Dental implants have revolutionized restorative dentistry. Not only are they the top choice for individual tooth replacement, implants also improve upon traditional dental work.
Dental bridges are a case in point. A few well-placed implants can support a fixed bridge instead of natural teeth, as with a traditional bridge. Furthermore, a fixed, implant-supported bridge can replace all the teeth on a jaw.
But although convenient, we can't simply install an implant-supported bridge and forget about it. We must also protect it from what might seem at first an unlikely threat—periodontal (gum) disease.
Although the bridge materials themselves are impervious to infection, the natural tissues that underly the implants—the gums and bone—are not. An infection plaguing the gums around an implant can eventually reach the bone, weakening it to the point that it can no longer support the imbedded implants. As the implants fail, so does the bridge.
To guard against this, patients must regularly remove any buildup of plaque, a thin biofilm that feeds disease-causing bacteria, adhering to the implant surfaces in the space between the bridge and the gums. To do this, you'll need to floss—but not in the traditional way. You'll need some form of tool to accomplish the job.
One such tool is a floss threader. Similar to a large needle, the threader has an eye opening at one end through which you insert a section of floss. You then gently pass the threader between the bridge and the gums toward the tongue.
Once through, you release the floss from the threader, and holding each end, you work the floss along the implant surfaces within reach. You then repeat the threading process for other sections until you've flossed around all the implants.
You might also use a water flosser, a device that directs a spray of water between the bridge and gums. The pressure from the spray loosens and flushes away any plaque around the implants.
Whatever the method, it's important to use it every day to reduce the threat of gum disease. You should also see your dentist regularly for further cleanings and checkups. Keeping your implants clean helps ensure gum disease won't ruin your fixed bridge—or your attractive smile.

In the realm of dental restorations, not all crowns are alike. And, one type isn't necessarily superior to the others. One type of crown may work better for a particular tooth, while a different crown is better suited to another.
Therefore, knowing your options can help you make a more informed choice with your dentist regarding the best crown for your needs. Here, then, is a quick primer on the main types of dental crowns used today.
Metal crowns. Early in the last century, crowns made of gold, silver or other metals were the go-to dental restoration. Because of their strength and durability, metal crowns are still used today, mainly in back teeth that encounter heavy biting forces. Their drawback: They're decidedly not the color of natural teeth and so can stand out if they're placed in the visible "smile zone."
PFM crowns. The first crowns made with dental porcelain solved the appearance problem, but couldn't adequately handle biting forces as well as metal. Out of this came the porcelain fused to metal (PFM) crown, which contains an inner core of metal overlaid with tooth-colored porcelain. Providing both strength and life-likeness, PFM crowns were immensely popular until the mid-2000s.
All-Ceramic crowns. The development of porcelains more durable than earlier versions eventually dethroned the PFM (although the latter is still used today). Sixty percent of the crowns installed in recent years are all-ceramic, many reinforced with a strength material known as Lucite. Many all-ceramic crowns reaching the 15-year mark are still in place and functioning.
All of these crowns continue to be viable options for dental patients. The biggest factor in choosing one particular crown over another is the type of tooth involved and its location. As mentioned before, metal or PFM crowns are usually better for back teeth where durability is a higher priority than aesthetics. All-ceramics work well in high-visibility front teeth that normally encounter lighter biting forces than back teeth.
Regardless of which kind eventually caps your tooth, any of today's modern crowns will function as intended. But the best crown for you will be the one that both protects your tooth and enhances your smile.

Although we've advanced leaps and bounds over the years treating dental disease, our strategy for preventing them hasn't changed much. That's because these prevention basics are quite effective—and as the old saying goes, "If it ain't broke, don't fix it."
The core of an effective dental disease prevention strategy is mind-numbingly simple—brush and floss every day. These twin cleaning tasks remove accumulated dental plaque, a thin, bacterial film on tooth surfaces that's the primary oral disease driver.
True, there have been innovations concerning the "tools of the trade," i.e., toothbrushes, toothpastes and flossing devices. But what really makes this prevention strategy work is a consistent daily habit of oral hygiene.
In a way, simply "showing up" for daily oral hygiene goes a long way. But you can go even farther if you perform these tasks with greater proficiency—becoming a hygiene "ninja," of sorts.
Here, then, are 4 tips to improve your brushing and flossing prowess.
Be thorough when you brush. Try to cover all of your tooth surfaces when you brush, being sure to work the bristles into all the nooks and crannies and around the gum lines. A thorough brushing should take about 2 minutes.
Easy does it. Hard scrubbing may work on floors, but not your teeth—aggressive brushing can damage your enamel and gums. Brush gently and let the mild abrasives in your toothpaste do the heavy work of plaque removal.
Don't forget to floss. Although you may not like this "other hygiene task," flossing is necessary to remove plaque between teeth that your brush can't reach. Be sure, then, that you floss at least once a day.
Take the "tongue test." Wondering how well you're doing with your oral hygiene? A quick way to find out is by swiping your tongue across your teeth: If they feel gritty rather than smooth, you may have left some plaque behind.
Be sure to also ask your dentist for additional tips on better brushing and flossing. Improving your technique can help you put even more distance between you and dental disease.

