Allergic reactions aren't necessarily bad: they're your body's responses to possible threats from foreign substances. But the response can go too far and cause a reaction as minor as a skin rash or as life-threatening as a multi-system shutdown called anaphylaxis.
Anything can cause an allergy: animal fur, food, chemicals — or metals. Because metals play such a large role in dental care, it's only natural we're alert to the possibility of allergic reactions from a procedure.
But don't postpone your implants or other dental work just yet — the threat isn't nearly that ominous. Here are a few facts about dental metal allergies to help you sort it out.
Allergic reactions are rare for metals used in medical and dental procedures. Although reactions to metals in joint replacements or coronary stents leading to failure do happen, actual occurrences are rare. Most metal allergies manifest as a skin reaction to jewelry or clothing. It's less likely with medical or dental metals because they're chosen specifically for their compatibility with living tissue.
Amalgam fillings account for most dental work reactions. Dentists have used this multi-metal alloy for fillings and other restorations for well over a century. Tooth-colored resins are now used for most fillings, but amalgam is still used in less visible back teeth. It's very rare for a person to experience a reaction to amalgam, but when it does occur it usually results in minor inflammation or a rash.
Implant titanium isn't just bio-compatible — it's also osteophilic. Titanium is the perfect choice for implants not only because it's tissue friendly, but also because it's bone friendly (osteophilic). Once implanted in the jaw, bone cells naturally grow and adhere to it to create a more durable bond. Not only does the body usually tolerate titanium, it welcomes it with open arms!
While it's still possible for you to have an allergy to implant titanium, the chances are remote. In one recent study involving 1,500 implant patients, titanium allergies occurred in less than 1%. So the chances are high a metal allergy won't stop you from obtaining a smile-transforming restoration with dental implants.

Tooth decay is one of the world's most prevalent diseases — and one of the most preventable. We've known the primary prevention recipe for decades: brushing and flossing daily, and dental cleanings and checkups at least twice a year.
But consistent oral hygiene isn't enough — you should also pay attention to your overall health, diet and lifestyle habits. Each of these areas in their own way can contribute to abnormally high mouth acid, which can soften enamel and open the door to tooth decay.
Lower saliva production is one such problem that can arise due to issues with your health. Among its many properties, saliva neutralizes acid and helps maintain the mouth's optimum neutral pH level. But some health conditions or medications can reduce saliva flow: less saliva means less neutralization and chronic acidity.
You can also inhibit saliva flow with one particular lifestyle habit — smoking. Tobacco smoke can damage salivary glands. Nicotine, tobacco's active ingredient, constricts blood vessels, leading to fewer antibodies delivered by the blood stream to mouth tissues to fight disease.
A diet heavy on acidic foods and beverages can also increase mouth acidity. It's not only what you're eating or drinking — it's also how often. If you're constantly snacking or sipping on something acidic, saliva doesn't have a chance to complete the neutralizing process.
In addition to your daily oral hygiene practice, you should also make changes in these other areas to further lower your risk of tooth decay. If you're taking medications that cause dry mouth, see if your doctor can prescribe a different one or try using products that stimulate saliva. Quit smoking, of course, as much for your mouth as for the rest of your health.
On the dietary front, reduce your intake of acidic foods and beverages, especially sodas, energy or sports drinks. If you've counted on the latter for hydration, switch to water instead. And limit acidic foods to mealtime rather than throughout the day.
It's all about maintaining a healthy pH level in your mouth. Doing so along with good oral hygiene will help you better avoid destructive tooth decay.

Enamel — that tough, outermost tooth layer — protects your teeth from all sorts of hazards, from bacterial attack to temperature extremes. But although the hardest substance in the human body, enamel has a mortal enemy — acid. High acid levels can cause the minerals in enamel to dissolve, a process called de-mineralization. And although saliva can neutralize these levels in approximately 45-60 minutes and restore some of the enamel’s lost minerals, a constant acidic environment can overwhelm this natural mechanism.
That’s why you should be careful with the amount and frequency of acidic foods and drinks like citrus fruits or coffee. You should be especially concerned about your intake of sodas, energy drinks or sports drinks. The latter in particular are designed to replace fluids and nutrients during intense exercise or sports events, but are often consumed as a regular beverage. And all these drinks mentioned are often sipped on throughout the day, resulting in a constant wash of acid in your mouth that can interrupt the protective response of saliva.
There’s one other source for high mouth acidity that comes not from outside the body but from within. GERD — Gastro Esophageal Reflux Disease — is a condition in which digestive acid refluxes (flows back) into the esophagus. While chronic acid reflux can damage the lining of the esophagus and lead to ulcers or even cancer, it may also pose a danger to teeth if the acid regularly rises into the mouth. Individuals encountering this will know it by the awful, acrid taste of vomit in their mouth.
To reduce the chances of high mouth acid due to food intake, limit the consumption of acidic foods and beverages to meal times and sports drink consumption to strenuous exercise or sporting events. Better yet, consider the greatest hydrator of all, water — with a neutral pH of 7.
If you’re experiencing chronic heartburn or other GERD symptoms, make an appointment to see your primary care doctor or a gastroenterologist as soon as possible. Many treatments are effective and will not only improve your general health but may also help preserve your tooth enamel.
