I've always struggled with bleeding gums, and my dentist kept telling me I needed to floss more consistently. Honestly, I hated traditional floss - it hurt my fingers, took forever, and I'd only do it maybe once a week if I remembered. I was skeptical about this water flosser at first, but after using it for three weeks, my gums have completely stopped bleeding. My last dental cleaning, the hygienist actually commented on how much healthier my gums looked. The water pressure settings are perfect - I started on the lowest setting and worked my way up as my gums got used to it. Now I actually look forward to flossing because it feels refreshing, almost like a mini mouth massage. The tank holds enough water for a full floss session, and it's so much faster than string floss. I'm using it twice a day now, which I never would've done with regular floss. The only minor downside is that it can get a bit messy if you don't keep your mouth closed over the sink, but you get the hang of it quickly. Totally worth the investment for better oral health.
