Great for crowns
Most of my teeth are crowns or implants. They stay pretty white because they are crowns. However, they get stained a bit with the same things that stain regular teeth.
After I got my teeth cleaned I started using SuperSmile toothpaste every morning. My crowns have maintained the same white as they get them when you have your teeth cleaned.
I love this product. Well worth the expense. Which isn’t very much for what you get.
Highly recommended for anyone that has Crowns, veneers.
