Query: I love my Sonicare Toothbrush

This is the second one I have gotten. They last a long time. My other one was 5 years old. It is great. I love how clean it gets my teeth. Since I have had one and have made an effort to also floss nightly, I have not had any cavities. Definitely takes the stress out of visiting the dentist...and I have had many cavities in my lifetime.This time I bought 3 sonicare toothbrushes, One for me and I gave them as presents to my sister and boyfriend. They love them too. My sister has gum disease and she says it is making a huge difference and my boyfriend uses smokeless tobacco and he also says it is helping. Says his teeth feel clean even right after waking up.Definitely recommend the sonicare toothbrush! But if you can get the one with the quadpacer. My original one had it, this ones does not. It just beeps to tell you when to move to the next area of your mouth, doesn't sound important but it does help.
