Guidelines regarding the concentration of fluoride in water have recently been changed by the US Government's Department of Health and Human Services (HHS) and the Environmental Protection Agency (EPA). These agencies recommended a reduction of fluoride in water supplies to 0.7mg/L, modifying the original recommendations provided in 1962 by the US Public Health Service.
What is fluoride, and why add it to water supplies?
Fluoride is a chemical form of fluorine, a naturally occurring element. For decades, scientists have carried out studies on the effects of fluoride in water, and they have proved that fluoride strengthens tooth surfaces and makes them resistant to decay. A fluoride concentration of about one milligram per liter (1 mg/L), or 1 part per million (1ppm), in the water supply is associated with substantially fewer cavities. This concentration of fluoride (equivalent to a grain of salt in a gallon of water) has been found to have no negative health effects.
The Center for Disease Control (CDC) says that fluoridated water is one of the ten most effective public health measures of the 20th Century. The optimal amount of fluoride necessary to make teeth resistant to decay turns out to be between 0.7 and 1.20 milligrams per liter (mg/L). A certain amount of fluoride occurs naturally in water supplies, and communities have added fluoride to bring the amount up to the optimal recommendations.
How does fluoride you drink get into your teeth?
The fluoride you drink in your water is deposited in your bones. Bone is an active living substance that is constantly broken down and rebuilt as a normal body process. As this happens the fluoride is released into the blood, from which it can enter the saliva and act on the tooth surface.
What about fluoride from other sources?
Americans now have access to many sources of fluoride in addition to the water they drink. These include foods, beverages and toothpaste. As a result, dentists have begun to notice an increased prevalence of a condition known as Dental Fluorosis.
What is Dental Fluorosis?
Dental Fluorosis can occur when teeth, particularly in children, receive too much fluoride. This condition is a mottling or uneven staining of the tooth surface enamel. There may be small white spots or extensive brownish discolorations. The mottled enamel is still resistant to decay, but it may be unattractive in appearance.
What is the idea behind the new guidelines?
With the new guidelines, fluoride is kept at the lower end of the scale of the optimal concentration for strengthening teeth against decay. At this end, there is room to add consumption of fluoride from other sources such as foods or toothpaste. In short, it is the best of both worlds.

Florence Henderson is a multi-talented actress most recognized for her role as Carol Brady on The Brady Brunch, one of the longest-running situational comedies. In fact, this role earned her the title of America's Favorite TV Mom and her first TV Land Pop Culture Icon award, which is on permanent display in the National Museum of American History.
During an interview with Dear Doctor magazine, Henderson discussed her oral health as well as her role as spokesperson for Polident (denture cleanser) — even though she does not have dentures. Henderson attributes her beautiful, natural smile to prevention. “Flossing, brushing and regular dental checkups are vital if you want to keep your teeth,” she said, adding, “I always have mouthwash, dental floss, toothpaste and a toothbrush on the set.”
Similar to the great advice “Carol Brady” shared on television, Henderson's advice on oral hygiene is spot-on. We agree that an effective educational approach to oral hygiene and diet is essential to keeping teeth for a lifetime.
The first step is to ensure you have a proper brushing and flossing technique. We can go over these during your next office visit. Our goal is to ensure that you are applying the ideal amount of pressure and motion because gum tissues are soft and can easily be damaged. And you should never use a hard-bristled toothbrush or saw at your gums and teeth when brushing. The best technique is a modified, gentle scrub where you hold a well-designed, multi-tufted toothbrush at a 45-degree angle to the gum line to gently wiggle/scrub your teeth clean.
As for flossing, you should do it at least once daily to remove the plaque buildup that occurs in the protected areas between teeth where your toothbrush can't reach and where periodontal (gum) disease and dental caries (cavities) start and progress. Many people are shocked to learn that over 50% of the accumulation of plaque occurs in these areas.
To learn more about proper oral hygiene, you can continue reading the Dear Doctor magazine article “Oral Hygiene Behavior.” Or you can contact us today to schedule an appointment so that we can conduct a thorough examination and discuss what treatment options will be best for you.

Thinking or knowing you have an impacted wisdom tooth can be alarming news for some people. Unfortunately, one of the main reasons for this feeling is due to the mythology surrounding wisdom teeth...and especially impacted wisdom teeth. While an impacted wisdom tooth can cause intense pain, some people are quite shocked to learn that they even have impacted wisdom teeth, as it is causing no pain at all.
By definition, an impacted wisdom tooth is a third (and last) molar that gets jammed against an adjacent tooth or other important structures such as gum, bone nerves, blood vessels. And having an impacted wisdom tooth does have its consequences — even if you are unaware you have one. The most common issue is gum (periodontal) disease. This is the main reason why it is so important to have a problematic wisdom tooth removed early when you are young and before periodontal disease has started. If left untreated, you risk damaging and/or losing the impacted tooth and adjacent teeth.
The key to managing wisdom teeth is to monitor them closely through thorough routine examinations and x-rays between the ages of 17 and 25, the time when wisdom teeth typically appear. This is so vital because it allows us to predict the way your wisdom teeth will erupt (become visible) or come into proper position with useful biting function. We can use these visits and x-rays to monitor development so that we are best equipped to determine if or when wisdom teeth need to be treated or removed.
It is also important to contact us as soon as you think you may have an impacted wisdom tooth that is causing pain, swelling or even infection. We can put your mind at rest with the facts of what needs to be done after we've completed our exam.
If you feel that you or a family member has an impacted wisdom tooth, contact us today to schedule an appointment to discuss your questions. Or you can learn more now about the symptoms and treatment options of impacted wisdom teeth by continuing to read the Dear Doctor magazine article “Wisdom Teeth.”
