I usually use the floss to clean and find that the gap between my teeth is getting bigger and bigger, and I can't clean my teeth perfectly. This flosser is full of power to deeply clean the mouth and teeth 😁 The water tank is very big .and the power is for 30 days. It can be used perfectly whether you are in the office, at home, or when you travel! #floss #oralhealth #waterflosser #cleanteeth #oralhygiene #cleanteeth #foreveryone
