Well, I'm no expert but U can try baking soda and hydrogen peroxide... mix them up and then swish in your mouth. but dont do it 2 often, because those are both very acidic! Hope I helped
I would say its C because peer pressure <span>results from someone who tries to convince you to do something you normally wouldn't do. idk if im right tho pls tell me if im wrong!
-hope this helps :3</span>
