Tooth-ColoredFillingsTrueorFalse

Do you have silver dental fillings that you wish you didn't have? Wouldn't it be nice if no one could look in your mouth and see how many cavities you had as a kid? Tooth-colored fillings may offer a solution to the problem of too much metal in your mouth. How much do you really know about non-metallic tooth-colored fillings? Take our quiz and find out.

True or false: Tooth-colored fillings are a radical new technology.

False. A variety of dental porcelains and composite resins have been successfully used in tooth restoration for many years. These materials have been designed to mimic the properties of the two major components of teeth: the hard outer enamel, and the bone-like inner dentin. Our increasing understanding of tooth structure and composition has led to better and more natural-looking filling substances.

True or false: Teeth must remain rigid under the pressure of the bite.

False. At one time, metal amalgam (silver) fillings were preferred because of their extreme hardness. But we now know that the crowns of our teeth actually flex under the forces of the bite. This discovery has spurred the development of new methods and materials to stabilize the restored tooth and reduce the incidence of premature failure.

True or false: It's usually more complicated to put in a tooth-colored filling than a metal one.

False. Regardless of which material is used, the basic process of filling a tooth is the same. The dentist prepares the tooth for treatment, removes decay, and places a filling directly into the tooth. If the filling is moderately deep, a tooth-colored filling may be set in several layers which are successively “cured” or hardened. More extensive restorations may require more than one visit, but the natural-looking results generally justify the extra time.

True or false: Regular metal fillings make the tooth structure stronger.

False. Properly securing an amalgam filling may require the tooth to be “undercut,” meaning that a greater amount of healthy tooth material must be removed. This can weaken the tooth structure, eventually leading it to chip and crack. Non-metallic fillings don't require undercutting, so more tooth structure is left intact. This more conservative treatment can result in a stronger, longer-lasting restoration.

True or false: Non-metallic (tooth-colored) fillings are safer than silver fillings.

False. While each method has advantages and disadvantages, and may not be an appropriate treatment in every situation, both methods have been deemed safe and effective by major U.S. and international science and health organizations. While there have been recent concerns about mercury in amalgam fillings, there is presently no reason to believe that it presents any cause for concern.

BracesARiteofPassageEvenforHollywoodKids

Her parents Will and Jada are Hollywood royalty, who helped her land her first acting role when she was 7. She released a hit single, “Whip My Hair,” before she had quite reached the age of 10; shortly afterward, she was signed to a record label. Yet the young singer and actress Willow Smith has at least one thing in common with plenty of ‘tweens and teens across America: She needed to wear braces to correct problems with the alignment of her teeth.

Why do braces seem to be a part of growing up for so many kids? One answer is because they work so well. Braces apply gentle pressure to the teeth through a thin, flexible wire called an archwire. Attached to the teeth with a metal or ceramic bracket, the archwire exerts a light force which causes teeth to gradually move into better positions. Sometimes, when additional force is needed, elastic bands or other appliances may be used in conjunction with braces.

Most everyone is familiar with the silvery metal “tracks” of traditional braces. But did you know that there are a number of other options too? For a more inconspicuous look, you may be able to have braces with tooth-colored ceramic brackets; then, only the thin archwire will be visible in your mouth. It’s even possible in some cases to place the metal wires and brackets on the tongue side of the teeth. With this system, called lingual braces, the orthodontic hardware is truly invisible.

What if you didn’t need metal braces at all? Some people can get good results using a system of clear plastic aligners instead of braces. The aligners are worn 23 hours a day, but can be taken off for cleaning and for important events. They work best for correcting mild or moderate alignment problems.

Still, plenty of people feel that if they’re going to wear braces, they might as well flaunt them. That’s why some types of braces are available with bands that come in different colors. When Willow’s brother Jayden wore braces, he was reported to favor red and black ones. Jayden, who is about two years older than his sister, had his braces removed just before Willow got hers put on.

So if it turns out that you need braces, remember that lots of your favorite celebrities wore them too. And keep in mind that, depending on your own situation, you may have several options to choose from.
