Today’s crowns, the visible part of a tooth replacement system, can effectively mimic the shape and color of natural teeth. But not all crowns are equal — so it’s best to be well-informed before you undergo a restoration on your natural teeth such as a single crown or bridgework — or if you need a crown on a dental implant that replaces a missing tooth.
To give you a starting point, here are 3 things to keep in mind about crowns as you consider a dental restoration.
Material composition. Most crowns in years past were made of a precious metal, most notably gold. What it lacked in appearance, it made up for in performance and durability. In recent years, dental porcelain has become the popular choice because of its ability to mimic the appearance and translucent color of natural teeth. Today’s porcelains are much stronger and are used more frequently for back teeth than in years past. A common recommendation for back teeth is a hybrid crown using metal and porcelain. Metal is incorporated beneath the porcelain in this type of crown to create a strong foundation and is also used along biting surfaces for strength. Porcelain is used in the more visible areas for esthetics.
The dental technician’s level of artistry. Most dentists sub-contract crown fabrication to dental laboratory technicians who may have varying levels of experience and artistic ability. A highly skilled technician can produce a crown that blends seamlessly with the patient’s remaining natural teeth.
Take a “test drive” of your future smile. Although we as dentists adhere to certain aesthetic principles, beauty is ultimately subjective — “in the eye of the beholder.” The final product must meet your expectations and level of comfort. If available, then, consider wearing temporary “trial smile” crowns as a preview of your new smile while your permanent set is under construction. This allows you to “try out” your future smile ahead of time, so you can make recommendations and sign off on the final set before it’s finished.
Undertaking any dental restoration is an important life step, both for your health and appearance. Being well-informed — especially about the crowns that you and others will see — will help you make wise choices that lead to a satisfying outcome.
Recently, a number of new filling materials that mimic tooth color have come into popular use and, so far, have proven more durable than past versions. Even so, the traditional metal-based dental amalgam remains a viable choice, especially for less visible back teeth and their higher biting forces.
Used for more than a century, dental amalgam is a metal alloy composed of silver, mercury, tin and copper. The mixture is carefully proportioned so that potentially hazardous mercury is kept to a minimum and bonded with the other metals. Amalgam in its initial form is quite pliable so that it can be molded into the tooth structure under repair. Afterward it sets hard to form a durable filling that can withstand the daily force generated when we bite and chew food.
Besides durability, dental amalgam rarely causes an allergic reaction in a patient, and it’s easy for trained dentists to apply. On the downside, however, it can cause temporary temperature sensitivity in the tooth just after filling, and the tooth itself may require some removal of healthy structure to help keep the filling in place. And from an aesthetic point of view, its metallic appearance is considered unattractive especially for front teeth.
The presence of mercury in amalgam has also raised concerns over the years. “Free” mercury — atoms that escape through vapor emitted by the metal — can enter the bloodstream and potentially harm the nervous system. But after extensive study and research, U.S. and international health bodies including the American Dental Association have concluded any free mercury released during chewing is extremely low and well below any harmful levels. These studies have also found no ill effects in either children or adults with dental amalgam fillings.
Deciding on the type of filling material to use — dental amalgam or a newer composite resin, resin ionomer or glass ionomer — depends on a number of factors including the location of the teeth to be filled, the extent of decay and your personal preferences. Taking these into account, we’ll be happy to discuss which type of filling will suit you best for repairing decayed teeth.

People improve their smiles for a lot of reasons: to better their career prospects, to put some juice in their social lives or just to do something special for themselves. But you may have an even stronger reason: a once-in-a-lifetime event—maybe your wedding day—is coming up soon.
You have several options for transforming your smile for the big day—and some are even quite economical. Here are 4 affordable ways to make your smile beautiful for that forever moment.
Cleanings. While dental cleanings should already be part of your regular dental care, scheduling one right before a big event can do wonders for your smile. Not only can your hygienist remove any lingering dull and dingy plaque and tartar, but they can polish your teeth for a brighter shine. Remember, though: dental cleanings support your own hygiene efforts, they don't replace them. Your own daily practice of brushing and flossing will also help you maintain a beautiful smile.
Teeth Whitening. You can also get an extra boost of brightness with a tooth whitening procedure. Using a professional bleaching solution and other techniques, your dentist can lighten your smile to your tastes, from a more natural hue to dazzling white. The whitening effect, though, is temporary, so plan to see your dentist no more than a few weeks before your big day.
Bonding. Perhaps a tiny chip is all that stands between you and a knockout smile. Your dentist may be able to repair that and other minor defects by bonding tooth-colored materials to the chip site. These composite resin materials have the shine of enamel and can be color-blended to match your tooth's natural shade. Composite resins are also fairly rugged, although you should avoid biting down on hard foods or objects.
Veneers. Although more expensive than the previous options mentioned, veneers are still affordable compared to crowns or bridgework. Usually made of thin layers of dental porcelain, dentists bond veneers to the front of teeth to mask mild to moderate problems like heavy staining, disfiguration and minor gaps. But because veneers are custom-fabricated by a dental lab, you'll need to plan them with your dentist at least six months before your event. The resulting change to your smile, though, may well be worth the wait.

