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.

Undergoing dental work is for the most part a pain-free affair. But once you're home and the anesthetic begins to wear off, you may have some discomfort.
Fortunately, most post-procedure pain can be managed with non-steroidal anti-inflammatory drugs or NSAIDs. And while stronger versions of these pain relievers can be prescribed, you may only need one sold over-the-counter.
NSAIDs like ibuprofen or acetaminophen work by inhibiting the release of prostaglandins, substances that stimulate inflammation in traumatized or injured tissues. It differs in this way from the two other primary pain medications: Steroids act like natural hormones that alleviate physical stress in the tissues; and narcotics like morphine or codeine suppress the brain's reaction to nerve firings.
While these stronger types are effective for stopping pain, they can have several serious side effects. Narcotics in particular can be addictive. Although they may be necessary in serious cases of acute pain, most dentists turn to non-addictive NSAIDs first, which are usually effective with the kind of discomfort associated with dental work and with fewer side effects.
That's not to say, however, that NSAIDs are risk-free—they must be taken properly or you could suffer serious health consequences. For one, NSAIDs have a blood-thinning effect that's even more pronounced when taken consistently over a period of weeks. This can lead to bleeding that is difficult to stop and erosion of the stomach lining leading to ulcers. Prolonged use can also damage the kidneys.
As a rule of thumb, adults shouldn't take more than 2400 milligrams of ibuprofen or other NSAIDs in a day, unless otherwise directed by their doctor. For most, a 400-milligram oral dose taken with food (to minimize stomach upset) is usually sufficient to relieve pain for around five hours.
You'll usually avoid unwanted health effects by keeping within your dentist's recommended doses and taking an NSAID for only a few days. Taking an NSAID properly can help keep your discomfort to a minimum after dental work without the need for stronger drugs.

What happens when you lose a tooth? In the short-run, it can certainly undermine your appearance and ability to efficiently chew and digest food. But a chain of events could also be set in motion that may cause the most harm to your appearance and health—and it all has to do with bone loss.
Our bones aren't just rigid structures providing a frame for our bodies. They're living tissue with other purposes like producing blood cells and regulating the endocrine system. Bone tissue is constantly replenishing itself as older cells die and newer ones take their place.
In the jawbone, the pressure generated by the teeth while biting and chewing travels through the roots to stimulate the growth of new bone. If a tooth goes missing, however, the bone around the tooth also loses this growth stimulus.
This can cause normal bone growth to slow so that dying bone cells aren't sufficiently replaced. The bone may then diminish at an alarming rate—a decrease in width of about 25% in the first year after a tooth loss and several millimeters in height after only a few years.
This bone loss can continue to advance, especially if multiple teeth are lost, until the jaw structure as a whole loses significant height. The bite may then collapse, forcing the front teeth to push forward. In this state, a person may not be able to adequately bite or chew food. It can also damage their appearance—their smile suffers, of course, but their entire face may also appear shrunken.
You may be able to avoid this scenario if you replace missing teeth with dental implants. In addition to their life-likeness and durability, implants can also stop or slow bone loss. This is because titanium, the principle metal used in an implant, has a strong affinity with bone: Bone cells readily grow and attach to the titanium surface and foster new growth.
But don't wait: Bone loss could eventually extend beyond what an implant can accommodate—you may then need grafting to build up the bone or consider a different type of restoration. So, speak with your dentist as soon as possible about an implant restoration for a lost tooth to help avoid significant bone loss.
