Totally relate to the charcoal toothpaste messβit's like a mini crime scene every morning, haha. Keeping a cloth handy is actually pretty smart; might have to steal that idea myself. As for oil pulling, I've heard mixed things from patients too. Some swear by it, others don't notice much difference beyond freshness. Personally, I think the whitening effect might be more psychological or subtle at best.
You're spot-on about baking soda moderation though. It's effective, but too much can wear down enamel over time, and that's definitely not worth the risk. Honestly, quick fixes are tempting, but consistent habits like limiting staining foods (coffee, tea, wine...sadly) and regular brushing with fluoride toothpaste usually make the biggest difference long-term. Maybe boring advice, but it works. Either way, sounds like you're already doing a great job experimenting and finding what works for you. Keep it up!
