The first time you use your Fever Smile PRO kit, you’ll mould the mouth trays to ensure they perfectly fit your unique mouth shape.
Then, fill the mouth trays with a thin thin layer of our whitening gel, gently insert it into your mouth and press it against your teeth, and activate the LED light.
Our active ingredient breaks apart the chemical bonds in organic surface stains and inorganic stains found inside of your tooth.
The structure of your tooth isn't affected in any way; the result is simply beautiful, sparkling teeth you’ll love to show off!
