ItCouldbeMoreThanaToothYoureLosing

There’s more to tooth loss than you might think. Because teeth are part of a larger system that facilitates speaking, eating and digestion, a lost tooth could eventually affect your overall health.

Tooth loss is actually about bone loss. As living tissue, bone continually reforms in response to stimuli it receives from the body. The alveolar bone (which surrounds and supports the teeth) receives such stimuli as the teeth chew and bite, as well as when they contact each other. All these stresses — hundreds a day — transmit through the periodontal ligament to the bone, stimulating it to grow and remodel.

A lost tooth reduces this stimulation and causes the alveolar bone to resorb (dissolve) — as much as 25% of its width the first year alone. Unless the process is stopped, the underlying basal bone and the periodontal (gum) tissue will begin to resorb too. Without this structural support the facial height shrinks and the front teeth begin to push forward, making chewing and speaking more difficult. These teeth begin performing functions outside their normal range, leading to damage and possible loss.

The primary goal of oral hygiene and dental care is to prevent tooth loss. When tooth loss does occur, however, it’s then important to restore the lost tooth with an artificial replacement if at all possible — not only to regain form and function, but to also stop further bone loss.

While the fixed partial denture (FPD), also known as a fixed bridge, has been the restoration of choice for many decades, dental implants may be the better long-term option. Although more expensive initially, implants can achieve a life-like restoration without involving or altering adjacent teeth as with FPDs. Plaque retention and tartar accumulations are much less likely with an implant, and the bone-loving quality of titanium, the metal used for implants, actually encourages bone growth. As a result, implants have a much higher longevity rate than FPDs.

Taking care of your teeth through effective hygiene practices and regular checkups may help you avoid tooth loss altogether. But if it can’t be avoided, restoring lost teeth is the single most important thing you can do to prevent even greater problems down the road.

NotJustFillingintheGapsLostTeethHaveUnexpectedConsequences

Why is it important to replace missing teeth with restorations such as dental implants? You might be surprised to find that the damage caused by missing teeth is much greater than the simple gaps left in your smile.

As the years go by, teeth lost early in adulthood cause structural changes in a person's face. By age 45 changes in facial structure are already visible in the form of sunken cheeks. By 60, cheeks and lips lose their support, resulting in an aging look. This process continues and if the teeth are not replaced, much of the structural support of the person's face is lost.

These changes are caused by loss of bone. Although it may seem static, bone is actually living tissue that needs constant stimulation to maintain its form and density. With normal stimulation it is in a constant state of resorption (breaking down) and deposition (building up). Teeth provide the needed stimulation for the bone that surrounds them (called alveolar bone) as they meet each other during biting, chewing, and speech. When the stimulation continues, the bone continues to rebuild itself. Without this stimulation, the bone resorbs, does not build up again, and loses substance.

Without stimulation, alveolar bone loses width, height, and volume. Since your teeth and their surrounding bone support your chin, cheeks, and lips, this has a powerful effect on your appearance. It may also affect your ability to chew and to speak.

As alveolar bone diminishes, the next layer of bone also begins to resorb. This is the bone of the jaw itself. The lower part of the face begins to collapse, and the cheeks become hollow. This effect is especially noticeable for people with no teeth (edentulous).

Usually the first tooth to be lost, due to infection and decay, is a molar (back tooth). In the past, a missing single back tooth was frequently replaced by a fixed partial denture (FPD). A crown is provided for each of the two teeth on the sides of the gap, called abutment teeth, to support a false tooth in the middle. However, if they are not well cared for, the abutment teeth may be the next to succumb to decay.

Today the treatment of choice is an implant. A dental implant is a tooth-root replacement made of titanium, which fuses with the bone — making it very stable. Above the gums it is covered by a crown that looks like a natural tooth. The benefit of the implant is that it continues to provide stimulation to the alveolar bone, preventing bone loss.

Implants are also a good choice in the case of multiple missing teeth. They can be used to support bridges or false teeth (dentures). The results are an improved, younger appearance and better functionality.
