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 humble squirrel—darlings to some, bird feeder-robbing nuisances to others—has its own month. Since 1995, the Squirrel Lovers Club of Chicago has celebrated October as Squirrel Awareness Month to pay tribute to this diverse family of rodents with over 270 species. It's also an opportunity to indulge in our favorite “squirrelly” fact: Squirrels' teeth don't stop growing.
And we do mean grow. A squirrel's four front incisors increase about 6 inches a year—a good thing since squirrels put those teeth through their paces gnawing through hard-shelled nuts and seeds. If they didn't keep growing, you'd see plenty of squirrels with worn-to-nothing front teeth.
We humans have some cause to be envious because, unlike squirrels, our permanent teeth stop growing by the time we reach adulthood. That could be a problem since nearly all of us encounter tooth wear as we age.
And it could be even worse. Bad habits like crunching ice, biting into hard foods or using our teeth as tools can contribute to accelerated wear. Some people also involuntarily clench or grind their teeth, creating higher than normal pressure that can wear down teeth.
Suffice it to say, it's worth the effort to quit conscious bad dental practices to prevent your teeth from wearing faster than normal. A teeth-grinding habit, though, may require more than willpower: We'll need to look at other ways to reduce its effect on your teeth.
First, you may want to try to reduce chronic stress, the top contributor to adult teeth grinding. Better stress management with the help of counseling, relaxation techniques, biofeedback or group therapy can all help reduce the occurrence of this destructive habit.
Such efforts, though, can take time. In the meantime, we may be able to help you reduce the effect of a grinding habit with a custom-made mouth guard. This plastic guard worn in the mouth prevents teeth from making hard contact with each other during grinding, and so it reduces the damaging forces that can wear down teeth.
By the way, if you've already experienced excessive tooth wear, not all hope is lost. We may be able to restore your teeth to normal length with the help of bonded porcelain veneers or crowns. After a thorough evaluation, we can give you options for turning back the “age clock” on your smile.
Our teeth may not continuously grow like squirrels', but we can still protect them from the effects of excessive wear. Good dental practices and habits—and restorative measures when necessary—can keep your smile looking as young as ever.
Celebrities’ controversial actions and opinions frequently spark fiery debates on social media. But actress Dakota Johnson lit a match to online platforms in a seemingly innocent way—through orthodontics.
This summer she appeared at the premier of her film The Peanut Butter Falcon missing the trademark gap between her front teeth. Interestingly, it happened a little differently than you might think: Her orthodontist removed a permanent retainer attached to the back of her teeth, and the gap closed on its own.
Tooth gaps are otherwise routinely closed with braces or other forms of orthodontics. But, as the back and forth that ensued over Johnson’s new look shows, a number of people don’t think that’s a good idea: It’s not just a gap—it’s your gap, a part of your own uniqueness.
Someone who might be sympathetic to that viewpoint is Michael Strahan, a host on Good Morning America. Right after the former football star began his NFL career, he strongly considered closing the noticeable gap between his two front teeth. In the end, though, he opted to keep it, deciding it was a defining part of his appearance.
But consider another point of view: If it truly is your gap (or whatever other quirky smile “defect” you may have), you can do whatever you want with it—it really is your choice. And, on that score, you have options.
You can have a significant gap closed with orthodontics or, if it’s only a slight gap or other defect, you can improve your appearance with the help of porcelain veneers or crowns. You can also preserve a perceived flaw even while undergoing cosmetic enhancements or restorations. Implant-supported replacement teeth, for example, can be fashioned to retain unique features of your former smile like a tooth gap.
If you’re considering a “smile makeover,” we’ll blend your expectations and desires into the design plans for your future smile. In the case of something unique like a tooth gap, we’ll work closely with dental technicians to create restorations that either include or exclude the gap or other characteristics as you wish.
Regardless of the debate raging on social media, the final arbiter of what a smile should look like is the person wearing it. Our goal is to make sure your new smile reflects the real you.

Parents have been dealing with their children's teething pain for as long as parents and children have been around. Along the way, the human race has developed different ways to ease the discomfort of this natural process of dental development. While most are good, common-sense measures, one in particular needs to be avoided at all costs—applying topical oral products to the gums containing Benzocaine.
Benzocaine is a topical anesthetic often found in oral products like Anbesol, Orajel or Topex to help ease tooth pain or sensitivity. The agent can be found in gel, spray, ointment or lozenge products sold over-the-counter. As an analgesic, it's considered relatively safe for adults to use.
But that's not the case with infants or younger children. Researchers have found a link between Benzocaine and methemoglobinemia, a potentially fatal blood condition. Methemoglobinemia elevates the amount of a hemoglobin-like protein called methemoglobin, which in high concentrations can lower oxygen levels being transported to the body's cells through the bloodstream.
Because of their smaller anatomy and organ systems, younger children can have severe reactions to increases in methemoglobin, which can range from shortness of breath or fatigue to seizures, coma or even death. That's why you should never use products with Benzocaine or similar numbing agents to ease teething pain. Instead, follow these common sense practices:
- Give your child chilled rubber teething rings, wet washcloths or pacifiers to chew or gnaw on. The combination of cold temperatures and pressure from biting on them will help ease the pain. Just be sure the item isn't frozen, which could cause frost burns to soft tissues.
- For temporary relief from soreness, gently massage your baby's gums with a clean, bare finger or with it wrapped in a clean, wet cloth. The massaging action helps counteract the pressure of the incoming tooth.
- For intense episodes of teething discomfort, ask your healthcare provider about using an over-the-counter pain reliever like acetaminophen or ibuprofen. Be sure you use only the recommended dose size for your child's age.
Teething is in many ways like a storm—it too shall pass. Be sure you're helping your baby weather it safely.
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.
