Clean teeth and a fresh breath contribute a lot to your general well-being. Unfortunately, brushing your teeth twice a day is not enough to achieve this. Many harmful bacteria are located deep in the interdental spaces, at exposed tooth necks, and in hard-to-reach places. Therefore, dentists recommend the daily use of dental floss in addition to the toothbrush. A useful alternative to this is the water flosser. It rinses away food residues and deposits in the interdental spaces with a water jet. It also freshens breath and - equipped with a massage function - can even strengthen the gums.

The following mouth shower comparison describes a selection of popular models in detail and looks at their features and functions.

What to look for when buying a water flosser?

When selecting a specific model, it is helpful to go through a checklist. Anyone who wants to buy a water flosser should pay particular attention to the following:

  1. Pressure system. Some models have only one tank, others work with a water-oxygen mixture.
  2. Power supply. Either there is a power cord to plug into a wall outlet or operation is by batteries/rechargeable in-build power source.
  3. Water tank. The larger its capacity, the less often water needs to be refilled. Large tanks are especially useful for families.
  4. Water pressure. Devices with a low pressure are less effective. It is best to choose a water flosser with adjustable levels. Thus, the pressure can be regulated individually.
  5. Ease of use. Is the water flosser easy to use, and can the water be easily refilled? Portable water flossers should be as light as possible.
  6. Additional functions. Some models have features like an integrated gum massage or 360-degree turning nozzles.

Since the water flosser comes into contact with food debris, bacteria, and germs on a daily basis, regular cleaning is essential. If this is neglected, the bacteria can multiply, settle in and on the device and enter your body during the next use.
