The U.S. Centers for Disease Control and Prevention calls it “one of the ten most important public health measures of the 20th Century.” A new vaccine? A cure for a major disease? No—the CDC is referring to the addition of fluoride to drinking water to prevent tooth decay.
Fluoride is a chemical compound found in foods, soil and water. Its presence in the latter, in fact, was key to the discovery of its dental benefits in the early 20th Century. A dentist in Colorado Springs, Colorado, whose natural water sources were abundant with fluoride, noticed his patients' teeth had unusual staining but no tooth decay. Curious, he did some detective work and found fluoride in drinking water to be the common denominator.
By mid-century, fluoride was generally recognized as a cavity fighter. But it also had its critics (still lively today) that believed it might also cause serious health problems. Ongoing studies, however, found that fluoride in tiny amounts—as small as a grain of sand in a gallon of water—had an immense effect strengthening enamel with scant risk to health.
The only condition found caused by excess fluoride is a form of tooth staining called fluorosis (like those in Colorado Springs). Fluorosis doesn't harm the teeth and is at worst a cosmetic problem. And it can be avoided by regulating the amount of ingested fluoride to just enough for effectively preventing tooth decay.
As researchers have continued to learn more about fluoride, we've fine-tuned what that amount should be. The U.S. Public Health Service (PHS), which sets standards for fluoride in drinking water, now recommends to utilities that fluoridate water to do so at a ratio of 0.7 mg of fluoride to 1 liter of water. This miniscule amount is even lower than previous recommendations.
The bottom line: Fluoride can have an immense impact on your family's dental health—and it doesn't take much. Excessive amounts, though, can lead to dental staining, so it's prudent to monitor your intake. That means speaking with your dentist about the prevalence of fluoride in your area (including your drinking water) and whether you need to take measures to reduce (or expand) your use of it.

Most of what goes on inside our mouths—good or bad—is fairly predictable. But every now and then, people encounter something out of the ordinary. A good example is lichen planus.
Lichen planus are rare skin lesions that can occur on various parts of the skin, including inside the mouth. The name comes from their lacy appearance, which resembles a fungus that grows on rocks or trees called lichen.
Being similar in appearance, though, is all that lichen planus has in common with its fungal namesake. It's believed that the sores are caused by a reaction of the immune system mistaking some of the body's cells as foreign.
But don't let the exotic sounding name alarm you—true lichen planus is considered a benign mouth sore. You may not even realize you have it until your dentist notices and points it out. But the lesions can sometimes cause mild pain or burning, especially if they occur near the gums or if you indulge in spicy or acidic foods.
As we said, these lesions aren't considered dangerous. But in a small number of cases, oral cancer was found to develop later. It's unclear whether the lesions were related to the cancer, or if what were diagnosed as lichen planus lesions were actually pre-cancerous cells mimicking the appearance of the benign sore.
In any event, your dentist will probably continue to monitor the lesions and possibly conduct regular oral cancer screenings to be on the safe side. You may also want to stop using tobacco or alcohol products to further decrease your risk of oral cancer.
As to managing lichen planus, it starts with a daily habit of brushing and flossing. You'll also want to avoid spicy or acidic foods like citrus fruits, tomatoes, peppers or caffeinated drinks, especially during flareups. If the lesions are causing discomfort, your dentist may also prescribe a topical steroid to apply to them.
Since it's quite possible you won't know if you have lichen planus (as well as other types of mouth sores) unless your dentist observes them, you should keep up regular dental visits. Having your dentist check your entire mouth, not just your teeth and gums, will help both of you stay on top of your oral health.

While your dentist plays an important role in keeping things inside your mouth healthy, what you do every day often makes the biggest difference. Here are 5 routine things you can do for better oral health.
Brush and floss every day. The most important thing you can do for your teeth and gums is adhere to a daily schedule of brushing and flossing. These twin tasks remove the daily buildup of plaque, a thin bacterial biofilm most responsible for tooth decay and gum disease.
Check your hygiene. There's brushing and flossing—and then there's brushing and flossing effectively. To make sure you're getting the job done, run the tip of your tongue along your teeth after you brush and floss. If it feels smooth, mission accomplished! If it feels rough and gritty, though, try again. You can also use plaque disclosure products occasionally to highlight any missed plaque still on your teeth.
Say no to sugar. Chances are you love sugar—and so do the disease-causing bacteria in your mouth. As they feed on sugar, they multiply and produce acid, which in high levels can erode tooth enamel and lead to tooth decay. Limiting sugar in your diet reduces oral bacteria and the acid they produce, and thus lowers your risk for disease.
Drink plenty of water. Saliva plays an important role in oral health: It helps fight off bacteria, neutralizes acid and re-mineralizes tooth enamel. But it can't do those things if there's not enough of it. So, if your mouth consistently feels dry, drink more water to give your body what it needs to make saliva. Drinking water also washes away food particles that could become plaque and lowers your mouth's acidity.
Maintain your dental appliances. You can extend the life of dentures, retainers or other types of dental appliances by cleaning and maintaining them. You should clean your appliance regularly using regular hand soap or a designated cleaner (not toothpaste, which can be too abrasive). Unless otherwise directed by your dentist, take them out at night and be sure to store them where kids or pets can't get to them.
