Fluoride Gel

About fluoride gel

Professionally applied fluoride comes as a gel, a foam or a rinse and is applied by a dental professional during the visit. Because an early study reported higher enamel uptake in an acidic environment, fluoride gel is often formulated to be highly acidic, at about pH 3.

A viscous gel, generally applied in the office for 1 to 4 minutes. Products sold in the United States include acidulated phosphate fluoride gel at 1.23 percent fluoride and sodium fluoride gels and foams at 0.9 percent.
