또또오늘뭐하지
수압조절된다고하니좋으네요
I bought this after being recommended for care following my dental implants. It's a Waterpik product, and I purchased it at Costco. The water pressure is adjustable, but if I set it to 10, my gums sometimes bleed.
Even after brushing my teeth, quite a bit of debris comes out with a Waterpik. I am especially surprised on days when I eat spicy food or meat.
