Decakila's cleaning set uses water pressure to clean teeth, even in the most difficult areas. Using a water flosser makes it easier for people who have braces or a bridge, as it can effectively remove food debris that traditional dental floss does not serve in these cases. You can use it with mouthwash to more effectively combat plaque between teeth and bacteria.
