Colgate

I used a pencil and unfortunately no. Something whiter right after use but doesn't last long.

Very good brush for tight tooth gaps. Cleans really well.

I want to believe that it actually makes a difference, especially after 1-2 days of use, but the biggest problem I have with it is that it foams a lot after use, even though I rinse my mouth thoroughly. It takes a long time to get rid of it. Unfortunately, I won't be buying it again! 🧷
