Perio Dental Cooling Spray

It is useful in situations where it is difficult to brush your teeth.

It is small and easy to carry, and immediately relieves the dryness in the mouth.
The scent is reduced and refreshing, but it doesn't last very long.

The freshness doesn't last long, but it's better than nothing...

I initially bought it at Daiso, but online
If you purchase, you can buy them in a bundle for a slightly cheaper price.

I think I use about one every one or two months.
