The dental implant is the closest thing in modern dentistry to a natural tooth. This is because an implant replaces more than the visible crown — it also replaces the root, thanks to a metal post imbedded in the bone.
But what if you have a metal allergy — are you out of luck replacing a tooth with an implant? Before answering this question, let's take a closer look at metal allergies.
An allergy is an overreaction of the body's immune system to a particular foreign substance. This response can be as inconsequential as a minor rash or as life-threatening as a shutdown of the body's organ systems. You can be allergic to anything, including metals.
Usually, these allergies are to specific kinds of metals. For example, about 17% of women and 3% of men are allergic to nickel, while smaller percentages are allergic to cobalt or chromium. Most allergic reactions to metal occur from external contact with jewelry or similar metal items that create rashes or other anomalies on the skin. On a more serious note, an allergy to metal in a body replacement part could result in the body rejecting it.
Metals have also played an important role in dental care, particularly dental amalgam used for tooth fillings. Dental amalgam is a mixture of a precious metal like gold or silver with other metals like copper, tin and, in small amounts, mercury. While dental amalgam has been used safely for decades, there have been rare cases of inflammation or rashes.
This brings us to dental implants and the most common metal used in them, titanium. The commercial version of this metal is highly prized in medical and dental applications because it has a special affinity with bone. Bone cells readily grow and adhere to the metal, which strengthens the bond between the implant and the jawbone.
Even if you have a rare allergy to certain metals, it's even rarer that would include titanium. In one particular study of 1,500 implant patients less than 1% reported any reaction at all.
If you're concerned, you can undergo testing to see if you react to titanium. More than likely, though, you'll be able to join the millions of other patients who have successfully restored their smiles with dental implants.

Most everyone knows that going to see your dentist for regular checkups and cleanings can help save your smile — but did you ever stop to think that it just might save your life?
That's what recently happened to 11-year-old Journee Woodard of Edmond, Oklahoma. The young girl was having a routine teeth cleaning when hygienist Rachel Stroble noticed something unusual: The whites of her eyes (her sclera) had a distinctly yellow tint. Dr. Michael Chandler, Journee’s dentist, confirmed the hygienist’s suspicions, and advised her mom to take her for further testing. The tests revealed that Journee had a tumor covering parts of her pancreas, gallbladder and liver; it could have ruptured at any moment, with devastating consequences.
The tumor was removed three days later in a 9-hour operation, and Journee is now recovering. As for her dentist, Dr. Chandler told reporters that he and his staff were just doing their jobs thoroughly. “It's hard to feel like I’m a hero,” he said (though others might disagree).
Is this a one-in-a-million case? Maybe — yet for many people, a family dentist may be the health care professional who is seen more often than any other. That can put dentists in the unique position of being able to closely monitor not only a person’s oral health, but also their overall health.
There are several reasons why that’s so. One is that most systemic diseases (such as diabetes, leukemia, and heart disease, for example) can have oral manifestations — that is, symptoms that show up in the mouth. If your dentist notices something unusual, further testing may be recommended. Dentists also regularly screen for diseases specific to the mouth — such as oral cancer, which has a much better chance of being cured when it is caught at an early stage.
But beyond checking for particular diseases, dentists often notice other things that may indicate a health issue. For example, if you complain of dry mouth or snoring, and appear fatigued in the dental chair, your dentist may suspect undiagnosed sleep apnea: a potentially serious condition. Many other signs — such as yellowed eyes, a pounding heart rate, or shortness of breath — can indicate potential problems.
Of course, we’re not even mentioning the main reason for regular dental checkups — keeping your smile healthy and bright; for many people that’s reason enough. How does Journee’s mom feel about keeping dental appointments? “I will never miss another dentist appointment,” she told reporters. “I will never reschedule.”

While the sport of golf may not look too dangerous from the sidelines, players know it can sometimes lead to mishaps. There are accidents involving golf carts and clubs, painful muscle and back injuries, and even the threat of lightning strikes on the greens. Yet it wasn’t any of these things that caused professional golfer Danielle Kang’s broken tooth on the opening day of the LPGA Singapore tournament.
“I was eating and it broke,” explained Kang. “My dentist told me, I've chipped another one before, and he said, you don't break it at that moment. It's been broken and it just chips off.” Fortunately, the winner of the 2017 Women’s PGA championship got immediate dental treatment, and went right back on the course to play a solid round, shooting 68.
Kang’s unlucky “chip shot” is far from a rare occurrence. In fact, chipped, fractured and broken teeth are among the most common dental injuries. The cause can be crunching too hard on a piece of ice or hard candy, a sudden accident or a blow to the face, or a tooth that’s weakened by decay or repetitive stress from a habit like nail biting. Feeling a broken tooth in your mouth can cause surprise and worry—but luckily, dentists have many ways of restoring the tooth’s appearance and function.
Exactly how a broken tooth is treated depends on how much of its structure is missing, and whether the soft tissue deep inside of it has been compromised. When a fracture exposes the tooth’s soft pulp it can easily become infected, which may lead to serious problems. In this situation, a root canal or extraction will likely be needed. This involves carefully removing the infected pulp tissue and disinfecting and sealing the “canals” (hollow spaces inside the tooth) to prevent further infection. The tooth can then be restored, often with a crown (cap) to replace the entire visible part. A timely root canal procedure can often save a tooth that would otherwise need to be extracted (removed).
For less serious chips, dental veneers may be an option. Made of durable and lifelike porcelain, veneers are translucent shells that go over the front surfaces of teeth. They can cover minor to moderate chips and cracks, and even correct size and spacing irregularities and discoloration. Veneers can be custom-made in a dental laboratory from a model of your teeth, and are cemented to teeth for a long-lasting and natural-looking restoration.
Minor chips can often be remedied via dental bonding. Here, layers of tooth-colored resin are applied to the surfaces being restored. The resin is shaped to fill in the missing structure and hardened by a special light. While not as long-lasting as other restoration methods, bonding is a relatively simple and inexpensive technique that can often be completed in just one office visit.
