Q: Case Study 1
One of your patients is quite concerned about her toddler's dental health. She does not want him to have any cavities and plans to take every precaution possible. They live in an area that is not fluoridated. She felt proud that she filled the fluoride supplement prescription your dentist gave her 6 months ago and has the child take it every day after dinner. She was sure to point out that her child eats a well-balanced diet and they drink milk at every meal to help their bones and teeth form.

- They live in an area with no community fluoridation so it should not matter
- Fluoride supplements are needed but should be taken 30 minutes prior to or after ingesting breast milk, as its absorption can be reduced by the milk
A: Fluoride supplements are needed but should be taken 30 minutes prior to or after ingesting breast milk, as its absorption can be reduced by the milk
