Fluoride is a critical weapon in the war against tooth decay. But this natural chemical proven to strengthen tooth enamel has also aroused suspicion over the years that it might cause health problems.
These suspicions have led to rigorous testing of fluoride's safety. And the verdict from decades of research? We've found only one verifiable side effect, a condition called enamel fluorosis. Caused by too much fluoride present in the body, enamel fluorosis produces white streaks and patches on teeth, and can develop into darker staining and pitting in extreme cases. But other than having an unattractive appearance, the teeth remain sound and healthy.
Fortunately, you can reduce the risk of fluorosis by limiting fluoride exposure to within recommended limits. Fluoride can show up in processed foods and other substances, but the two sources you should focus on most are oral hygiene products and fluoridated drinking water.
Dentists highly recommend using toothpaste with fluoride to fight tooth decay. But be careful how much your family uses, especially younger members. An infant only needs a slight smear of toothpaste on their brush for effective hygiene. At around age 2, you can increase the amount to about the size of a vegetable pea.
As to drinking water, most utilities add fluoride to their supply. If yours does, you can find out how much they add by calling them or visiting cdc.gov ("My Water's Fluoride"), where you can also learn more about recommended levels of fluoridation. If you think it's excessive, you can switch to water labeled "de-ionized," "purified," "demineralized," or "distilled," which contain little to no added fluoride.
Even if your fluoridated water is within recommended levels, you may wish to take extra precautions for infants nursing with formula. If possible, use "ready-to-feed" formula, which usually contains very low amounts of fluoride if any. If you're using the powdered form, use only water with the aforementioned labeling for mixing.
Before making any drastic changes that might affect your family's fluoride intake, consult with your dentist first. And be sure you're keeping up regular dental visits—your dentist may be able to detect any early signs of fluorosis before it becomes a bigger problem.

Every year U.S. dentists perform around 25 million root canal treatments and save countless teeth from the ravages of decay. But if you search "root canal" on the Internet, you might encounter an unsettling charge against this tooth-saving treatment—that it causes cancer.
Root canal treatments are routinely used when tooth decay has infected the pulp, the innermost layer of a tooth. During the procedure, we access the pulp and remove all the infected tissue. We then fill the empty pulp and root canals, seal the access hole and later crown the tooth to prevent further infection. Without this intervention, the decay can continue to advance toward the roots and supporting bone, putting the tooth in imminent danger of loss.
So, is there any credibility to this claim that root canal treatments cause cancer? In a word, no: there's no evidence of any connection between root canal treatments and cancer—or any other disease for that matter. On the contrary: root canals stop disease.
As with other types of urban legends and internet hype, the root canal-cancer connection may have arisen from another discredited idea from the early 20th Century. A dentist named Weston Price promoted the notion that leaving a "dead" organ in the body led to health problems. From his perspective, a root canaled tooth with its removed pulp tissue fit this criterion.
In the mid-1950s, dentistry thoroughly examined Dr. Weston's theory pertaining to treatments like root canals. The Journal of the American Dental Association devoted an entire issue to it and found after rigorous scientific inquiry that the theory had no validity in this regard. Another study in 2013 confirmed those findings. In fact, the later study instead found that patients who underwent a root canal treatment had a 45 percent reduction in oral cancer risk.
Given the freewheeling nature of the Internet, it's best to speak with a dental professional about your oral health before trusting a post or article you've found online. Not only are they more informed than an unverified online source, they would certainly not knowingly subject you to a procedure to save a tooth at the expense of your health.

Are bleeding gums something you should be concerned about? Dear Doctor magazine recently posed that question to Dr. Travis Stork, an emergency room physician and host of the syndicated TV show The Doctors. He answered with two questions of his own: “If you started bleeding from your eyeball, would you seek medical attention?” Needless to say, most everyone would. “So,” he asked, “why is it that when we bleed all the time when we floss that we think it’s no big deal?” As it turns out, that’s an excellent question — and one that’s often misunderstood.
First of all, let’s clarify what we mean by “bleeding all the time.” As many as 90 percent of people occasionally experience bleeding gums when they clean their teeth — particularly if they don’t do it often, or are just starting a flossing routine. But if your gums bleed regularly when you brush or floss, it almost certainly means there’s a problem. Many think bleeding gums is a sign they are brushing too hard; this is possible, but unlikely. It’s much more probable that irritated and bleeding gums are a sign of periodontal (gum) disease.
How common is this malady? According to the U.S. Centers for Disease Control, nearly half of allÂ Americans over age 30 have mild, moderate or severe gum disease — and that number increases to 70.1 percent for those over 65! Periodontal disease can occur when a bacteria-rich biofilm in the mouth (also called plaque) is allowed to build up on tooth and gum surfaces. Plaque causes the gums to become inflamed, as the immune system responds to the bacteria. Eventually, this can cause gum tissue to pull away from the teeth, forming bacteria-filled “pockets” under the gum surface. If left untreated, it can lead to more serious infection, and even tooth loss.
What should you do if your gums bleed regularly when brushing or flossing? The first step is to come in for a thorough examination. In combination with a regular oral exam (and possibly x-rays or other diagnostic tests), a simple (and painless) instrument called a periodontal probe can be used to determine how far any periodontal disease may have progressed. Armed with this information, we can determine the most effective way to fight the battle against gum disease.
Above all, don’t wait too long to come in for an exam! As Dr. Stork notes, bleeding gums are “a sign that things aren’t quite right.” Â If you would like more information about bleeding gums, please contact us or schedule an appointment.
