I am a 24 year old male. I want to know what happens if you use whitening toothpaste with braces?
Nothing bad... it will not whiten the portion of teeth under the brackets so you will need to bleach or use the toothpaste later once the brackets are off
The enamel around the brackets whitens.
The area with the brackets will not whiten.
The only possible effect would be lightening of only the enamel around the exposed area and not that which is under the braces.
It can actually be beneficial. It can help you to avoid staining around your brackets. Which is what happens when you don't take care of your teeth while in braces. Once you get your braces removed you want to avoid the color of the tooth surface underneath the brackets from being noticeably different that the surrounding tooth's color.
Nothing. You can use any tooth paste.
