Fluoride is the most effective agent available to help prevent tooth decay. It is a mineral that is naturally present in varying amounts in almost all foods and water supplies. The benefits of fluoride have been well known for over 50 years and are supported by many health and professional organizations.
Fluoride works in two ways:
Topical fluoride strengthens the teeth once they have erupted by seeping into the outer surface of the tooth enamel, making the teeth more resistant to decay. We gain topical fluoride by using fluoride containing dental products such as toothpaste, mouth rinses, and gels. Dentists and dental hygienists generally recommend that children have a professional application of fluoride twice a year during dental check-ups.
Systemic fluoride strengthens the teeth that have erupted as well as those that are developing under the gums. We gain systemic fluoride from most foods and our community water supplies. It is also available as a supplement in drop or gel form and can be prescribed by your dentist or physician. Generally, fluoride drops are recommended for infants, and tablets are best suited for children up through the teen years. It is very important to monitor the amounts of fluoride a child ingests. If too much fluoride is consumed while the teeth are developing, a condition called fluorosis (white spots on the teeth) may result.
Although most people receive fluoride from food and water, sometimes it is not enough to help prevent decay. Your dentist or dental hygienist may recommend the use of home and/or professional fluoride treatments for the following reasons:
- Deep pits and fissures on the chewing surfaces of teeth.
- Exposed and sensitive root surfaces.
- Fair to poor oral hygiene habits.
- Frequent sugar and carbohydrate intake.
- Inadequate exposure to fluorides.
- Inadequate saliva flow due to medical conditions, medical treatments or medications.
- Recent history of dental decay.
Remember, fluoride alone will not prevent tooth decay! It is important to brush at least twice a day, floss regularly, eat balanced meals, reduce sugary snacks, and visit your dentist on a regular basis.
Frequently Asked Questions About Fluoride
What are dental fluoride treatments and how do they benefit children's teeth?
Is fluoride treatment safe for my child?
How often should my child receive professional fluoride treatments?
What should we expect during and after a fluoride treatment?
Fluoride treatments at ABC Children’s Dentistry are quick, simple, and painless. The treatment typically follows your child’s regular dental cleaning and examination. The fluoride comes in several child-friendly forms, including flavored foams, gels, or varnishes that Dr. Singer or our hygienist will apply directly to your child’s teeth using a small brush or tray. The entire application process takes just a few minutes. After application, your child will need to avoid eating or drinking for about 30 minutes (for foams/gels) or up to 4-6 hours (for varnishes) to allow the fluoride to fully absorb into the tooth enamel. For varnish applications, your child’s teeth may appear slightly yellow or dull until the varnish is brushed off the next day – this is completely normal. Your child can return to their normal activities immediately following the treatment. We’ll provide specific post-treatment instructions based on the type of fluoride used to ensure maximum benefits.
Are there alternatives to fluoride treatments for cavity prevention?
Yes, there are several complementary approaches to cavity prevention that work alongside or as alternatives to fluoride treatments. Dental sealants are clear protective coatings applied to the chewing surfaces of back teeth to prevent food and bacteria from getting trapped in the deep grooves. They can reduce cavity risk by up to 80% in molars and are completely fluoride-free. Proper oral hygiene at home remains essential – using appropriate toothpaste, brushing twice daily, and flossing regularly. A balanced diet low in sugary foods and drinks is equally important for preventing cavities. At ABC Children’s Dentistry, Dr. Singer takes a comprehensive approach to cavity prevention, working with each family to develop a personalized plan that may include various preventive strategies based on your child’s specific needs and your family’s preferences. We respect that families have different perspectives on dental care options and are happy to discuss all available approaches to keeping your child’s smile healthy.
