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.

Ashley Graham has a beautiful and valuable smile—an important asset to her bustling career as a plus-size model and television host. But she recently revealed on Instagram a “confrontation” between one of her teeth and a frozen oatmeal cookie. The cookie won.
Holding her hand over her mouth during the video until the last moment, Graham explained how she sneaked a cookie from her mom's freezer and took a bite of the frozen treat. Taking her hand from her mouth, she revealed her broken tooth.
Okay, maybe it wasn't an actual tooth that was broken: the denticle in question appeared to have been previously altered to accommodate a porcelain veneer or crown. But whatever was once there wasn't there anymore.
Although her smile was restored without too much fuss, Graham's experience is still a cautionary tale for anyone with dental work (and kudos to her for being a good sport and sharing it). Although dental work in general is quite durable, it is not immune to damage. Biting down on something hard, even as delicious as one of mom's frozen oatmeal cookies, could run you the risk of popping off a veneer or loosening a crown.
To paraphrase an old saying: Take care of your dental work, and it will take care of you. Don't use your teeth in ways that put your dental work at risk, tempting as it may be given your mouth's mechanical capabilities.
Even so, it's unwise—both for dental work and for natural teeth—to use your teeth and jaws for tasks like cracking nuts or prying open containers. You should also avoid biting into foods or substances with hard textures like ice or a rock-hard cookie from the freezer, especially if you have veneers or other cosmetic improvements.
It's equally important to clean your mouth daily, and undergo professional cleanings at least twice a year. That might not seem so important at first since disease-causing organisms won't infect your dental work's nonliving materials. But infection can wreak havoc on natural tissues like gums, remaining teeth or underlying bone that together often support dental enhancements. Losing that support could lead to losing your dental work.
And it's always a good idea to have dental work, particularly dentures, checked regularly. Conditions in the mouth can change, sometimes without you noticing them, so periodic examinations by a trained dental provider could prevent or treat a problem before it adversely affects your dental work.
We're glad Ashley Graham's trademark smile wasn't permanently harmed by that frozen cookie, and yours probably wouldn't be either in a similar situation. But don't take any chances, and follow these common sense tips for protecting your dental work.

Brushing and flossing daily, and dental visits at least twice a year: These are the essential things you should be doing to protect your teeth and gums against dental disease. But you're also getting an automatic assist from your body through saliva, that humble fluid swishing around in your mouth, to protect your oral health.
It's more than simply “mouth water”: Without saliva and its various components, your risk for tooth decay or periodontal (gum) disease would be much higher. Here are 4 ways saliva helps you keep your teeth and gums healthy.
Cleansing. Chewing prepares your food for digestion, but in the process produces tiny particles of food debris. Settling on tooth surfaces, these bits become part of the dental plaque that forms on your teeth and develops the ideal breeding ground for disease-causing bacteria. Saliva helps rinse away much of this debris—particularly sugar, the primary food source for bacteria.
Protection. Saliva is the first line defense against disease-causing microorganisms entering the mouth. The primary source of this protection is a protein-based antibody called Immunoglobulin A (IgA), which directly fights infection-causing organisms. Another protein in saliva, lactoferrin (also found in tears), interferes with bacterial growth.
Buffering. The main enemy of tooth enamel is mouth acid, produced by oral bacteria and the foods that we eat. Saliva neutralizes acid to help the mouth maintain its normally neutral pH range. And it works fast: Saliva can buffer acid and restore balance within thirty minutes to an hour after eating.
Re-mineralization. It's normal for acid to build up after eating, and for it to quickly remove minerals from surface enamel, a process called de-mineralization that can soften and weaken the enamel. But saliva helps restore some of these lost minerals as it's neutralizing acid. This re-mineralization re-strengthens enamel against tooth decay.
Saliva is so important for maintaining a healthy mouth, it's worth your efforts to protect it. Diminished saliva production not only produces an unpleasant dry mouth, it may increase your risk for disease. If this is a constant problem, speak to your dentist about causes and remedies. You'll be doing your teeth and gums a favor.

On the way to adulthood, permanent teeth steadily erupt until, if all goes normally, you have a full set of teeth. Sometimes, though, one or more teeth may fail to form. This not only can affect your dental health, but it could also diminish your smile.
For example, if the lateral incisors on either side of the central incisors (the two teeth front and center) don't develop, it could create a smile that's “not quite right.” But we can vastly improve such a smile in one of three unique ways.
The first is to fill the resulting gap through canine substitution. This is an orthodontic method in which we use braces to move the pointed canine teeth, which normally position on the other side of the missing laterals, closer to the central incisors. This choice is determined by the size of the canine teeth. If they are slim in width, they can be re-shaped to make them appear more like a lateral incisor, and the gums possibly reshaped as well around them through cosmetic surgery.
We can also install a dental bridge, an appliance that fills the missing lateral space with prosthetic teeth. A traditional bridge requires the teeth on either side of the gap to be reduced in size, which becomes a permanent alteration to accommodate these crowns. This is a disadvantage in a young person. We can also use a “bonded bridge” which uses adhesives to attach extended pieces (or “wings”) of dental material from either side of the prosthetic tooth to one or more supporting teeth. These wings are behind the permanent teeth. Though not as durable as a traditional bridge, it does avoid altering the support teeth.
Finally, we can replace the missing teeth with dental implants. In this method, we install titanium metal posts into the jawbone at the missing tooth locations and then attach a life-like crown to each one. Implants may be more costly than other restorative methods and can take several months to complete. But they are life-like, highly durable, and don't require any alteration to other teeth. A disadvantage is that you should wait until at least 19 years of age to consider this option. What many people do is use a temporary solution until the proper age to do a dental implant.
Each of these methods have their advantages and disadvantages, which should be thoroughly reviewed in consultation with your dentist. And each may also require other dental work, such as initial orthodontics to open adequate space for a restoration. But any of these methods for correcting a missing lateral tooth can be effective and help restore both a healthier mouth and a more attractive smile.

When you floss (you do floss, right?), you probably notice a sticky, yellowish substance called plaque stuck to the thread. This thin film of tiny food particles and bacteria is the reason you floss and brush in the first place: Because it's the main trigger for tooth decay and gum disease, removing it decreases your risk for disease.
But this isn't the only form of plaque you should be concerned about. That same sticky substance can also interact with your saliva and harden into what's commonly known as tartar. Dentists, however, have a different term: They refer to these calcified deposits as calculus. And it's just as much a source of disease as its softer counterpart.
You might have noticed that this form of plaque has the same name as an advanced type of mathematics. Although dental calculus has little in common with algebra's cousin, both terms trace their origins back to the same linguistic source. The word “calculus” in Latin means “small stone;” it became associated with math because stone pebbles were once used by merchants long ago to calculate sales and trades.
The term became associated with the substance on your teeth because the hardened plaque deposits resemble tiny stones or minerals—and they can be “as hard as a rock” to remove. In fact, because they adhere so firmly it's virtually impossible to remove calculus deposits with brushing or flossing alone. To effectively eliminate calculus from tooth surfaces (including under the gum line) requires the skills and special dental tools of dentists or dental hygienists.
That's why we recommend a minimum of two dental cleanings a year to remove any calculus buildup, as well as any pre-calcified plaque you might have missed with daily hygiene. Reducing both plaque and calculus on your teeth fully minimizes your risk of dental disease. What's more, removing the yellowish substance may also brighten your smile.
That's not to say daily brushing and flossing aren't important. By removing the bulk of plaque buildup, you reduce the amount that eventually becomes calculus. In other words, it takes both a daily oral hygiene practice and regular dental visits to keep your teeth healthy and beautiful.
