Since their introduction over three decades ago, dental implants have evolved into dentistry’s premier tooth replacement choice. While their primary purpose is to replace missing teeth and rejuvenate a patient’s smile, they’re also regarded for another important benefit: they can slow or stop bone loss accelerated by the loss of teeth.
Like all living tissue, bone has a life cycle. Older bone dissolves and is absorbed by the body, a process called resorption. New bone forms and grows to replace the resorbed bone in response to stimuli occurring within the body. In the jaw, this stimulation comes from the forces the teeth receive when we bite or chew.
When a tooth is lost, however, it no longer transmits these force stimuli to the adjacent bone. This results over time in less new growth to replace resorbed bone, and the overall bone mass shrinks. In fact, about a quarter of the normal bone width will diminish in the first year alone after tooth loss. Other serious problems follow, like gum recession or chewing and speaking difficulties. A person’s appearance may also suffer, because as resorption continues unchecked, the underlying foundational bone will continue to shrink. As more teeth are lost, a decrease in the distance between the nose and chin may result causing the lower third of the face to become smaller in size.
Dental implants can interrupt this process by encouraging bone growth around the implant. Implants are made of “osseophilic” titanium, meaning the metal has a natural affinity with bone. After implantation, bone cells will begin to grow and attach to the titanium post. The enhanced growth stabilizes bone loss by providing stimulation to the bone as teeth once did, thereby maintaining bone levels and minimizing potential effects on the patient’s appearance.
Ironically, too much bone loss could make the installation of implants more difficult, since they require a minimum level of bone mass for anchorage. Receiving an implant as soon as is practical once a tooth is lost will minimize the chances of that occurring — and a better chance of improving bone health overall.

Restoring missing or unattractive teeth can often be a lengthy process. Months may elapse between initial teeth preparation and final placement to allow time for tissue healing and permanent crown manufacturing. During that period you will likely wear temporary (provisional) crowns to protect the teeth while improving function and appearance.
In the past, provisional crowns were fairly uniform. Today, though, there are provisional crowns available that conform exactly to a patient’s individual mouth. These crowns not only enhance function and appearance, they’re an excellent way to “try out” your new smile before the permanent restoration.
Customized provisional crowns are part of a concept known as “smile analysis.” A new smile involves more than restoring affected teeth: we also consider the overall health of your mouth, the shape of your face, and your own desires and expectations. Your final smile design is a joint collaboration between you, our office and the dental laboratory that will fashion the final restoration.
There are a number of techniques for creating customized provisional crowns. Some techniques involve bonding tooth-colored materials like composite resin directly to the teeth. Others use impression models of your teeth to create an outline or shell that’s filled with an acrylic material and then affixed to your teeth. The aim with any of these techniques is to produce a provisional crown that accurately reflects the final crown’s appearance.
With these types of provisional crowns, we can see how the new teeth will look (their color, shading, shapes and proportions) against the gums, and if they appear to be in balance and harmony with the entire face, including your lips, jaws and facial contour. We can also evaluate how well the new teeth function as you chew, speak or smile.
It takes some extra effort to prepare customized provisional crowns rather than the more uniform version. But this effort is well worth it: by helping us anticipate more accurately how your new restorations will appear and function, customized crowns help ensure your new smile is an attractive and satisfying one.

From the time they're born, you do everything you can to help your children develop a healthy body. That should include their teeth and gums. It's not over-dramatizing to say that what you do now may set the pattern for a healthy mouth for the rest of their life.
Here, then, are 4 things you should be doing for your children's oral health before they begin school.
Train them to brush and floss. Good hygiene habits have one primary purpose — remove dental plaque, a thin film of bacteria and food particles that builds up on tooth surfaces. Plaque is the number one cause of tooth decay and periodontal (gum) disease, so focus on brushing and later flossing as soon as their first teeth appear in the mouth, gradually training them to perform the tasks themselves. You can also teach them to test their efforts with a rub of the tongue — if it feels smooth and “squeaky,” their teeth are clean!
Keep your own oral bacteria to yourself. Children aren't born with decay-producing bacteria — it's passed on to them through physical contact from parents and caregivers. To limit their exposure to these “bad” bacteria, avoid kissing infants on the lips, don't share eating utensils and don't lick a pacifier to clean it off.
Eat healthy — and watch those sweets. Building up healthy teeth with strong enamel is as important to decay prevention as daily hygiene. Be sure they're getting the nutrients they need through a healthy diet of fresh fruits and vegetables, protein and dairy (and set a good example by eating nutritiously too). Sugar is a prime food source for bacteria that cause tooth decay, so avoid sugary snacks if possible and limit consumption to mealtimes.
Wean them off pacifiers and thumb sucking. It's quite normal for children to suck pacifiers and their thumbs as infants and young toddlers. It becomes a problem for bite development, though, if these habits continue into later childhood. As a rule of thumb, begin encouraging your children to stop sucking pacifiers or their thumbs by age 3.
