So far so good. I have sensitive teeth. I really drink a lot of coffee. Smoking too. Yellow stains are firmly attached to the front teeth. It is difficult to remove. A lot of effort has been taken to remove this stain. But I could not get good results. I found this product with a friend's recommendation and it's been a week since I applied it. I saw my teeth become slightly white. It worked definitely. Looking forward to better results in the future. I will use it steadily.
It is a great product. This is one of the best whitening products I have used. I'm very picky about the products I use. Do not use any product. Suspicion and final determination of safety and operability. This product was selected in accordance with my selection process. This whitening product certainly works well and has no sensitivity at all. I have not experienced any side effects. Highly recommend!
I had tried other brands of whitening pens and liked them, but this brand was far better. The formula is much thicker than others and so adheres to teeth better and longer, where the other brands are so thin that the product rolls or wipes off when you close your mouth. It keeps my teeth white even though I do smoke and drink a lot of coffee.
It's a great product. Those who have used these teeth whitening pen will know how convenient it is. Really good. Unlike whitening strips, there is no sensitivity at all. It works really well. The gel doesn't really have severe heterogeneity after use. Fine. You can leave it at home. This teeth whitening pen is good to carry again. Easy to carry Highly recommend because it is a great product.
