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.

When the multi-platinum recording artist, songwriter and TV personality Jason Derulo was recently asked about his ideal woman, his answer covered a remarkably broad spectrum. "There’s no specific thing," he said, "so I think it’s unfair to say what my ‘type’ is." But it turns out that there is one thing the So You Think You Can Dance judge considers essential: A beautiful smile.
"I’m not into messy teeth," Derulo said. "If the grill has spaces and different colors, it’s not my vibe."
As it turns out, he may be on to something: A number of surveys have indicated that a bright, healthy smile is often the first thing people notice when meeting someone new. Yet many are reluctant to open up that big grin because they aren’t satisfied with the way their teeth look. If you’re one of them, consider this: Modern cosmetic dentistry offers a variety of ways to improve your smile — and it may be easier and more affordable than you think.
For example, if your smile isn’t as bright as you would like it to be, teeth whitening is an effective and economical way to lighten it up. If you opt for in-office treatments, you can expect a lightening effect of up to 10 shades in a single one-hour treatment! Or, you can achieve the same effect in a week or two with a take-home kit we can custom-make for you. Either way, you’ll be safe and comfortable being treated under the supervision of a dental professional — and the results can be expected to last for up to two years, or perhaps more.
If your teeth have minor spacing irregularities, small chips or cracks, it may be possible to repair them in a single office visit via cosmetic bonding. In this process, a liquid composite resin is applied to the teeth and cured (hardened) with a special light. This high-tech material, which comes in colors to match your teeth, can be built up in layers and shaped with dental instruments to create a pleasing, natural effect.
If your smile needs more than just a touch-up, dental veneers may be the answer. These wafer-thin coverings, placed right on top of your natural teeth, can be made in a variety of shapes and colors — from a natural pearly luster to a brilliant "Hollywood white." Custom-made veneers typically involve the removal of a few millimeters of tooth enamel, making them a permanent — and irreversible — treatment. However, by making teeth look more even, closing up spaces and providing dazzling whiteness, veneers just might give you the smile you’ve always wanted.
