Details The orthodontic nozzle and the ultrasonic nozzle enable easier, faster, thorough orthodontic appliance care, plaque removal and periodontal pocket care. The thorough cleaning of teeth, gums and braces requires a special tool other than a toothbrush, and takes time and effort and during orthodontic treatment, food debris and plaque easily accumulate between teeth and braces. If plaque remains on teeth and gums after brushing, it may cause tooth decay and gingivitis. An irrigator that washes away food debris with powerful water flow, plus a tuft brush that scrubs off plaque around orthodontic appliances. Oral care during orthodontic treatment, which was troublesome and difficult until now, is completed with this single unit. It's quick, easy and hygienic. Narrow gaps, such as those around brackets and between wires and teeth, were previously very hard to clean. The pointed bristles of the new nozzle's tuft brush reach these areas to thoroughly clean them. Narrower nozzle increases water jet speed and water vapor bubbles are generated in the ultrasonic nozzle. A full 600 mL water tank provides sufficient jet washing time (2 min. and 10 sec. of use when using the orthodontic nozzle.) Water pressure can be adjusted in 10 steps, and water flow strength the last time the unit was used is automatically memorized. Easy filling and maintenance, water tank is washable in a dishwasher. Convenient dual power cord outlet lets you pull out the cord from both the right and left.
