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.

When her daughter Ashby was born in 2007, Nancy O'Dell was overjoyed; but she found the experience of pregnancy to be anxiety-provoking. O'Dell is host of the popular entertainment news show Entertainment Tonight.
After her baby was born she compiled her memories and thoughts into a book for first-time pregnant mothers. The book, “Full of Life: Mom to Mom Tips I Wish Someone Had Told Me When I Was Pregnant,” covers a wide range of topics — including oral health during pregnancy.
“While my dental health has always been relatively normal, pregnancy did cause me some concern about my teeth and gums. With my dentist's advice and treatment, the few problems I had were minimized,” O'Dell told Dear Doctor magazine. An example of her experience is a craving for milk that started at about the time the baby's teeth began to form. She felt that her body was telling her to consume more calcium.
As often happens with pregnant mothers, she developed sensitive gums and was diagnosed with “pregnancy gingivitis,” the result of hormonal changes that increase blood flow to the gums.
“I love to smile,” said O'Dell, “and smiles are so important to set people at ease, like when you walk into a room of people you don't know. When you genuinely smile you're able to dissolve that natural wall that exists between strangers.”
