Walmart and most drug stores have a whitening gel kit that’s under $10 called PlusWhite 5 Minute Gel and I swear by it. I’ve used white strips and this stuff worked way better and faster in my experience.

Sharp canines are cool imo. I have “fangs” too and I think they look hot on me lol

Most important thing is brushing twice a day, flossing, and scraping your tongue. Bad breath and junk in between your teeth is way worse than yellowing or crooked teeth.
