The bottles in mine are dry rotten so to speak. When I tried to squeeze the gel out, all the sides separated and the gel spilled out. However, I didn't notice any difference on my teeth at all, I sent it back and ordered it from the actual manufacturer of the product (same price) and noticed a big difference in the color of my teeth. I think the bottles were very old and expired. Something was definitely wrong. I'm just sharing my experience.
