TERRIBLE PLAN
If I soak my teeth with bleach, will I get stains in my mouth?
No stains, but yes to chemical burns and ruined teeth—don't bleach your mouth unless you hate yourself.
Soaking your teeth in bleach won't give you cute stains; it'll cook your gums and teeth like a toxic chemistry experiment gone wrong. Bleach is a harsh chemical intended for surfaces, not your mouth. Using it on your teeth leads to serious burns, enamel damage, and possibly permanent tooth loss. In other words, take that bleach bottle away before you do something you'll regret forever.
Do not use bleach or any harsh chemicals in your mouth. If accidental exposure occurs, rinse thoroughly and seek medical advice immediately.
