not just in the enamel—the decay has invaded the tooth's inner pulp and the resulting infection is threatening the supporting bone structure.
You're thinking that tooth is toast. Then comes the good news: your dentist believes the tooth can be rescued with a root canal treatment.
But then you begin thinking about how often Uncle Sid says he'd rather undergo a colonoscopy than have a root canal. Is the procedure really as painful and uncomfortable as popular culture says it is? What is a root canal really like?
First step: Things go numb. Uncle Sid is wrong: A root canal treatment is painless because your dentist will first make sure the entire area involving the tooth is anesthetized. This does involve injecting the local anesthetic deep within the tissues, but you won't even feel the needle prick thanks to topical anesthesia applied to the surface gums.
Second step: Drilling deep. After applying a protective dam to isolate the infected tooth from its neighbors, your dentist will drill a small access hole through the enamel and dentin to reach the pulp and root canals. If it's one of the larger back teeth, the access hole is usually drilled in the tooth's biting surface; in a front tooth, the hole is usually located on the tongue side.
Third Step: Removing diseased tissue. Using special instruments, your dentist will remove the diseased tissue in the pulp and root canals, essentially stopping the infection and any tooth pain you've been experiencing. The empty pulp chamber and canals are often then disinfected with a special antibacterial solution.
Fourth Step: Protecting the tooth. After some shaping, the pulp chamber and root canals are filled with a special filling to prevent further infection. The access hole is then filled and sealed to complete the procedure. At some point in the future, the tooth typically will need a crown to add support and further protection.
You may have some minor discomfort afterward, but this can usually be managed with a mild pain reliever like ibuprofen or acetaminophen. After a week or so, you'll be good as new—and so will your tooth.
