Fluoride
More than 70 years of scientific research has consistently shown that an optimal level of fluoride in community water is safe and effective in preventing tooth decay by at least 25% in both children and adults.
Fluoride benefits both children and adults.
Before teeth break through the gums, the fluoride taken in from foods, beverages, and dietary supplements makes tooth enamel (the hard surface of the tooth) stronger, making it easier to resist tooth decay. This provides what is called a “systemic” benefit.
After teeth erupt, fluoride helps rebuild (remineralize) weakened tooth enamel and reverses early signs of tooth decay. When you brush your teeth with fluoride toothpaste, or use other fluoride dental products, the fluoride is applied to the surface of your teeth. This provides what is called a “topical” benefit.
In addition, the fluoride you take in from foods and beverages continues to provide a topical benefit because it becomes part of your saliva, constantly bathing the teeth with tiny amounts of fluoride that help rebuild weakened tooth enamel.
Indications that fluoride might be needed:
- poor oral hygiene
- active caries
- eating disorders
- drug or alcohol abuse
- lack of regular professional dental care
- active orthodontic treatment
- poor oral hygiene
- high levels of caries-causing bacteria in the mouth
Type
- By tray
- Fluoride varnish
- Mouthwash
- Fluoride tablet
Pro
- Remineralize weakened tooth surface against caries forming
Cons
- Possible nausea or vomiting for over fluoridation
- Create fluorosis or white spot on tooth surface in over fluoridation
