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.

The Internet is truly amazing: It takes only a few seconds to tap into a vast store of knowledge to find information that once took people hours or days. But amidst all that helpful data, there's also some not so helpful information—in fact, some can be downright harmful, including to your dental health.
One particular Internet trend is brushing teeth with black, gooey substances containing activated charcoal. Scores of online videos featuring people doing this are getting viral views, perhaps more for the “gross” factor than the claimed health benefits.
So, why do it? Advocates of using activated charcoal for oral hygiene claim the ingredient kills harmful microorganisms in your mouth. The charcoal is also supposed to whiten your teeth.
But clinical studies of the practice, including one recently published in the Journal of the American Dental Association have been unable to substantiate these claims. There's simply no evidence that activated charcoal does what its advocates say it can do.
Unfortunately, there is evidence the practice can actually harm your teeth. This is because activated charcoal is an abrasive substance that over time could damage your teeth's enamel. Eroded enamel doesn't regrow, so eventually the more vulnerable dentin, the tooth layer just beneath the protective enamel, becomes exposed. It's not only darker and less attractive than enamel, its more susceptible to tooth decay and cavities.
The best way to care for your teeth, brushing and flossing daily, may seem boring compared to videos of brushing with charcoal, but it is effective—and safe. You should also see your dentist for more thorough cleanings at least every six months to round out your dental care.
And if you want a brighter smile, your dentist can perform a tooth whitening procedure that can give you months or even years of satisfaction. Professional tooth whitening (or even home whitening kits applied properly) also won't harm your enamel.
Chipped a tooth? Don't beat yourself up—this type of dental injury is quite common. In fact, you probably have a favorite celebrity who has chipped one or more of their teeth. The list is fairly long.
Some chipped a tooth away from the limelight, such as Tom Cruise (a hockey puck to the face as a teen), Jim Carrey (roughhousing on the playground) and Paul McCartney (a sudden stop with a moped). Others, though, chipped a tooth while “on the job.” Taylor Swift, Hillary Duff and Jennifer Lopez have all chipped a tooth on stage with a microphone. And chipped teeth seem to be an occupational hazard among professional athletes like former NFL star, Jerry Rice.
Since smiles are an indispensable asset to high-profile celebrities, you can be sure these stars have had those chipped teeth restored. The good news is the same procedures they've undergone are readily available for anyone. The two most common restorations for chipped teeth are dental bonding and veneers.
The least invasive way to fix a chipped tooth is bonding with a material known as composite resin. With this technique, resin is first mixed to match the tooth color and then applied to the chipped area or applied in layers of color to get just the right look. After a bit of shaping, curing and adjustment, we're done—you can walk out with a restored tooth in one visit.
Bonding works well with slight to moderate chips, but it could be less durable when there is more extensive damage. For that, you may want to consider porcelain veneers. Veneers are thin wafers of dental porcelain that are bonded to the front of teeth to mask blemishes like stains, slight gaps or, yes, chips. Veneers can be so lifelike that you won't be able to tell the veneered tooth from your other teeth. They are fashioned to match the color and shape of an individual's teeth. Because of the time and design detail involved, veneers are more expensive than bonding, yet still within an affordable range for many.
Teeth require some alteration before applying traditional veneers because otherwise the teeth can appear bulky when the veneer is bonded to the existing tooth. To compensate, we remove a little of the tooth enamel. Because this loss is permanent, you'll need to wear veneers or have some other form of restoration for the tooth from then on. For many people, though, that's a small price to pay for a smile without chips.
Your first step to repairing a chipped tooth is to come in for an examination. From there, we'll recommend the best option for your situation. And regardless of which, bonding or veneers, we can change your smile for the better.
