Fluoride is found in nature in soil, plants, and water. Brushing with fluoride and having a health professional apply fluoride varnish to the teeth are important ways to make teeth strong and prevent tooth decay.
Fluoride Toothpaste
- Brush your child’s teeth after breakfast and before bed once the first tooth begins to show.
- Use a child-sized toothbrush with soft bristles and fluoride toothpaste.
- See Healthy Habits for Happy Smiles: Brushing Your Child’s Teeth for more information.
Fluoride Varnish
- Fluoride varnish is painted on a child’s teeth to prevent or reduce cavities.
- It is not permanent but keeps fluoride on the teeth for several hours.
- Fluoride varnish has a pleasant taste and is well tolerated by children.
