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.

Everyone loves a concert where there's plenty of audience participation… until it starts to get out of hand.Â Recently, the platinum-selling band Fifth Harmony was playing to a packed house in Atlanta when things went awry for vocalist Camila Cabello. Fans were batting around a big plastic ball, and one unfortunate swing sent the ball hurtling toward the stage — and directly into Cabello's face. Pushing the microphone into her mouth, it left the “Worth It” singer with a chipped front tooth.
Ouch! Cabello finished the show nevertheless, and didn't seem too upset. “Atlanta… u wild… love u,” she tweeted later that night. “Gotta get it fixed now tho lol.” Fortunately, dentistry offers a number of ways to make that chipped tooth look as good as new.
A small chip at the edge of the tooth can sometimes be polished with dental instruments to remove the sharp edges. If it's a little bigger, a procedure called dental bonding may be recommended. Here, the missing part is filled in with a mixture of plastic resin and glass fillers, which are then cured (hardened) with a special light. The tooth-colored bonding material provides a tough, lifelike restoration that's hard to tell apart from your natural teeth. While bonding can be performed in just one office visit, the material can stain over time and may eventually need to be replaced.
Porcelain veneers are a more long-lasting solution. These wafer-thin coverings go over the entire front surface of the tooth, and can resolve a number of defects — including chips, discoloration, and even minor size or spacing irregularities. You can get a single veneer or have your whole smile redone, in shades ranging from a pearly luster to an ultra-bright white; that's why veneers are a favorite of Hollywood stars. Getting veneers is a procedure that takes several office visits, but the beautiful results can last for many years.
If a chip or crack extends into the inner part of a tooth, you'll probably need a crown (or cap) to restore the tooth's function and appearance. As long as the roots are healthy, the entire part of the tooth above the gum line can be replaced with a natural-looking restoration. You may also need a root canal to remove the damaged pulp material and prevent infection if the fracture went too far. While small chips or cracks aren't usually an emergency (unless accompanied by pain), damage to the tooth's pulp requires prompt attention.

Braces are a common experience among teens and pre-teens. And although the treatment can be a major financial undertaking, more and more families pursue it to help their child attain a straighter, more attractive smile.
But orthodontics isn’t first and foremost a cosmetic treatment. Although an improved appearance is a benefit, the main reason for treatment is therapeutic—it can improve your child’s current and future dental health.
The teeth’s relationship to the jaws and gums makes moving them possible. Rather than simply being fixed within their jawbone socket, teeth are actually held in place by a strong, elastic tissue called the periodontal ligament. The ligament lies between the teeth and jawbone and attaches to both with tiny extending fibers. This attachment secures the teeth in place.
But the ligament also has a dynamic quality—it can reshape itself when necessary and allow teeth to move gradually into new positions. This is most necessary during the early years of mouth and jaw development, but it can also occur throughout life. Orthodontics takes advantage of this mechanism by applying precise pressure to the teeth in the direction of desired movement. The periodontal ligament does the rest by reshaping and allowing the teeth to move in response to this pressure.
The result is straighter teeth and a more normal bite. With the teeth now where they should be, it’s also easier to clean them of disease-causing dental plaque, whereas misaligned teeth are more prone to plaque accumulation that can be difficult to remove. And because the whole mouth including teeth are involved when we talk, teeth positioned in a more normal bite will improve speech.
Orthodontics is a long-term process, often encompassing more than the actual time wearing braces. Both orthodontists and pediatric dentists recommend a bite evaluation by an orthodontist around the age of 6. If it does appear an abnormal bite is forming, it may be possible to intervene and stop or at least slow the development. This could have a more positive impact on any future treatment.
Braces and other treatments can make a difference in your child’s self-image and social relationships. But the main beneficiary will be their dental health.
