Of course, well-known brands such as Colgate, Crest, and Black are good. I personally prefer domestic products, but products like toothpaste are a bit disappointing. I used to use domestic products, but I always have bleeding gums when brushing my teeth. Since I started using Colgate, there has been no bleeding. I have been using it till now. Of course, you have to use better ones. There are also many fakes on the market, so be careful. I bought a fake.
