| Anyone Had this Happen to them??? or know anything?
Ok, hi everyone! i whiten my teeth with over the counter products alot, and lately i have noticed a blue tint around the edges of my upper teeth. i read in a magizine that if this happens to stop whitning and it will go away and repair itself, but it doesnt seem to be working. is this a problem or is it just an individuality of every different person?
