My all-time favorite dental floss is Plackers Micro Mint! I bought it at Olive Young, and unlike regular floss, it has a handle, making it comfortable and preventing it from slipping. The thread is coated with a mint scent, so it feels refreshing, and it doesn't break easily. Plus, it comes with a portable toothpick under the handle, which is great for removing stubborn debris. Once you use this, you won't be able to go back to regular floss...
