I bought this with my own money and highly recommend Oral-B Glide ProHealth dental floss.

My gums are weak, so if I don't buy the right floss, they sometimes bleed. That is why I am usually very interested in dental floss products.

Oral-B Glide ProHealth dental floss

I really like it because I haven't experienced any bleeding while using it and it removes food particles effectively. Also, the mint flavor isn't spicy and has just the right amount of freshness. The only downside is that it is a bit expensive, but since one purchase lasts a very long time, I am satisfied.
