Your Diet and the Health of Your Teeth

 You may not know it but your diet can affect the health of your teeth in more ways than you might think. Traditionally we think of foods with high sugar contents as being the only culprits that can affect the health of our teeth but there are others. With the advent of  "power or energy" drinks there has been a marked increase in the number of people's teeth being damaged by these types of drinks. We are seeing it primarily in children because of their frequent consumption of drinks such as Gatorade and Powerade at their sporting events. These drinks do not contain high levels of sugars but instead they are highly acidic, and it is the low pH of the drink that is doing the damage. We often see the affects of these highly acidic drinks on teeth in the form of deep pitting of the teeth and erosion of the enamel. The damage can sometimes be quite extensive. Certain foods if consumed regularly can also affect the enamel of one's teeth. In our office we have seen people's teeth completely destroyed as a result of habits such as sucking on lemons. Lemon's are highly acidic and will erode tooth structure over time if eaten in inappropriate manners. Some people enjoy eating lots of citric fruits or even sucking on them, but the results of these habits can be very devastating to the teeth. We're not recommending you avoid all foods that are acidic but moderation is the key. As for the energy drinks that are so prevalent these days these are best kept to a minimum. Below is chart showing some common foods and their accompanying acidity levels.
Experts believe that consuming as few as four acidic drinks or foods a day can increase the risk of acid erosion to your teeth.

The Link Between Oral Bacteria and Joint Failure

Joint Failures Potentially Linked to Oral Bacteria

 ScienceDaily (Apr. 18, 2012) — The culprit behind a failed hip or knee replacements might be found in the mouth. DNA testing of bacteria from the fluid that lubricates hip and knee joints had bacteria with the same DNA as the plaque from patients with gum disease and in need of a joint replacement.
This study is one of many that came from the Case Western Reserve University School of Dental Medicine that have linked oral bacteria to health problems when they escape from the mouth and enter the blood. Working with University Hospitals Case Medical Center researchers, the dental, orthopedic and arthritis researchers suggest it might be the reason why aseptic loosening or prosthetic wear of the artificial joints fail within 10 years when no infection appears to be present. The pilot study's findings were reported in the April issue of the Journal of Clinical Rheumatology.
Dr. Nabil Bissada, chair of the Department of Periodontics at the dental school, said the objective of the study, "Identification of Oral Bacterial DNA in Synovial Fluid of Patients with Arthritis with Native and Failed Prosthetic Joints," was to see if bacteria like Fusobacterium nucleatum and Serratia proteamaculans found in patients with gum disease were present in the fluid. "For a long time, we've suspected that these bacteria were causing problems in arthritis patients, but never had the scientific evidence to support it," Bissada says.

The researchers recruited and studied patients seeking care at the University Hospitals Case Medical Center for osteoarthritis (the wearing of the joints) and rheumatoid arthritis (an autoimmune disease). These study participants had both natural and artificial joints. Researcher extracted samples of their synovial fluid, which is much like oil that keeps a door from squeaking. These patients also had signs of periodontitis or gum disease and undergone exams where dental plaque was obtained for the study.

Plaque build-up from the bacteria, associated with gum disease, breaks down the walls of the pockets around the teeth. The inflammation process from the bacteria acts like a gate that gives bacteria access to the blood stream. Once in the blood, the oral bacteria can induce inflammation in remote sites. These oral bacteria have been linked to heart and kidney diseases, and premature births and fetal deaths. Because these bacteria cannot be found with routine lab tests, DNA sequencing analysis of the oral bacteria and the joint fluids are performed.
