A popular Sixties-era hair cream touted their product with the tagline, "A little dab'll do ya!" In other words, it didn't take much to make your hair look awesome.
Something similar could be said about fluoride. Tiny amounts of this "wonder" chemical in hygiene products and drinking water are widely credited with giving people a big boost in protection against tooth decay.
A Colorado dentist is credited with first noticing fluoride's beneficial effects early in the Twentieth Century. Although many of his patients' teeth had brownish staining (more about that in a moment), he also noticed they had a low incidence of cavities. He soon traced the effect to fluoride naturally occurring in their drinking water.
Fast forward to today, and fluoride is routinely added in trace amounts to dental care products and by water utilities to the drinking water supply. It's discovery and application have been heralded as one of the top public health successes of the Twentieth Century.
Fluoride, though, seems a little too amazing for some. Over its history of use in dental care, critics of fluoride have argued the chemical contributes to severe health problems like low IQ, cancer or birth defects.
But after several decades of study, the only documented health risk posed by fluoride is a condition called fluorosis, a form of staining that gives the teeth a brown, mottled appearance (remember our Colorado residents?). It's mainly a cosmetic problem, however, and poses no substantial threat to a person's oral or general health.
And, it's easily prevented. Since it's caused by too much fluoride in prolonged contact with the teeth, fluorosis can be avoided by limiting fluoride intake to the minimum necessary to be effective. Along these lines, the U.S. Public Health Service recently reduced its recommended amounts added to drinking water 0.7 milligrams per liter (mg/L) of water. Evidence indicated fluoride's effectiveness even at these lower amounts.
You may also want to talk with your dentist about how much fluoride your family is ingesting, including from hidden sources like certain foods, infant formula or bottled water. Even if you need to reduce your family's intake of fluoride, though, a little in your life can help keep your family's teeth in good health.

For several decades, dentists have been saving teeth from tooth decay following a few basic guidelines: 1) Identify decay as soon as possible; 2) Thoroughly remove decayed tooth structure; and 3) Fill any cavities. With millions of diseased teeth rescued, observing these simple steps have proven a rousing success.
But as with most things, even this successful protocol isn't perfect. For one, some healthy tissue gets removed along with the diseased portions. The average percentage of "collateral damage" has dropped over the years, but it still happens—and a reduction in healthy tissue can make a tooth less structurally sound.
Another drawback, at least from the patient's perspective, is the dental drill used for removing decay and preparing cavities for filling. Many people find drilling unpleasant, whether from its vibrations in the mouth or its high-pitched whine. The drill's burr head design also contributes to greater healthy tissue loss.
But those weaknesses have lessened over the last few years, thanks to innovations on a number of fronts.
Better risk management. Tooth decay doesn't occur out of thin air—it arises out of risk factors unique to an individual patient like personal hygiene, bacterial load, saliva production or even genetics. Taking the time to identify a patient's "tooth decay risk score" can lead to customized treatments and practices that can minimize the occurrence of decay.
Earlier detection. Like other aspects of dental health, the sooner we detect decay, the less damage it causes and the more successful our treatment. X-rays remain the workhorse for detecting decay, but now with improvements like digital film and better equipment. We're also using newer technologies like laser fluorescence and infrared technology that can "see" decay that might otherwise go undetected.
Less invasive treatment. The dental drill is now being used less with the advent of air abrasion technology. Air abrasion utilizes a concentrated spray of particles to remove diseased tooth structure more precisely than drilling. That means less healthy tissue loss—and a more pleasant (and quieter!) experience for the patient.
In effect, "less is more" could describe these improvements to traditional decay treatment. They and other methods promise healthier teeth and happier patients.

As summer wanes, thousands of high school grads will begin the new adventure called college. For many of these "freshmen," it will also be their first taste of true independence—mom and dad and the guidance they normally provide will be far away.
This is generally a good thing. But there are also consequences to making (or not making) your own choices that can have long-lasting effects, some of which may not be pleasant. For example, neglecting teeth and gum care could disrupt oral health (as well as overall health) for years or even decades to come.
As your newly minted college student sets off on their new academic journey, be sure that among the advice you give them are these 3 important dental care habits.
Brush and floss daily. It's important to stress that among the things of childhood to leave behind, oral hygiene isn't one of them. Dental disease is mainly caused by dental plaque, a thin bacterial film that accumulates on teeth. Removing plaque daily with brushing and flossing greatly reduces disease risk. It's a top priority, even with a hectic college schedule.
Eat "tooth-friendly." That hectic schedule may also tempt them to grab whatever food is quick and available. Unfortunately, such food isn't always the healthiest, especially for teeth and gums. Foods and snacks loaded with sugar are especially perilous to oral health—sugar feeds the bacteria that cause tooth decay and gum disease. Healthier food choices contribute to healthier teeth and gums.
Avoid bad habits. The exhilaration of new independence can lead to a flurry of bad habits, some of which could affect teeth and gum health. Using tobacco increases the risk of dental disease and oral cancer. Wearing lip piercings or tongue jewelry may cause tooth damage. And certain forms of unprotected sex raise the chances of viral infection and an increased risk of oral cancer.
College can be an exciting adventure. But there are pitfalls along the way, especially for oral health. Advising your college student to follow these tips will help ensure their teeth and gums stay healthy beyond graduation.
