This is my first water flosser and it has literally helped me saved my gums and teeth. I use distilled water in it and not tap water to avoid corrosion in the machine and attatchments.My teeth feel so clean and my gums have been slowly getting better. I can't thank you enough for this amazing product.
Use room temp. water and always have your machine unplugged when setting up. This has been one of the best dental products to be introduced to and be in a relationship with…period.
