BeforeReplacingYourMissingTeethYouMayNeedOtherDentalWork

Replacing missing teeth can do wonders for a smile. And you have solid options for doing so, from a partial denture to state-of-the-art dental implants. But there might be a roadblock to your restoration plan—literally. Some of your other teeth may be in the way.

When a tooth has been missing for a while, the teeth on either side of a tooth gap will naturally begin to move or “drift” into the space. This could result in an inadequate amount of available space for a prosthetic (false) tooth.

If that happens, we'll first need to move the errant teeth back to where they belong, either with traditional braces or removable clear aligners. If we're successful, we can then proceed with the missing tooth restoration.

But before starting orthodontic treatment, there may be another problem that needs our attention first. If your missing teeth are the result of periodontal (gum) disease, your gums and supporting bone may not be as healthy as they need to be. This can interfere with orthodontics, which often depends on the gums and bone around a tooth being healthy enough to reform as the tooth moves. That may not be possible if they're still infected with gum disease or you've suffered significant bone loss.

If that's the case, it may be necessary to first treat any gum disease present and rebuild the bone. The latter can often be done by grafting bone material to the area of loss. The graft then serves as a scaffold of sorts upon which new bone can grow and accumulate. And reducing gum disease, mainly by removing bacterial plaque, allows the gums to heal and regain attachment with the teeth.

Once your gums and bone are healthy again, we can then proceed with orthodontics. After the teeth are reasonably aligned, we can then complete the restoration for replacing your missing teeth, and any other cosmetic enhancements for your remaining teeth like veneers or crowns.

The entire process may take some time and multiple treatment visits. But gaining a more attractive smile in the end is well worth it.

FortheSakeofYourTeethandGumsAvoidUsingE-Cigarettes

Over the last decade, the use of e-cigarettes—popularly known as vaping—has grown into a multi-billion dollar industry. It's the "in" thing, especially among younger adults, fueled by the widespread idea that it's a safer nicotine delivery system than traditional smoking.

But growing evidence is beginning to say otherwise—that people are simply trading one unhealthy habit for another. Besides a possible link to lung disease, vaping may also adversely impact a person's oral health.

An e-cigarette is a handheld device that heats a mixture of water, flavoring and chemicals into a vapor inhaled by the user. As with traditional cigarettes, nicotine is the active ingredient in vaping mixtures, and perhaps just as addictive. One vaping cartridge, in fact, can equal the nicotine in 20 tobacco cigarettes.

Nicotine is a good starting point for analyzing vaping's potential harm on oral health. In short, nicotine is not your mouth's friend. It constricts oral blood vessels, that in turn decreases oxygen, nutrients and infection-fighting agents delivered to the gums. Individuals who routinely ingest nicotine therefore have a much higher risk for gum disease.

And, although the various flavorings in vaping mixtures have pleasant-sounding names like "cotton candy," "mint" or "cherry crush," these additives can also cause oral problems. There's some evidence that when the flavoring chemical transforms from a liquid to a gas, it may dry out and irritate the inner membranes of the mouth. This in turn can increase the risks for bacterial infection leading to tooth decay or gum disease.

There's also evidence other substances in vaping liquids may also prove unhealthy, even carcinogenic. This raises concerns among many doctors and dentists that vaping could eventually prove to be a prime cause for increased oral cancer.

Given what we know—as well as what we don't—it's wise to avoid either smoking or vaping. We know the first habit definitely puts your oral health at risk—and the growing evidence shows the latter may be just as harmful. Avoiding both habits may be in your best interest—not only for your overall health, but for your mouth as well.

YouCanMakeCosmeticDentalChangesWhileStillKeepingYourUniqueSmile

According to Dr. Suess, "Today you are You, that is truer than true. There is no one alive who is Youer than You." Indeed, you are different from everyone else on the planet. Your fingerprints, your DNA, even the shape of your outer ear, are all unique to you. And, in a society that pressures all of us to be alike, it's good to be reminded from time to time that it's okay to be different—including how your smile looks.

In fact, the thought has such a nice ring to it that some folks designate January as "It's OK to be Different Month," a good time to celebrate all the many ways we're unique from one another—and even in ways that might be considered imperfections.

For example, in terms of smiles, some people have a slight gap between their front teeth. Technically, it's a dental defect, and we can usually correct it with veneers or orthodontics. But a lot of people, including celebrities like Michael Strahan and Madonna, want to keep their gap—they consider it part of their personality, something that makes them, them.

The same could be said for other smile "quirks" like moderate dental misalignments (crooked teeth) or color variations—even a chipped tooth. If you consider it a comfortable part of who you are, then you do you, boo.

On the other hand, if there's something about your smile that you feel detracts from your appearance, you shouldn't have to live with it. And, fortunately, you don't.

Chipped tooth? Composite bonding could make it whole again. Misaligned teeth? Braces or clear aligners can straighten your smile. Missing teeth? You have numerous tooth-replacement options, with durable and life-like dental implants far and away the reigning champ of restorations.

