I had zoom whitening 4 days ago, on day 3.5 I had a half of a glass of white wine (having a yellow tint.) I've had nothing but white bagels, baked potato and white cream cheese for 4 days aside from this yellowish wine. I brushed one hour after the wine, but in the morning I notice a yellow tint around my teeth near gumline. Is this permanent? Did I ruin the effects of my teeth whitening or does this happen several days after regardless of food/drink?:(
