Use supervised fluoride toothpaste and professional preventive varnish; assess total exposure before supplements.
- Home: grain-of-rice-sized toothpaste twice daily.
- Professional: under six, unit-dose 5% sodium fluoride varnish contains 2.26% fluoride ion.
- Frequency: the policy gives no fixed interval, but the companion high-risk pathway for ages 0–5 lists three-month recall and professional topical fluoride. Use that plan for this high-risk child and reassess risk/response. The fluoride best practice gives at least six-monthly professional treatment for children at caries risk.
- Lesion arrest: SDF is a separate decision with its own selection and staining consent.
