What are the three forms of fluoride approved by the FDA for use in toothpaste?
stannous fluoride, sodium fluoride and sodium monofluorophosphate
The three fluoride compounds approved for dental use in the United States are stannous fluoride (fluoride combined with elemental tin), sodium fluoride (fluoride and sodium), and sodium monofluorophosphate (a different compound of fluoride and sodium). Please don't try the others on your teeth!
hydrofluoric acid, fluorine and fluorochloro hydrocarbons
hydrogen fluoride, calcium fluoride and sulfur hexafluoride
Fluoride exists naturally in nearly all water sources. What fluoride level does the American Dental Association (ADA) recommend for drinking water?
less than .1 parts per million
between 1.2 and 2.7 parts per million
between .7 and 1.2 parts per million
According the ADA, the ideal fluoride level is .7 parts per million (ppm). Up to 1.2 ppm is considered acceptable, but more than that may put your children at risk for developing dental fluorosis. If your water contains more than 2 ppm of fluoride, the ADA recommends that you use bottled or treated water.
What should you do if your child occasionally swallows all of the toothpaste used to brush his or her teeth?
Don't panic! Although it's best to avoid overconsumption of fluoride, a mouthful of toothpaste here and there shouldn't cause too much damage.
As long as you're using no more than the recommended pea-sized amount, just continue to closely supervise brushing and keep reminding your child to spit. If he or she won't or can't spit, talk to your pediatrician about using less toothpaste or switching to a fluoride-free paste or plain water until the child is able to avoid swallowing.
Call the National Poison Control Center.
Stop brushing until your child is old enough to keep from swallowing, usually around age 6 or 7.
In addition to toothpaste and drinking water, fluoride is commonly found in which foods?
fruit juices, sodas, baked goods, meat products, snacks and baby foods
Fluoride occurs naturally in many foods such as meats and certain vegetables. Many fruit juices and sodas are high in fluoride, as they are made with fluoridated water. Even baked goods, snacks, baby foods and other processed foods may contain significant amounts of fluoride.
water, soil and rocks throughout the Earth's crust
Fluoride is a natural mineral found abundantly in water, soil and rocks throughout the Earth's crust. Fluoride is a chemical ion of the element fluorine, meaning simply that it has one extra electron that gives it a negative charge.
How does the fluoride in toothpaste help to prevent tooth decay and cavities?
by protecting teeth from acid and repairing areas that are already damaged by acids
Topical fluoride prevents bacteria from forming acids that erode the tooth enamel and cause decay. And in areas of the teeth that have already been damaged by acids, fluoride builds up in the weakened areas and begins to strengthen, or remineralize, the teeth.
by forming a water-resistant seal around the teeth
by engaging in loud and heated battles against the invading "cavity creeps"
True or False: Breastfeeding mothers should take fluoride supplements to ensure that their infants receive adequate fluoride.
Infants do not need to have their breast milk supplemented with fluoride. In fact, there is some debate even among health professionals as to whether it's OK to mix infant formula with fluoridated water.
When should children make their first visit to the dentist?
The American Academy of Pediatrics recommends that children visit the dentist sometime around their third birthdays; possibly earlier if the child shows signs of dental problems such as staining or tooth decay.
People are at risk of developing dental fluorosis until what age?
Dental fluorosis is a concern for children 8 years and younger, since this is when permanent teeth are developing under the gums. Once the teeth have developed and broken through the gums, they can no longer develop fluorosis.
What is the recommended daily fluoride intake for children?
.05 milligrams per kilogram of body weight
While the recommended daily fluoride intake for adult women and men is 3 mg and 4 mg, respectively, the recommended intake for children is calculated by multiplying .05 times the child's weight in kilograms. So a 20 kg (40 pound) child would need about 1 mg of fluoride per day.
