I had been having problems with bleeding gums over one tooth which also had a receding gum pocket. after 4 days of use, the bleeding stopped. the gum pocket has gone away. my gum is back to normal. when I use it I put a cap of mounth wash and a cap of peroxide in the water and use 2-3 times a day. awesome results.
We have used the Waterpik for several years and because of its effectiveness I have been able to go from every 3 months for deep cleaning to every 6 months. It really has been good for us.
It does an excellent job at whst it does. I dislile flossing, but using this makes it veey simple. I hsve 2 suggestions, fist is that the top tip holder only holds 4 nestly, the other 2 tios are on the machine or loosely placed in the top containrr. The other suggestion is to make the power cord a little longer.
