So far I am satisfied with the product; I will withhold further judgment until I have my next dental check-up. The hygienist recommended the product to prevent the possible progression of gum disease/infection.
Having Waterpik at the sink got me in there, and the toothbrush was right next to it, so I started using both. Every day! Nothing before has ever caused me to change my habits! I love using the warm water and seeing pink healthy gums as a result!
