(Purchased with my own money) Interdental brush

It's an SSS 0.7mm L-shaped interdental brush...

I think interdental brushes or dental floss are essential for brushing every nook and cranny properly.

It's a bit of a hassle, but I make sure to use an interdental brush for my dental health.

The straight type was uncomfortable around my molars, so I think using the L-shaped one is more comfortable and better...
