Before she began hosting the long-running TV competition Top Chef, Padma Lakshmi was a well-known model and successful cookbook author. (Appropriately, she is said to have been “discovered” by a modeling agent while sitting in a café in Madrid.) Yet the Indian-born beauty's striking look — at once exotic and familiar — doesn't come from any cookie-cutter mold.

So when Lakshmi had cosmetic work done on her teeth, early in her career, her dentist didn't use a cookie-cutter approach either: Instead, her smile was carefully designed, using small amounts of bonding material to brighten her teeth and to bring their shape and spacing into harmony with her facial features.

Dentistry by Design
What exactly is smile design — and what could it do for you? Essentially, it's the process of evaluating your smile in concert with the appearance of your entire face, and visualizing the changes — some dramatic and some subtle — that will make it really shine. Some aspects we consider include the face's shape, the proportion or “balance” of facial features, the complexion, eye and lip color and form, and the overall dimensions of the smile.

Based on dental aesthetics and clinical experience, we will probably have a number of suggestions to make on how you can improve your smile. Your input will also be very important; while some individuals prefer perfectly even teeth and a sparkling “Hollywood white” smile, others are looking for a result that's more in keeping with a “natural” look: slight irregularities in tooth shape, spacing, and even color.

There's no right or wrong answer here: Having a “perfect” smile means what's perfect for you, so it's very important for dentists and patients to communicate openly during the smile design process. But sometimes, words alone just aren't enough to convey the subtle dimensions of beauty.

The Trial Smile
Fortunately, it's now possible to preview your “perfect” smile using a number of different techniques. Advances in computer imaging make this the first step in previewing your new smile — you can see the changes before a single tooth is touched! Still, many people find that having a more concrete picture is helpful. The next step is to make a 3-D mock-up the proposed dental work on an actual model of your mouth. That way, you can see a physical representation of the final results — and even turn it around and hold it in your hands.

There's still one more way to really experience the difference cosmetic treatments can make without committing to a permanent change: the provisional restoration. Here, tooth-colored bonding material and other techniques are used to actually create the new smile — temporarily. This gives you time to “live with it,” and see if the proposed changes work for you. If everything goes well with the provisional work, the permanent restoration is guaranteed to please.

So if you want holiday treats, get out the cookie cutter — but if you're looking for a smile that's uniquely yours, and one that enhances your own individual appearance… call our office and ask about a smile design consultation. You can learn more in the Dear Doctor magazine articles “Great Expectations — Perceptions in Smile Design” and “Beautiful Smiles by Design.”

WhatstheRightAgeforDentalImplants

Maybe you've seen some marketing material for dental implants featuring smiling, silver-haired seniors. Perhaps this made you think that implants are a tooth replacement system that's primarily intended for older adults. If so, let's change that impression right now: Dental implants are suitable for almost all adults, not just older folks!

Today's best option for tooth replacement, implants can help most people who suffer from the problem of missing or failing permanent teeth. (In children, however, where the jaw is still growing, implants aren't generally used.) Of course, it is our goal as dentists to preserve as many of the natural teeth as possible. But when that isn't possible, implants offer the best option for tooth replacement.

The Implant System
What makes the dental implant system such a great option for replacing lost teeth? Let's start with the implant itself. This small, screw-shaped device is made of titanium metal, which has a unique property: When placed in the jaw, in a minor surgical procedure, it becomes fused with the living bone tissue. This provides a solid anchor for the visible part of the replacement tooth, the crown, which is attached to the implant by a connecting piece called an abutment.

Because the implant is securely fixed in the jaw, it provides the replacement tooth with a firm foundation that won't come loose — and it doesn't depend on other teeth for support, like bridges do. It also stops the process of bone loss, which occurs in the area of the jaw where a missing tooth was formerly located. The erosion of bone, which begins as soon as a tooth is lost, can create the appearance of premature aging, and may eventually lead to further dental problems.

Why You May Need Implants
Older folks aren't the only ones who experience tooth loss; younger people suffer from this problem too. Accidents and injuries are one cause, whether they are sports-related, or result from habits like biting pencils or grinding teeth. Lifestyle may be another factor. Poor nutrition, excessive consumption of sugary substances (including certain “sports” and “energy” drinks), and the lack of proper dental hygiene and professional care can allow moderate problems to get much worse.

A major cause of tooth loss is disease, such as tooth decay or periodontal disease. These can be a problem at any age. But a few conditions may cause serious dental problems in younger people — bulimia, for example. When stomach acids enter the mouth, they can rapidly erode the tooth enamel. Gastroesophageal reflux disease (GERD) can create similar problems.

When Should You Get Implants?
Preserving your natural teeth whenever possible is a major goal of modern dentistry. But when teeth can't be saved, it's time to consider implants. While they are initially more expensive than more traditional tooth replacement methods (like bridges or removable dentures), they can last for the rest of your life with only routine care. That's something no other method can claim, and it makes them a great value, especially for younger people. Plus, they feel completely natural and look great.

So, if you're confronting the problem of tooth loss, call our office for a consultation about dental implants. You can learn more in Dear Doctor magazine's in-depth guide, “Dental Implants.”
