I have found this tool very helpful. I tend to store plaque more since I "got old" and felt i needed help . This seems to remove the plaque well. Don't do it all at once. Just do a little each day until you feel it's gone. I found this to work best. Great company. Made sure I received the product in good condition. It was!
So yeah I was very skeptical. I have issues on my front bottom teeth with stains as I got older with coffee and such. It was pretty embarrassing. I figured I would give this a shot. I used very light pressure and I was amazed. After a minute or so I saw the stains just start to go away a few more minutes spent and I can now smile and not worry about the embarrassing stain on my lower teeth.
Very easy to use and just enough abrasion to polish nicely. Some polishers seems very flimsy or others feel like you're sanding your teeth. Easy to switch tips. Overall, good for the price.
Works fantastic. Just go along the gum line while it vibrates and all the yuck comes off.
