Fluoride in mouth after cleaning (bleeding mouth) can it cause an infection?

No: The presence of Fluoride in your mouth cannot cause an infection. Bacteria and other pathogens cause infections. I recommend you discuss your concerns with the dentist who actually treated you.

Definitely, no: Having professionally applied fluoride treatments after your dental cleaning and scaling, as well as using a fluoride rinse at home, not causing an infection and is also helpful to protecting your teeth from decay.

Nope: Topical fluoride does not contain pathogens. Discuss your concerns with your dentist.