More importantly, we can ensure that any cosmetic improvements you undergo enhance your uniqueness rather than diminish it. For example, we can fine-tune teeth whitening of dull and dingy teeth to achieve the level of brightness with which you're most comfortable—be it subtly natural or Hollywood dazzling.

The bottom line is that you can certainly undergo a complete smile makeover that radically transforms your appearance. Or, you can simply receive a few light cosmetic touches to make the smile you already like even better.

It's your decision—and it all begins with an exam to assess your current dental situation, followed by a discussion of your options. From there, you can choose just how much you want to change about your "Youer than you" smile.

WhatChrissyTeigensInaugurationNightCapMishapCouldMeanForYou

Inauguration night is usually a lavish, Washington, D.C., affair with hundreds attending inaugural balls throughout the city. And when you're an A-List celebrity whose husband is a headliner at one of the events, it's sure to be a memorable night. As it was for super model Chrissy Teigen—but for a slightly different reason. During the festivities in January, Teigen lost a tooth.

Actually, it was a crown, but once she told a Twitter follower that she loved it “like he was a real tooth.” The incident happened while she was snacking on a Fruit Roll-Up (those sticky devils!), and for a while there, husband and performer John Legend had to yield center stage to the forlorn cap.

But here's something to consider: If not for the roll-up (and Teigen's tweets on the accident) all of us except Teigen, her dentist and her inner circle, would never have known she had a capped tooth. That's because today's porcelain crowns are altogether life-like. You don't have to sacrifice appearance to protect a tooth, especially one that's visible when you smile (in the “Smile Zone”).

It wasn't always like that. Although there have been tooth-colored materials for decades, they weren't as durable as the crown of choice for most of the 20th Century, one made of metal. But while gold or silver crowns held up well against the daily grind of biting forces, their metallic appearance was anything but tooth-like.

Later, dentists developed a hybrid of sorts—a metal crown fused within a tooth-colored porcelain shell. These PFM (porcelain-fused-to-metal) crowns offered both strength and a life-like appearance. They were so effective on both counts that PFMs were the most widely used crowns by dentists until the early 2000s.

But PFMs today make up only 40% of currently placed crowns, down from a high of 83% in 2005. What dethroned them? The all-ceramic porcelain crown—but composed of different materials from years past. Today's all-ceramic crowns are made of more durable materials like lithium disilicate or zirconium oxide (the strongest known porcelain) that make them nearly as strong as metal or PFM crowns.

What's more, coupled with advanced techniques to produce them, all-ceramic crowns are incredibly life-like. You may still need a traditional crown on a back tooth where biting forces are much higher and visibility isn't an issue. But for a tooth in the “Smile Zone”, an all-ceramic crown is more than suitable.

If you need a new crown (hopefully not by way of a sticky snack) or you want to upgrade your existing dental work, see us for a complete exam. A modern all-ceramic crown can protect your tooth and enhance your smile.

TakeStepstoStopChronicDryMouthandAvoidDentalDisease

We all experience that unpleasant "cotton-mouth" feeling now and again. But what if it happens all the time? Chronic dry mouth is more than unpleasant—it could be a medical condition that threatens your oral health.

Chronic dry mouth is a sign you don't have enough saliva present. That's a problem because we need saliva to keep our teeth and gums healthy by neutralizing the oral acid that erodes tooth enamel. Saliva also supplies antibodies to fight infection.

A saliva deficiency could be the result of lifestyle habits like drinking alcohol or smoking, metabolic diseases or treatments like chemotherapy or radiation. More commonly, though, it's a side effect from a medication you're taking.

Given the heightened risk it causes to your teeth and gums, what can you do to alleviate chronic dry mouth?

Review your medications. If you're taking prescribed medications, talk with your pharmacist or doctor about possible oral side effects associated with any of them. If so, it may be possible to switch to an alternative medication without the dry mouth side effect.

Don't use tobacco. Regardless of whether you smoke, dip or chew, tobacco use can interfere with saliva production. Kicking the habit not only improves saliva flow, it may further reduce your risk for oral diseases, especially oral cancer.

Drink more water. Saliva is mainly composed of water—so, be sure your body has plenty of it to facilitate saliva production. It's a good idea to sip extra water throughout the day, and especially before and after you take medication.

Practice oral hygiene. As a general rule, brushing and flossing every day is pivotal in preventing dental disease—but it's especially important with dry mouth. Be sure, then, to brush twice and floss once every day. You should also see your dentist at least every six months for dental cleanings and checkups.

Chronic dry mouth could be setting you up for future dental disease. But taking steps to alleviate it while practicing daily dental care could help you avoid that unhappy outcome.

If you would like more information on alleviating chronic dry mouth, please contact us or schedule an appointment for a consultation. You can also learn more about this topic by reading the Dear Doctor magazine article “10 Tips for Dealing With Dry Mouth.”
