I buy interdental brushes in bulk and use them.

I learned this while visiting the dentist: many interdental brushes are made in China.

It is said that Chinese-made interdental brushes sold domestically are swarming with E. coli.

So, I ended up buying a domestic product after getting a recommendation from the dentist.

Since it's endorsed by the dental clinic, it seemed stable and felt good to use.

It removes foreign objects well and cleans the spaces between the teeth effectively. It's great.
