Women are 33 percent more likely receive preventive dental care, such as regular checkups, than men are, according to a new study looking at preventive dental care rates among different groups.


The study, published in the journal Frontiers in Public Health[1] , also shows -- unsurprisingly -- that people with health insurance are 138 percent more likely to receive preventive dental care [2] than people without.


Among racial groups, Asian Americans and Caucasians are the most likely to receive preventive dental care, with 77 percent and 76 percent receiving such care in 2008, respectively. Meanwhile, 62 percent of Hispanics, 62 percent of Native Americans and 57 percent of African Americans received preventive dental care in 2008.


The study, conducted by Duke University researchers, is based on phone survey responses from nearly 650,000 middle-aged and elderly people in the U.S. between 1999 and 2008. The participants were asked the last time a professional cleaned their teeth (considering an indicator of preventive dental care).


Researchers found that more Americans have been receiving preventive dental care each year for the last 10 years, though there is still a large number -- 23 to 43 percent, depending on the racial group -- going without such care.


Smokers were also found to be less likely than non-smokers to receive preventive dental care.

  • Dried Fruits


    While dried fruits may be a definite <a href="http://www.huffingtonpost.com/2012/02/28/fruit-chew-snacks-ingredients_n_1304369.html">step up from processed fruit snacks</a>, they are still sticky and high in sugar. That means they not only adhere to teeth easily, but the sugar feeds the bacteria in the mouth, which can promote dental erosion, notes Joy Dubost, Ph.D., R.D., a spokesperson for the American Academy of Nutrition and Dietetics. "I'm not saying don't eat them, but just brush your teeth afterward," Dubost says. Messina adds that regular fresh fruits don't typically have this problem because -- even though they still have sugar -- chewing them up promotes saliva and they don't stick to the teeth. "Fruits are generally pretty safe because they're good for overall health <em>and</em> they're chewy, so your average fruit has some substance to it and we chew through it, causing us to salivate more," Messina says. "Saliva is a good thing because it has washing action and it's a nautral buffer [to] acid."




  • Sugary Drinks


    Sugary drinks, such as sodas and sports drinks, are especially bad for teeth when sipping for long periods of time. "If I have a soft drink or sports drink and I'm sipping it every 20 minutes, my teeth are getting bathed with a constant layer of acid," Messina says. "So sitting down and drinking it all at once, or with a meal, is better than snacking or sipping throughout a meal." For this reason, Dubost recommends that parents don't fill their kids' sippy cups with sugary drinks, since kids, whose teeth are still developing, tend to sip at those drinks over long periods of time.




  • Hard Candies


    For the same reason sipping on sodas all day is bad for teeth, hard candies aren't ideal for oral health, Dubost notes. These sweets pack a double whammy in that they not only stick to the teeth, but they also linger in the mouth for a long time as you wait for them to dissolve.




  • Alcohol


    You may not realize it, but alcohol can be bad for the teeth, as it causes <a href="http://www.yalemedicalgroup.org/stw/Page.asp?PageID=STW001565">natural saliva production</a> to decrease, according to the Yale Medical Group. And again, saliva helps to wash away food particles and provides a buffer against acid. People who are alcoholics may <a href="http://www.thefix.com/content/sober-teeth?page=all">experience dental and gum disease</a> since "alcohol irritates all the soft tissue in the mouth and it decreases the amount of natural saliva," Dr. Parimal Nagjee, a dentist in Beverly Hills, <a href="http://www.thefix.com/content/sober-teeth?page=all">told The Fix</a>. "In terms of the tissue, the skin of the mouth is very delicate and the alcohol is corrosive to the gums, cheeks and skin. It can affect the way the tissue cells divide, which is why people who drink heavily have a greater chance of getting mouth or throat cancer.”




  • Citrus/Acidic Foods


    Foods high in acid, such as citrus or tomatoes, can promote tooth decay, especially when eaten alone, Dubost notes. But these foods are fine to eat so long as you flush your mouth with water after consuming them in order to buffer the acid. Citrus not only has acid, but also sugar -- and people who have a habit of sucking on lemons or limes are actually harmfully bathing their teeth in acid, Messina says. "If you look in their mouths, their teeth have a shiny, glossy surface -- that's from constant bathing with the acids," he says. "They will have almost a peculiar look in that you'll see it on the front surfaces of their teeth, but not the back sides of the lower front teeth because those are under the tongue -- and the tongue protects the surface of teeth."




  • Starchy Foods


    Starchy foods, such as potato chips and white bread, easily get trapped in teeth, which can then <a href="http://www.yalemedicalgroup.org/stw/Page.asp?PageID=STW001565">feed the bacteria</a> that make up plaque, according to the Yale Medical Group.




  • Coffee


    Not only do drinks like coffee and tea stain the teeth, they also make the teeth stickier -- meaning more food particles can latch on, Messina says.
