You will see a more even colour between the white spots and your teeth. Those spots could have been caused by fluorosis (fluoride staining), decalcification (breakdown of the teeth, on the verge of a cavity) or some sort of trauma to your teeth as a child (a fever or a blow to the mouth). Please be aware there is also a chance that the white spots on the teeth may become even whiter if you have any concerns please visit your dentist.
