EvenwithMercuryDentalAmalgamisaSafeChoiceforToothFilling

One of the top concerns in public health today is exposure to the metallic element mercury within the environment. At abnormal levels, mercury can have a toxic effect on our nervous systems and cause other health problems.

These concerns over mercury have also increased attention on one material in dentistry that has included the metal in its makeup for over a century — dental amalgam for filling teeth. Amalgam is a metal alloy that can include, in addition to mercury, silver, tin, and copper. When first mixed dental amalgam is a moldable material used for fillings in prepared teeth. It then hardens into a durable restoration that can withstand biting forces.

While the use of amalgam has declined with the introduction of life-like colored fillings, it's still used for teeth like molars subject to high biting forces. With what we now know about the ill effects of mercury (which can make up to half of an amalgam mixture) is it safe to continue its use?

The American Dental Association has performed extensive research into amalgam safety. They've found that mercury is stabilized by the other metals in the amalgam. This prevents "free" molecules of mercury, the real source of harm to health, from escaping into the blood stream in the form of vapor. Although trace amounts of mercury vapor from the amalgam are released as a person chews, those levels are well below the threshold that could cause harm.

From a patient standpoint, the biggest drawback to dental amalgam isn't safety — it's the appearance of teeth it's used on. Silver fillings aren't considered attractive. And now there are viable filling alternatives that not only look like natural teeth but can withstand biting forces almost as well as amalgam. These materials include composite resins, mixtures of glass or quartz within resin, or glass and resin ionomers. Each of these has advantages and disadvantages depending on how and where they're applied.

After a thorough dental examination, we'll be able to advise you on what filling material will work best to produce the best result. And if we do suggest dental amalgam you can rest assured it will be a safe choice.

MasterIllusionistBenefitsfromtheMagicofOrthodontics

Magician Michael Grandinetti mystifies and astonishes audiences with his sleight of hand and mastery of illusion. But when he initially steps onto the stage, it’s his smile that grabs the attention. “The first thing… that an audience notices is your smile; it’s what really connects you as a person to them,” Michael told an interviewer.

He attributes his audience-pleasing smile to several years of orthodontic treatment as a teenager to straighten misaligned teeth, plus a lifetime of good oral care. “I’m so thankful that I did it,” he said about wearing orthodontic braces. “It was so beneficial. And… looking at the path I’ve chosen, it was life-changing.”

Orthodontics — the dental subspecialty focused on treating malocclusions (literally “bad bites”) — can indeed make life-changing improvements. Properly positioned teeth are integral to the aesthetics of any smile, and a smile that’s pleasing to look at boosts confidence and self-esteem and makes a terrific first impression. Studies have even linked having an attractive smile with greater professional success.

There can also be functional benefits such as improved biting/chewing and speech, and reduced strain on jaw muscles and joints. Additionally, well-aligned teeth are easier to clean and less likely to trap food particles that can lead to decay.

The Science Behind the Magic

There are more options than ever for correcting bites, but all capitalize on the fact that teeth are suspended in individual jawbone sockets by elastic periodontal ligaments that enable them to move. Orthodontic appliances (commonly called braces or clear aligners) place light, controlled forces on teeth in a calculated fashion to move them into their new desired alignment.

The “gold standard” in orthodontic treatment remains the orthodontic band for posterior (back) teeth and the bonded bracket for front teeth. Thin, flexible wires threaded through the brackets create the light forces needed for repositioning. Traditionally the brackets have been made of metal, but for those concerned about the aesthetics, they can also be made out of a clear material. Lingual braces, which are bonded to the back of teeth instead of the front, are another less visible option. The most discrete appliance is the removable clear aligner, which consists of a progression of custom-made clear trays that reposition teeth incrementally.

How’s that for a disappearing act?!
