SeeYourDentistFirstBeforeUsingaHomeTeethWhiteningKit

Are your stained teeth bumming you out? There's good news—you can transform that dull and dingy smile yourself with a tooth whitening product.

There are dozens of over-the-counter whitening kits that allow you to brighten your own smile. Although not as controlled and long-lasting as a dentist's professional whitening, these DIY kits can still give you effective results.

But since these products involve chemical solutions that bleach tooth enamel, there's a common concern about their safety. Could you be harming your teeth by using a home whitening kit?

The answer is no—as long as you follow the manufacturer's directions for using the product. These kits have been formulated with a lower percentage of bleaching agent (usually 10% carbamide peroxide) than whitening solutions used by dentists. They've also been subjected to several clinical studies gauging both their effectiveness and safety.

That said, though, exceeding a product's recommended directions and frequency of use could cause you problems. If not used properly, a bleaching solution can erode tooth enamel—and this protective tooth layer doesn't grow back! As long as you whiten "within the lines," so to speak, you shouldn't encounter this kind of situation.

With that said, though, there are good reasons to consult your dentist before using a whitening product, or have them perform the whitening for you.

For one thing, an over-the-counter whitening product won't work if the staining originates from inside a tooth. It's wise, then, to have a dental examination first before using a whitening product to uncover this or any other underlying dental problems that should be addressed first.

You may also find a professional whitening will give you a more desirable result. A stronger professional bleaching solution under a dentist's expert control can produce a brighter, longer lasting smile than a home use product. A dentist may also be able to control the level of brightness better to help you achieve the smile effect you desire, from subtle white to ultra-bright.

Whichever way you go, your dentist can advise you on your options and make sure your teeth are in good shape for whitening. The end result can be a brighter smile—and a brighter mood.

WhichImplantCrownAttachmentMethodisBestforYou

If you've decided on a dental implant to replace a missing tooth, you've made a great choice. Implants are a big favorite of both dentists and patients, not only for their life-likeness, but also their durability. Studies show that more than 95% of implants survive after ten years.

As you may know, single tooth implants are composed of two main parts: a metal post (usually titanium) imbedded in the jawbone; and a life-like crown affixed to the end of the post. But what you may not know is that there are two ways to attach the crown—either with screws or with dental cement.

Neither way is superior to the other—both have their own set of advantages and disadvantages. A cemented crown, for instance, usually looks more like a natural tooth than a screw-retained crown (more about that later) and dentists have more flexibility in making them look natural.

But cemented crowns require an additional piece of hardware called an abutment to better match it with the implant, something unnecessary with a screw-retained crown. Some people can also experience a reaction to the cement resulting in inflammation or even bone loss. And once installed, removing the crown later for repair or replacement is much more difficult than with a screw-retained crown.

Besides attaching directly to the implant, screw-retained crowns don't require cement and are more easily attached and removed. But the screw-hole can pose some aesthetic problems: Although it can be filled with a tooth-colored filling, the tooth's appearance isn't as ideal as a cemented crown.

So, which one is best for you? That will depend on the type and location of teeth being replaced, as well as your dentist's preferences. For instance, a more attractive cemented crown may be better for a visible front tooth, while a screw-retained crown might be a good choice for a back premolar or molar where appearance isn't as big a factor.

In the end, it's likely your dentist will discuss the pros and cons for each method as it pertains to your individual case. Whichever way your crown attaches, the end result will still be a life-like tooth that could last you for years to come.

YourNewPorcelainVeneersCanLastandLookGreataLongTime

Dental veneers are a popular way to improve teeth with chips, stains, gaps or other defects. They're typically made of dental porcelain, ceramic-like materials prized for their ability to mimic the texture, color and translucency of natural teeth.

But dental porcelain doesn't come in one form—a dentist can utilize variations of it to better match a patient's need. For example, one patient may need a porcelain with added strength, while another may need one that provides better coverage of underlying discoloration.

The foundational materials for veneer porcelain are glass ceramics. Also used for crowns, glass ceramics have been the preferred choice of dentists for some time to achieve life-like results. In terms of veneers, dental technicians first mix the powdered form of the porcelain with water to create a paste. They then use the paste to build up the body of a veneer layer by layer.

But while the high degree of silica (glass) in this type of porcelain best resembles the translucence of natural teeth, early forms of it lacked strength. This changed in the 1990s when technicians began adding a material called leucite to the ceramic mixture that enhanced its strength and durability.

Today, you'll also find lithium disilicate used, which is twice as strong as leucite and is quite useful when creating thinner veneers. Both of these strength materials can be pressed and milled into shape, which helps achieve a more accurate fit. Along with the underlying glass ceramic, the result is a veneer that's both durable and incredibly life-like.

