Fluoride Treatment for Adults? – Newton, Wellesley, MA

If the high-pitched whir of a dentist's drill as it bores into your molar terrifies you, good news! There could be fewer fillings in your future. According to Dr. Ryne Johnson, prosthodontist and managing partner at Newton Wellesley Dental Partners, “A painless way to prevent cavities in adults is gaining traction”. Project1 Fluoride varnish is standard practice for children's teeth, and is generally done yearly.  According to Dr. Johnson, “many of my older patients are on medications that cause dry mouth, which puts them at high risk for cavities. So for these patients, we use a skinny brush and a little pot of yellowish liquid and paints the varnish on the teeth. We know that saliva helps us wash away bacteria and food in the mouth, and the fluoride varnish will help that.  Sometimes we use a tray to carry the fluoride". One way fluoride helps is by seeping into the enamel and drawing the calcium and phosphate that's naturally present in the saliva. The minerals boost the teeth's natural healing process and make them more resistant to future decay. But there are other theories about how fluoride works. It strengthens the enamel before the tooth erupts, which is why it's so important for children. And it attacks the acid-producing bacteria in the mouth. One study shows fluoride makes it more difficult for these bacteria to stick to the teeth. It takes about a minute, and the fluoride treatment is done. Some patients are also given a prescription for a concentrated fluoride gel that can be used at night. "These preventative approaches work on adults just as well as they do on children," says Norman Tinanoff, a professor of pediatric dentistry at the University of Maryland. He says part of what's making fluoride treatments popular for adults is a move to make dental care personal, with an individual treatment plan for each patient. To do that, you have to weigh a patient's risk of getting cavities. One of the biggest proponents of this approach is John Featherstone, dean of the University of California, San Francisco School of Dentistry. Featherstone came up with a comprehensive way of measuring a person's risk for caries, or tooth decay. It includes testing the level of bacteria in the mouth, and looking at dietary habits, medical conditions, medications, saliva flow and history of tooth decay. When Featherstone put his patients on personal treatment plans, he found the strategy worked. "It really proved that drilling and filling did not fix the disease," Featherstone says. "Putting in a filling fixes that hole in the tooth, but it doesn't deal with the bacteria in the rest of the mouth." Most bacteria are friendly, but a couple of bad actors can cause cavities. These guys feed on sugars and expel acid that eats away at the enamel. Traditionally, dentists were taught that the only way to deal with decay was to drill it out. That's still important in some cases, Featherstone says, but without fixing the underlying problem of bad bacteria, patients just keep coming back for more fillings. Featherstone saw another way. "It's a little bit like your car is starting to rust," he says. "If you can stop the rust before the rust goes right through the body of the car, then you're in good shape." Like rust, tooth decay is a slow process. A full-on cavity is a hole that needs to be fixed. But if you catch decay early, Featherstone says, it can be reversed using fluoride treatments like varnish and concentrated toothpaste and gels. "In the past we believed tooth decay was a rapidly progressive disease. But research shows it's slowly progressive," says Wendell Evans, associate professor of dentistry at the University of Sydney in Australia. He recently published a study that found using these techniques reduced the need for fillings in adults by 30 to 50 percent. Striking as these results seem, the concept isn't new. This shift to a preventive model of dentistry is decades in the making. "Some of the stuff in our study has been known for 50 years," Evans says, referring to the use of fluoride treatments. "Prevention has always been a part of the world of dentistry," says Richard Valachovic, president of the American Dental Education Association. "What we're seeing is a generational shift," Valachovic says. As dentists have come to better understand the microbiology of the mouth, more effective preventive techniques have followed. At this point, Featherstone says, two-thirds of dental schools in the U.S. teach some kind of disease management model based on a thorough risk assessment. And he expects that at some point all dentists will follow a preventive protocol.  "It will happen," Featherstone says. "It's just a matter of time."

Antidepressants & Dental Implants

For a lot of people, antidepressants are life-changing, and there's no shame in taking them to take care of yourself. But according to Dr. Ryne Johnson, prosthodontist and managing partner of Newton Wellesley Dental Partners, they might have some unexpected side effects — including messing with your dental implants, new research suggests. Dr. Johnson, who has been called a pioneer in computer-assisted, implant prosthodontics wants patients to know of this correlation. Project1 The study, to be presented at the upcoming conference for the American Association for Dental Research, included 74 participants who all received dental implants during the course of the study. All of the participants were at least 18 years old, and they'd all gotten their implants at the University of Buffalo postdoctoral dental clinic between January and August of 2014. A dental implant is an artificial tooth that your dentist can place into your jaw if you lose a tooth to decay or injury. What's supposed to happen is new bone forms around the implant to secure it in place. But when the researchers went back and looked at the medical information for those 74 people, they found that those who were taking antidepressants — but not necessarily those who were currently suffering from depression symptoms — were more likely to have an implant failure than those who weren't taking the drugs. Among those who did have implant failures, 33% of participants reported taking at least one antidepressant drug. However, among those who didn't have any problems with their implants, only 11% took antidepressants. It's important to note that this is a small preliminary study, but this isn't the first time antidepressants have been linked to problems with bones and teeth. A 2007 study published in the Archives of Internal Medicine found that antidepressants could speed up bone loss in older women. And way back in 2003, another study in the Journal of the American Dental Association found that many dental patients are given medications that may interfere with their antidepressants, possibly creating an environment for tooth problems. Researchers think that because these drugs often act on our serotonin receptors, which are important for both our moods and our bones, they may be doing some damage under the radar. Still, this isn't a reason to start skipping your much-needed meds — but it's always a great idea to touch base with your doctor about side effects.   For more information about implants, Dr. Johnson, or other blog topics, visit: www.NewtonWellesleyDentalPartners.com   Original article: refinery29.com Artwork: backhealthforyou.com
