Recently a parent voiced a concern over the fluoride used by her son's dentist that may be contraindicated for him due to his peanut and tree nut allergy. I believe she obtained this information on the internet and not directly from her dentist. Is there any cause for concern at all? Thank you for your time.


Thank you for your inquiry.

I know of no scientifically validated effect of fluoride on food allergy of any sort, including peanut and tree nut allergy. Also, I could not find any reference to such in a search of the medical literature.

Thank you again for your inquiry.
