I feel refreshed.

My husband asked me to buy it, so I did, and I was surprised too when I first used it.

I thought I was brushing my teeth hard, but after licking them for about 30 seconds, I saw food particles coming out.

At first, you can do it once a day, and then once or twice a week.

It doesn't come out like the first time. Instead, my teeth get sensitive if I use it often.
