In a few words:
A device that complements oral hygiene, but in no way replaces flossing and proper brushing. Definitely an auxiliary device and not absolutely necessary.
+ Helps clean interdental spaces.
- Lacks the necessary intensity.
- Requires refilling with water until all teeth are finished.
- I would like it to have a 50cm longer power cord.
In more detail:
I had used the older Waterjet model and in this new model, I find it to have much less power. Even at setting 5, the water intensity is low. Perhaps they did this because higher intensity easily caused bleeding gums. The setting for beam or rotation is done by a switch on the head, with the beam being the most effective in my case. It also has a water flow switch on the handle, obviously for a short time, as it does not stop the pump.
In practice, personally, I have some teeth with large gaps and some so small that floss does not pass through, but water can pass through the base of the gums. In these cases, the device is useful, but it lacks the necessary intensity.
The 600ml reservoir lasts for about 1 minute of use at intensity 5. However, you can have a glass and fill it until you finish the entire mouth, in a maximum of 3 minutes. Besides, a larger reservoir would not be convenient.
If someone wants, they can add, for example, a small cap of mouthwash, but personally, I would recommend doing a regular rinse after brushing. If you add it inside, essentially you are throwing it away, dissolved in water. Adding baking soda would definitely have an effect, but you risk damaging the device's pump.
For those who have braces or retainers, I imagine it can be necessary, even for daily use.
Currently, the company offers 100 days of customer satisfaction, with a money-back guarantee, for all OralB devices.
