About waterBEST

Tooth decay affects many local young children, and most tap water in Lenoir County does not have fluoride.  The waterBEST study will help us find out if fluoride in bottled water can prevent tooth decay.

Lenoir county infants ages 2-6 months and their parents/guardians/caregivers can take place.


Frequently Asked Questions

What happens in this study?

Every month the study team will call to see if you need a delivery of 5-gallon water bottles, and a study team member will make a delivery if needed.  Families are asked to give their child the study water provided by the study team (not tap water).  Children should continue their usual diet and health care.


Every 3 months, parents will be interviewed about their child’s health.  Once a year, your child will have a dental check at home.

When your child turns 4-years old, they will have a dental exam at home.

Participants will be enrolled from April 2022 through April 2023.  Study visits will occur through 2026.
