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.

Fans of the legendary rock band Steely Dan received some sad news a few months ago: Co-founder Walter Becker died unexpectedly at the age of 67. The cause of his death was an aggressive form of esophageal cancer. This disease, which is related to oral cancer, may not get as much attention as some others. Yet Becker's name is the latest addition to the list of well-known people whose lives it has cut short—including actor Humphrey Bogart, writer Christopher Hitchens, and TV personality Richard Dawson.
As its name implies, esophageal cancer affects the esophagus: the long, hollow tube that joins the throat to the stomach. Solid and liquid foods taken into the mouth pass through this tube on their way through the digestive system. Worldwide, it is the sixth most common cause of cancer deaths.
Like oral cancer, esophageal cancer generally does not produce obvious symptoms in its early stages. As a result, by the time these diseases are discovered, both types of cancer are most often in their later stages, and often prove difficult to treat successfully. Another similarity is that dentists can play an important role in oral and esophageal cancer detection.
Many people see dentists more often than any other health care professionals—at recommended twice-yearly checkups, for example. During routine examinations, we check the mouth, tongue, neck and throat for possible signs of oral cancer. These may include lumps, swellings, discolorations, and other abnormalities—which, fortunately, are most often harmless. Other symptoms, including persistent coughing or hoarseness, difficulty swallowing, and unexplained weight loss, are common to both oral and esophageal cancer. Chest pain, worsening heartburn or indigestion and gastroesophageal reflux disease (GERD) can also alert us to the possibility of esophageal cancer.
Cancer may be a scary subject—but early detection and treatment can offer many people the best possible outcome. If you have questions about oral or esophageal cancer, call our office or schedule a consultation. You can learn more in the Dear Doctor magazine article “Oral Cancer.”
After ruling out other possibilities for your constant jaw joint pain, your doctor has diagnosed you with a temporomandibular disorder (TMD). Now that you know what you have, what can you do about it?
Unfortunately, it's not always an easy answer. Ideas about treatment are almost as numerous as theories on the causes of TMD. By and large, though, we can classify treatment into two broad categories: conservative and aggressive.
The conservative approach is the result of many years of experimentation and application; it's also much less invasive than aggressive treatments. For most patients, though, these treatments can offer significant relief from pain and dysfunction.
Conservative treatments are based primarily on the philosophy that the temporomandibular joint is like any other joint, and should be treated that way. Treatments include thermal therapies like ice or heat packs applied to the jaw, physical therapy (gentle stretching, jaw exercise, and massage) and pain and muscle relaxant medication. In cases where teeth grinding may be a contributing factor, we might recommend a bite guard worn in the mouth to reduce biting pressure.
On the other end of the spectrum are treatments like altering the bite or the position of the jaw. The purpose of bite alteration is to change the dynamic when the jaws are in contact during chewing or clenching, and reduce pressure on the joints. This is often done by reshaping the teeth's biting surfaces, moving the teeth with orthodontics or performing crown and bridgework. Another possibility, actually modifying the lower jaw location, requires surgery. All of these aggressive treatments are done in order of less to more invasiveness.
These more aggressive treatments, especially jaw surgery, are irreversible. Furthermore, studies on results have not been encouraging — there's no guarantee you'll receive relief from your symptoms. You should consider the aggressive approach only as a last resort, after you've tried more conservative measures. Even then, you should get a second opinion before undergoing more invasive procedures.
Hopefully, you'll see relief from therapies that have made a significant difference for most TMD sufferers. And that's our goal: to reduce your pain and dysfunction and help you regain your quality of life.

November is National Diabetes Month—a time to focus on a disease that affects more than 400 million people around the world. What does diabetes have to do with oral health? Plenty! Here's a true-or-false quiz to test your knowledge on this important topic.
TRUE OR FALSE:
1. Diabetes and gum disease are connected.
TRUE. Studies have found a clear association between diabetes and gum (periodontal) disease, especially when diabetes is not well controlled. People with poorly controlled diabetes have a more severe inflammatory response to the bacteria that cause gum disease. While inflammation is normally a protective reaction of the body's immune system, too much inflammation can actually make the condition worse. In the case of gum disease, the reverse is also true: Untreated gum disease can worsen blood sugar levels in people with diabetes. The good news is that treatment of periodontal disease has been shown to improve blood sugar control.
2. People with diabetes can't have dental implants.
FALSE. Research has shown that dental implants can be a very successful tooth-replacement treatment for people with diabetes. But again, blood sugar control can be a factor. Dental implants are titanium posts that serve as artificial tooth roots. Minor surgery is required to insert an implant into the bone beneath the gums; a realistic-looking dental crown is later attached to it so it can look and function like a natural tooth. Studies have shown that it takes longer for the bone to heal around implants in people with poorly controlled diabetes. That doesn't make implant treatment impossible, but it does mean that it may be managed differently. For example, an implant may be allowed to heal for a longer period of time before a crown is attached to it.
3. People with diabetes can't do anything to improve their oral health.
FALSE. People with diabetes can have a very positive impact on their oral heath, by doing their best to control blood sugar levels with a healthy diet and exercise, and by sticking to an effective daily oral hygiene routine. This includes brushing twice a day for two minutes each time, and flossing at least once each day to remove bacterial plaque between teeth. Regular dental checkups and cleanings are also essential—not just for people with diabetes, but for everyone!

Nothing grabs your attention like a sharp tooth pain, seemingly hitting you out of nowhere while you’re eating or drinking. But there is a reason for your sudden agony and the sooner you find it out, the better the outcome for your oral health.
To understand tooth sensitivity, we need to first look at the three layers of tooth anatomy. In the center is the pulp filled with blood vessels and nerve bundles: it’s completely covered by the next layer dentin, a soft tissue filled with microscopic tubules that transmit sensations like pressure or temperature to the pulp nerves.
The third layer is enamel, which completely covers the crown, the visible part of a tooth. Enamel protects the two innermost tooth layers from disease and also helps muffle sensations so the tooth’s nerves aren’t overwhelmed. The enamel stops at about the gum line; below it the gums provide similar protection and sensation shielding to the dentin of the tooth roots.
Problems occur, though, when the dentin below the gums becomes exposed, most commonly because of periodontal (gum) disease. This bacterial infection caused by dental plaque triggers inflammation, which over time can weaken gum tissues and cause them to detach and shrink back (or recede) from the teeth. This can leave the root area vulnerable to disease and the full brunt of environmental sensations that then travel to the nerves in the pulp.
Tooth decay can also create conditions that cause sensitivity. Decay begins when certain oral bacteria multiply and produce higher than normal levels of acid. The acid in turn dissolves the enamel’s mineral content to create holes (cavities) that expose the dentin. Not treated, the infection can eventually invade the pulp, putting the tooth in danger of being lost unless a root canal treatment is performed to remove the infection and seal the tooth from further infection.
So, if you begin experiencing a jolt of pain while eating or drinking hot or cold foods or beverages, see your dentist as soon as possible to diagnose and treat the underlying cause. And protect your teeth from dental disease by practicing daily brushing and flossing, as well as seeing your dentist for regular dental cleanings and checkups. Don’t ignore those sharp pains—your teeth may be trying to tell you something.
