Protecting a child's primary (“baby”) teeth from tooth decay should be a top priority. If one is lost prematurely due to decay, it could cause the permanent tooth to misalign when it comes in.
The basic prevention strategy for every child is daily brushing and flossing and regular dental visits. But children at higher risk for decay may need more: Â additional fluoride applied to teeth enamel during office visits.
This natural mineral has been shown to strengthen enamel, teeth's protective layer against decay, especially during its early development. Enamel is composed of calcium and phosphate minerals interwoven to form a crystalline structure called hydroxyapatite. Fluoride joins with this structure and changes it to fluorapatite, which is more resistant to mouth acid than the original structure.
We mostly receive fluoride through fluoridated drinking water and dental care products like toothpaste. Topical fluoride takes it a step further with a stronger dose than found in either of these sources. It can be applied with a foam, varnish or gel using an isolation tray (foam or gel) or painted onto the enamel (varnish or gel).
But does topical fluoride effectively reduce the occurrence of decay? Research indicates yes: a recent review of 28 studies involving over 9,000 children found an average 28% reduction in decayed teeth in children who underwent topical fluoride treatments.
There is, though, one potential side effect: children who swallow the fluoride substance can become sick and experience headache, stomach pain or vomiting. This can be avoided with proper precautions when applying it; the American Dental Association also recommends using only varnish for children younger than 6 years. It's also recommended that children receiving gel or foam not eat or drink at least thirty minutes after the treatment (those who receive the varnish aren't restricted in this way).
Topical fluoride is most effective as part of an overall prevention strategy. Besides daily hygiene and regular dental visits, you can also help reduce your child's decay risk by limiting the amount of sugar in their diet. Sealants, which are applied to the nooks and grooves of teeth where plaque can build up, may also help.
Fluoride has been proven to strengthen tooth enamel against decay. That’s why it’s not only added to toothpaste and other dental products, but also to drinking water — in nearly three-quarters of U.S. water systems.
While research has eased most serious health questions about fluoride, there remains one moderate concern. Too much fluoride over time, especially in infants and young children, could lead to “enamel fluorosis,” an excess of fluoride in the tooth structure that can cause spotting or streaking in the enamel. While often barely noticeable, some cases of fluorosis can produce dark staining and a pitted appearance. Although not a symptom of disease, fluorosis can create a long-term cosmetic concern for the person.
To minimize its occurrence, children under the age of 9 shouldn’t regularly ingest fluoride above of the recommended level of 0.70 ppm (parts per million). In practical terms, you as a parent should monitor two primary sources of fluoride intake: toothpaste and drinking water.
Young children tend to swallow toothpaste rather than spit it out after brushing, which could result in too much fluoride ingestion if the amount is too great. The American Academy of Pediatric Dentistry therefore recommends a small “smear” of toothpaste for children under two, and a pea-sized amount for children up to age six. Brushing should also be limited to no more than two times a day.
Your child or infant could also take in too much fluoride through fluoridated drinking water, especially if you’re using it to mix infant formula. You should first find out the fluoride levels in your local water system by contacting the utility or the health department. If your system is part of the U.S. Centers for Disease Control and Prevention’s (CDC) “My Water’s Fluoride” program, you may be able to access that information on line at http://apps.nccd.cdc.gov/MWF/Index.asp.
If the risk for developing fluorosis in your area is high, you can minimize your infant’s intake with a few recommendations: breastfeed rather than use formula; use “ready-to-feed” formula that doesn’t need mixing and contains lower fluoride levels; and use bottled water specifically labeled “de-ionized,” “purified,” “de-mineralized,” or “distilled.”
Fluoride can be a wonderful adjunct to dental care in reducing risk for tooth decay. Keeping an eye on how much fluoride your child takes in can also minimize the chance of future appearance problems.

As one of America's most beloved go-to guys for inspiration on the latest interior design trends, Nate Berkus has written a highly successful book, Home Rules: Transform the Place You Live Into a Place You'll Love; he is a contributing editor to O Magazine; and he is currently hosting his own television program, The Nate Berkus Show. He is also recognized for his eye-catching smile.
During a recent interview with Dear Doctor magazine, Berkus opened up about the facts behind his trademark smile. While his smile is all-natural — he never wore braces or had any cosmetic work done — he gives credit to his childhood dentist for the preventative healthcare he received as a young boy. “I'm grateful for having been given fluoride treatments and sealants as a child,” he said. Nate also shared the important flossing advice he learned from his dentist that he still follows today: “Floss the ones you want to keep.”
Why is flossing so important?
Flossing is crucial because it remains the most effective method for removing plaque from between teeth, where the toothbrush can't reach. It is also an important part of keeping your gums healthy so that you can avoid periodontitis (gum disease). You should floss at least once a day either before or after you brush your teeth. If you see blood after flossing, it may indicate that you have periodontitis, or it may mean that you are flossing too harshly. Remember, you need to use a delicate hand and a proper technique when brushing and flossing to avoid damaging your teeth and gums.
To learn more about flossing, including step-by-step instructions with photos, you can continue reading the Dear Doctor magazine article “Flossing — A Different Approach.” Or you can contact us today to schedule an appointment so that we can conduct a thorough examination, review your brushing and flossing techniques, and discuss any questions you have as well as treatment options. As needed, we will work with you to teach you the proper brushing and flossing techniques so that you feel confident before you leave our office.

In the early 1900s, a Colorado dentist noticed many of his patients had unusual brown staining on their teeth — and little to no tooth decay. What he unknowingly observed was the power of a chemical substance in his patients' drinking water — fluoride. While commonplace today, fluoride sparked a revolution — and some controversy — in dental care during the 20th Century.
After decades of research and testing, most dentists now agree that fluoride reduces decay by interfering with the disease process. The optimum pH level for the mouth is neutral; however, this environment constantly changes as we eat, especially if we ingest foods or beverages high in acidity. A high acid level softens tooth enamel (a process called de-mineralization) and can lead to erosion if not neutralized. In addition, a thin layer of bacteria-rich plaque called biofilm that adheres to tooth surfaces is also acidic and is the cause of tooth decay, possibly more so in teeth made more susceptible from enamel erosion.
When fluoride is in “the right place” (present on the tooth surface and in our saliva, the body's natural acid neutralizer), it helps inhibit de-mineralization and aids in the re-hardening of the enamel (re-mineralization).
Although fluoride needs to come into direct contact with tooth enamel for optimum effectiveness, ingesting it can also prove beneficial. The fluoride we ingest eventually becomes deposited in bone. As bone grows and changes it releases this reserved fluoride back into the bloodstream where it eventually becomes part of saliva; the saliva brings it into contact with tooth surfaces.
The two most prominent ways we encounter fluoride are through fluoridated drinking water and in toothpaste. There continues to be concerns about what constitutes safe levels of fluoride in drinking water and over possible side effects like teeth staining and changes in bone structure. However, extensive studies have conclusively shown that even minimal levels of water fluoridation and the use of fluoride toothpaste have reduced tooth decay.
As the Colorado dentist discovered over a hundred years ago, fluoride is truly remarkable as a cavity fighter. Whether you have access to fluoridated water or not, we encourage you to use fluoride toothpaste to strengthen your teeth against decay.
