The U.S. Food and Drug Administration has moved to take prescription ingestible fluoride supplements, the drops and tablets swallowed by young children, off the market. In an action dated October 31, 2025, the FDA notified companies that these products were never FDA approved and advised that they should not be given to children under age 3 or to any child at low to moderate risk of tooth decay. Topical fluoride that stays on the teeth, such as fluoride toothpaste and in-office varnish, is not affected, and the American Dental Association still backs prescription fluoride for high-risk children in areas with little fluoride in the water.
If your family has ever filled a prescription for fluoride drops or chewable tablets, this change matters for your next visit. Here is what happened, what the evidence says, and the exact questions to raise with your dentist as summer checkups and back to school appointments fill up.
What did the FDA actually change about kids' fluoride supplements?
The FDA notified four companies that it intends to pursue enforcement action against unapproved ingestible fluoride drug products labeled for children, rather than issuing an outright nationwide ban. According to the agency's October 31, 2025 announcement, these concentrated fluoride drops and tablets are swallowed by infants and toddlers and had never gone through FDA approval. The agency paired the notices with a letter to healthcare professionals and said it is opening a fluoride research agenda with the National Institutes of Health and the U.S. Department of Health and Human Services.
- The FDA sent enforcement notices to 4 companies marketing unapproved ingestible fluoride drug products for children (U.S. Food and Drug Administration, October 31, 2025).
- The guidance says ingestible fluoride supplements should not be given to children under age 3, or to any child at low to moderate risk of tooth decay (U.S. Food and Drug Administration, 2025).
- The ADA still supports prescription fluoride for higher-risk children whose drinking water contains less than 0.3 parts per million of fluoride, dosed at 0.25 to 1.0 mg per day by age (American Dental Association, 2025).
Does this mean fluoride is unsafe for my child?
No, and it is important to separate the products from the mineral. The FDA action targets only swallowed prescription supplements, not the fluoride in toothpaste, professionally applied varnish, or community drinking water. FDA Commissioner Marty Makary framed the concern as one of caution, saying "there are better ways to protect children's teeth than taking unapproved ingestible fluoride, which is now recognized to alter the gut microbiome." Decades of research continue to support topical fluoride and community water fluoridation as safe, effective ways to reduce cavities, which is why the ADA drew a sharp line between systemic supplements and everyday topical use.
For a broader look at how fluoride policy is shifting at the local level, see our earlier report on Louisiana's new fluoride vote law, Act 731, which lets individual communities decide whether to keep fluoride in their tap water.
Which children were most likely to be prescribed these supplements?
Prescription fluoride supplements were aimed at a narrow group: children living where the tap water carries very little fluoride and who also face a high risk of decay. In fluoridated communities, most children already get protective fluoride from the water and from toothpaste, so supplements were rarely needed. The children affected by this change are largely those on private wells or on public systems that do not fluoridate, whose dentists had used drops or tablets to fill the gap. That is exactly where families now need a clear conversation about alternatives.
Fluoride options for children, and which the FDA action touches
| Method | How it works | Best for | Affected by the FDA action? |
|---|---|---|---|
| Prescription fluoride drops or tablets | Swallowed daily, works through the body (systemic) | High-risk children in low-fluoride areas | Yes, targeted for removal |
| Fluoride toothpaste | Applied to teeth twice daily, then spit out (topical) | Nearly all children old enough to brush | No |
| In-office fluoride varnish | Painted on teeth at a dental visit (topical) | Children at any decay risk, every 3 to 6 months | No |
| Community water fluoridation | Low level of fluoride in public tap water | Entire community, all ages | No |
What did the ADA say in response?
The ADA pushed back on the method while agreeing supplements are not for everyone, arguing that a prescriber's judgment should guide care rather than a blanket label change. In its October 31, 2025 statement, the association reaffirmed that it supports dietary fluoride supplements for children at high risk of decay whose water is fluoride deficient, following its long-standing schedule of 0.25 mg per day for ages 6 months to 3 years, 0.50 mg per day for ages 3 to 6, and 1.0 mg per day for ages 6 to 16 when water fluoride is below 0.3 parts per million.
"A doctor's clinical judgment, not a new warning label, should remain the guiding factor in determining appropriate fluoride use for children." Dr. Richard J. Rosato, ADA President, October 31, 2025
What should I ask my dentist at a back to school visit?
Start by confirming whether your child even needs a supplement, then ask what replaces it if they do. Bring any current prescription to the appointment and work through a short checklist with your dentist or pediatric specialist. A practice that knows your child's history can weigh their decay risk, your water source, and their brushing habits before deciding.
- Is my child considered high risk for cavities, and what is our home tap water's fluoride level?
- If we were using drops or tablets, should we switch to fluoride varnish, a prescription-strength toothpaste, or sealants?
- How often should my child get in-office fluoride varnish this year?
- Are there sugar or snacking habits we should change to lower decay risk without supplements?
Families searching for a practice that handles these conversations can browse verified pediatric offices on Smile Listing, such as Kensington Pediatric Dentistry and Orthodontics in San Diego or Hurst Pediatric Dentistry in Texas. Pairing the change with a routine back to school dental checkup is a practical way to reset your child's prevention plan for the year.
Frequently asked questions
Are fluoride drops and tablets banned now?
Not with a single nationwide ban. The FDA sent enforcement notices to four companies and advised against giving ingestible fluoride supplements to children under age 3 or to low to moderate risk children, which is expected to remove most of these products from the market over time. Ask your pharmacy and dentist about the current status of any specific prescription.
Should I stop my child's fluoride toothpaste?
No. The FDA action does not touch topical fluoride. Fluoride toothpaste, used in the amount your dentist recommends for your child's age and spit out rather than swallowed, remains a core, well-supported way to prevent cavities.
My town's water is not fluoridated. How do I protect my child now?
Ask your dentist about in-office fluoride varnish every three to six months, prescription-strength fluoride toothpaste, and dental sealants on the back teeth. Combined with twice-daily brushing and limits on sugary drinks, these steps replace much of what a daily supplement was meant to do.
At what age should my child first see a dentist?
The American Academy of Pediatric Dentistry recommends a first dental visit by the child's first birthday or within six months of the first tooth appearing, then a checkup every six months. Early, regular visits let a dentist tailor fluoride and prevention to your child before problems start.
