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?!

You’re considering dental implants and you’ve done your homework: you know they’re considered the best tooth replacements available prized for durability and life-likeness. But you do have one concern — you have a metal allergy and you’re not sure how your body will react to the implant’s titanium and other trace metals.
An allergy is the body’s defensive response against any substance (living or non-living) perceived as a threat. Allergic reactions can range from a mild rash to rare instances of death due to multiple organ system shutdowns.
A person can become allergic to anything, including metals. An estimated 17% of women and 3% of men are allergic to nickel, while 1-3% of the general population to cobalt and chromium. While most allergic reactions occur in contact with consumer products (like jewelry) or metal-based manufacturing, some occur with metal medical devices or prosthetics, including certain cardiac stents and hip or knee replacements.
There are also rare cases of swelling or rashes in reaction to metal fillings, commonly known as dental amalgam. A mix of metals — mainly mercury with traces of silver, copper and tin — dental amalgam has been used for decades with the vast majority of patients experiencing no reactions. Further, amalgam has steadily declined in use in recent years as tooth-colored composite resins have become more popular.
Which brings us to dental implants: the vast majority are made of titanium alloy. Titanium is preferred in implants not only because it’s biocompatible (it “gets along” well with the body’s immune system), but also because it’s osteophilic, having an affinity with living bone tissue that encourages bone growth around and attached to the titanium. Both of these qualities make titanium a rare trigger for allergies even for people with a known metal allergy.
Still, implant allergic reactions do occur, although in only 0.6% of all cases, or six out of a thousand patients. The best course, then, is to let us know about any metal allergies you may have (or other systemic conditions, for that matter) during our initial consultation for implants. Along with that and other information, we'll be better able to advise you on whether implants are right for you.
