We can easily take for granted the comfort we now experience when we undergo dental work. For much of human history that hasn't been the case.
Local anesthesia has been a major factor in the evolution of pain-free dentistry. The term refers to the numbing of nerve sensation in the tissues involved in a procedure. This type of anesthesia is usually applied in two ways: topical and injectable.
We apply topical anesthetic agents to the top layers of tissue using a cotton swab, adhesive patch or a spray. Topical agents are useful for increasing comfort during cleanings for patients with sensitive teeth or similar superficial procedures. Topical anesthesia is also used in conjunction with injections as a way to prevent feeling the minor prick of the needle. In essence, you shouldn't feel any pain or discomfort from beginning to end of your procedure.
Injectable anesthesia deadens pain at deeper levels of tissue. This makes it possible for us to perform more invasive procedures like tooth extraction or gum surgery without using general anesthesia. The latter form is a more intense undertaking: it renders you unconscious and may require assistance for lung and heart function.
Most important of all, subtracting pain sensation from the procedure helps relieve stress: first for you and ultimately for us. If we know you're comfortable, we can relax and concentrate on the work at hand. The procedure goes much more smoothly and efficiently.
Many people, though, have concerns about how long the numbness will linger after the procedure. This has been viewed in the past as an annoying inconvenience. But in recent years, dentists have become more adept at fine-tuning the agents they use as a way to reduce post-procedure numbness. There's also promising research on chemical agents that can quickly reverse the numbing effect after a procedure.
All in all, though, using local anesthesia broadens the range of dental work we can perform without putting you to sleep. More importantly, you'll be able to relax as we perform procedures that could improve your dental health for years to come.
Since the 1950s fluoride has played an important role in the fight against tooth decay as an additive to hygiene products and many public water supplies. But although a proven cavity fighter, some have questioned its safety over the years.
To date, though, the only substantiated health risk from fluoride use is a condition known as enamel fluorosis, which occurs when too much fluoride is ingested during early tooth development as the mineral embeds in the tooth structure. Fluorosis can cause changes in the enamel’s appearance, ranging from barely noticeable white streaking to darker visible staining and a pitted texture.
Fluorosis is primarily a cosmetic problem and not a serious health issue. The staining on otherwise sound teeth, however, is permanent and more severe cases may require extensive bleaching treatment to improve appearance. The best strategy is to prevent fluorosis by monitoring and limiting your child’s fluoride intake, until about age 9.
Tooth decay is a more serious condition than fluorosis so we’re not advocating you eliminate fluoride but that you keep your family’s intake within safe levels. The first step is to determine just how much that intake is now, particularly if you drink fluoridated water. If you have public water, you may be able to find its fluoridation level online at apps.nccd.cdc.gov or call the utility directly.
You should also be careful about the amount of toothpaste your child uses to brush their teeth. Children under two need only a trace (a “smear”) on the brush, and children between the ages of 2 and 6 a pea-sized amount. And, they should brush no more than twice a day.
Another possible concern is infant formula, especially mixable powder. While the formula itself doesn’t contain fluoride, water mixed with it may. If you live in an area with increased fluorosis risk, consider breast-feeding (breast milk has little fluoride), using ready-to-feed formula, or mixing powdered formula with bottled water labeled “de-ionized,” “purified,” “demineralized” or “distilled.”
We’ll be glad to help assess your family’s current fluoride intake and advise you on making adjustments to bring it into normal ranges. Taking in the right amount of fluoride assures you and your children receive the most benefit and protection from it, while avoiding future smile problems.

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.
