DeterminingtheRightWhiteningApproachisKeytoBrighteningaDullSmile

Bright, naturally white teeth are a key component in a beautiful smile. But the opposite is also true: nothing diminishes an otherwise attractive smile more than stained or discolored teeth.

There is good news, however, about tooth staining: it can be greatly reduced with the right whitening technique. But before taking action we need to first uncover the cause for the staining — whether from the outside or inside of the tooth, or a combination of both.

If it’s an external cause — known as extrinsic staining — our diet is usually the source. Foods and beverages that contain tannins, like red wine, coffee or tea fall in this category, as do foods with pigments called carotenes as found in carrots and oranges. Besides limiting consumption of stain-causing foods and maintaining daily oral hygiene, you can also diminish extrinsic staining with a bleaching application.

There are two basic ways to approach this: with either a professional application at our office or with a home kit purchased at a pharmacy or retail store. Although both types use similar chemicals, the professional application is usually stronger and the whitening effect is obtained quicker and may last longer.

Discoloration can also occur within a tooth, known as intrinsic staining, and for various reasons. It can occur during tooth development, as with childhood overexposure to fluoride or from the antibiotic tetracycline. Poor development of enamel or dentin (the main sources of natural tooth color), tooth decay, root canal treatments or trauma are also common causes of intrinsic discoloration.

There are techniques to reduce the effects of intrinsic staining, such as placing a bleaching agent inside the tooth following a root canal treatment. In some cases, the best approach may be to restore the tooth with a crown or porcelain veneer. The latter choice is a thin layer of dental material that is permanently bonded to the outer, visible portion of the tooth: it’s life-like color and appearance covers the discoloration, effectively renewing the person’s smile.

If you’ve been embarrassed by stained teeth, visit us for a complete examination. We’ll recommend the right course of action to turn your dull smile into a bright, attractive one.

AlthoughChallengingSmileZoneImplantscanAppearBeautifullyLife-Like

Dental implants have quickly become the restoration of choice for two basic reasons: they effectively restore the lost function of missing teeth and simultaneously rejuvenate the smile with their life-like appearance.

Achieving a life-like appearance, however, isn’t always a simple matter. A restoration in what we dentists call the “Smile Zone” (the upper front area that displays both teeth and the gum line when you smile) requires careful planning and technique to ensure they appear as life-like as possible.

Our first concern is whether there’s enough bone to fully anchor an implant. Bone is a living, dynamic tissue that goes through cycles of dissolving (resorption) and growth. The normal forces of biting and chewing transmit through healthy teeth and stimulate growth in the bone. When the teeth are missing and no longer transmit this pressure, the bone will eventually resorb only and not grow.

Adjacent teeth could also be affected with bone loss if the extraction was difficult and a bone graft was not placed into the extraction socket to preserve bone. This not only puts adjacent teeth at risk of gum and bone loss but can also have implications for the final smile appearance. This bone also supports the triangular tissue between teeth known as papillae which give teeth their arched appearance. If the bone isn’t adequate, there’s less hope that the papillae will regenerate.

With these concerns it’s very important to consider how the implant and crown emerges from the gums in the Smile Zone. Recent developments in implant design are helping in this regard. The design change of the top of the implant re-orients the gum tissues in relation to the implant from vertical to horizontal, which dentists call “platform switching.” This provides greater stabilization where bone mass is limited, and helps create a more aesthetically pleasing result. There are also other techniques, such as surgical tissue grafting of the papillae that can further enhance the final appearance.

Although creating a natural, life-like appearance in the Smile Zone is difficult, it’s not impossible. It’s important first to undergo a complete dental examination and profile, where we can advise you on your best options to achieve a beautiful smile.
