I would say it works better than the crest whitening toothpaste. My mom has used it and has received compliments to her white smile at the dentist. While using it I have noticed an increase in brightness.
I really like using it! It was my first time using aerosol and I really enjoyed it. Sometimes it’s hard to know if I put too much or if I need more. I like using it Bc I don’t have to worry if marks will appear on my clothes . However make sure you let it dry before wearing a shirt that rubs against pit
