An irrigator – a device to clean teeth and gums with water.
The water jet massages gums and removes all the dirt between teeth, which is beyond reach of toothbrush and toothpicks. On the other hand, irrigator doesn’t damage teeth or gums, like tooth cleansing floss do.
Irrigators are also available as separate devices, which take water from a build-in tank and use an electrical pump to generate water jet. But they are too bulky for a tiny bathroom and the water pressure is minimal compared to that of running water. So choose pass through
irrigators. They are available as sink faucet clamp-on and shower pass through.
