Supermodel Christie Brinkley has a one-in-a-million smile, but she is just one of millions who have benefited from today's preferred tooth-replacement technique: the dental implant. In a wide-ranging interview, Brinkley told Dear Doctor magazine about a helicopter accident she suffered while back-country skiing.
“I fractured two molars in the back of my mouth and I had to get two dental implants,” Brinkley told the magazine. “I am grateful for the dental implant technology that feels and looks so natural.”
You might think it serves little purpose to replace a missing back tooth that was barely visible in your smile to begin with — especially if you don't spend a lot of time posing for magazine covers. But this is actually not the case. Your molars are extremely important for chewing and even for maintaining a more youthful appearance.
Dentists generally agree that losing posterior (back) teeth can have many consequences for the remaining teeth and their surrounding structures, i.e., bone and gums. If back teeth are missing, the front teeth end up bearing more stress than they were built for. And there are certain things that happen when any tooth is lost, whether front or back, that can affect function and appearance.
For one thing, when a tooth is lost the adjacent teeth tend to drift into the empty space or tip towards it. This can adversely affect your bite. Too much shifting can render a tooth basically useless and also leave it more vulnerable to gum disease.
Another complication is the loss of tooth-supporting bone that inevitably occurs when teeth are lost. When a tooth comes out, the bone under it actually begins to melt away. Since back teeth support the vertical dimension of the face, their loss can cause what's known as “bite collapse” — a reduction in facial height that becomes increasingly noticeable over time and can make you look older.
A dental implant can prevent all of these things, while providing you with a replacement that looks and feels just like the tooth you lost.

In the early 1900s, a Colorado dentist noticed many of his patients had unusual brown staining on their teeth — and little to no tooth decay. What he unknowingly observed was the power of a chemical substance in his patients' drinking water — fluoride. While commonplace today, fluoride sparked a revolution — and some controversy — in dental care during the 20th Century.
After decades of research and testing, most dentists now agree that fluoride reduces decay by interfering with the disease process. The optimum pH level for the mouth is neutral; however, this environment constantly changes as we eat, especially if we ingest foods or beverages high in acidity. A high acid level softens tooth enamel (a process called de-mineralization) and can lead to erosion if not neutralized. In addition, a thin layer of bacteria-rich plaque called biofilm that adheres to tooth surfaces is also acidic and is the cause of tooth decay, possibly more so in teeth made more susceptible from enamel erosion.
When fluoride is in “the right place” (present on the tooth surface and in our saliva, the body's natural acid neutralizer), it helps inhibit de-mineralization and aids in the re-hardening of the enamel (re-mineralization).
Although fluoride needs to come into direct contact with tooth enamel for optimum effectiveness, ingesting it can also prove beneficial. The fluoride we ingest eventually becomes deposited in bone. As bone grows and changes it releases this reserved fluoride back into the bloodstream where it eventually becomes part of saliva; the saliva brings it into contact with tooth surfaces.
The two most prominent ways we encounter fluoride are through fluoridated drinking water and in toothpaste. There continues to be concerns about what constitutes safe levels of fluoride in drinking water and over possible side effects like teeth staining and changes in bone structure. However, extensive studies have conclusively shown that even minimal levels of water fluoridation and the use of fluoride toothpaste have reduced tooth decay.
As the Colorado dentist discovered over a hundred years ago, fluoride is truly remarkable as a cavity fighter. Whether you have access to fluoridated water or not, we encourage you to use fluoride toothpaste to strengthen your teeth against decay.
