Using Fluoride to Protect your Child’s Teeth

What is fluoride?

Fluoride is a compound that contains fluorine, a natural element. Using small amounts of fluoride on a routine basis can help prevent tooth decay. In areas where fluoride does not occur naturally, it may be added to community water supplies. Research shows that community water fluoridation has lowered decay rates by over 50 percent, which means that fewer children grow up with cavities.  In the greater Wenatchee area our water is not fluoridated.  Our children rely on prescriptions from their dentist or doctor for optimal fluoride amounts.  Many of our surrounding areas have some naturally occurring fluoride in the water.  For those areas Dr Cara may recommend that you have your water tested so that she may prescribe the accurate amount of supplementation for your child.  

How does fluoride prevent cavities?

Fluoride inhibits loss of minerals from tooth enamel and encourages remineralization (strengthening areas that are weakened and beginning to develop cavities). Fluoride also affects bacteria that cause cavities, discouraging acid attacks that break down the tooth. Risk for decay is reduced even more when fluoride is combined with a healthy diet and good oral hygiene.

Will my child need fluoride supplements?

Dr Cara considers many factors before recommending a fluoride supplement. Your child’s age, risk of developing dental decay and dietary sources of fluoride are important considerations. Infant formulas contain different amounts of fluoride. Bottled, filtered and well waters also vary in the amount of fluoride they contain. The educated team at Children’s Dentistry can help determine if your child is receiving -- and not exceeding -- the recommended amount.

How safe is fluoride?

Using fluoride for the prevention and control of decay is proven to be both safe and effective. Nevertheless, products containing fluoride should be stored out of the reach of young children. Too much fluoride could cause fluorosis of developing permanent teeth. Fluorosis usually is mild, with tiny white specks or streaks that often are unnoticeable. In severe cases of fluorosis, the enamel may be pitted with brown discoloration. Development of fluorosis depends on the amount, duration and timing of excessive fluoride intake. The appearance of teeth affected by fluorosis can be greatly improved by a variety of treatments in esthetic dentistry.

What type of toothpaste should my child use?

Your child should use toothpaste with fluoride and the American Dental Association Seal of Acceptance. Brushing twice a day (after breakfast and before bedtime) provides greater benefits than brushing once daily. Parents should dispense toothpaste to prevent their young children from swallowing too much.

How much toothpaste should my child use?

For children under 2-years-old, use a smear of fluoridated toothpaste. For those aged 2 to 5 years, a pea-sized amount is recommended. Children should spit out and not swallow excess toothpaste after brushing.

What is topical fluoride?

Topical fluoride is a preventive agent applied to tooth enamel. It comes in a number of different forms. At Children’s Dentistry we utilize gel, foam and varnish, depending on the needs of your child.  Fluoride varnish is brushed or "painted" on the enamel. Varnish is especially useful for young patients and those with special needs who may not tolerate fluoride trays. Children who benefit the most from fluoride are those at moderate to high risk for decay. Risk factors include a history of previous cavities, a diet high in sugar or carbohydrates, orthodontic appliances, and certain medical conditions such as dry mouth.
