The subject of allergies covers a wide swath in medicine. Among other things, people have allergic reactions to animal fur, various foods and plant pollen. The effects are equally wide-ranging, anything from a mild rash to anaphylaxis, a life-threatening shutdown of the body's vital systems.
Approximately 5% of people are also allergic to various metals including nickel, cobalt, chromium and gold. Reactions to metal can occur when an allergic person comes in contact with items like jewelry, clothing or even mobile phones. There's even a chance of a metal allergy reaction from certain kinds of dental work.
It's unlikely, though, that you should be concerned if you're considering dental treatment or cosmetic work to upgrade your smile. Although allergic reactions like inflammation or a rash have been known to occur with amalgam “silver” fillings, it's quite rare. It's even less of a concern since “tooth-colored” materials for fillings are now outpacing the use of amalgam fillings, which are used in out-of-sight back teeth.
Of course, metal is used for other dental treatments besides fillings, including the most popular of tooth replacement systems, dental implants. An implant is essentially a metal post, usually made of pure titanium or a titanium alloy, which is imbedded into the jawbone. Even so, there's little chance you'll develop an allergic reaction to them.
For one thing, titanium is highly prized in both medical and dental treatments because of its biocompatibility. This means titanium devices like prosthetic joints and implants won't normally disrupt or cause reactions with human tissue. Titanium is also osteophilic: Bone cells readily grow and adhere to titanium surfaces, a major reason for dental implants' long-term durability.
That's not to say titanium allergies don't exist, but their occurrence is very low. One recent study detected a titanium allergy in only 0.6% of 1,500 implant patients who participated.
At worst, you may need to consider a different type of tooth replacement restoration in the rare chance you have a titanium allergy. More than likely, though, you'll be able obtain implants and enjoy the transformation they can bring to your smile.

The monarchs of the world experience the same health issues as their subjects—but they often tend to be hush-hush about it. Recently, though, the normally reticent Queen Elizabeth II let some young dental patients in on a lesser known fact about Her Majesty's teeth.
While touring a new dental hospital, the queen told some children being fitted for braces that she too “had wires” once upon a time. She also said, “I think it's worth it in the end.”
The queen isn't the only member of the House of Windsor to need help with a poor bite. Both Princes William and Harry have worn braces, as have other members of the royal family. A propensity for overbites, underbites and other malocclusions (poor bites) can indeed pass down through families, whether of noble or common lineage.
Fortunately, there are many ways to correct congenital malocclusions, depending on their type and severity. Here are 3 of them.
Braces and clear aligners. Braces are the tried and true way to straighten misaligned teeth, while the clear aligner method—removable plastic mouth trays—is the relative “new kid on the block.” Braces are indeed effective for a wide range of malocclusions, but their wires and brackets make it difficult to brush and floss, and they're not particularly attractive. Clear aligners solve both of these issues, though they may not handle more complex malocclusions as well as braces.
Palatal expanders. When the upper jaw develops too narrowly, a malocclusion may result from teeth crowding into too small a space. But before the upper jaw bones fuse together in late childhood, orthodontists can fit a device called a palatal expander inside the upper teeth, which exerts gentle outward pressure on the teeth. This encourages more bone growth in the center to widen the jaw and help prevent a difficult malocclusion from forming.
Specialized braces for impacted teeth. An impacted tooth, which remains partially or completely hidden in the gums, can impede dental health, function and appearance. But we may be able to coax some impacted teeth like the front canines into full eruption. This requires a special orthodontic technique in which a bracket is surgically attached to the impacted tooth's crown. A chain connected to the bracket is then looped over other orthodontic hardware to gradually pull the tooth down where it should be.
Although some techniques like palatal expanders are best undertaken in early dental development, people of any age and reasonably good health can have a problem bite corrected with other methods. If you are among those who benefit from orthodontics, you'll have something in common with the Sovereign of the British Isles: a healthy, attractive and straighter smile.
Each year, millions of children and teenagers wear braces or clear aligners to straighten a crooked smile. But there may be a way to treat some of these bite problems and avoid braces—by intercepting the problem at an earlier age.
This can often be done if the bite problem stems from abnormal jaw development rather than misaligned teeth. An example of this occurs when the upper jaw growth outpaces the lower jaw, causing the upper teeth to protrude beyond the lower teeth. Aside from the effect on appearance, protruding front upper teeth may extend beyond the protection of the lip and be more prone to injury.
A device called a Herbst appliance could prevent this from happening. The top of the device has two hinged metal tubes that connect to elastic bands bonded to the back teeth on both sides of the upper jaw. The bottom also has tubes affixed in the same way to the bottom teeth, except they're slightly smaller and fit within the upper tubes.
The lower tubes sliding within the upper tubes produces slight pressure against the lower jaw to ease it forward. This gradually influences the lower jaw to grow at a pace equal with the upper jaw to decrease the chances of poor bite development. Unlike other corrective methods, the Herbst appliance fixed in place and out of the way won't interfere with sports or other physical activities.
An installed Herbst appliance may change a patient's sensations during swallowing, eating or speaking, but most children adapt to the changes within a few days. And, because the device can create challenges for keeping the back teeth clean, many dentists recommend adding a fluoride rinse to daily brushing and flossing as an added boost against tooth decay.
The Herbst appliance is most effective during the period of most rapid physical growth between the ages of 11 and 14, but if the teeth are already beginning to protrude it can be undertaken as early as 8 or 9. Either way, this important orthodontic tool could help address a complicated bite problem and reduce the need for more costly orthodontic treatment later on.

