You're telling me trident helps fight cavities, it always has? I knew trident didn't cause cavities, but help fight them? No, I didn't know that. It's hard to believe a little piece of gum can do all that. It's true. New dental studies prove it. Chewing trident after sugary snacks reduces acids that form on teeth. It's these acids that can cause cavities. Ask your dentist. Something that's delicious and good for you, I love it. Couldn't happen to a better gum. Trident, good to chew and fights cavities too.