Knowing what to do—and what not to do—when your child is sick can greatly affect their health and well-being. That's especially true with dental problems.
Here then are some Dos and Don'ts for 3 common problems children experience with their teeth and gums.
Teething. An infant's first teeth breaking through the gums is a normal but often unpleasant experience. Fortunately, teething episodes only last a few days. And, there's usually no need to see the dentist unless they have a fever or diarrhea while teething. In the meantime:
- Do: provide them chilled (not frozen) cloth or plastic items to bite and gnaw, and massage their gums to relieve painful pressure. You can also give them an age-appropriate dose of a mild pain reliever.
- Don't: rub any medication on their gums, which can irritate them and other soft tissues. Never use alcohol or aspirin to alleviate teething discomfort. And avoid using anything with benzocaine, a numbing agent which can be hazardous to young children.
Toothache. Whether a momentary sensitivity to hot or cold or a sharp, throbbing pain, a child's toothache often signals tooth decay, a bacterial disease which could eventually lead to tooth loss.
- Do: make a dental appointment at your child's first complaint of a toothache. Ease the pain with a warm-water rinse, a cold compress to the outside of the jaw, or a mild pain reliever.
- Don't: rub medication on the teeth or gums (for similar reasons as with teething). Don't apply ice or heat directly to the affected tooth or gums, which can burn them.
Bleeding gums. Gum bleeding from normal brushing or flossing, along with red or swollen gums, may indicate periodontal (gum) disease. Although rare in children, it can still happen—and it can put an affected tooth in danger.
- Do: see your dentist if bleeding continues for a few days. Continue to brush gently with a soft-bristled toothbrush around the gums to remove plaque, a thin-biofilm most responsible for gum infection.
- Don't: brush aggressively or more than twice a day, which could unnecessarily irritate and damage the gums. And don't stop brushing—it's important to remove plaque buildup daily to lessen the gum infection.
You’re considering dental implants and you’ve done your homework: you know they’re considered the best tooth replacements available prized for durability and life-likeness. But you do have one concern — you have a metal allergy and you’re not sure how your body will react to the implant’s titanium and other trace metals.
An allergy is the body’s defensive response against any substance (living or non-living) perceived as a threat. Allergic reactions can range from a mild rash to rare instances of death due to multiple organ system shutdowns.
A person can become allergic to anything, including metals. An estimated 17% of women and 3% of men are allergic to nickel, while 1-3% of the general population to cobalt and chromium. While most allergic reactions occur in contact with consumer products (like jewelry) or metal-based manufacturing, some occur with metal medical devices or prosthetics, including certain cardiac stents and hip or knee replacements.
There are also rare cases of swelling or rashes in reaction to metal fillings, commonly known as dental amalgam. A mix of metals — mainly mercury with traces of silver, copper and tin — dental amalgam has been used for decades with the vast majority of patients experiencing no reactions. Further, amalgam has steadily declined in use in recent years as tooth-colored composite resins have become more popular.
Which brings us to dental implants: the vast majority are made of titanium alloy. Titanium is preferred in implants not only because it’s biocompatible (it “gets along” well with the body’s immune system), but also because it’s osteophilic, having an affinity with living bone tissue that encourages bone growth around and attached to the titanium. Both of these qualities make titanium a rare trigger for allergies even for people with a known metal allergy.
Still, implant allergic reactions do occur, although in only 0.6% of all cases, or six out of a thousand patients. The best course, then, is to let us know about any metal allergies you may have (or other systemic conditions, for that matter) during our initial consultation for implants. Along with that and other information, we'll be better able to advise you on whether implants are right for you.
