Dental floss oral care

I practice oral care with dental floss every day after meals to protect my gums and prevent cavities. I have interdental brushes at home, but I don't know how to use them properly, so I only use dental floss. I eat twice a day, and I floss both times. Since I am getting older, food tends to get stuck easily, so I feel like I can't go without flossing. Brushing alone isn't enough to remove food particles, so I make sure to floss in addition. I've heard that if cavities form between teeth, treating them is difficult and expensive. Cavities on the chewing surfaces are immediately visible and treatable, but if they form between the teeth, the gaps need to be dug out to treat them, which is why I floss diligently. Also, flossing the tips of the molars is beneficial because the ends are often hard to clean. Flossing after meals is a must. I use Daiso floss; it's affordable, so using it every day isn't a burden. One pack lasts a long time. I recommend using cheap ones; tear off a long strip like I do.
