This gel. Slightly bleaches, probably on 1 tone. I have the nature of a yellowish enamel, so I did not expect a miracle. Lathers bad, but good clean - smooth teeth until the evening. And when it is clean for the night, get up in the morning with a pleasant feeling of cleanliness in the mouth. Well polished, straight teeth gleaming. Brush your teeth at least 3 minutes (or even 5 min.!). This advice is know from childhood, but the lazy, but do not be lazy, the result is completely different! Once try this pasta - very good.