Each year millions of people endure repeated episodes of congestion, coughing and headaches, all the miseries that come with a sinus infection. Although it seems like all the action is occurring around the nose and upper face, the actual cause could be emanating from somewhere else—your teeth.
It can all begin with decay forming a small cavity in one of the upper back teeth. If it isn't caught and treated early, the decay can spread into the tooth pulp and root canals, tiny passageways to the root and bone. This may or may not cause a severe toothache or sensitivity as the tooth's nerves respond to the infection. These nerves, though, most often eventually die and the pain, if present, will subside—but not the infection.
Left untreated, the infection may then advance into the bone around the root tip, breaking it down and giving bacteria an entryway into the floor of the maxillary sinus that rests just above the upper jaw. Here bacteria can take up residence, occasionally flaring into a sinus infection. This chronic infection could go on for years with allergies mistakenly taking the blame.
If you have frequent bouts of sinusitis, a possible dental connection may be worth investigating. And in the dental profession, there may be no better “detective” for this than an endodontist. Specializing in interior tooth problems and treatments, an endodontist has the diagnostic equipment like CT or 3-D cone beam scanning to accurately image the teeth and upper jaw. With their advanced diagnostics, they're in the best position to uncover hidden tooth decay contributing to sinus problems.
Endodontists are also skilled in treating advanced tooth decay. The main procedure is known as root canal treatment, in which the dentist drills into the tooth's interior to remove infected tissue from the pulp and root canals. They then fill these empty spaces, seal and then crown the tooth for added protection.
After treatment and following up with your physician, you may find your sinus infections are less frequent. And by promptly seeking treatment at the first sign of tooth pain or sensitivity, you might prevent chronic sinusitis from even developing.

If you're an adult, your teeth shouldn't wiggle—not even a little bit. If you have a loose tooth, you need to see your dentist as soon as possible to avoid losing it permanently.
Loose teeth usually happen because of one of two kinds of bite-related trauma. One is known as primary occlusal, which usually happens when the periodontal (gum) structures that help secure teeth encounter higher than normal biting forces. This is usually due to a clenching or grinding habit.
The other and more common kind is secondary occlusal: This happens when the periodontal structures and supporting bone are in a weakened state, usually because of gum disease. In this condition, even normal biting forces can cause damage to a tooth's gum attachment and result in looseness.
To stop a loose tooth from becoming a lost tooth, we'll need to take these immediate steps.
Treat any underlying disease. If a gum infection is the culprit, our first priority is to stop it from doing any more damage. The main treatment for gum disease is to remove dental plaque, a thin film of bacteria and food particles that's the usual cause for the infection. Depending on how much the infection has advanced, this could take several sessions to bring it under control.
Reduce abnormal biting forces. If teeth are loose from abnormally high bite forces, there are a few things we can do. One is to selectively reshape the biting surfaces of teeth so that they receive less force while biting. Another approach is to minimize the effect of teeth grinding with an occlusal guard worn in the mouth: Its slick plastic surface prevents teeth from making solid contact while biting.
Splint loose teeth to secure them. We can secure loose teeth by splinting them to more stable teeth with metal strips or other means. Splinting is often done in conjunction with the aforementioned treatments, and is usually temporary until the tooth regains its periodontal attachments. Sometimes, though, it may be necessary to permanently splint a weakened tooth.
A loose tooth isn't necessarily destined to be lost. But we'll have to act quickly—if you have a loose tooth see us as soon as possible to determine how best to save it.