For decades, traditional braces were the only orthodontic choice for moving misaligned teeth. Although they’re quite effective, they can cause discomfort and, for teens especially, embarrassment due to their noticeable metallic appearance.
In recent years, though, technology has produced an alternative to braces that’s proven effective for many types of patients. Besides being less cumbersome and disruptive to everyday life than braces, clear aligners have another advantage that appeals to teens — they’re much less visible.
Introduced in the late 1990s, clear aligners are a system of individual trays made of nearly invisible polyurethane plastic worn over the upper teeth. The trays are computer-generated based on the patient’s individual mouth structure captured in photographs and x-rays. Each tray in the sequence is incrementally smaller in size; the patient begins wearing the first aligner in the series for about two weeks, 20 to 22 hours a day. They then switch to the next tray in the series for about the same amount of time, and continue in this fashion until they’ve worn each aligner in the series.
Besides their improvement in appearance, aligners also have another advantage: unlike traditional braces, aligners can be removed from the mouth for eating or on a limited basis for rare important social occasions. Brushing and flossing are also much easier with aligners, which don’t pose the same access problems as traditional braces.
Clear aligners were once only effective with select types of orthodontic patients, which didn’t always include teens. Over the last decade, however, significant changes to design and additional implements have widened their application to more patients, especially teens. For example, we can now add tiny “power ridges” to the aligner design that give greater precision over desired tooth movement to create a more controlled and efficient force on the teeth. More recent aligners are also being produced with a thinner, more comfortable material.
A thorough orthodontic exam will tell whether your teen is a good candidate for clear aligners. If so, they’ll benefit from a more comfortable and less embarrassing experience while gaining a new smile for life.

Sometimes it seems that appearances count for everything—especially in Hollywood. But just recently, Lonnie Chaviz, the 10-year-old actor who plays young Randall on the hit TV show This Is Us, delivered a powerful message about accepting differences in body image. And the whole issue was triggered by negative social media comments about his smile.
Lonnie has a noticeable diastema—that is, a gap between his two front teeth; this condition is commonly seen in children, but is less common in adults. There are plenty of celebrities who aren’t bothered by the excess space between their front teeth, such as Michael Strahan, Lauren Hutton and Vanessa Paradis. However, there are also many people who choose to close the gap for cosmetic or functional reasons.
Unfortunately, Lonnie had been on the receiving end of unkind comments about the appearance of his smile. But instead of getting angry, the young actor posted a thoughtful reply via Instagram video, in which he said: “I could get my gap fixed. Braces can fix this, but like, can you fix your heart, though?”
Lonnie is raising an important point: Making fun of how someone looks shows a terrible lack of compassion. Besides, each person’s smile is uniquely their own, and getting it “fixed” is a matter of personal choice. It’s true that in most circumstances, if the gap between the front teeth doesn’t shrink as you age and you decide you want to close it, orthodontic appliances like braces can do the job. Sometimes, a too-big gap can make it more difficult to eat and to pronounce some words. In other situations, it’s simply a question of aesthetics—some like it; others would prefer to live without it.
There’s a flip side to this issue as well. When teeth need to be replaced, many people opt to have their smile restored just the way it was, rather than in some “ideal” manner. That could mean that their dentures are specially fabricated with a space between the front teeth, or the crowns of their dental implants are spaced farther apart than they normally would be. For these folks, the “imperfection” is so much a part of their unique identity that changing it just seems wrong.
So if you’re satisfied with the way your smile looks, all you need to do is keep up with daily brushing and flossing, and come in for regular checkups and cleanings to keep it healthy and bright. If you’re unsatisfied, ask us how we could help make it better. And if you need tooth replacement, be sure to talk to us about all of your options—teeth that are regular and “Hollywood white;” teeth that are natural-looking, with minor variations in color and spacing; and teeth that look just like the smile you’ve always had.
Because when it comes to your smile, we couldn’t agree more with what Lonnie Chaviz said at the end of his video: “Be who you want to be. Do what you want to do. Do you. Be you. Believe in yourself.”
