In the last half century, fluoride has become an effective weapon against tooth decay. The naturally occurring mineral helps strengthen enamel, the teeth's hard, protective cover.
Although it's safe for consumption overall, too much during early tooth development can lead to fluorosis, a brownish, mottled staining in enamel. To avoid it, a child's daily consumption of fluoride should optimally be kept at around 0.05-0.07 milligrams per kilogram of body weight, or an amount equal to one-tenth of a grain of salt per two pounds of weight.
The two main therapeutic fluoride sources have limits to help maintain this balance: utilities that fluoridate drinking water are required to add no more than 4 parts fluoride per million (ppm) of water; toothpaste manufacturers likewise only add a small amount of fluoride compared to clinical gels and pastes dentists apply to teeth for added decay protection.
But drinking water and toothpaste aren't the only sources of fluoride your child may encounter. Even if you have a non-fluoridated water supply, you should still keep a close watch on the following items that could contain fluoride, and discuss with us if you should take any action in regard to them.
Infant formula. The powdered form especially if mixed with fluoridated water can result in fluoride concentrations 100 to 200 times higher than breast or cow's milk. If there's a concern, use fluoride-free distilled or bottled spring water to mix formula.
Beverages. Many manufacturers use fluoridated water preparing a number of packaged beverages including sodas (two-thirds of those manufactured exceed .6 ppm), soft drinks and reconstituted fruit juices. You may need to limit your family's consumption of these kinds of beverages.
Certain foods. Processed foods like cereals, soups or containing fish or mechanically separated chicken can have high fluoride concentrations, especially if fluoridated water was used in their processing. When combined with other fluoride sources, their consumption could put children at higher risk for fluorosis.
Toothpaste. Although mentioned previously as a moderate fluoride source, you should still pay attention to how much your child uses. It doesn't take much: in fact, a full brush of toothpaste is too much, even for an adult. For an infant, you only need a smear on the end of the brush; as they grow older you can increase it but to no more than a pea-sized amount.

In 2016, voters in three states—California, Massachusetts and Nevada—joined Alaska, Colorado, Oregon, Washington and the District of Columbia in legalizing the use of recreational marijuana. These referenda moved the country closer to what may soon be a monumental political showdown between the states and the federal government, which still categorizes marijuana as a controlled substance.
But there’s another angle to this story often overshadowed by the political jousting: is increased marijuana use a good thing for your health and overall physical well-being?
When it comes to your dental health, the answer might be no. The Journal of Periodontology recently published a study that included frequent marijuana users showing increased signs of periodontal (gum) disease. This harmful bacterial infection triggered by plaque buildup can cause weakening of gum attachment to teeth and create the formation of large voids between teeth and gums called periodontal pockets. Left untreated, the disease can also cause supporting bone loss and eventually tooth loss.
The study looked at the dental treatment data of over 1,900 adults of which around one-quarter used marijuana once a month for at least a year. Marijuana users in the study on average had 24.5% of pocket sites around their teeth with depths of at least eight millimeters (an indication of advanced gum disease). In contrast, non-users averaged around 18.9% sites.
To be sure, there are several risk factors for gum disease like genetics, oral hygiene (or lack thereof), structural problems like poor tooth position or even systemic conditions elsewhere in the body. This published study only poses the possibility that marijuana use could be a risk factor for gum disease that should be taken seriously. It’s worth asking the question of whether using marijuana may not be good for your teeth and gums.
You brush and floss every day to rid your teeth and gums of disease-causing plaque. But while “showing up” is most of the battle, the effectiveness of your technique will win the war.
So, how good are you at removing plaque? One quick way to find out is the “tongue test”—simply rub your tongue along your teeth: they should feel smooth and “squeaky” clean. Surfaces that feel rough and gritty probably still contain plaque.
For a more thorough evaluation, your dental hygienist may use a product during your regular dental visit called a plaque disclosing agent. It’s a solution applied to your teeth that dyes any bacterial plaque present on tooth surfaces a certain color while leaving clean surfaces un-dyed. The disclosing agent shows you where you’re effectively removing plaque and where you’re not.
These products aren’t exclusive to the dental office—you can use something similar at home if you’d like to know how well you’re doing with your hygiene before your next visit. You can find them over-the-counter as tablets, swabs or solutions. You may even find some that have two dye colors, one that reveals older plaque deposits and the other newer plaque.
You simply follow the product’s directions by first brushing and flossing as usual, then chewing the tablet, daubing the swab on all tooth and gum surfaces, or swishing the solution in your mouth like mouthwash for about 30 seconds before spitting it out. You can then use a mirror to observe any dye staining. Pay attention to patterns: for example, dyed plaque scalloping along the gum line means you’ll need to work your brush a little more in those areas.
The dye could color your gums, lips and tongue as well as your teeth, but it only lasts a few hours. And while plaque disclosing agents are FDA-approved for oral use, you should still check the ingredients for any to which you may be allergic.
All in all, a plaque disclosing agent is a good way to occasionally check the effectiveness of your plaque removal efforts. By improving your technique you may further lower your risk of dental disease.
