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.

If you would like more information on dental implants as a tooth replacement option, please contact us or schedule an appointment for a consultation. You can also learn more about this topic by reading the Dear Doctor magazine article “Metal Allergies to Dental implants.”

Find out whether the changes you are experiencing could be warning you of oral cancer.

While oral cancer may not get as much discussion as other cancers it certainly isn’t something to oral cancerignore. In fact, oral cancer actually has a higher death rate than other more commonly talked about cancers like Hodgkin’s lymphoma, testicular cancer and cervical cancer. Our Braintree, MA dentists are here to provide you with warning signs of oral cancer and when to visit us for care.

Oral cancer can occur anywhere in the mouth including the throat, lips, salivary glands and sinuses, just to name a few. As with any cancer or serious illness, early detection is key to having a successful and effective treatment. If you experience any of these symptoms for more than two weeks then it’s time to give our Braintree general dentist a call:

  • A lump, sore, or suspicious growth on the throat or mouth
  • Red or white lesions on your lips or in your mouth
  • Pain, tenderness or numbness anywhere in the mouth
  • Painful or difficulty chewing, speaking or swallowing

While oral cancer can happen to anyone there are some habits and lifestyle choices that can increase your risk. Using tobacco in any form, whether it’s smoking cigarettes or chewing tobacco, can increase your chances of developing oral cancer. The Mouth Cancer Foundation has reported that as many as 90 percent of those who have been diagnosed with oral cancer also use tobacco. Heavy drinkers are also at an increased risk.

Age and nutrition also play a role. Those over the age of 40 are at an increased risk of developing oral cancer, and those whose diets lack nutrients found in fruits and vegetables are also more likely to develop this form of cancer.

Fortunately, oral cancer screenings are easy, fast and painless. We can even perform them at your next dental exam! It only takes a few minutes to examine your mouth to check for suspicious growths or symptoms that could be indicative of cancer. Any suspicious lumps or growths will be biopsied and tested for cancer.

If you are noticing a suspicious growth or lump, or any changes to your oral health, then it’s time to call Dr. George Salem and Associates in Braintree, MA right away.


Are bleeding gums something you should be concerned about? Dear Doctor magazine recently posed that question to Dr. Travis Stork, an emergency room physician and host of the syndicated TV show The Doctors. He answered with two questions of his own: “If you started bleeding from your eyeball, would you seek medical attention?” Needless to say, most everyone would. “So,” he asked, “why is it that when we bleed all the time when we floss that we think it’s no big deal?” As it turns out, that’s an excellent question — and one that’s often misunderstood.

First of all, let’s clarify what we mean by “bleeding all the time.” As many as 90 percent of people occasionally experience bleeding gums when they clean their teeth — particularly if they don’t do it often, or are just starting a flossing routine. But if your gums bleed regularly when you brush or floss, it almost certainly means there’s a problem. Many think bleeding gums is a sign they are brushing too hard; this is possible, but unlikely. It’s much more probable that irritated and bleeding gums are a sign of periodontal (gum) disease.

How common is this malady? According to the U.S. Centers for Disease Control, nearly half of all  Americans over age 30 have mild, moderate or severe gum disease — and that number increases to 70.1 percent for those over 65! Periodontal disease can occur when a bacteria-rich biofilm in the mouth (also called plaque) is allowed to build up on tooth and gum surfaces. Plaque causes the gums to become inflamed, as the immune system responds to the bacteria. Eventually, this can cause gum tissue to pull away from the teeth, forming bacteria-filled “pockets” under the gum surface. If left untreated, it can lead to more serious infection, and even tooth loss.

What should you do if your gums bleed regularly when brushing or flossing? The first step is to come in for a thorough examination. In combination with a regular oral exam (and possibly x-rays or other diagnostic tests), a simple (and painless) instrument called a periodontal probe can be used to determine how far any periodontal disease may have progressed. Armed with this information, we can determine the most effective way to fight the battle against gum disease.

Above all, don’t wait too long to come in for an exam! As Dr. Stork notes, bleeding gums are “a sign that things aren’t quite right.”  If you would like more information about bleeding gums, please contact us or schedule an appointment. You can read more in the Dear Doctor magazine article “Bleeding Gums.” You can read the entire interview with Dr. Travis Stork in Dear Doctor magazine.
