One thought on “What causes the white streaks in the teeth after whitening?

    Yellow or brown teeth, surface stains, and uniformly darkened teeth are easiest to whiten. The results depend greatly on how discolored the teeth were originally. The amount of whitening varies from client to client and cannot be predicted or guaranteed; but in general use, teeth may lighten anywhere from 6 to 12 shades on the whitening shade guide.