Although today's porcelain veneers are far superior in durability than earlier forms, they can be damaged when biting down on hard objects. To make sure your veneers last as long as possible, you should avoid biting down directly on hard-skinned fruit, or using your veneered teeth to crack nuts or crunch ice (or any other teeth, for that matter).

But with proper care, today's veneers have exceptional longevity. And, thanks to the superior dental materials that compose them, they'll look great for years.

HowGeorgeClooneyMadeOverHisSmileandHowYouCanToo

Since his breakout role as Dr. Doug Ross in the 90's TV drama ER, George Clooney has enjoyed a blockbuster career as an award-winning actor, director and producer. He's still going strong, as seen in the recent film The Midnight Sky, which Clooney directed and starred in. This sci-fi drama set a record as the most-watched movie on Netflix for the first five days after its late December release. And although now well into middle age, Clooney still possesses a winsome charm epitomized by his devil-may-care smile.

But he didn't always have his enigmatic grin. Early on, his struggles pursuing his burgeoning acting career triggered a stressful habit of grinding his teeth. This took a toll, as his teeth began to look worn and yellowed, giving his smile—and him—a prematurely aged appearance.

Clooney's not alone. For many of us, our fast-paced lives have created undue stress that we struggle to manage. This pent-up stress has to go somewhere, and for a number of individuals it's expressed through involuntary grinding or gritting of the teeth. This may not only lead to serious dental problems, but it can also diminish an otherwise attractive smile.

There are ways to minimize teeth grinding, the most important of which is to address the underlying stress fueling the habit. It's possible to get a handle on stress through professional counseling, biofeedback therapy, meditation or other relaxation techniques. You can also reduce the habit's effects with a custom-made oral device that prevents the teeth from making solid contact during a grinding episode.

But what if teeth grinding has already taken a toll on your teeth making them look worn down? Do what Clooney did—put a new “face” on your teeth with dental veneers. These thin layers of porcelain are bonded to teeth to mask all sorts of blemishes, including chips, heavy staining and, yes, teeth that appear shortened due to accelerated wearing. And they're custom-designed and fashioned to blend seamlessly with other teeth to transform your smile. Although they're not indestructible, they're quite durable and can last for years.

Veneers can correct many mild to moderate dental defects, but if your teeth are in worse shape, porcelain crowns may be the answer. A crown, which bonds to a prepared tooth to completely cover it, allows you the advantage of keeping your natural tooth while still enhancing its appearance.

Although different in degree, both veneers and crowns require permanently altering the teeth, such that they will require a dental restoration from then on. But if you're looking for an effective way to transform your worn or otherwise distressed teeth into a beautiful smile, it's a sound investment.

Just like George Clooney, your smile is an important part of who you are. We can help you make it as appealing as possible with veneers or other dental enhancements. Call us today to get started on the path to a more attractive smile.

If you would like more information about dental veneers and other smile enhancements, please contact us or schedule a consultation. To learn more, read the Dear Doctor magazine article “Porcelain Veneers.”

ABondedRetainer-AnotherOptionforKeepingYourNewStraightSmile

For some, the excitement over their braces coming off gets dampened a bit with the prospect of now having to wear a retainer. But it has to be—newly realigned teeth have a tendency to revert to their previous positions out of a kind of “muscle memory.” A retainer prevents that from happening.

But as essential as it is, the standard retainer is almost as noticeable as braces, a major reason why many patients are less than enthusiastic about wearing them. And, because it's common for them to become lost when out of the mouth, replacing one becomes an added expense.

But there's another option—the bonded retainer. This retainer consists of a metal wire bonded to the back of the teeth to prevent them from moving. Because it's fixed in place, only a dentist can remove it.

The bonded retainer addresses the previous two issues associated with a removable retainer. Because it's behind the teeth rather than in front, it's out of sight to others. And, because it's fixed in place, there's no danger of losing it.

But unlike its removable cousin, which can be taken out for oral hygiene, the bonded retainer can make flossing more difficult. And, by nature, a bonded retainer must be worn all the time; a removable retainer allows for a more flexible schedule later in the treatment of a few hours a day.

So, which retainer option is best for you or another family member? A bonded retainer may be more attractive for appearance's sake, if it must be worn indefinitely, or if there's a high probability of the teeth moving out of alignment. And, it might be the right choice where there's a concern about a patient's ability to keep up with a removable retainer.

If you do decide to go with a bonded retainer, ask your dental hygienist for training on using floss with the fixed appliance—this can help improve oral hygiene. Whatever you choose, bonded or removable, your retainer will help you keep that new, beautiful, straightened smile.
