Make sure to use an interdental brush.

I heard that using dental floss and interdental brushes is good. As I get older, grooves form between my gums and teeth, and food gets stuck in them that are hard to remove, which is uncomfortable. Should I say my gums are becoming more exposed? So, after brushing, I make sure to thoroughly scrub between them with an interdental brush. It removes the trapped food well and leaves my mouth feeling refreshed. It won't make the gaps widen further, right? Since the dentist recommended it, I think it's good to use it. Daiso has a wide variety of types. You should just buy the size that fits your teeth.
